Reliabilt 3500 Windows Reviews
The Reliabilt 3500 window is the high end vinyl window from Reliabilt that is actually a relabeled Atrium 8700 series. Reliabilt windows are often sold through the big box stores such as Lowes and Home Depot and the per window cost can seem very low. However, be sure to note that typically the windows listed on these particular sites have no upgrades or add ons that can help with the overall performance of the window (and add to the cost of the window.) It's similar to the MSRP on a car - essentially the base price.
The Reliabilt 3500 series includes all of the upgrades of the Reliabilt 3301 window, along with a better warranty, aluminum sash reinforcement and one extra color option in bronze. This reinforced sash should improve the performance of the window. Standard features on the 3500 include a beveled exterior, push button night vents, a constant force balance system, and an aluminum charcoal mesh half screen. The Reliabilt 3500 Window Series gets a out of 5 star rating.

Reliabilt 3500 Series Windows Cost
The Reliabilt 3500 series should run $350 to $600 fully installed. Factors that will determine whether you pay at the top or the bottom of that price range include things like the size of the window, the type of installation required, the upgrades that you opt for, and the company that you select to install the unit. The 3500 series is comparable in quality to Pella 250 window costs and Simonton Asure windows prices.
-- Window Itself: $200 to $350 per square foot --
-- Standard Installation: $150 to $250 per opening --
-- Fully Installed: $350 to $600 --
Reliabilt 3500 Ratings
The Reliabilt 3500 double hung should have a 0.31 U-factor, 0.21 SHGC and a design pressure rating of 35. Several upgrades can get the DP rating up to 50 to make the window coastal zone compliant.
The Reliabilt 3500 model spec sheet says it is Energy Star qualified in all 4 zones. Consumers should double check this with their contractor prior to purchase.

Reliabilt 3500 Warranty
The 3500 series comes with a limited lifetime warranty that covers the vinyl mainframe and sash. The 3500 Series also includes a 25 year glass breakage provision, although on a prorated basis. The warranty is transferrable to a subsequent owner - however the warranty period for the second owner is only 10 years from the purchase date of purchase.
In general, this warranty is relatively solid based on the price point of the unit. Most replacement warranties include a number of exclusions and limitations that you should read in full prior to purchase.

ReliaBilt 3500 Windows Reviews
Hi John, weve had 5 visits and getting really lost in the differences and also can't find good exterior pics to see the various profiles in real time. The samples are so small hard to picture.
We are replacing 3 sliders and 22 windows. 5 of those are fixed frames in San Antonio TX. Prefer more window than trimming but not to sacrifice energy efficiency/sound/insulation. Focused on value for $ vs cheapest. White / white.
We've narrowed down to:
Home Depot Simonton 6100 Cost: $27K
Lowes: Relia built 3500 by Atrium : $30K
M&M (local) offers Simonton 5050 and windcore 5400. No total bids yet but material for Simonton was about 17K. Wincore about 14k.
Also had Window World 4000 but think we've ruled it out... was for 26k.
Insight please? Who else/what else would you recommend? We need to rule Hime Depot in ir out by Tuesday for their really good financing terms... 0% 24mths.
Thanks!

Laurua, the Wincore 5400 series is a pretty decent option and at $14K, is a heck of a lot better than any of those prices from HD or Lowes. M&M Windows gets great reviews so that makes me feel great about the decision. But I would prefer the Wincore 7700 or the Simonton 5500 or Impressions 9800 series over the entry level windows they are offering right now. Can you go back and ask them if they offer other window options?

How Much Do Reliabilt 3500 Cost
To summarize, Lowe's is quoting 12 windows in total. 11 - 2 wide sliders and 1 - 3 wide.
Brand: Reliabuilt
Series : 3500
Install type: pocket
Features: energy star rated
Total: $9,576.00
My personal opinion is that this quote is high for a mid level vinyl option in the 44146 area code. Interested in getting your opinion.

Richard, I agree that's too steep for the 3500 with pocket replacement. Lowe's pricing has been as bad as everyone elses has lately.

Reliabilt 3500 Series Reviews
I live in Central Virginia and received quotes from Home Depot for the Simonton 6500 ($10,000) and from Lowes on the Reliabilt 3500 ($5200 or $6400 for the 3900). Both of these seem relatively comparable to me and the price difference is substantial. What are your thoughts?
Scott - Homeowner - February, 2018
Website Editor's Answer
Scott, that is a big difference in price. I have to be honest though, I don't love the Reliabilt 3500 -- the 3900 is the better window...but far from great. The Simonton 6500 series is the better window than either of the Reliabilt models, but not worth the difference in price.
Have you tried to get some quotes from local companies? You may be able to get a better vinyl window for a price in between the two. Check our recommended brands and see if any local companies sell in your areas.
Feel free to send the bids to me and I'll give you my two cents. 7, 8 years down the road you may start having some issues with the Reliabilts and may end up paying more in the long run to replace them
