Olympia and Thurston County are home to a wide range of housing ages — from historic Eastside homes to postwar ranches on Cooper Point. The region's damp, cold winters expose any gaps in wall insulation immediately. RetroFoam is designed specifically for these existing homes: it injects into the wall cavity through small holes in the siding, expanding to fill every gap and corner without any interior work.

Why Olympia Homeowners Choose RetroFoam
The Pacific Northwest's wettest capital city demands high-performance wall insulation.
Built for Wet Climates
RetroFoam doesn't absorb moisture. Unlike fiberglass batts that can hold water and lose R-value when damp, injection foam maintains its thermal performance even in Olympia's consistently wet winters.
Preserves Your Home's Interior
We work entirely from outside. No furniture to move, no drywall dust, no painting afterward. You stay home during installation and walk back into a clean house when we're done.
Non-Toxic Formula
RetroFoam is non-toxic, odorless, and safe for families and pets. There's no offgassing after installation. Once cured, the foam is completely inert and stable for the life of the home.
How It Works
Simple, fast, no interior disruption.

Installation day. Small holes are drilled through siding between studs. Foam is injected until the cavity is completely full, then holes are patched and matched to your siding color.
