A crawl space problem usually announces itself indirectly — a musty smell upstairs, a spike in humidity, or a home inspection that turns up standing water no one knew was there.
We inspect the vapor barrier, sump discharge point, and vent placement to find the actual cause, not just remove the water.

Confined-space equipment lets us extract water from every corner of a Alviso, CA crawl space, not just the accessible middle.
