This company was completely professional and did a great job! We had a big project that took 5 days and after each day they cleaned up and you couldn't even tell they were here. I've had windows replaced in other homes before and I've always been picky about the trim work – the trim work STL Window and Door did was outstanding and actually looks better now than it did with the original windows. I can't recommend STL Window and Door enough, really satisfied with the purchase!

Why New Windows and Doors Benefit Des Peres Homeowners
Des Peres is an established, high-value community where homeowners take genuine pride in how their properties look and perform. According to Point2Homes, the median construction year for homes here is 1976, which means a large portion of the housing stock is now 50 years old or more. Original wooden frames and single pane glass from that era were never designed to handle today’s energy costs or comfort expectations. Replacing them with modern, insulated windows can make a noticeable difference in both your monthly bills and your indoor comfort year-round.
Curb appeal also carries real weight in Des Peres. Homes here move fast and sell at a premium, with median home values well above the St. Louis County average according to Zillow. A worn entry door or fogged-up window can drag down a home’s first impression significantly. The Zonda 2025 Cost vs. Value Report shows that steel door replacement can recoup up to 216 percent of its cost, making it one of the smartest upgrades you can make before listing or simply to protect your investment long term.
