Humid, salty air moves under the house through every vent, and sandy lots let the ground stay damp beneath it. We inspect, take moisture readings, and correct the conditions at the source.

Learn more https://intercoastalcrawlspace.com/services/crawlspace-cleanout ### Vapor Barrier Installation A sealed, overlapped ground cover stops moisture rising from the sand beneath raised island homes. Learn more https://intercoastalcrawlspace.com/services/vapor-barrier-installation ### Crawlspace Encapsulation Where ocean air keeps readings high all summer, sealing the space and controlling the air holds it steady.

We remove them and photograph the framing underneath.

We correct them and document the work for re-inspection. Learn more https://intercoastalcrawlspace.com/cl-100-repairs Local conditions ## Why island air reaches the floor framing Isle of Palms sits between the Atlantic and the Intracoastal Waterway, so the air under the house carries moisture most of the year. Vented crawlspaces pull that air in, and it condenses on cooler framing and ductwork. Sandy soil drains fast on top but stays damp a short way down, and many lots sit low. Without a sealed ground cover, that moisture keeps rising into the space even when the yard looks dry. We take readings on the joists, sills, and subfloor, photograph what we find, and recommend only the work those readings support.
