Foundation Repair FAQ for Charleston, SC

Short answers to common questions from Charleston area homeowners. Each answer stays inside what we can source, and anything about permits points you to your local office.

How do I know if my foundation has a problem?

Look for cracks that grow, doors that stick, floors that slope and gaps at walls. Any one can have another cause. An inspection shows which.

What causes foundation problems around Charleston?

Water is the usual suspect. Our soil survey samples show a water table at the surface at 67 of 233 points, and 87 points poorly or very poorly drained. Settling and fill add to it.

Is expansive clay a problem here?

Usually not. Shrink-swell is low at 213 of the 233 sampled points. The 12 high ones are in very wet, very frequently flooded soils.

Does every crack need repair?

No. Thin cracks that stay the same are common. Wide cracks, growing cracks and stair-step cracks in brick deserve a look.

How do I get a free estimate?

Who does the repair work?

Licensed and insured contractors we work with. Ask them any question about licensing, insurance and the written scope before you agree.

What should I do about a damp crawl space?

Find where the water comes from first. Gutters, grading and drains come before liners. See our crawl space page.

Can a sunken driveway or sidewalk be lifted?

Often, if the slab is in one piece. Foam injection raises it, and drainage keeps it from sinking again. Badly cracked slabs may need replacing.

Do I need a permit for foundation work?

It depends on the work and the address, and we cannot say for you. Ask the building office that covers your address. Our town pages list the offices.

Is my town on your list?

North Charleston, Mount Pleasant, Summerville, Goose Creek, Hanahan, Moncks Corner, James Island and Charleston itself.
