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 Glen Head, NY 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 Glen Head, NY job.
An actively leaking crack rarely waits for a convenient afternoon — we prioritize dispatch for Glen Head, NY 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.
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.
Polyurethane cures even in the presence of water, which makes it the right call for a crack that's actively letting water through.
Stair-step cracking in block foundation walls needs a different injection port pattern than a vertical crack in poured concrete, and we adjust technique accordingly.
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.
Selling a Glen Head, NY 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.
Most single-crack injections are completed in a few hours, start to finish, in one visit.
"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."
— Glen Head Seller
"Polyurethane injection stopped an active leak the same day they showed up — didn't expect it to be that fast."
— Glen Head Homeowner
"Appreciated the before-and-after photos for our records in case we ever need them for a future sale."
— Glen Head Customer
"Stair-step crack in our block wall had us worried about the whole foundation. Turned out to be isolated and fixable with injection."
— Glen Head 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.
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.
Yes — we provide before-and-after photos and a repair summary that Glen Head, NY buyers, sellers, and lenders commonly request.
