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.
Misclassifying a crack is the single most common mistake in this trade — treating a structural crack with the wrong material, or injecting a crack that actually needed a broader drainage fix behind it. We classify before we inject, every time.
Our technicians are trained to tell a cosmetic hairline crack apart from one that signals structural movement, before recommending a fix.
An actively leaking crack rarely waits for a convenient afternoon — we prioritize dispatch for Windsor, IL cracks that are currently letting water in.
Pricing is based on crack length and injection material, quoted in writing before we drill any injection ports.
We carry both structural epoxy and flexible polyurethane so the crew can match material to the crack on the same visit.
Every Windsor, IL Foundation Crack Repair job starts with an inspection, not a generic package — here's what that typically includes.
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.
Fast turnaround matters during a real estate transaction, and we prioritize scheduling for time-sensitive pre-sale repairs.
Photos texted ahead of time help us prep for the visit and sometimes speed up scheduling.
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.
"We were selling the house and the inspector flagged a foundation crack. They came out within two days, injected epoxy, and gave us documentation for the buyer's lender."
— Windsor Seller
"Polyurethane injection stopped an active leak the same day they showed up — didn't expect it to be that fast."
— Windsor Homeowner
"Had two cracks — one needed epoxy, one needed polyurethane. They matched material to each one instead of using the same thing on both."
— Windsor Customer
"Fast, clean work — no mess left behind after the injection ports were patched."
— Windsor 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.
We repair cracks of nearly any size — hairline cracks are often the easiest and cheapest to seal before they widen further.
We make the call on-site after inspecting the crack, not before we've seen it.
Multiple cracks or hard-to-access areas can extend the timeline, which we'll flag in the written quote.
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.
