Common questions about crawl space conditioning
A conditioned crawl space is one that's sealed off from outside air and moisture and brought inside the home's thermal envelope — typically by foaming the walls and rim joists with closed-cell foam, sealing the vents, and adding a ground vapor barrier. The result is a dry, clean, insulated space that improves air quality and comfort in the home above and eliminates the moisture problems vented crawl spaces cause.
In almost every case, yes — musty crawl-space odors come from moisture and the mold it grows. Closed-cell foam seals out the moisture and humidity at the source, and conditioning the space eliminates the damp environment mold needs. If there's existing mold or water intrusion, we'll identify it during the walkthrough and address it as part of the scope.
