We will tell you if crawl Space Drainage and Sump Pump Installation is not what your Union 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 piedmont and upstate ground
On Union slopes the water arrives sideways. Interception uphill — a collection line catching it before it surfaces — usually does more than a bigger pump dealing with water that has already reached the crawl space.
Around Union the damage tends to accumulate in steps, a little with each storm, rather than arriving all at once. By the time it is noticed upstairs it has usually been building for a while.

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

Drainage and sump pump in Union: common questions
Does a sump pump need a backup here?
Worth considering if your Union crawl space takes water during storms, because storms are when the power fails — which is exactly when the pump is needed.
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 Union, it cannot.
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 Union property changes that.
How do I know whether it is groundwater or a leak?
That is the first thing we establish on a Union call, because everything after it depends on the answer. A supply line, a drain, water rising through the soil and runoff coming in through the vents each leave different evidence.
Do you work outside Union itself?
Yes. We cover Union County broadly, including Buffalo, Jonesville and Lockhart, and the rest of the Piedmont and Upstate of South Carolina.
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.
