Penny Window has been St. Louis's most trusted name in window replacement since 1953: family-owned, with our own in-house installers. We're the local specialist for replacement windows, window installation, and energy-efficient windows and doors across the St. Louis metro and St. Charles County. Among door companies in St. Louis, few install with their own W-2 crews like ours: all Andersen-certified, lead-safe, and seasoned with 10 to 20 years on the job. Every window replacement and new door is built for St. Louis weather and backed by a 20-year product warranty plus a 1-year installation warranty. Choose a premium Andersen Fibrex line or a competitively priced value window, then book your honest, no-pressure free estimate today.
