Local conditions

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.
