Window World 4000 Series Reviews And Prices
Why This Review Is Difficult: Here is the problem with trying to review the Window World 4000 series. The company has over two hundred branches/franchises and they don't all sell the same window series. So the 4000 series in Dallas might be a completely different window than what's labeled the 4000 series in Denver. I'm not privy to how the process works, but I'm assuming it has to do with the price point the individual branches get from the company.
At one point, the 4000 series was the ComfortWindow 4000, but WW seems to have gone in several different directions. Some 4000 series are really the MI 1650 and others are the Alside Mezzo Windows. In the past year, WW has begun selling Simonton Windows in certain cases, so that adds yet another wrinkle.
As a reviewer, it's hard to write a review when I I don't honestly know what I'm reviewing. However, what all of these window series have in common is their overall quality level, which I would put at roughly a 5 out of 10. This is not bad, but certainly not impressive. I think there is a place for the WW 4000, but it will be based on a case-by-case basis.
Bottom Line: The WW4000 series is going to be a plain middle-of-the-road vinyl window series.

Window World 4000 Series
Window World (and others like Castle Windows in the northeast) offer teaser deals at very low prices for their entry level window - typically an MI 1650 or Alside Mezzo. Contractors are not typically keen on builder grade windows in general, and these are no exception.
The issue with the 4000 series centers on the snap in sill, which can over time trap moisture and debris inside the frame. Not a great design, but the snap in sill is cheaper to make than a true sloped sill. The performance numbers are not great here either, especially the air infiltration, which means the unit can let in air through poor seals and weatherstripping.
In my opinion, this window is probably best for rentals or house flips. For better long term value, you should upgrade to a nice mid range vinyl option like the Milgard Tuscany, Simonton 5500 or Wincore 7700 series. I would give the Window World 4000 Series a 3.7 out of 5 stars rating.

Window World vs Renewal By Andersen
Hi Dane. I’m curious what your opinion is on Window World? The branch here in my hometown gets really good reviews and I’ve got a bid on the 4000 series and the price is considerably less than the two other bids that I received. One was from Renewal that was about 2 1/2 times as expensive as the WW quote. The other bid was from Alliance windows which I’m a little bit confused on what they are. Anyways, I was just curious how you would rate these three companies.
Barbara - Homeowner - from 2023
[Site Editor's Answer]
Barbara, often times Renewal is quite expensive. It’s not that uncommon for their bids to be 2 1/2 times that of a WW. In terms of Window World's quality, this is really going to depend on the branch near you, which sounds like they have a pretty good reputation. Some of the online reviews and ratings can be manipulated, however, I tend to believe that if the reviews are over say 80, then you’ve got a pretty good cross-section of legitimate reviews and they should give you a pretty good idea of what you can expect in terms of customer, service and installation quality.
In the past, I have tended to rate window world pretty poorly. However, in the last year or so, WW has been stepping up their game, in terms of the brands they offer to their customers. Specifically, their use of Simonton, which I think are a very solid mid range vinyl window option. In addition, they offer the Wincore impact window, Which again is a good mid range impact window option.
So I think, for me, it really comes down to what they’re actually selling because they always sell under their name - window world 3000 series or 4000 series or 6000 series. But that doesn’t tell you what you’re actually buying, which I always find very odd. Assuming that your WW has a good rating/review and assuming they sell a Simonton, then I think you should consider them.
Alliance is always a little bit of a grab bag for me. Essentially, they buy window parts and components from a single supplier, which allows them to keep their prices relatively low. However each company that sells alliance windows does so using their own factory. So it’s difficult to speak to the quality control issues within a specific factory that is using essentially alliance window parts. Does this make sense?

Simonton 5000 Series
Yes, I did contact the three companies you mentioned. Two responded that they do not carry triple pane, and one did not respond. Seems like my choices are between Window World (carrying Simonton 5000 series) and Pella. Pella in San Diego seems to have horrible Yelp reviews though. I will keep you posted. Again, Dane, thanks for doing this for the good of the public. I hope you're somehow compensated for this, in good karma, health, and all else.
Last question: what are your thoughts on the Simonton 5000 series Craftsman retrofit?
Gratefully.
Tonya - Homeowner - from 2023
[Site Editor's Answer]
Tonya, thanks for the nice words. The Simonton 5000 series is a solid option for sure. I would pick this over the Pella 250 series for sure! It sounds like this is your best bet! Triple Pane Windows Cost

Window World 4000 vs 6000 Series
As I reread my email, I did not mean to sound disrespectful of your opinions; but rather am so frustrated at the response I have received.
So, could I ask in a more pleasant tone, what do you see wrong with Window World 4000 vs 6000 series (which Consumer Reports favors)? I do realize that installation is very important in replacing windows; however, their estimator seemed the best informed and professional of all that have been in my home.
Thanks for your assistance.
Nancy - Homeowner - from 2023
[Site Editor's Answer]
Nancy, I understand the frustration. WW often sells a subpar window, although some of the branches lately have begun to sell a Simonton, although I'm not sure which model. Simonton is a solid mid range window brand, which when coupled with good installation, should serve most homeowners quite well. I checked and your local branch does get good reviews. If you could find out what they sold (not what they "call" it, but which relabeled window it is -- then I could give you an opinion on the quality.) Sometimes they hem and haw about instead of telling you what you are actually buying. It's bizarre.

Your website has been super helpful in reviewing various windows, with that said we were wondering out of these three replacements, can you let me know how you would rate them 1-3 as your picks.

Belen, absolutely I can rate them. The Soft-Lite Ultraview, the Bellevue, and then the 4000 series. Of course, I’m sure that the price quotes are reflective of these differences. If you provide me the prices and the companies, I’m happy to factor those into the equation as well!

Window World 4000 Series Reviews
Good Morning Dane, I live near Portland Maine and am looking at replacement windows for our house built in 2001. As we have nice inside window trim we want the replacement windows to be installed from the inside.
We received a quote on the Window World Series 4000 DH for $1200 each. Can you confirm whether they make the windows they sell? From doing some research they don't seem to be good, especially for the money. Has their design and quality improved in the last few years?
We received another quote for $1000 per from a local installer and they are Alside Series 6000 DH, which have mixed reviews.
Can you suggest a good manufacturer and installer in our area. We are older and do not expect to be living here for more than 10 years, but still want a quality product.
Thanks for your help.
Peter - Homeowner - from 2023
[Site Editor's Answer]
Peter, hi, that's a tricky timeline in that your ROI won't be all that great having said that, the WW4000 series is often the MI1650 (Window World has been changing their suppliers as of late sp it's tough to tell what your branch is selling -- weird right????) -- a pretty poor quality series in my opinion. Maybe concetrate on my "good" list below with your timeline...

Series Question
My question is my mother purchased WW, that were supposed to be the double hung 7700 series. Do they even make a 7700 series because the booklet I'm finding is a 4000 series and it shows nothing about a wind resistance rating I would like to know more about the windows and whether or not my mom got taken.
James - Homeowner - from 2022
[Site Editor Answers]
James, WW sometimes does sell the Wincore 7700 series, but it's much more liekly that they sold you their 4000 series. Do you have the paperwork? If so I would call up the WW branch and ask them to look it up in your system. I would get their number and send them pictures to let them confirm that she received what she paid for.

4000 Series vs Polaris ThermalWeld Plus
Hi, Dane! I just found your site as I'm comparing my replacement options. I have similarly priced bids for Polaris ThermalWeld Plus and Window World 4000 series. What are your thoughts?
Make it a meaningful day!
Chris - Homeowner - from 2022
[Site Editor Answers]
Chris, the Polaris ThermalWeld Plus is the far superior option ove the WW 4000 series. This is a no brainer for me -- but do make sure that Polaris installer has good to great ratings and reviews online as the installation is half the battle.

4000 Series Cost
Hey Dane. Looking at replacing 7 single hungs. I have quotes for Sunrise Restorations at $1050 each installed, ProVia Aspect AP500 Series for $630 each installed and window world 4000 series at $685 each installed. I’m waiting on a quote for ProVia Endure.
Plan to be in house for 10 yrs. The ProVia ‘s seem to be a steal and it’s a long-standing local company selling a few miles from my home with installers that are not subbed and have been with them for some time. Any strong opinion on the ProVia? I know it’s not your beloved Sunrise Restorations but would you say it’s a decent vinyl window? Worth bumping to the Endure? Thanks!
Efron - Homeowner - from 2022

Efron, I would definitely go with Provia Aspect Windows for $630…great price and very good option…especially given your timeline…

Window World 4000 vs. Apex Insignia
Hi Dane, I’ve been reading your reviews. We live in Alpharetta (north Atlanta suburb) and we are looking to replace all the windows of our home. Can you comment on the quality of the WW 4000 series and Apex product?
We’ve got few quotes from window world, Apex and 2 others, but I’m interested in your recommendations for a good quality product/company at the best price.
Thank you very much.
Raluca - Homeowner - from 2022
[Site Editor Answers]
Raluca, the Apex Insignia is a good option, but not great. They are certainly a decent option though if the price is right.
Most everything that WW sells is pretty poor and not something I would expect to be problem free after maybe 10 years.
Here are my Atlanta recommendations for your consideration:

WW 4000 Series In Baton Rouge
Good Afternoon, I came across your website Replacement Windows thank you for sharing your comments and reviews. I am located in the New Orleans area, and I am looking for 21 replacement windows. For a little back story, I owned and operated a commercial glass and glazing/door company for 30 years. With that said we stayed away from residential work my knowledge as it relates to vinyl windows is limited I’m okay with all the other glazing industry terminology.
I have a price from WW. However, I am very concerned about their reviews. The local independent WW company is located in Baton Rouge LA and it's hard to find any Review above two stars for the installation. WW quoted me using the 4000 series did not offer any other series.
I also received a quote from Anderson that was so out of the ballpark. At a high level for each window was approximately $2800. I could still commercial storefront impact rated for this price.
You mentioned in a few posts you have a recommendation list. I would appreciate it if you would kindly provide your recommendation list for windows and/or companies that will service/install in the New Orleans and surrounding area (specifically North Shore).
Thank you for your assistance.
Javier - Homeowner - from 2022

Javier, I would probably stay away from WW myself, especially if their branch reviews are poor. LA. is a tough nut for me to make any recommendations. However, I believe there is a Sunrise rep in New Orleans...that's where I would start...I'll get his information for you...

4000 Series Reviews
Hi Dane, thanks so much for your recommendation, we did get a quote from Zen and we think the prices are good and compatible. We really want to have good quality window as we will be living in the house, the price for both are not too far apart and both companies seem to have good reviews in the Nashville area. However some technical question surfaced:
1) the window world provide the information for their energy performance and seems to have excellent air leakage to be < 0.3 , while zen reply with their to be Nirvana is 0.07 cfm, Karma is 0.10 cf. I am not an expert but does it mean the glass of the Windows world is performing better when it comes to holding in the air which will mean it will be more durable ? see below image from window world .
2) I notice the window world does not have a form filled main frame when compared to Nirvana, but they say it is possible to add $60 each to have form enhanced main frame ? Will that make the quality of the frame and window comparable? Please advise thank you so much!
Ting - Homeowner - from 2022
[Site Editor Answers]
Ting, just to be clear the Window World is saying their AI is less than 0.30 -- while the Nirvana is 0.07. The 0.30 is a generic term -- WW doesn't advertise the exact AI. The WW 400 series probably has an AI around .17, which is not great. I would say .07 is quite good and anything below .05 is excellent. AI is a term that refers to how much air is able to get through the window essentially -- how tight the unit, and is an important term.
A foam filled frame is more about adding strength to the main frame and sill than about energy efficiency, but it does help a bit with the performance data.
If you are going to be in your home long term, I would say go with the Zen Nirvana or consider upgrading to the Lotus, which is typically a Soft-Lite Pro and a bit better window. The WW is too much a gamble in my opinion.

Window World 4000 vs 6000 Series
Hello, I was reading your reviews and appreciate your transparency. I have had Pella, Marvin, represented by Amazing Exteriors, Kensington represented by Statewide Remodeling, Window World and Ecoview representing with NT windows.
Window world presented the 4000 series in double Pane windows, and only offered the 6000 series in a triple pane. I don't think I need a triple pane window in Texas? Thoughts?
Do you know anything about the other companies? I would love to get your recommendation on window types and comparisons.
I appreciate your time, all of the Window World Reviews, and your assistance.
Scott - Homeowner - from 2021
[Site Editor's Answer]
Scott, I like the Kensington windows the most of the list your sent. Their windows are really well built. Statewide Remodeling in Dallas gets good, but not great reviews. A contender for sure.
Amazing Exteriors gets quite good reviews, but Pella is generally overpriced in my opinion. Marvin is a well made product, but you will pay quite a bit for their fiberglass windows. Definitely worth it if you can aford it -- but a high quality vinyl window offers better value in my opinion.
NTex windows in Dallas -- I don't see many reviews, their branch in Houston seems to get high marks -- but I don't know enough about their Ecoview windows to give the product a thumbs up.
I would generally pass on the WW option, especially seeing as you have some nice options in your area.
Here are my general Texas recommendations for you to take a look at...

Window World 4000 vs Champion Windows
Thank you so much Dane. Here is the list for 18 windows.
World of windows using 4000 double hung using solarzone elite glass energy star package has the cheapest bid at $11,640
They seem to have a decent limited lifetime warranty at least through the store but only 5-year warranty through corporate. I do not really want to go with the cheapest but I'm having a hard time seeing if the quality of the other bids are worth it? I'm fine with paying more money if it is a better product. It's so hard to tell
Zen Windows using Nirvana double hung soft-lite classic plus double strength, double pain, solar low E, argon gas, stainless steel interceptor spacer system at $15,564
TruGuard using Potomac low E double hung energy star glass $21,709
Champion double hung $23,000
Universal windows double hung $17,000
I'm also getting a quote from Lowe's for Pella if you think that is a better product but I'm not too impressed with there warranty so far.
Thanks so much I really appreciate it I trying to look at what spacers they're using what type of vinyl etc and they all seem to be 100% virgin vinyl and they all claim to have the best spacer of course
Tina - Homeowner - from 2021
[Site Editor's Answer]
Tina, if you don't plan to be in your home more than say 7 or eight years, then consider the WW 4000 series. Any longer than that and I would say the best long term value of the bunch is the Soft-lite Classic plus through Zen at $15,564. The company has fantastic reviews (Zen Windows Carolina, correct?) and the Soft-lite Classic is equal to the Champion window in my opinion. I know the cheaper option is always the most attractive, but the better long term option is the Zen in this case.

WW 4000 vs Mezzo
This whole business is so confusing! I don't want to make the wrong decision on a lifetime investment. I was just speaking with the installer of the Alside Mezzo. He said the window world is also the Alside Mezzo, but that it does not come with triple pane. I'm guessing here that the Alside Mezzo 3001 Triple Pane is basically he same frame as the WW 4000 series, with the higher specs coming from better Low-E and triple pane? At the same time, you said the Mezzo triple pane is better than the Window World 6000.
James - from 2021
[Site Editor's Answer]
James, the WW branches do sell different window series so it’s hard for me to know exactly what they are selling at which branch. This was what I thought was the latest…
WW 3000 MI1650 Series of AMI Series
Window World 4000 (Whatever step up they are using…)
WW 6000 Alside Ultramaxx (or apparently the Mezzo series)
The triple pane would offer a better U-value and SHGC.
The Alside Mezzo is a decent mid range window. Until recently they didn’t offer this series in the triple pane and I assumed it was because they didn’t feel like the frame had enough strength to support that weight over a 20 year period i.e. you might see some eventual bowing in the frame over time…
I’m going to include my good and great list just one more time. I can’t remember if there was a dearth of options in your area…

Window World Prices
Hi Dane, appreciate your informative site. I live in the middle of nowhere in NC (halfway between Asheville and Charlotte). I had the WW franchise in Asheville quote 12 double hungs. Their price was $9700 which sounds outrageous.
Also bothered me that when I asked the salesman if they sourced the windows from the same place as before he claimed they manufacture their own windows in PA and NC. I don't have many options here, Charlotte companies don't service my area and all local remodelers are booked solid and won't answer calls. Any helpful tips for me?

Michelle - Homeowner - from 2020
[Site Editor Answers]
Michelle, if you are going to be in the home 10 years or less, I would go with the WW bid. This is assuming that your local franchise has a good reputation and good online reviews. If they don't, then you have to go back to drawing board because paying $1000 a window is crazy for your purposes.
I would find a Simonton dealer in that case and get a $500 window. Have you tried to find an Okna dealer and see if you can get a quote on their 400 series, which is their entry level window. Still a good window.

4000 Series vs Zen
Hey Tim, I'm looking for some help. We are planning on selling our house in 5 years or so, so we are looking for windows to get us through that time without the next buyer being concerned about window credits or replacement windows. We are located in Kansas City and are considering two companies, WW and Zen Windows.
My question is, is it a good idea to get the 2000 series or zen karma given our timeline, or are still better off going with the 4000 series or zen nirvana? Again, just looking for something "good enough" for 5-7 years.
I appreciate any help and advice you provide.
Jess - Homeowner - from 2020
[Site Editor Answers]
Jess, with a timeline of 5 years, it's tough to justify going with a good window like the Zen Nirvana over the WW. You're probably not going to see much return on investment, unless you tell the buyer you put in new windows that were Soft-Lite Classics. I hate giving this advise because Window World's window are not nearly as good as what Zen sells (usually an MI 1650 or an AMI series).
If this were my house, I would be mighty tempted to buy the low end Window World and be done with it. You probably won't have any issues with them for the first five years. Again, this goes against my overall approach to providing consumers with the best bang for your buck, but in your case this might be the right approach (unless you get a buyer who values quality home improvements).
Tim - Site Editor - from 2020
[Jess's Reply]
Tim, we ended up choosing the WW 4000 series. The original quote was 19 windows for 11,106. We ended up negotiating a bit and they lowered the price to 10,451. Zen Nirvana came in at 12,700. We didn't have the WW 2000 series estimated because the price difference was negligible at best. We were more comfortable with the 4000 holding up for 5-7 years.
I appreciate you getting back to me and providing some advice.
Thank you.

Window World 4000 vs Simonton 5050
Hi Dane, we replaced a few windows this past summer and are now getting quotes to replace the rest. About 11 average size and 2 bathroom windows.
Central Florida
My first quote today from FAS for Simonton Reflections 5050 was $10,500. It seems a little high to me
I did some research on your page I believe and found some specs, the U factor to be 37
The windows we had replaced this summer are Series 4000 from WW U factor on label is 27
I'm getting a few more quotes next week including window world. From the invoice their windows should run about 584.00 each the FAS quote was 800.00 each
Which is the better option here?
Thanks.
Len - Homeowner - from 2020
[Site Editor Answers]
The Simonton 5050 is the better choice over the WW 4000, which is probably a MI1650 series. Neither is all that great though and that seems like a lot to pay for a just okay window.
I'd get a couple more bids. Maybe another Simonton dealer on the 5500 Reflections, which is the upgraded model. Maybe a PGT dealer on their 5400 single hung (a good single hungw). And maybe a Custom Window System dealer on their mid range vinyl window model.
I think three more bids will show you where the marketplace price for your project should be.

Window World vs ABC Supply
I have 13 windows and three bids. One is from WW of Winston Salem for $5200, one from ABC Supply company for $4300 and the last one from a local dealer for the Simonton Prism Gold for $4700.
Love to get your take. Thanks.
Sonya - Homeowner - from 2019
[Site Editor's Answer]
The Window World bid is the highest and probably not the bid I would go with. I would probably pick the Simonton Prism Gold for $4700. The ABC Supply doesn't provide an actual window so I can't speak to that.

Window World 4000 Series Reviews
Hi Tim, I have been getting multiple bids for my 19 windows in my home in Minnesota. I have been interested in Simonton 5500 or 6500 from home depot. The prices from contractor for these windows came in around $17 to $22k. Window world with their 4000 series came in at $15k. Then the sub contractor who installs Window World came in at $11K.
I read your site and told him there are lots of window world bad reviews and I prefer the Simonton 5500 or the Pella 350. His response was that WWd switched from AMI to MI in manufacturing their windows about a year ago. He informed me that he wouldn't trust AMI but loves the quality of MI. He loves it so much that he installed them in his own home. Is there any truth to his merit? How does the new window world 4000 vs 6000 series stack up to the 5500?
Let me know if you any questions.
Thanks.
Subash - Homeowner - from 2019
[Site Editor's Answer]
Subash, I would say the move from AMI to MI is an improvement, but most window installers I know regard MI as a builder brand of window (a cheaper lower end manufacturer). You can see that in the pricing. I'm not actually up to date on how window world 4000 vs 6000 series stack up specifically, so I can't speak to those specifically. I would say the Simonton 5500 would definitely be the better window than anything MI makes, except perhaps their MI Energy Core series, but 19 windows at $17K is expensive to begin with. I've never been a big fan of the Pella 350 so I'm a bit stuck here.
Have you had any other bids other than WW and Home Depot? HD price quotes can actually be quite high, or at least I've noticed that trend lately, which is surprising to me.
I know Sunrise has dealers in Minnesota and their standard vinyl window is very good. I'd love to know the bid price they give you.
I would say this: you get what you pay for with Window World, which isn't always the worst deal if you don't plan to be in your home long term or the branch in your area has a really strong reputation. However, I always caution that when little things start breaking down on your vinyl windows come winter of year 7, you should't be super shocked.

4000 WW Series vs. Thermal Windows 9000
I have a manufactured built in 2007 that needs 11 new windows. Of the three bids I have, one is to simply cut out the old vinyl windows and put in replacement windows. However, I'd rather have the windows completely taken out and the windows with the flanges put in. This is more expensive though because they have to remove the siding.
I got a bid from on the WW 4000 window with low-e glass, argon, and grids. The bid included removing all the siding and putting in new construction type windows. This was $6000.
Got another bid from Window Depot for Thermal Windows and Doors. Their estimate was $7150 for the 9000 series with a triple pane glass and also included the removal of the siding etc.
Jack - Homeowner - from 2018
[Site Editor Answers]
Jack, it sounds like removing the siding and replacing the windows with the nailing flange is the way to go. The second bid is the clear winner in my mind. I'm just not a huge fan of the Window World 4000 series. Have you checked out our Window World reviews? I would advice that you check them out!

Lisa Ann, these are indeed two very very different bids. One is a top end wood window and the other is a low end vinyl window. For most consumers I advise something in the center of these two bids -- unless you want an expensive wood window or you are leaving your house in less than 7 seven years in which case a lower end WW window is good.

Window World vs. Windows By Unlimited
I live in Wisconsin and need 34 windows replaced on the mid century modern house we just bought. I have gotten to quotes from window world and unlimited windows. They are about the same price, but do not know which is a better window? Double pane, low e, argon gas all vinyl. We have 26 casements and 8 hoppers.
I can not find a lot of information on some of these windows.

Jim, there should be plenty of information on WW out there. They generally sell a low end vinyl window at a very "competitive" or low cost price. I don't know a lot about Windows By Unlimited, but they look like a similar outfit in terms of the quality and price of the windows they install. Basically it appears to be a lower end vinyl window at a low end price.
I personally think this approach is risky for consumers because when and if things go wrong with the windows (like broken seals) come year 6, 7, 8 etc. you have to hope that the company is going to adhere to the warranty on the windows.
I would prefer to go with a local Okna, Sunrise, or Soft-Lite dealer who sells a high quality vinyl window for more money, but you have a much lower chance of something going wrong with the windows or the installation.
If you do go the Window World / Windows By Unlimited route, I would google the specific branch, so for instance google "window world Green Bay Wisconsin reviews." I would only go with a company that had good yelp or google reviews and had been in business for the longest period of time.
Good luck and let me know how it goes!

Window World Reviews
I need 14 new double hungs and a single sliding door and so far have 3 quotes. The Window Nation Grandview ($15,445), WW sold me on the 4000 series ($8985) and Window Source sold me the 9000 series ($11,565). Window Source reviews
Any advice on these bids?
Debra - Homeowner - from 2018
[Site Editor Answers]
Debra, the Grandview window is quite good, but it's not the best price I've seen. The WW 4000 is their low end series and not one I would go with. You may want to see if they will quote you out on their premium window and see how this fares. WW is a franchise so I would check the reviews of your local branch to see if they have positive or negative reviews.
I don't know enough about Window Source to even make a judgement.

Window World vs Champion
I am looking for a sanity check on a window bid. Is this something you could help with?
After a long chain of events that included cancelling a contract for Sunrise Essentials, I now have an offer for 8 sunrise restorations double hung vinyl windows (4 with grids; 1 tempered and obscured) all 32"x73" for $5500. On the write-up the options are only listed as "with low-e, argon gas, polyurethane frames, and latch lock plus."
Is this a fair and competitive price? The other bids I have are probably not of comparable windows and I don't have many sunrise vendors locally to call. The other bids:
1) Window World - $3200 (probably not the quality I'm looking for)
2) Champion Windows Prices - $5900 (I didn't like the sales approach from Champion)
3) Local Company (didn't even mention brand) - $3800
4) Revere Berkshire Elite - $3592
Heather - Homeowner - from 2017
[Site Editor's Answer]
Heather, the $5500 bid for the Sunrise Restorations is in the ball park of fair and is the best window of the five. The Window World is poor quality, the Champion is good but too much for that quality. The other bid I like is the Berkshire Elite for the $3600. It's a mid range vinyl window, while the Restorations is one of the best vinyl windows on the market. They are probably equivalent at the per window price. So the question is do you want a not bad mid range vinyl option or a really top rated vinyl window.
If it were me, I would try to use the Revere bid to see if the Sunrise dealer will drop his price. If he gets to say $5000, I would definitely go with the Sunrise option.

Window World vs Sunrise
Hi Dane, You may have received the email below. I forgot to mention that the Sunrise are Vanguard. What is the intercept space made of?
We need to replace 30 all wood Pella casement windows that are 30 years old. (some of the sills and sashes have rotted). We are considering Window World casements vs Sunrise vinyl. Are these windows in the same category? Are Window World's casements made by AMI? I saw in the WW catalog that they use a metal spacer and from my researching read that metal is not the way to go.
My husband wants the Sunrise with triple pane because they come with internal blinds (like we had with our Pellas). I have just read about the green tint and lower VT ratings of triple pane glass. I don't want to spend a lot of money because we will eventually need to sell the house, having been here since 1975. I am interested in a company with a lifetime warranty that is transferable to new owner.
The dealer was trying to sell us on the Elements Soft-Lite windows but I don't think we need to go high end at this point in our lives. That's when we noticed the Sunrise window in his showroom.
Would you please offer some guidance? Thanks so much. Sunrise Windows Reviews
Jan - Homeowner - from 2017
[Site Editor's Answer]
Jan, the Intercept spacer is made of a tin plated stainless steel and is considered a warm edge technology. It's a good spacer. Window World uses AMI windows, which owns Alside. The 4000 and 6000 are not very
good windows. The vinyl extrusions and components they use are low end, the metal spacer is just one example of this.
Sunrise window costs are often very good and the Vanguard and Element use the classic Sunrise frame, but both add some very nice upgrades. The Vanguard and Elements are both great windows, I wouldn't sweat which one you go for.
If I were selling my house in five years or less, I would be very tempted to go with the WW because you won't get your money back with the extra you spend on the sunrise. Don't worry about the transferrable warranty, when you are selling your home no one pays any attention to the windows -- or if they do it's a single sentence that gets a head nod.
If you are selling your house in five years or more, I would go with the Vanguard. Excellent window.

Window World Complaint
I sent our Window World complaints customer service tonight. I never complain. But I expect to get what I purchased and if there is a warranty, I expect the company to support their product.
So, I purchased 9 sliders in the fall 2014. Dec 2014 it got below 19 degrees. Ice froze to the glass on the bottom of all windows going from the center over to the walls. Then I called Window World and they sent the sales person that told me I had high humidity. In Feb. the problem became worse. In Cincinnati Ohio, our winters are wet and cold. Not dry and freezing. So the outside humidity is usually high. I complained and had many reps come to my home. They agreed that I had issues. It was decided I needed new sashes.
The sashes were replace with the same manufactured sashes as before. The problem repeated itself through the 2015 winter. I complained and finally the owner agreed that the windows were possibly not manufactured correctly and the installation was not done correctly. No foam insulation or cold barriers were used. New windows were finally installed Oct. 2016.
Problem repeats again. I can see day light between the sliding window sashes. Furthermore, I can take the inside of a ball point pen and go from the inside to the outside of my windows. These windows are not air tight -- right? If a pen goes through then logic tells me air and humidity does as well. I had a professional test the windows with his thermal imaging camera. It proved my point. Window World will not return my money.
In winter 2016 one of the reps agreed that I had air coming in through where the sashes meet. I was told not to close my shades as they are trapping moisture. He applied sponge thermal tape saying they would fix the problem. Months later, since there is no answer except to change design, they refused to help me.
I have attached a report with thermal images of heat loss and trapped humidity between inside and outside walls.This report also shows the holes. I had these tests done twice by two totally different companies. Both found the same results. Yet Window World wants to blame my drafts and ice on my furnace.
I heat with oil. My basement is so dry the dehumidifer never turns on. The walls and floor are painted and sealed. I have a sump pump that never runs unless it rains for more than 3 hours. I live on a hill and all rain water runs down towards the creek and never stays under my basement floor.
Then I had an HVAC professional come and check my oil furnace for humidity leaks. There was none. Report also attached Actually the inspector told me the air coming from the furnace was too dry. If my windows didn't leak I would need a humidifier or I would have nose bleeds. Well, I did before 2014.
I had a furnace sales person stop in just to see if he could find mold any where in my house. He also checked for chemical residue and other pollutants. He tested the inside walls in my home for humidity levels and then moved towards the windows. The humidity doubled by the time he reached the windows. He agreed that the humidity is coming from the outside in. It is not coming from something inside this house.

Window World vs Vista
Hi Dane, I was hoping to find Vista Panorama windows on the list for comparison, but I have read a bit about Vista on your site and I have seen that you indicate it is a mid range "pretty decent" window. I have a quote for $920 installed for 2 double hungs and one picture window with Low E argon, .29 double hung to .26 picture.
Considering adding more double hungs and the quote installed was $288. I'm getting calls in now for more quotes (from your site), but the other quote I already have is WW 4000 series with solar zone glass and foam filled frame for $1,364 (same 3 windows).
I'm pretty sure the Vista quote is a great deal, but I know I get what I pay for. Didn't see them listed on your attachment. I think the contractor is giving me a great deal and not sure if I'll come close on price anywhere else, but wanted to make sure you truly thought it was "decent". If not and I could spend a little more to get something that is truly better, I'd be open to suggestions. I'm in central VA by the way.
I do have some rental properties and has Vista Panorama put in a rental 18 months ago by same contractor. My tenants there love the windows and feel no draft at all. House is nice and cozy. One thing they did mention which I checked out was that if you open a window and then go to push the bottom sash down, the top sash comes down just a little.
You twist the lock and may think it's locked if you don't check it. It is quite necessary to push the top sash up while pushing the bottom sash down to get the lock latch to engage to lock it. Regarding materials, I did notice that the twist lock handle is plastic or vinyl and not metal.
Angela - Homeowner - from 2016
[Site Editor Answers]
The Vista Panorama is loads better than the WW 4000. The price quote you received does sound very solid. I like the fact that you have a contractor who has installed the window before, because he (hopefully) knows all the little tricks that may come into play with the installation.
In terms of the top sash falling when trying to close the bottom sash, this is something that happens on a number of windows as they age and the problem will usually worsen over time. It is one of those “you get what you pay for” annoyances.
This isn’t a deal breaker though and if you like the Vista Panorama, then go for it. I would suggest having your contractor talk to the Vista rep when he is ordering your windows and see if you can have him address the issue with the sashes. The rep will be more likely to help out if he thinks he is getting an order (I know that sounds sad, but it’s often the case.) See what he says about the sash before you order and perhaps you can get some satisfaction.

WW vs Milgard
Our daughter and a neighbor used world of windows 4 and 3 years ago. Both are very satisfied so far. WW has replaced 2 windows for our daughter one due to a technical issue with the low-E coating one due to breakage from an accident. All costs were covered by the warranty. According to the warranty all costs for any type of failure are covered lifetime.
I have contacted a company that uses Milgard windows and will get an estimate from them based on your very kind professional recommendation. We will see what they have to say regarding cost, installation, etc. I will let you know when we make a decision as well as how the installation goes with this company just so you can expand your data base. If it is not of interest to you you can just discard it. Once again thanks for your informative and rapid reply.
Dean - Homeowner - from 2016
[Site Editor Answers]
Dean, thanks for the info, our job is to post ALL consumer information so that homeowners can get the best long term value for their hard earned dollar. WW is a franchise so each one is privately owned, and I have definitely heard of quality dealers out there. My point wasn't to disparage WW, they offer a fantastic price point and if they honor their lifetime warranty on all their windows, then I have to say it would be hard not to go with a $200 installed window.
My issue is with so many homeowners contacting me and telling me they bought cheap vinyl windows (not WW per se, just "cheap vinyl windows" of which there are lots out there) and now they have little recourse because the authorized rep has vaporized into the ether and the company won't field their calls. They basically threw their money into a hole.
If the Dallas branch of Window World offers good installation and backs up their warranty with solid service, then that's something that homeowners in your area should know about (and i will absolutely post). However, the Alside Excalibur window (the WW4000 window) is commonly regarded by many window installers as one of the cheaper and less well made vinyl windows out there, so come year nine and ten, they are prone to quite a few issues. If the company continues to replace them, then that's obviously a good thing.
Let me know what you decide -- I'd love to hear about your experience, positive or negative!

Window World vs Ply Gem
I am trying to decide between Ply Gem Premium Series and WW 4000 Mezzo. I will have both casements and sliders. Which option is better?

Barb, the Ply Gem premium is the better option between these two. The WW Alside Mezzo is not bad per se, but the Ply Gem Premium is I would say a better built and stronger window overall

Window World vs Sunrise
I am needing some advice when it comes to windows. I am in the process of receiving quotes. Should have a total of 5 by the end of the day. The suppliers are Window World, Sunrise (& restorations), Universal Windows Direct and Champion.
I am going to replace most of my windows (28 in total – 8 will be picture windows, rest will be either single or double hung). 15 of these windows, get full west sun. 6 of these will be upper level picture windows.
Window world double hung 4000 series, with a solar shield package, gave a quote of around 15k, after speaking with some other people that have recently installed windows with them, there should be considerable flexibility in that price.
Restorations windows, 20 double hung, (8 picture windows) with the 12 layer coating quote was 27K.
Sunrise, Sunrise windows with the 12 layer coating package, 20 single hungs (8 picture), was over 17K (636 each). They said the only difference between the restoration package and the sunrise package is the outer frame is not insulated like the restoration style. Also a difference in the locking mechanisms.
Also planning on replacing a patio French door. Changing out a 2 6'8" doors with transom, to 2 – 8' doors. Window world gave a price of $3250 for a Therma tru door, and the sunrise installer gave a price of $4932 for their steel door. Their brand is Provia.
Any suggestions? To me, I prefer the quality of the restorations and then the sunrise, and believe I will get a good install from that company. But I also think the price is very high, especially considering 8 of them will be picture windows. I am considering counteroffering, but I would like your opinion of the sunrise/restorations vs the other brands. The Universal Window Direct supplier in the area, has good reviews.
Thank you for any help,
Angie - Homeowner - from 2016
[Site Editor Answers]
Angie, I'm not in the habit of recommending WW -- I don't think their windows are well made and don't offer the sort of long term value that make the initial low cost worth it. The Restorations price bid sounds high to me. The Sunrise on the other hand is a great window AND its nearly the same price as the Window World 4000.
In terms of the doors, I would also not recommend WW (are you sensing a pattern here), but I might get another bid from maybe a Simonton or Jeld Wen -- if for no other reason then to take it back to the Sunrise dealer and say, "I really want to use your company, but your bid is still out of my price range. If you could get the price down to (insert whatever dollar amount you feel comfortable with), I would be willing to sign today. Something like this, it usually works if they have any spaces on their books.
Bottom line, the Sunrise is the clear winner, their door bid seems a bit high but that might not be totally true -- another bid or two will tell you the answer.

4000 Series Review
I read where you say the WW 4000 Double Hung Series is a rebranded window made by a company called Xact. I have put these windows on two of my rentals in the New Orleans, LA area and so far 7 years ago on the oldest one I have been pleased. The windows have a half screen, low e, argon gas, foam wrap, double locks and grids with the accidental break warranty.
So far I have made claim on three of the windows for fogging and they mailed me a new right away without any trouble and it was easy to replace. They provide two invoices and on one it is handwritten that the model is a 3001 series and mezzo frame. On the other sheet completed by the sales guy it says 4000 series DH fusion weld 3001. To be honest these have worked fine for what I am looking for and I have no complaints so far.
I have other rental houses I plan to replace windows at and was wondering if it is in fact xact that still makes this model. I have installers but was looking to see if I could save some money by ordering direct from the company that makes them? The sales rep when I asked him for technical info referred me to aslide windows so I was curious if you knew for sue it was exact that still making the window or if it is now aslide and what is my best bet to deal directly with them in the future?
Mike - Homeowner - from 2016
[Site Editor Answers]
Window World has used windows from both of these companies and then relabeled them as their own. I'm not sure when you bought your windows or when they switched from Alside. To the best of my knowledge, Window World uses Comfort World windows, which are the relabeled Xact and Alside, so they use both. Frustrating, I know!
The distinguishing feature between these two windows is going to be the hardware and the lift rails. My suggestion would be to get a bid from Window World and make sure they bring a sample of the windows they currently sell. It should either match the hardware that you have or be different and this should tell you whether it's the Alside or the Xact, both of which are made by AMI.

4000 Series Reviews
What is your opinion between WW mid grade low E argon gas filled vinyl windows & Polaris Thermalweld low E argon gas filled vinyl ?
Bill - Homeowner - from 2016
[Site Editor's Answer]
Hi Bill, you've given me a fairly easy question here :) The Polaris ThermalWeld is a better window than anything Window World offers. Polaris is going to offer better craftsmanship and quality construction, while WW Comfort World series are simply not known for offering long term value to the consumer. I think most industry experts would agree with this assessment.

Window World 4000 Series Reviews
Hi Dane, I live in a town home complex in Dallas. I am getting quotes to have eight double hung windows replaced. I am trying to choose between the following:
Window World 4000 series at $5,228 all in.
Brennan NT Traditions at $7,481 all in. (NT Windows Reviews)
I have seen neighbors with each of the above windows. The traditions windows definitely feel much nicer on the inside and look nicer on the outside. But obviously the price is a big difference. Should I keep looking for a better quote on the traditions or would you go with Window World?
My neighbors that got the traditions windows from Brennan 3 years ago paid $700 a window and now I'm being voted $953. I get inflation and all but it just seems like a lot.
Quotes attached.
Thanks in advance for any advice you can provide.
Scotty - Homeowner - from 2023
[Site Editor's Answer]
Scotty, inflation has really driven prices up in the past few years and I know it's frustrating. I think I would ask some questions about WW.
Does your local WW get good online reviews?
What are they actually selling you as the 4000 series?
What is your timeline in the home?
The answer to these three questions should get us closer to the answer.
Yes, you should get a couple more bids in my opinion.

Window World 4000 Series Reviews
How would you rate the Window World 4000 Series? I got a quote from them on my 18 replacements that came out to $810 a piece but that including the window installation cost, capping on the outside, and trim stops. Does this seem like a good deal to you? Thanks - and I would love to get your list. Awesome website by the way for us nubes to windows/doors.
Jeff - Homeowner - from 2023
[Site Editor's Answer]
Jeff, I would rate the Window World 4000 a 5 out of 10. A very mid range range vinyl window. Fair price for what you're getting though. I would keep the bid and continue to collect more to see how that price quote compared to others.
