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 Mc Coll jobs.
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 Mc Coll 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.
Midlands ground drains unevenly. Sand moves water quickly until it meets something that does not, and it then travels sideways — which is why exterior grading gets looked at on Mc Coll jobs alongside the crawl space.

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

Drainage and sump pump in Mc Coll: 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 Mc Coll, it cannot.
Where does the discharge go on a Mc Coll 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 Mc Coll home?
Your street in Mc Coll, 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 work outside Mc Coll itself?
Yes. We cover Marlboro County broadly, including Tatum, Clio and Bennettsville, and the rest of the Midlands and Sandhills of South Carolina.
Why is it dry in winter and wet by late summer?
Humidity rather than a failure. An enclosed space under a Mc Coll floor tracks the outside air, and by August that air has been wet for months.
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.
