Interstate Windows Prices
Interstate Window And Door Company is a Pennsylvania based company that sells their windows and doors through local dealers in many of the surrounding states. Generally, the company makes what I would consider to be a decent mid range product. Expect Interstate window prices to be $700 to $1000 installed.
Interstate Windows Prices
$700 to $1,000
Price Tier: 3 out of 5
(Installed Cost)
While they are not a top tier manufacturer, I still think the Interstate Window & Door Company is worth a look at the right price point. Ideally, pricing should fall in the $500 to $900 range per window fully installed. This would be for a medium sized unit and retrofit (or retrofit with some add'l work) installation.
👉 The best way to compare prices is to Getting 2 or 3 quotes and find quality local companies.

The 9800 series is the company's composite frame window. Generally, a solid buy at the right price point in my opinion.

Interstate Windows Prices | 6800 Series
The Interstate 6800 series is the company's mid range vinyl window. Generally, the 6800 is a good vinyl window if you don't plna to live in the home for 15 years or longer. If your timeline is longer than this, I would suggest you upgrade to a more substantial option.

6800 Vinyl Casement Quote
Tommy, we live in Northern Ohio and are looking at replacing half of our windows (half at a later date). 14 in all, but just 7 right now. All casements. We have three bids - what do you think?
Polaris Thermalweld Plus - $5,900
Interstate 6800 - $6,200
Alside Mezzo - $5,150
Jason - Homeowner - from 2026
Editor's Response
Jason, the best bid of the bunch is the Polaris Thermalweld Plus for $5,900. That's a much better value over the Interstate bid and well worth the increase in cost over the Alside Mezzo. That's the one I would pursue.
