Everett's housing stock stretches from early 1900s craftsmans near downtown to mid-century homes in Silver Lake and Eastmont. Most of these homes were built without wall insulation — or with minimal fiberglass batts that have long since settled and lost effectiveness. RetroFoam injection foam is injected directly into the wall cavity through small access holes, filling everything completely and permanently.

Why Everett Homeowners Choose RetroFoam
The Pacific Northwest climate makes wall insulation especially valuable in Snohomish County.
Complete Cavity Fill
Unlike blown-in insulation that can settle over time and leave gaps, RetroFoam expands to fill every corner of the wall cavity — including around wires, pipes, and blocking. It stays put permanently without compacting.
Noise Reduction
Everett's active waterfront and busy corridors mean exterior noise is a daily reality for many homeowners. RetroFoam's foam matrix absorbs airborne sound, making rooms noticeably quieter after installation.
SnoPUD Rebates Help Offset Cost
Snohomish PUD electric customers qualify for $0.50 per square foot on wall insulation. Homes built before 1976 with no existing insulation may qualify for an additional $0.50/sq ft. We handle the rebate on your behalf.
