Alliance Windows Reviews

Explore Alliance Windows reviews, prices, and company information on their Windgate, Belmont, and Hawthorne window series. The company is actually called Alliance Window Systems and their structure is very different from other window manufacturers. They are comprised of smaller manufacturers located in different regions of the eastern half of the U.S.

Collectively, they can buy better parts and components by combining their efforts. Then they manufacture the windows in their own factories. It's almost like a union to get better buying power. The windows are then sold by these smaller manufacturers under their own brands or names. (Midway Windows is one example of the Alliance network.)

Bottom Line: Some of the Alliance Windows get good reviews, while others get more mixed reviews. The company makes three main vinyl window series: the entry level Belmont, the mid range Windgate, and the premium Hawthorne series. I would say the Windgate is a mid range vinyl window, while the Hawthorne is a good mid range vinyl window.

I'd give Alliance Windows a 4.2 out of 5 star rating based on 3 reviews posted at the bottom of the page.

Alliance Windows Warranty Information

Alliance Windows offers a warranty called the Assurance Plan. For most homeowners, this includes five years on labor and a limited lifetime warranty on the frame, components, and sash. This warranty is transferable for up to 20 years from the install date of the install. All said and done, this is a very strong warranty when compared with others in the window and door industry.

Alliance Belmont vs Soft-Lite Barrington

John, thank you for your website! I'm in the St. Louis area and looking to replace 8 windows with a mid range vinyl. I plan to live in the house for at least 5 years but probably not more than 15 years. I've received at least 8 quotes so far and it looks like I've narrowed it down to the Alliance Belmont series, the Soft-Lite Barrington (they originally quoted me a higher series) and the Window World option based on price. All the exterior contractors want to quote the Alliance Belmont (I have 3 of these quotes) and the window only companies have drastic price differences.

I've tossed out the $1000 plus / window options. Plus I had a really bad experience with Universal Windows Direct as after getting their 4th offer down to $800 per window they told me the quote was invalid because the saleperson didn't factor in tempered glass for 2 of the windows. At that point I had them higher than Alliance Belmont and Window World in terms of quality.

Also, I can't find anyone in the area for an Okna windows cost quote, but I'm guessing they will want a pretty penny for that like the gent trying that quoted me the Provia windows. Also, I'm a frugal buyer that likes to research (analysis paralysis) and trying to get the most bang for my buck. I'm by no means an expert but I can make sense of the U-factor, SHGC and spacer material, etc.

I'm trying to stay around $775-$800/window installed for the best mid-range window I can get. I'm half tempted to spend a little more to get the better Soft-lite window but I can't convince myself to pay $950/window. Between reading your website and the information I've gathered from the quote I'm going to guess that you would recommend the Soft-Lite Barrington out of these 3 but would welcome any further discussion. Any feedback or suggestions would be greatly appreciated.

John, yes I would say the Soft-Lite Barrington is the better bet over the Alliance Belmont and the Window World. Although Window World has recently been installing Simonton windows, which are pretty good. Have you tried Zen Windows? They (often) sell a Soft-Lite Classic as their Nirvana or mid range vinyl window and it's a nice step up from the Barrington with a .07 air infiltration rate. Quite a nice window and I have been pretty impressed with their price points (not always of course).

The Okna 500 is a fantastic window, but it probably would be in that higher price range based on the bids you are getting right now. Might be worth a bid, but it sounds like you've been through the ringer with bids already.

Thanks John for the feedback. Yes, the quote I have for the Soft-Lite classic / Nirvana is actually from Zen Windows. They quoted me $150 less per window to go with their Barrington equivalent model. The additional caveat is that the warranty for this Barrington window does not cover glass breakage and costs me $150 per visit.

I tried to negotiate down the Nirvana window but I was only able to get $30 off per window so the Nirvana is costing me roughly $930 / window. If this was the forever home it would be a no brainer but I’m too frugal to give the extra $1200 needed. What’s weird is the specs for u factor and shgc and air filtration for the Alliance Belmont are .27, .28 and .12 versus the Soft-Lite at .29, .28 and .07.

Also, I thought the duralite spacer to be better than stainless steel. Further, I do notice the features on the Custom-lite to be better. The Window World was series 4000. So I’m not sure if they are Simonton. I double checked and Okna is not available in my area.

Bennie, that is an amazing price difference in quotes! The Okna 500 is probably the best long term value in there. The Alliance Hawthorne would probably be my pick if you are staying in the home for 10 years or less.
