Control moisture
Holds crawl RH at the right target (typically 50%) so soil moisture and outside humidity stop riding upstairs.
Holds crawl RH at the right target (typically 50%) so soil moisture and outside humidity stop riding upstairs.
Stops the moisture cycle that ages joists, rusts ductwork, and feeds mold-supporting conditions in the crawl envelope.
MERV-rated filter + air movement pulls dust and biological particulates out of crawl air before stack effect lifts them upstairs.
HumidiGuard pulls moisture out of the crawl space, filters the air, and moves it gently so the whole envelope stays at the relative humidity it should be. The dehumidifier finishes the encapsulation system — without it, the vapor barrier is half the fix.

The musty smell is gone. Crawl is sealed, HumidiGuard running quietly, RH at 48% all summer. House upstairs feels completely different.
They walked the crawl with me before quoting — first contractor that explained why a vapor barrier alone wasn't enough. Adding the dehumidifier was the difference.
Honest crew, written quote, written warranty. Free HumidiGuard was the kicker that decided it for us — paid for itself in the first dry summer.
