Between Lake Quail Valley and the lower ground around Irmo, crawl spaces in this part of Richland County tend to be dealing with a mix: surface water in storms, and soil moisture evaporating up into the space the rest of the year.
That mix is why we look outside as well as under the house in Irmo: grading, downspouts and where the roof water lands often explain more than anything visible in the crawl space itself.
What we will not do is pump a Irmo crawl space out and leave. If the water is going to come back, the drainage and the barrier are the job, not an upsell after it.
Signs worth acting on
You do not need all of these. One is enough.
- Air in the house that smells of damp soil, especially in summer
- Springy or sloping floors over part of the house
- Hardwood boards lifting at the edges or pulling apart
- Visible water, mud or standing damp under the floor
- Rusty fixings, or dark staining on the joists
- Windows and doors that stick in humid weather

Irmo crawl space questions
Why does my Irmo crawl space only flood after heavy rain?
That points to surface water rather than groundwater. Storms around Richland County deliver a lot of water quickly, and when the ground cannot take it fast enough it travels across the surface and in through the foundation vents.
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 Irmo, roof water and a slope feeding the foundation explain a lot of the calls we take.
Why is it dry in winter and wet by late summer?
Humidity rather than a failure. An enclosed space under a Irmo floor tracks the outside air, and by August that air has been wet for months.
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 Irmo property changes that.
How do I know whether it is groundwater or a leak?
That is the first thing we establish on a Irmo 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.
