On a Dorchester 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 Dorchester 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 Dorchester 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.

Why it is worth dealing with now
Left alone, a wet Dorchester crawl space does not stabilise — it keeps feeding moisture into the floor structure until something upstairs gives.

Drainage and sump pump in Dorchester: common questions
Does a sump pump need a backup here?
Worth considering if your Dorchester 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 Dorchester 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.
What should I have ready when I call about my Dorchester home?
Your street in Dorchester, when you first noticed it, and what you can see or smell — standing water, a waterline on the piers, insulation hanging down, or a floor that has gone soft. Photographs help.
Do you cover all of Dorchester?
Yes — Dorchester and the surrounding part of Dorchester County, including the 29437 area. We also work in nearby Ridgeville, Harleyville and Saint George.
Does being close to the coast make this worse?
It raises the water table and lengthens the wet season, which is why homes near Huttos Lake and the low ground around Dorchester tend to need drainage as well as a barrier.
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.
