St. Louis weather can destroy products that in other markets will last for decades. Our freeze/thaw, high humidity and wide temperature swings will really put any product to the test. We only use doors and windows we know will withstand our St. Louis area’s frequent freeze/thaw environment and will provide many years of no maintenance. Installation is just as important has the products. We offer Provia Doors and Anderson Windows products, so you know whenever you’re working with Siding Express, you’re only getting the best.
