Ply Gem Premium Quality

Hi Tim, we replaced 9 windows in our previous house with CertainTeed with great results and were quite happy. With our new house (new for us, built in 2005) we are again looking to replace with high-efficiency windows. The new house is more complicated, much bigger, with large chalet style walls/windows (e.g. one wall has 6 lower windows, and 6 upper, angled windows).

Given that PlyGem replaced CertainTeed, we are looking at those for replacement options. However, in your review you said ‘Ply Gem windows aren't going to the best in the business’ and mentioned they were more for new-builds (though that was for the Contractor series). We want this to be a good purchase with high-end results as this would be a close to final house for us, and we live in a cold state.

Do you have any recommendations on other brands we should research? We live in Anchorage, Alaska.

[Site Editor's Answer]

Chris, I stand by the statement that Ply Gem aren't the best in the business, but they aren't bad by any means. Their Premium series is a good vinyl window and one that I would have in my own home. Ask about any upgrades that might be available, such as frame fills for increased rigidity, insulation and performance. Make sure that the installer of the Ply Gem windows has a good track record, online reviews and BBB standing.

As to other window brands in your area, I can't say that I know offhand. Google "milgard windows in anchorage alaksa" for instance and see if any dealers come up. Do this for Milgard, Anlin, Amerimax, Simonton, and Marvin. This should give you a pretty good idea of who sells in your area.

Certainteed Windows Warranty Claim

I have a Certainteed sliding patio door that is fogging up and leaking between the panes. Now that PlyGem is taking care of Warranties for Certaineed I cannot find anyone to help me. I have called 888-975-9436 three days in a row. They connect me to someone's voice mail to leave a message, but no one contacts me. How should I proceed?? I live in southern California. Thanks.

Michelle - Homeowner - from 2016

[Site Editor's Response]

Michelle, my advise would be to find a Ply Gem rep in your area or contact the company directly. You could always try to contact them through the website, but I think it's doubtful whether they will get back to you.

Unfortunately, these issues can be frustrating to deal with unless you have the contact info of whomever helped you originally.

I will post your issue online and hopefully you can find a local rep who can give you more specifics on the warranty claim.

Certainteed Window Reviews

I had Certainteeds installed about 4 years ago and we started having problems after only 3-4 months. They let so much cold in, I compared with a thermometer and the bathrooms where they were installed are about 3 degrees cooler than everywhere else. The inside sometimes gets a frost build up. The builder came out, reflashed all of the windows and added new insulation and there was no difference at all. When we finally got the dealer to send someone out, he said our body heat was causing moisture to build up and that made it frost inside. Really? We are so hot we're creating moisture in rooms we hardly even use? They're awful, just go with someone else.

CertainTeed Alliance Connection

A few years ago CertainTeed ended their licensing agreements with outside manufacturers. Some of them got together to form Alliance. CertainTeed has gone down in quality ever since. Alliance makes mediocre windows, but they are better than the new CertainTeeds. The Alliance Hawthorne and the CertainTeed Bryn Mawr III are pretty much the same window, but the Hawthorne is much better.

Vs Simonton And Sunrise

I'm trying to decide between the Simonton 5500, the Sunrise, or CertainTeed Bryn Mawr III. Sunrise has a great warranty and I like the finished look of them. They have clean welds and are probably the best window overall. Simonton has two lines (the Reflections and the Impressions) that I like and I'll probably end up with one of those. The price is good, and with a few upgrades they are about as good as the Sunrise. The Bryn Mawr looks good, but I've heard a lot about their quality control issues recently and they make me reluctant to buy anything from CertainTeed.

CertainTeed vs Harvey

I'm looking at Harveys and CertainTeeds for my house in Connecticut. Right now I have CertainTeeds from 2000 and 2003. We're putting on an addition so I need something that matches well. The old ones are good but I'm not sure if the company is still making the same quality window as before. I like my CertainTeeds, but is Harvey a better option?

Nancy - Homeowner in Connecticut - from 2010


Harvey makes a good window, I've never seen any real problems from them. CertainTeed is a lower end product. They have a lot of options to draw people in, but they are pretty poor in quality.

Certainteed Denali Garden Window

I'm looking at a CertainTeed Denali garden window. What does everyone think of them? I talked to a contractor who says he likes them, but I can't find a lot about them online.

Shawn - Homeowner - from 2010

[Contractor Response]

I would never use CertainTeed. They won't be around much longer. The name has been sold to a bunch of fly by night companies and you don't know who you're dealing with these days. Go with Simonton or Sunrise and you won't be sorry.

Certainteed vs BF Rich Or United

I'm looking for replacement windows in New Jersey. I have 4 casements, a double slider, a 9 foot patio door and 2 picture windows. I've got quotes for CertainTeed Bryn Mawrs, BF Rich, and Series 700 from United Window and Door. The quotes are all pretty similar, with pretty much the same warranties and features. I'm not sure which to go with. There doesn't seem to be a lot of info out there on United.

Nancy - Homeowner - from 2010

[Contractor Response]

A lot depends on the contractor. CertainTeed is now made by MI, and I'm not a fan. I don't know a lot about B F Rich. United is a middle of the road window, they aren't great but not horrible.

Carter - Contractor - from 2010

[2nd Response]

I used to use United windows a lot. They are mostly in New Jersey. They are a nice, solid product, that's what I put on my own house. I used CertainTeeds once because a customer insisted and I will never do it again.

John - Contractor - from 2010

Sold To Metal Industries

In 2009 Certainteed sold their window division to Metal Industries. They are awful now, they're poorly made and the service is bad too. The Simonton is much much better and I'd recommend it over a Certainteed any day.

Drafty Windows

After over 10 years as a builder you'd think I'd know windows. When I built my own home, I did a ton of research and ended up putting in CertainTeeds. I've never been so disappointed. They are so drafty that it almost feels like the windows are open. I called and called and they finally sent someone out. Their rep looked at them and said nothing was wrong with them. The warranty didn't matter - the cold drafty windows were apparently working the way they meant them to, which is a joke. It wasn't untli later that I learned they'd sold their window brand to someone else, so the name was the same but it isn't really CertainTeed anymore. Never ever would I buy them again or let anyone else I know get them either.

Good Customer Experience

We looked at three options when we got our windows. Pella from Lowes, Simonton or CertainTeed from Home Depot, all with a local installer. We liked the Simontons, but finally decided on MI Xacts, which are made by the same guys who make CertainTeeds. They are identical to the Bryn Mawr IIIs. The installation was great, plus the installer had worked with the windows before. He didn't cut corners and the whole thing was done neatly and carefully. He did the trimming and priming and some really nice caulking and touch up work. The windows all work really well and look great. Plus it only cost us $3600 for 9 windows.

Certainteed Bryn Mawr III Windows Reviews

The Bryn Mawr series looks dated and bulky. The Stylelines are awful, they don't have even sight lines. The Somerton is the best that they have, with a slim profile and a screen that pops in easily so you can wash the inside of the windows. They have a low u-factor, argon filled panes, a pretty modern and simple look that I like. I do like the Milgard with the one-touch lock, though.

Preston - Homeowner in California - from 2008

Certainteed vs Milgard Classic

I got two bids for replacement windows on my home here in SoCal. We have 60 windows, so I knew it would be high, but the Milgard Classic quote was for $32,000. The CertainTeed New Castle was under $23,000. Is there really that much difference in quality? The person I've talked to at CertainTeed is great, always answers the phone and is very helpful. The other salesman is awful, never returns calls. Customer service is important but I also want good windows.

Dale - Homeowner - from 2005

[Contractor Response]

It seems like a huge price to pay, but you really are getting $10k more window. You'll have a lot less air leakage, therefore lower energy bills and a more comfortable house. If you can afford it, you'll definitely be happier. They will last longer than the CertainTeeds and give you a lot less trouble. There are tons of dealers, so look around and find someone else to buy them from. The only reason to get CertainTeeds is if you know you're not going to be in the house more than a few years.

Scott - Contractor - from 2005

[2nd Response]

Milgard is better, hands down. If you don't like the dealer you can find another one, they are everywhere. I've had tons of trouble with CertainTeeds and they don't stand behind their product.
