About Sunset Hills

Exterior Services for Sunset Hills Homes

Sunset Hills is a small, affluent community where long-established ranch homes sit alongside newer custom properties — and the gap in energy performance between old and new construction is measurable. Original large picture windows and sliding glass doors on the 1960s ranches are single- or early-double-pane glass with no low-E coating, generating hot spots in summer and cold zones in winter. ProVia replacement windows with triple-pane options give Sunset Hills homeowners modern thermal comfort in homes built for an earlier era.

The Window and Siding Source has served Sunset Hills 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.
