We classify every crack before injecting it — structural cracks get epoxy, active leaks get flexible polyurethane, and both get a written scope before we start.
Not every La Grange, IL foundation crack needs the same material or approach. A vertical settlement crack behaves differently than a stair-step block crack, and we adjust injection technique and material to match what's actually happening in the wall.
Misclassifying a crack is the most common mistake in this trade, and it's the first thing we check on every La Grange, IL job.
Most crack injection appointments can be scheduled within a day or two of your call.
A single crack repair is one of the most predictably priced jobs we do — no surprise scope creep.
We carry both structural epoxy and flexible polyurethane so the crew can match material to the crack on the same visit.
We scope every Foundation Crack Repair job in person before quoting it, since two properties with the same symptom rarely need the same fix.
Epoxy-injected cracks regain much of their original structural strength, which matters for load-bearing foundation walls.
Cracks that are still weeping get flexible polyurethane, which expands into voids and stays flexible enough to handle minor seasonal movement.
We also check for bowing alongside stair-step cracks, since that combination can point to a bigger structural issue.
We document crack width and location with photos before and after injection so you have a record of the repair.
Selling a La Grange, IL home with a flagged foundation crack? We can inspect, repair, and provide documentation for the buyer's lender or inspector.
Tell us the crack's location, whether it's actively leaking, and roughly how wide it is so we can bring the right materials.
We also check the exterior grading near the crack, since poor drainage is often what caused it in the first place.
You'll get a price based on crack length and material — epoxy or polyurethane — before any drilling starts.
We check the injection ports after curing to confirm the material fully filled the crack before we consider the job done.
"Crack in our basement wall had been leaking for a year before we finally called. Injection took less than an afternoon and it's been dry since."
— La Grange Seller
"Polyurethane injection stopped an active leak the same day they showed up — didn't expect it to be that fast."
— La Grange Homeowner
"Had two cracks — one needed epoxy, one needed polyurethane. They matched material to each one instead of using the same thing on both."
— La Grange Customer
"Fast, clean work — no mess left behind after the injection ports were patched."
— La Grange Homeowner
Crack classification is separate from water contamination — we assess whether the crack is structural or cosmetic based on width, pattern, and any wall bowing.
Catching a crack early with injection usually costs less than waiting until it's actively leaking.
We make the call on-site after inspecting the crack, not before we've seen it.
Most single-crack injections are completed in a few hours during one visit.
If new movement occurs elsewhere in the wall, that's a separate issue we'd assess independently.
Yes — we provide before-and-after photos and a repair summary that La Grange, IL buyers, sellers, and lenders commonly request.
