Interstate Replacement Windows

I am looking for replacement window and had a sales rep come by today, He has Interstate windows, both vinyl and composite. He made a very good sales pitch for this brand, with a lifetime guarantee. But this brand is not listed in the ones you reviewed, even though they have been in business since 1983. Do you know anything about this brand and would you recommend it?

[Site Editor's Answer]

Linda, I don't know a ton about Interstate windows. I looked on what I believe is their website and found some performance data that is actually pretty impressive. I don't think the composite and vinyl windows are going to be considered top tier like an Okna or Soft-Lite, but I think you'd be right to consider it a solid mid range performer.

I looked at a few website forums and saw that some consumers and installers had an issue with how the windows looked, specifically with the top rail and thickness of the window frame. So assuming you don't have an issue with the overall aesthetics, I don't see why you wouldn't at least consider them. Of course, I'd like to see you get a couple more bids and compare the windows on the performance data.

Interstate Windows Reviews

A lot of people think Interstate is a wood or wood composite window because it has a wood interior option. It's actually a cellular PVC composite. For the same material, Okna's Starmark is probably a better bet.
