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 Lake Zurich, 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 Lake Zurich, IL job.
An actively leaking crack rarely waits for a convenient afternoon — we prioritize dispatch for Lake Zurich, IL cracks that are currently letting water in.
A single crack repair is one of the most predictably priced jobs we do — no surprise scope creep.
Polyurethane expands to fill voids behind an actively weeping wall; epoxy is reserved for cracks that need structural bonding.
We scope every Foundation Crack Repair job in person before quoting it, since two properties with the same symptom rarely need the same fix.
Structural cracks that aren't actively leaking get epoxy injection, which bonds the concrete back together rather than just sealing the surface.
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 Lake Zurich, IL home with a flagged foundation crack? We can inspect, repair, and provide documentation for the buyer's lender or inspector.
Photos texted ahead of time help us prep for the visit and sometimes speed up scheduling.
A technician measures crack width, checks for wall bowing, and determines whether it's structural, cosmetic, or actively leaking.
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."
— Lake Zurich Seller
"They explained why our crack was structural and not just cosmetic, which the previous contractor never bothered to check."
— Lake Zurich Homeowner
"Had two cracks — one needed epoxy, one needed polyurethane. They matched material to each one instead of using the same thing on both."

"Fast, clean work — no mess left behind after the injection ports were patched."
— Lake Zurich Homeowner
Active leaks get flexible polyurethane regardless of classification, since stopping water intrusion is the immediate priority.
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.
A properly injected crack is unlikely to reopen at the same spot, and our work comes with a written warranty covering exactly that.
Turnaround is usually fast enough to fit within a typical closing timeline.
