Great Lakes UniFrame Windows Reviews

The Great Lakes Uniframe is considered a well made and designed window. The UniFrame uses a fusion weld design to create a single uniframe that is now standard in the industry. It is available in a number of different styles such as a double hung, garden and casement, but the tilt in slider is a stand out for its design and versatility.

Standard features include narrow sightlines, flush mounted sash locks, a sloped sill, a fiberglass reinforced sash rail, two sash cam locks, and ventilation limit locks. In addition, the Uniframe window comes with polyurethane filled vinyl chambers, tilt in sashes on the hung windows, and a block and tackle balancing system. All in all, the window offers some very nice features.

It can be ordered as a double hung, casement, bay, bow, slider, garden or as a sliding patio door. Color wise, the window comes in a number of interior woodgrain's as well as a camel and creamy white. The window can be ordered with the exterior colors of sandstone, camel, creamy white, dark bronze and earthtone.

Some installers have opined that the UniFrame is sold at a premium price that does not quite match up with the quality of the window. However, in terms of quality, the Uniframe delivers very solid performance and durability, so assuming a good price point, this is a good vinyl replacement option.
The Great Lakes UniFrame Window Series gets a 4.4 out of 5 star rating.

Uniframe Windows Complaint

Tim, we have six uniframe windows installed by Window X-perts in Wausau Wi they no longer answer their phone. There is a problem with a smaller awning style window, there is condensation between the panes of glass. With the installer gone how do I get this repaired?

Tim, I would call a Uniframe dealer like this one -- -- and see if they can point you to the right person who sells the Uniframe in your zip code. Don't tell them you have an issue, tell them you are looking for a quote on windows. Assuming they give you the local dealer for your area, have them come out to give you a quote on windows. When they come out, ask about the warranty on the Uniframe. When they tell you it is a lifetime warranty, then you let them know you have their window and are having an issue. It's like a lawyer's trick that still might work, but it sure as hell should right?!?!?

Try this first and see if it works!

Uniframe Replacement Windows

My wife and I purchased a home that has Uniframe Replacement Windows.

The Sellers were an older couple and they could not remember the exact date they were installed (it was likely in 2011 or 2012). They also could not remember the company that installed the windows.

We have two windows in which the seal has failed and would like to determine if these would be covered under the Lifetime Warranty. We are in Kansas.

Website Editor's Answer

Kris, the Uniframe is probably a Great Lakes window so my suggestion would be to find a Great Lakes Uniframe deal in your area and see if they were the ones who installed it.

You may want to be a little cagey at first, i.e. perhaps pretend that you are looking for some more of the windows instead of want to get warranty relief. I only say that because some of these dealers want to avoid warranty issues and they may not provide you with the info you are looking for if they think you are there to get relief. Sad but sometimes true.

I would obviously start by contacting ABC New Dimension Products. If you can't get ahold of them, I would call up Great Lakes windows and see if you can talk with someone in their customer service department to find out how to start a warranty claim.

Crystal, the Uniframe with the h2 upgrade should deliver a .27 U-factor, .25 SHGC, 42 CR, and a .42 VT. The local rep who is selling the window ought to have this information at his fingertips so I would suggest double checking this with him.
