Tacoma has some of the most beautiful older homes in the Pacific Northwest — Stadium District Victorians, North End bungalows, Proctor Craftsmans. Most were built long before energy codes required wall insulation. RetroFoam is the minimal-disruption answer: we insulate through the siding in a single day, leaving everything inside untouched.

Why Tacoma Homes Need Wall Insulation
Tacoma's wet winters and older housing stock are a challenging combination.
Historic Homes, Modern Comfort
Tacoma's gorgeous older stock deserves to be livable year-round. Injection foam fills wall cavities completely without altering your home's historic character — no interior damage, no exterior changes beyond a small patched hole per stud bay.
Sound Dampening
RetroFoam's closed-cell foam matrix absorbs sound as well as heat. Homes near busy Tacoma streets and corridors notice a significant reduction in traffic and neighbor noise after installation.
Lower Heating Bills
Uninsulated walls are the single biggest source of heat loss in older homes. Once filled, RetroFoam prevents that loss permanently — most homeowners see a meaningful reduction in heating costs within the first winter.
How It Works
Simple, fast, no interior disruption.
1
Free in-home quote. We assess your walls, siding type, and any existing insulation. You receive a detailed quote with expected rebate amounts before anything starts.
2
One-day installation. Small access holes are drilled through your siding between studs. Foam is injected until each cavity is full, then holes are patched and color-matched.
3
Lifetime-warranted results. RetroFoam is inert, non-toxic, and won't settle or sag. Your walls stay insulated permanently.
