We had STL Windows and Doors install a new patio door (where there used to be nothing but solid drywall) and a new kitchen window. The work that they did was fantastic! We LOVE how everything looks and STL Windows and Doors was so easy to work with. Their owner came out and explained everything to us and the whole team was incredibly friendly. We highly recommend this company and they will be the first company we call the next time we need a new door or windows. Cannot recommend them enough!

What a wonderful and professional company from start to finish! Ben gave us an accurate and fair estimate. He was extremely personable and explained our options for new windows and a new door. Hannah and Chad did the install and they did a phenomenal job! Hannah took the time to make sure each window was installed well and her caulking skills were amazing. Couldn’t recommend them enough to anyone who needs new windows or doors.

Why New Windows and Doors Benefit Ballwin Homeowners
According to Point2Homes, the median construction year for homes in Ballwin is 1976. That means a large share of the housing stock is pushing 50 years old. In many cases, the original windows and doors are still in place or were replaced only once with builder-grade products that have since worn out.
Ranch-style and new traditional homes dominate the Ballwin landscape, and many of them sit on generous lots with mature trees nearby. Those trees are beautiful, but the shade and moisture they bring can accelerate wood rot around window frames and door thresholds faster than homeowners expect.
Ballwin also has a strong culture of backyard living, and aging patio doors or sliding glass doors that don’t seal well work against that. Drafts, condensation between panes, and doors that stick or drag are all signs that it’s time for an upgrade.
With average home values in the $400,000 range, the investment in new windows and doors tends to pay off in comfort, curb appeal, and resale positioning.
