What we do in Johns Island
Crawlspace Cleanouts
Rural properties collect the most under the house. Construction scrap, animal nesting, and old insulation come out before anything else happens.
Learn moreVapor Barrier Installation
Older River Road homes often have no ground cover at all. A sealed barrier is the first real correction and usually the most cost effective one.
Learn moreCrawlspace Encapsulation
Where the water table sits high and readings stay stubborn, a sealed space with controlled air is the answer that lasts.
Learn moreInsulation Removal
Batts that have absorbed island humidity for years come down in pieces. We remove them, document the subfloor, and replace only after the moisture is handled.
Learn moreCrawl Space Dehumidifiers
Larger island footprints need a unit sized to the square footage, drained to daylight or a pump, not left to drip on the barrier.
Learn moreCL-100 Repairs
Island closings run into moisture findings regularly. We perform the CL-100 moisture corrections and hand your inspector clean documentation.

Why Johns Island crawlspaces stay wet
Much of the island is old farmland. The soil holds water, ditches carry it slowly, and lots sit flat enough that rain sits where it falls. Under a house, that means the ground stays damp far longer than it does a few miles inland.
Older homes along River Road and Maybank were built before ground cover was standard, so the soil is often bare. Newer subdivisions have plastic, but it is frequently thin, unsealed at the seams, and pulled loose by anyone who has crawled through since.
Drainage comes first here more than anywhere else we work. If water is entering, no barrier and no dehumidifier will hold. Once the water is handled, the rest is straightforward.
