Stair-step, horizontal, or widening cracks are a sign of movement. We seal and stabilise at the source, with a written warranty.
Takes 30 seconds. We call you back within 2 business hours.
We never share your information. No obligation, no pressure, no sales pitch.
Most cracks come from soil movement and water pressure, not bad concrete. Chicago clay swells and shrinks with moisture, and freeze-thaw winters do the rest.
A surface patch hides the crack for a season. We address what is actually moving, so the repair holds.
We diagnose the root cause on site and explain it in plain language.
A fixed price up front, no hourly billing and no pressure to decide.
Our own trained crews complete the work cleanly and on schedule.
You get it in writing, and we stand behind it for the full term.

"Honest and fair. They fixed the crack two other companies had misdiagnosed, and explained every step."
"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."
