Paradigm 8300 Windows Reviews

The Paradigm 8300 series is the company's premium vinyl window. It comes standard with .75” insulated glass, a constant force balance, cam sweep sash locks, triple weather-stripping, a full screen, and injected foam insulation. Consumers can expect a U-factor of 0.28, SHGC of 0.31, VT of 0.47, CR of 61, and an R-value of 3.57. All in all, not bad numbers.

While I'm not a fan of the pocket sill design, which drains water through the frame and out the weep holes, this is a solid enough vinyl window.

Paradigm 8300 Series vs. Premium Atrium

Hello fellas, I was wondering if I could get some guidance on some replacement windows? I am looking into a high end Atrium double hung or Paradigm 8300 series or better. I live in Watertown, Ny (13601). Any help on quality or price would be greatly appreciated!

Travis - Homeowner - from 2018

[Site Editor's Answer]

Travis, hey there, so both the high end Atrium double hung and the Paradign 8300 series are solid mid range vinyl windows. Not world beaters by any means, but they are definitely decent windows. I would probably give the Paradigm 8300 the nod over anything Atrium makes. Not by a ton...

Two places you might look if you wanted to get something a bit better include Okna windows and Ideal windows. Ideal is out of New Jersey and their premium Majestic series. is often priced in the $500s installed (depends on the job of course but that's an average) and it has great performance data. It actually rivals some of the high end vinyl windows at more a mid range price.

There also might be a Soft-Lite dealer in your area and the Soft-Lite Bainbridge and/or Soft-Lite Classic is often a good window for the price. These would be my recommendations for your area.

Paradigm 8300 vs. Pella 200 Series

Hi Dane, wanted to get your opinion on the paradigm vinyl windows vs the Pella ones they sell at Lowes. Live in northern Maine where the winters are very cold, the window will be replacing the current window in our bathroom. The Paradigm are a little more expensive than the Pella but if they are that much better I'd spring for them.

Let me know what you think between the two.

Thanks for your help,

Amos - Homeowner - from 2018

[Site Editor's Answer]

Amos, if the question is between the Pella 200 series and paradigm, then I would have to go with the paradigm, although you didn’t tell me which model or series you were considering. Typically, Lowe’s carries a lower end window, which would lead me to believe that it’s one of the entry-level paradigm windows that you are looking at.

Their higher end 8300 series is a better window then the Pella 250. However, their lower end vinyl windows arent going to be as good as the Pella 250.

What I would do if I was you is ask all of the associates in windows at Lowe’s which window they go with for their own home. I’m not the biggest fan of the big box stores because they typically carry entry level windows from the different companies. However, I would say that the mid range paradigm in the Pella 250 series are roughly equal and I would consider them to be middle of the road vinyl windows.

Tim - Site Editor - from 2018

[Amos's Response]

Hi Dane, sorry for not including the model and series of the windows I'm looking at, the window from lowes is a thermastar by pella. and the other is the paradigm 8300 series from a local lumber and hardware store. The price difference is about 80 dollars. What would you recommendation between the two of these be?

Thanks again.

[Site Editor's Answer]

Amos, the Pella Thermostar is generally regarded as one of the worst vinyl windows on the market. The Paradigm 8300 model is definitely the way to go in this "match up." Best of luck to you in your upcoming project!

Paradigm 8300 Series vs RBA

Dane, Have a contract for 14 Renewal by Andersen Windows, the second size-lost originally $1700 installed, one a glider...after a lot of number mumbo jumbo, came out to about $1333 per window avg-seems pricy, but is the composite and the guarantee on the installation worth it?

They will also have to remove my exterior storm-screens. I have certainly seen how vinyl windows can fail here in Maine..we still have two days to cancel the contract, but I'm not sure if I can do better with an installer that is not part of the company. Any ideas?

Rebecca - Homeowner - from 2017

[Site Editor's Answer]

Rebecca, for $700 to $900 installed (depending on your installation requirements), you should be able to get the very best vinyl window on the market. A composite frame like the RBA is essentially made of vinyl and sawdust. The company touts it as some amazing technology, but the fact of that matter is that's what it's made out of. Top vinyl windows like the Okna 800, Sunrise Restorations, and Soft-Lite Elements blow the RBA composite window out of the water in terms of performance. If you want the best composite window on the market, go with the Okna Starmark, which is a bit bulky, but is an excellent window.

In terms of warranty, RBA does offer a good one, but it's no better than the three manufacturers I just mentioned. Typically, vinyl windows offer the best warranties in the business. I understand that Maine has very cold winters, but the top tier vinyl windows should handle it. I would suggest contacting each of these companies and asking them if they have reps who service your area.

RBA makes a nice looking window, but it's just not worth the price tag in my opinion.

Dane - Site Editor - from 2017

[Rebecca's Reply]

I couldn't find anyone who does Okna, and the recommended installer installs paradigm, not as high end ( unless 8300 is good enough). I will try to talk to these folks. Thank you.

Rebecca - Homeowner - from 2017

[Site Editor's Answer]

Rebecca, the 8300 Paradigm vinyl window is quite good. You are correct that it isn't quite as good as the Okna 800, but it does have some nice performance data with the LowE w/Argon & Foam Fill Frame/Sash. These are the upgrades I would go with (ask about a sash reinforcement as well). I would ask the installer how he thinks this window will fair in the cold maine winters, my guess is he won't have had any issues with it.

I would still search for a Soft-Lite, Sunrise, and Polaris rep just to see if any of these are available in Maine. Always good to get a bunch of estimates to see what's out there.

Paradigm 8300 Windows vs. Ply Gem Premium

Hello, we are currently getting approximately 15 double hung windows plus a picture window in our home here in Michigan. The company we are working with has several choices, however, we are making a huge investment and need help! ( unbiased!)

Ply Gem
Silver line by Anderson

I did some digging on silver line and am not satisfied with the quality and even how they handled customers. If you have any suggestions, would appreciate the input as we are at a deadline...

Thank you in advance!

Laurie - Homeowner - from 2017

[Site Editor's Answer]

Laurie, you are right to dismiss Silverline, their windows are basically junk. The Silverline 9500 series with a couple of upgrades is not bad though. However, you can and should do better. The Ply Gem Pro or Ply Gem Premium are both solid mid range vinyl windows. I like the Premium model over the Pro and it should be more than 10% to 20% more for the upgrade.

I would go with the upgraded Paradigm 8300 series I think as well. It has some nice components and decent numbers. I think with the upgraded glass package and good installation, you would be well served with this window. I like the upgrades of the 8300 series over the Paradigm 5000 series.

Bottom line is this -- both Ply Gem and Paradigm are known as solid mid range vinyl window manufacturers. If you go with their premium series, you are getting a mid-to-upper-end mid range vinyl window, which should serve you well.

One more solid mid range manufacturer in your state is Wallside windows. You may want to get a bid from them just to see how their price points compare to Ply Gem and Paradigm.

General Paradigm Windows Reviews

Paradigm Windows vs Harvey Slimline

Can you give me your thoughts on Harvey vinyl windows vs Paradigm? Doing a replacement of old windows and it would be helpful to hear your opinion. Thanks.

Marc- Homeowner - from 2017

[Site Editor's Answer]

Marc, Paradigm is a solid mid grade vinyl window that is probably on par with the Harvey Slimline or Classic. You really don't hear a lot about them, but I've seen the windows. Paradigm windows could use a bit of improvement on their welds and the overall look of it is nothing special. However, I've heard good things about their overall reputation and business practices. I would assume that the quotes are very similar in price. If it were me, I would turn my attention to the company doing the work itself. I would also use the two quotes to see which of the companies is willing to drop their price for the business. Here is a link to an article that talks about negotiating the bid price.

Dane - Site Editor - from 2017

[Marc's Answer]

Yes the quotes were very close. A difference of $200. The Harvey windows price has already been reduced to contractor price and would be installed by the company selling the windows. They can complete the job in 2 days. The Harvey window would be installed by a local contractor who is already doing renovations to the property and would take then 5-7 days. Trying to do as much research as I possibly can but after a while it gets confusing as to which is the best choice. Thanks for your response.

Marc- Homeowner - from 2017

[Site Editor's Answer]

Personally, I would go with the Harvey. It's a known brand and I like the idea that the same company that sells the windows is installing. If anything goes wrong, you know where to go. Harvey has a good reputation.

Dane - Site Editor - from 2017

[Marc's Answer]

Interestingly enough, after I responded to your reply I found an error in the Harvey quote. They are now $700 more than the Paradigm quote. Interesting process.

[Site Editor's Answer]

Hm, I would negotiate each bid and see where it comes in at -- or simply go to the Harvey dealer and tell him that his bid is $1000 more than the Paradigm. You are ready to go if he can match the other quote.

Paradigm Windows vs Simonton 5500

Looking to replace two patio sliding doors, I large picture window and one bow window. Looking at Simonton 5500 and Paradigm. Which window/door is better? Should I be looking at another company. I live in upstate New York and have a lot of snow and cold.

Terry - Homeowner - from 2016

[Site Editor's Answer]

Terry, the Simonton 5500 series is a good vinyl window. Paradigm is going to be lower on the food chain in my opinion, although I don't know a ton about them. My notion is that their premium vinyl window would be somewhere close to the Simonton 5500. You might want to get 1 or 2 additional bids.

You should be able to do a quick google search for local companies who carry the following brands; Okna, Sunrise, Soft-Lite, Harvey and Polaris. These are the better window manufacturers that should be available from someone in your zip code. Feel free to send me the bids and project details and I can give you an unbiased opinion on what might be the best bet from your home reno.

Dane - Site Editor - from 2016

[Terry's Answer]

Thanks for your quick reply. I have met with a Sunrise dealer/installer in my area for the 2 patio doors I need. He is quoting about 3,000 for each patio door and 3,360 for replacement picture window and 1 double hung on each side. both are installed price. I'm reading that Sunrise sash panels are welded, however the frame is "knock down" meaning it comes in pieces and assembled via fasteners.

I am unable to locate Okna or Polaris in my area. Still looking. Harvey is about 1 1/2 hours away from me. Looking into Soft-Lite.

Terry - Homeowner - from 2016

Paradigm vs Sunrise Windows

We are having new windows put in; a couple of very large casement windows and a new sliding patio door. (I would love french doors, but afraid we don't have enough room in the area that they would open into.) Our contractor gave us a few names, Simonton, Kolbe we are trying to keep price down, but I've seen horrible reviews on both. Any midline brands that you can suggest? Paradigm? I assume Sunrise is out of our league. I really appreciate any input. Its a big investment and I would hate to have them leaking in a year or two. By the way, we are in Michigan, if that helps at all.

Laura - Homeowner - from 2015

[Editor's Response]

Hi Laura, yes there are bad reviews on just about every company out there. Simonton has a pretty good reputation actually and Kolbe had some issues with wood rot a while ago and that never plays well with customers (and nor should it.) They are more of an aluminum clad wood window maker, not so much known for their vinyl windows. (More on Kolbe windows pricing.)

I would see if you can get bids from Sunrise, their standard or classic frame is quite nice and well made. Get a bid from Okna and see what you think of their prices. Polaris may be in your area, call up their national office and see if they have a rep in your area. The Ply Gem Pro is decent and the ProVia Aeris Series is good.

It never hurts to get some bids and see what price range you are talking about. If the initial price is high, see if you can slim down some of the bells and whistles like hardware to get the cost down into a place that makes sense for you.

Paradigm Window Review

I've installed a lot of different windows. I always like Harvey a lot, but then I just had a job putting in Paradigms and I think they're the best I've ever worked with. They come from the manufacturer packed really carefully and the arrive all cleaned (some windows have to be cleaned before you even install them). They are easier to install, so I can charge less to do it, and they have a smooth action and good seal.

Paradigm Vinyl Windows

Paradigm makes vinyl windows, and they are pretty much the same as all the others. Most people will probably be okay with them, nearly everyone in the northeast has comparable windows. They aren't anything special, I like fiberglass a lot better.

Kent - Contractor - from 2010

Mediocre Endrosement

I've recently put in some Paradigms, and I'm not normally a big vinyl fan but these are better than most. I personally like wood windows better, but were just fine.

Spike - Contractor - from 2010

Paradigm vs Okna & Sunrise

The Paradigm is ok if you're looking for a builder's grade window. It isn't the same level as an Okna or Sunrise. You can get better without paying a lot more.

Tim - Contractor - from 2009

Paradigm vs Jeld Wen Windows

My house is 13 years old and the windows are starting to rot. I'm looking mainly at Jeld-Wen, which uses a stainless steel spacer (Paradigm uses a duralite). Which is better? Also, the contractor I talked to said a full frame replacement isn't necessary, but if they've started rotting this early I don't trust the frames.

Anders - Homeowner - from 2009

[Contractor Response]

Paradigm is a good choice, I know a lot of contractors who won't work with anything except Andersen and Marvin for their higher end clients and Paradigms for your average home.

Peter - Contractor - from 2009

Paradigm Customer Endorsement

I've installed tons of Paradigm windows, and I think they're a great company. The install is easy, so it's hard to have problems, and my customers have all been happy with the windows. A couple of times when we did have a minor issue, they really bent over backwards to make it right. They have a lot of different options available and the window itself is really well designed so they only need minimal weatherstripping, not thick bands like I've seen on some cheap ones.
