Kent's neighborhoods span East Hill's elevated homes, West Hill's established subdivisions, and the flatlands near downtown — a range of home ages and construction styles, many of them built without adequate wall insulation. RetroFoam is designed exactly for homes like these: existing walls, existing siding, and a homeowner who doesn't want to deal with a demo project just to get comfortable.

Why Kent Homeowners Choose RetroFoam
Cold winters, warm summers, and older homes make Kent a perfect fit for injection foam insulation.
Year-Round Comfort
Insulated walls don't just keep heat in during winter — they also slow heat gain in summer. Kent homeowners with air conditioning see benefits in both seasons after RetroFoam installation.
Reduced Heating Bills
Empty wall cavities are the single biggest source of heat loss in older homes. Filling them with RetroFoam stops that loss permanently. Most homeowners see measurable reductions in their first heating season.
One Day, No Mess
We work entirely from outside. Small access holes are drilled through your siding, foam is injected, and holes are patched. No drywall damage, no interior disruption, no cleanup required from you.
How It Works
Three steps. Done in a day.
1
Free quote. We inspect your siding, wall structure, and existing insulation levels. You get a complete estimate with rebate amounts before anything is scheduled.
2
Installation day. Small holes are drilled through siding between studs. RetroFoam is injected until each cavity is full, then holes are patched and matched to your siding color.
3
Lifetime warranty. RetroFoam is permanent and inert. It won't settle, sag, or degrade. Your installation is backed by a full lifetime material warranty.
$2.50/sq ft
