Great Lakes Windows Prices

Great Lakes windows prices will vary from $350 for their Bayshore to $600 for the EcoSmart double hung installed. GLs are considered relatively expensive compared to their quality that they provide (although the prices listed below are good target prices that consumers should be happy with). Great Lakes is owned by Ply Gem, although they still sell windows under their own name. They discontinued their Grandview Series, although a very similar version is now sold as the Ply Gem Premium Series. Read reviews on Great Lakes.

Great Lakes Harbor View Series

Hi Tom, I am replacing 12 windows in Westchester County New York. I had multi quotes and a wide range of options. In the end I have decided on a Great Lakes harbor light window. Fully installed the price is $600 a window. This was not my cheapest option and it was not my best u-value but it is a reputable installer. The glass package I went with has a .30.

Having signed the contract today I am concerned I have made a mistake. Should I go back to the installer and discuss a new window before it is too late. For context, they originally wanted $650 per window.

Nick, the Great Lakes Harbor Light window is their more entry level window if I'm not mistaken. I like the fact that you got a reliable installer, but it does seem a bit high to me. I of course know nothing about the project details, but $600 to $650 a window should get you the high end vinyl window from Great Lakes I would think. Did you have him price out the eco-Smart or Comfort Smart windows series as well?

[Nick's Answer]

Thanks for the response. I did not have him price those windows but I did get a price on Sunrise. That was $700 a window and a little out of my budget. I asked if there was something in the $600 range. He offered Kensington at first and then Great Lakes after I said I was nervous about the Kensington ownership history (thanks to your site!).

My quotes were all over the place from various people. $400 for a Slocomb window from a less reputable installer, $900 for an Andersen wood replacement, $500 for a Pella, $600 for a Harvey, and then $600 for this Great Lakes.

I am not getting the best glass option or U-value I have seen, I am not having them put aluminum on the outside casing, they are doing a low pressure spray foam insulation, and they are giving me a great warranty in addition to the one from Great Lakes. The house currently has vinyl frames from the old windows so not new construction.

I think the higher price is due to me being 5 miles outside New York City. I also am paying for the reputation of this particular installer. I suppose I am not too concerned with entry level as long as I get a solid warranty and a good install. They windows look fine.

I appreciate your thoughts and, most importantly, I appreciate your site. I would've been lost without it. It truly was an asset and even if I don't end up getting the best deal I at least feel like a much more educated consumer.

Thanks again,

Nick, at the end of the day, Great Lakes makes a good window. Assuming proper installation, I think you should fare quite well. Best of luck in your upcoming project!

Bayshore Series

The Bayshore is their entry level window and from what we can tell uses the same basic design and frame as the upgraded windows from Great Lakes, but is essentially a stripped down version. It does not carry the same warranty terms such as transferability as their other series. The window has a U-factor of 0.47 and an SHGC of 0.48. Most homeowners should look at the Seabrook series or better to get the performance numbers and features that are going to provide them with long term value.

Seabrooke Series

The Seabrooke is their mid grade window that includes some nice upgrades and features from the Bayshore, including meeting rail fiberglass reinforcement that makes for a much sturdier frame. It comes as a bay, bow, casement, double hung, garden and slider. The window has a U-factor of 0.45 and an SHGC of 0.44. This window is fairly comparable to the Simonton 5500 (Platinum Series).

» Price Range


Lifestyles Series

The Lifestyles Series from Great Lakes is roughly equivalent to the Seabrooke series. The Lifestyles horizontal slider has a U-factor of 0.45 and an SHGC of 0.45.

UniFrame Series

The UniFrame is a decent window in its construction and design. It uses fusion welds that create a uniframe that most manufacturers now use. The EuroSlider in this series gets good marks for its versatility as a tilt in slider (also comes as a double hung, casement, bay or bow and garden window).The window has a U-factor of 0.42 and an SHGC of 0.39. This window is often sold at an "A" quality window price so homeowners should be sure that the price point on the window is appropriate.

» Price Range


EcoSmart Series

The EcoSmart Series is a composite window frame that is their high end energy efficient line (incidentally it is not listed on the Great Lakes site itself). It uses a one piece welded sloped sill, a non metallic space (I-Core), quality die cast aluminum hardware, quality seals and weatherstripping. Performance wise it is impressive, with a U-factor of 0.26 for the double hung (this drops to 0.15 with the ecoMaxKR glass upgrade) and an air infiltration rate of .06 (there seems to be some disagreement on this number, but this is what we found).
