Family owned and fixing DeKalb foundations since 1979. Free inspection, written warranty, and our own crews on every job.
DeKalb sits on the heavy clay soils common across DeKalb County. That clay swells when it rains and shrinks in dry spells, and the constant movement is hard on foundations.
Add Chicago freeze-thaw winters and older basements built decades ago, and you get the cracks, settlement, and seepage we see across town every week. We have repaired these homes for over 45 years.
We seal and stabilise cracks at the source, so they do not come back.

"Two companies wanted to rebuild the whole wall. Perma-Seal stabilised it with carbon fibre in a day, half the price."
"No pressure at the inspection. They found the root cause, gave a fixed price, and the basement has been dry ever since."
"They showed up on time, respected the house, and the sump system has handled every storm since."
"Same crew from start to finish, all in writing. After 40 years in business, you can tell they know foundations."
"Straight answers and no upsell. The written warranty gave us real peace of mind. Worth every penny."
