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 East Setauket, 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.
Our technicians are trained to tell a cosmetic hairline crack apart from one that signals structural movement, before recommending a fix.
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 East Setauket, 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.
We explain why we're recommending one material over the other so the choice isn't a black box.
Most single-crack injections are completed in a few hours, start to finish, in one visit.

Active leaks get flexible polyurethane regardless of classification, since stopping water intrusion is the immediate priority.
We repair cracks of nearly any size — hairline cracks are often the easiest and cheapest to seal before they widen further.
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 East Setauket, NY buyers, sellers, and lenders commonly request.
