What Missouri's Climate Means for Your Windows

Missouri has a humid subtropical climate with about 45 days above 90°F in summer and 100 days at or below freezing in winter, with average humidity around 70%. Windows here need to perform in both directions — blocking heat gain in summer and keeping heat in during winter. Double-pane glass with a low-E coating handles both reasonably well and is the standard recommendation for most Florissant homes. Older single-pane or failed double-pane windows are leaving money on the table in both seasons.

Why Hire a Local Window Contractor in Florissant

A window's energy rating only holds if it's installed correctly — gaps in flashing or sealant let in air and moisture regardless of the glass package. A licensed contractor in Missouri installs to manufacturer specs, meets local building code, and carries liability insurance. Always verify license and insurance before work begins.
