STL Windows Direct is a division of STL Design and Build. When we remodel kitchens, bathrooms and basements, window and door replacement is often part of the project. STL Windows Direct was born because we realized our customers wanted premium quality in an affordable window. In response, we created a better, more energy-efficient, longer-lasting window that is designed specifically for the St. Louis weather. Our exclusive windows are at a competitive price point and still offer a lifetime warranty and transferable warranty!
