Is This Your Problem?
Musty smells, damp walls, condensation, and mold spots in your Lakewood basement — even with a dehumidifier running. Why it happens Moisture migrates up through the slab and in through the foundation walls, and the rim joist — where the foundation meets the floor joists — is a major cold-air and moisture entry point. The fix Closed-cell spray foam on the rim joists and basement walls creates a vapor barrier and moisture seal. It stops cold air infiltration at the foundation and blocks the humidity that feeds mold. What it costs Rim joist sealing typically runs $300–$600; full basement walls run $1.50–$3.50 per square foot. It's the highest-leverage fix before finishing a basement.
