Taken on its own, crawl Space Drainage and Sump Pump Installation treats one part of the problem. Taken in order, it is the part that makes the rest hold. That is how we schedule it on Folly Beach jobs.
Water keeps coming back, so it needs somewhere to go rather than somewhere to sit.
Drainage and sump pump on lowcountry and coastal plain ground
Near Folly Beach 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.
In Folly Beach the complication is the water table. It sits close enough to the surface that soil under a house can be saturated with nothing broken, so this work is usually dealing with moisture arriving from below rather than from a failure inside the house.

Drainage and sump pump in Folly Beach: common questions
Does a sump pump need a backup here?
Worth considering if your Folly Beach crawl space takes water during storms, because storms are when the power fails — which is exactly when the pump is needed.
Where does the discharge go on a Folly Beach property?
Far enough from the foundation that the water does not track straight back in, to a point that is legal locally. Discharging beside the wall is the most common fault we find, and it is why some pumps run constantly.
Is crawl space water damage covered by insurance?
It depends on the cause, not the address. A burst pipe in a Folly Beach home is commonly covered; groundwater, long-term seepage and flooding usually are not, and flood damage generally needs separate cover. Photograph everything first.
Do you cover all of Folly Beach?
Yes — Folly Beach and the surrounding part of Charleston County, including the 29439 area. We also work in nearby James Island, Charleston and Kiawah Island.
How do I know whether it is groundwater or a leak?
That is the first thing we establish on a Folly Beach 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.
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.
