Basement Waterproofing Near Me | Mount Pleasant, SC | Free Quote

Most South Carolina homes sit over a crawl space, and most crawl space problems here come down to one number. Summer humidity routinely runs past 85 percent in the Lowcountry and stays in the seventies even in the Upstate. Open vents let that air in, it hits cooler surfaces under the house, and it condenses. The vents that were supposed to dry the space are what soak it.

South Carolina Basement Waterproofing Pros has worked here since 2011. We do closed crawl space conversions, vapor barriers, drainage and sump systems, dehumidification, basement drain tile in the Upstate, crack repair, and grading and downspout corrections.

The state changes as you move across it.

Around Greenville and Spartanburg you get red clay and hills, and some homes have real basements. Through the Midlands it is crawl spaces on clay that drains slowly. In the Lowcountry the water table sits high and homes near Charleston deal with moisture from below and salt air from the side.

Most people find us by typing basement waterproofing near me into a phone in July, when the floors feel damp and the air conditioner cannot pull the humidity down.

A code-compliant closed crawl space here means a Class I vapor retarder over the ground, sealed vents, one of three approved ways to condition the space, ground graded to drain toward a sump or the perimeter, and a termite inspection gap of about three inches of bare wall left below the sill plate. That last one matters. This state ranks among the worst in the country for termite damage claims, with Formosan termites established along the coast. Cover that inspection strip with liner and you have hidden the exact place an inspector needs to look.

Here is something almost nobody mentions before selling you an encapsulation.

Test for radon first. The Upstate has granite-derived soils and the highest radon risk in the state, and sealing a crawl space can concentrate whatever is already coming up out of the ground. Adding a sub-membrane depressurization system while the liner is going in costs far less than retrofitting one after the fact. We ask about this on every Upstate job.
