About Clayton

Exterior Services for Clayton Homes

Clayton functions as St. Louis County's downtown — a dense urban village where historic 1920s and 1930s homes sit next to mid-century commercial buildings and modern infill condos. Single-family homes in Clayton's residential neighborhoods carry significant architectural pedigree, and homeowners replacing original wood windows must balance historic character with modern performance. We help Clayton homeowners navigate those choices with product knowledge and installation experience that protects their property's integrity.

The Window and Siding Source has served Clayton 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.
