About Florissant

Exterior Services for Florissant Homes

Florissant is the largest city in North St. Louis County, and its Cape Cods and ranches from the 1950s and 1960s represent one of the region's largest concentrations of aging housing stock in need of exterior upgrades. Aluminum siding that was once cutting-edge is now oxidizing and leaking air at every seam, while original aluminum windows generate condensation rings on cold mornings. Vinyl siding replacement and full window packages give Florissant homeowners an affordable, long-term solution for homes that have been waiting decades for attention.

The Window and Siding Source has served Florissant homeowners for over 24 years. We know the home styles, the weather patterns, and the specific challenges that come with owning a home in St. Louis County. Every estimate is free, every quote is written on-site, and every installation is completed by our own crew — not subcontractors.
