Cayce homeowners don’t need a lecture about water — this Lexington County city sits directly on the Congaree floodplain, and anyone who was here in October 2015 remembers exactly what that means. But the flood was just the dramatic version of what happens under Cayce homes in slow motion every year: high groundwater, poorly draining red clay, and vented crawl spaces under the brick ranches that fill the neighborhoods between Knox Abbott Drive and the riverwalk. Attic and Crawl Space Solutions repairs and waterproofs those crawl spaces week in, week out.
What Does Living on the Congaree Floodplain Mean for Your Crawl Space?
It means the water table under your lot is high, and after heavy rain it gets higher — so moisture pushes up into the crawl space from below even when no water ever flows in through a vent. Hydrostatic pressure in saturated clay forces dampness through the soil year-round, and in the wettest weeks it produces genuine standing water under homes that have never “flooded” in the official sense.
That’s why so much of our Cayce work is drainage: French drains and sump pumps that give water a controlled way out, paired with sealed liners that keep ground moisture from evaporating up into your floor system. And when a storm does put real water under a house, our 24-hour emergency water removal team handles it — that service exists because of weeks like the one in 2015.
The 1950s–70s Ranch Problem
Cayce grew up as workforce housing — state employees, airport workers, mill families — and most of that growth happened between the 1950s and 1970s. Those solid brick ranches were built with foundation vents and, at best, a thin sheet of plastic on the dirt that disintegrated decades ago. After 50 to 70 Congaree-basin summers, the symptoms show up upstairs: cupping hardwoods, a musty smell after every rain, allergies that flare at home, and floors that bounce near the middle of the house.

Cayce Crawl Space FAQs
Water shows up under our house every time the river runs high. Can that actually be fixed?
Yes — recurring groundwater is managed with drainage, not wishful thinking. A French drain collects the water, a sump pump discharges it away from the foundation, and a sealed liner keeps what’s left in the soil from turning into humidity. We size the system to what your inspection readings show, not to a one-size package.
Do you offer emergency water removal in Cayce?
Yes — we run a 24-hour emergency water removal service, and Cayce is minutes inside our core service area. If a storm puts standing water under your home, call (803) 310-6330 and we’ll get it pumped out, then help you plan the permanent fix so the next storm is a non-event.
How much does crawl space waterproofing cost in Cayce?
A French drain and sump pump system typically runs $2,500–$6,500 in the Columbia area, and full encapsulation runs $4,500–$7,000 for most homes. Every crawl space is different — your free inspection includes an exact written quote before you commit to anything.
Our ranch was built in 1962 and the floors sag — is it too far gone?
Almost certainly not. Sagging floors in these ranches usually trace to moisture-weakened beams or soil-settled piers, both of which we correct — crawl space jacks run $500–$1,200 per jack, and damaged framing can be sistered or replaced. The inspection report shows you exactly which it is, with photos.
How quickly can you get to Cayce?
Fast — our crews are based in Lugoff and work the Columbia metro daily, so Cayce is a routine stop rather than a special trip. Free inspections are usually scheduled within days, and you’ll have the written quote right after.
