Great Falls sits in the South Carolina Upstate, on Piedmont clay. Clay does not absorb water so much as turn it away, which means heavy rain travels across the surface and arrives at the foundation rather than soaking in where it landed. A crawl space downhill of anything is a crawl space that takes water.
Clay also means slow drying. Once the framing in a Great Falls crawl space has taken on moisture, the surrounding ground gives it very little help in getting rid of it, which is why drying here is finished against a reading rather than a date.
Every job runs the same way: find the source before removing the water, dry to a moisture reading rather than a number of days, and put repairs in only once the space is dry. Skipping the first step is why crawl spaces get dried twice.
Signs worth acting on
These are the signs that bring people to us, in roughly the order they get noticed.
- A damp, earthy smell that is strongest in the lowest rooms
- A patch of floor that gives slightly when you walk over it
- Gaps opening at baseboards, or a door that no longer latches
- Condensation on ductwork or pipes under the floor
- Batts of insulation fallen away from the subfloor
- A silt line or watermark on the foundation piers

Great Falls crawl space questions
Why does my Great Falls crawl space stay wet for days after the rain stops?
Piedmont clay. Around Great Falls, at roughly 466 feet, the ground holds water against the foundation long after the surface looks dry.
My house is on a slope. Does that make it worse?
Usually. Water landing uphill of a Great Falls house travels along the clay to the foundation, so intercepting it uphill often does more than extra pump capacity underneath.
Is the damage sudden or gradual here?
Gradual, mostly. Around Great Falls it arrives in steps — a little with each storm — so by the time a floor feels soft upstairs the framing has usually been damp for a while.
How do I know whether it is groundwater or a leak?
That is the first thing we establish on a Great Falls 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.
