On a Aynor job, crawl Space Drainage and Sump Pump Installation follows from the inspection rather than preceding it — there is no point specifying this work before the source of the water is known.
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 Aynor 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.
Low ground and a long wet season change what this work has to withstand around Aynor. Homes near the Old Dead River in particular tend to need the drainage question answered as well, or the space simply returns to how it was.

Why it is worth dealing with now
A crawl space problem in Aynor is not self-limiting. The conditions that created it are still there, and they are still working.

Drainage and sump pump in Aynor: 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 Aynor, it cannot.
Where does the discharge go on a Aynor 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.
How quickly does water under a Aynor house need to come out?
Quickly. Wood starts absorbing moisture immediately and mold can establish on damp material within roughly 24 to 48 hours. In Horry County that window is shorter in summer than in winter, because the space stays warm and humid.
Why is my Aynor crawl space wet when nothing has leaked?
Near Aynor that is the normal pattern rather than the exception. At around 112 feet on the coastal plain, the water table sits close enough to the surface that soil under the house can be saturated with no pipe broken.
My house is near the Old Dead River. Does that change anything?
It can. Being close to the Old Dead River usually means a higher water table and a longer wet season under the floor, so drainage and a properly sealed barrier matter more here than they would further from it.
Does a sump pump need a backup?
Consider one if the space floods during storms, because storms are when power fails — which is exactly when the pump is needed. A battery backup or a water-powered secondary is worth discussing if your water arrives with the weather.
