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.

Reliabilt 3500 Windows Cost

The Reliabilt 3500 window replacement costs should run $20 to $30 per square foot for the window itself. The 3500 series is comparable in quality to Pella 250 window costs and Simonton Asure windows prices.

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 that the window 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 window 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 window. All replacement window warranties include a number of exclusions and limitations that you should read in full prior to purchase.

Reliabilt 3500 Series vs. Simonton 6500 Window

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 windows seem relatively comparable to me and the price difference is substantial. What are your thoughts?

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 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 for home windows.
