On a Sumter 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 midlands and sandhills ground
Around Sumter the water comes in bursts, so capacity matters less than interception and discharge. Getting roof water and surface runoff away from the foundation often removes most of the problem before a pump is specified at all.
Near Swan Lake and the lower ground around Sumter, this work usually has to account for both surface water in storms and soil moisture the rest of the year.

Why it is worth dealing with now
The cost of this work does not stay flat. Every season a Sumter crawl space stays wet moves more of the job from drying towards framing repair.

Drainage and sump pump in Sumter: 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 Sumter, it cannot.
Does a sump pump need a backup here?
Worth considering if your Sumter crawl space takes water during storms, because storms are when the power fails — which is exactly when the pump is needed.
Do you cover all of Sumter?
Yes — Sumter and the surrounding part of Sumter County, including the 29150 area. We also work in nearby Dalzell, Mayesville and Wedgefield.
Why is it dry in winter and wet by late summer?
Humidity rather than a failure. An enclosed space under a Sumter floor tracks the outside air, and by August that air has been wet for months.
Can grading and gutters fix it without a pump?
Sometimes, and it is worth checking first because exterior water is cheapest to deal with. Around Sumter, roof water and a slope feeding the foundation explain a lot of the calls we take.
Do I need drainage, or will a vapor barrier be enough?
A barrier handles soil moisture and vapor. If liquid water is entering the space — after rain, or as the water table rises — it needs drainage and a sump as well, because a barrier laid over water simply floats on it.
