Drainage and sump pump on lowcountry and coastal plain ground
Near Isle Of Palms a sump is often working against a standing water level rather than an occasional event, and close to the coast that level can be tidally influenced. The system has to be sized for water that keeps arriving, and the discharge has to go far enough that it does not simply return.
Flood-zone construction around Isle Of Palms is built elevated, which means newer homes have crawl spaces too. Newer framing, the same conditions underneath.

Drainage and sump pump in Isle Of Palms: common questions
Can grading fix it without installing a pump?
Sometimes, and it is checked first because exterior water is the cheapest to deal with. Where the water table itself rises into the space, as it can around Isle Of Palms, it cannot.
Does a sump pump need a backup here?
Worth considering if your Isle Of Palms crawl space takes water during storms, because storms are when the power fails — which is exactly when the pump is needed.
Can I stay in the house while the work is done?
In almost all cases, yes. The work happens under the floor, and access is usually through an exterior hatch. We will tell you up front if anything about your Isle Of Palms property changes that.
How do I know whether it is groundwater or a leak?
That is the first thing we establish on a Isle Of Palms call, because everything after it depends on the answer. A supply line, a drain, water rising through the soil and runoff coming in through the vents each leave different evidence.
Do you work outside Isle Of Palms itself?
Yes. We cover Charleston County broadly, including Sullivans Island, Mount Pleasant and Charleston, and the rest of the Lowcountry and coastal plain of South Carolina.
Can grading and gutters fix it without a sump?
Sometimes, and it is always worth checking first, because exterior water is the cheapest to deal with. Where the problem is surface runoff from a roof or a slope, fixing discharge and grade can be enough. Where the water table itself rises into the space, it cannot.
