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 Greensboro, AL 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 Greensboro, AL 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.
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.
Polyurethane cures even in the presence of water, which makes it the right call for a crack that's actively letting water through.
We also check for bowing alongside stair-step cracks, since that combination can point to a bigger structural issue.
Vertical cracks are usually settlement-related and often isolated; horizontal cracks can indicate hydrostatic pressure pushing on the wall and get flagged for further evaluation.
Fast turnaround matters during a real estate transaction, and we prioritize scheduling for time-sensitive pre-sale repairs.
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.
We explain why we're recommending one material over the other so the choice isn't a black box.
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."
— Greensboro Seller
"Polyurethane injection stopped an active leak the same day they showed up — didn't expect it to be that fast."
— Greensboro Homeowner
"Had two cracks — one needed epoxy, one needed polyurethane. They matched material to each one instead of using the same thing on both."
— Greensboro Customer
"Stair-step crack in our block wall had us worried about the whole foundation. Turned out to be isolated and fixable with injection."
— Greensboro 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.
Epoxy is better for structural bonding on a non-leaking crack; polyurethane is better for a crack that's actively weeping since it cures even with water present.
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.
