Foundation Repair in the Charleston Area

Cracks, sticking doors and damp crawl spaces all have causes. In the Lowcountry, water is the first place to look.

Quick answerFoundation Pros of Charleston helps homeowners across the Charleston area with foundation, crawl space, slab and drainage problems. The work is performed by licensed and insured contractors. In our soil survey samples, wet ground is far more common than swelling clay. Start with a free estimate and an inspection, and we will point you toward the likely cause.

Water Is the Main Suspect Around Charleston

Foundation problems have causes, and around Charleston the cause is often water. We pulled soil survey data at 233 natural-soil points in seven towns. At 87 of them the soil is poorly or very poorly drained, and 67 show the water table at the surface at some point in the year.

Swelling clay is rare by comparison. Shrink-swell is low at 213 of the 233 points, and the 12 high ones are all in very wet, very frequently flooded soils.

So when a floor slopes or a wall cracks, water is the first thing to check. Footings, fill and the age of the house come next.

Storms, Tides and Older Buildings

The Lowcountry is humid and stormy. The National Weather Service counts 41 tropical cyclones that made landfall in its Charleston forecast area since 1851. Hurricane Matthew (2016) brought widespread rain of 6 to 12 inches.

Water also rises from below. NOAA's Charleston Harbor tide gauge shows sea level up about 1.4 inches every ten years.

Many homes here are older. Census estimates say about 48 in 100 homes in Charleston County were built before 1990.
