We will tell you if crawl Space Drainage and Sump Pump Installation is not what your Greeleyville crawl space actually needs. Doing this stage out of order is the most common reason the work has to be repeated.
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 Greeleyville 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 Greeleyville 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 Greeleyville: common questions
Does a sump pump need a backup here?
Worth considering if your Greeleyville 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 Greeleyville 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.
Does storm flooding reach crawl spaces around Greeleyville?
Yes, and often with nothing visibly broken. After a tropical system the usual picture in Williamsburg County is a saturated crawl space where the water came up through the ground rather than out of a pipe.
Will my Greeleyville crawl space dry out if I open the vents?
Usually not. For much of the year the air around Greeleyville is warmer and wetter than the crawl space, so opening it up deposits moisture on the cool joists instead of carrying it away.
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 Greeleyville property changes that.
Where should the sump pump discharge to?
Far enough from the foundation that the water does not track straight back in, to an discharge point that is legal where you live. Discharging next to the wall is the most common fault we find, and it is why some systems run continuously.
