A failed vapor barrier, a poorly discharging sump line, or a vent placement issue are the usual culprits behind San Leandro, CA crawl space water problems.
We inspect the vapor barrier, sump discharge point, and vent placement to find the actual cause, not just remove the water.

Standard-height equipment simply doesn't fit most crawl space conditions, which is why we carry specialized gear.
