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 Old Westbury, 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 Old Westbury, NY job.
An actively leaking crack rarely waits for a convenient afternoon — we prioritize dispatch for Old Westbury, NY 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 Old Westbury, NY Foundation Crack Repair job starts with an inspection, not a generic package — here's what that typically includes.
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.
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.
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.
Tell us the crack's location, whether it's actively leaking, and roughly how wide it is so we can bring the right materials.
A technician measures crack width, checks for wall bowing, and determines whether it's structural, cosmetic, or actively leaking.
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.
"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."
— Old Westbury Seller
"Polyurethane injection stopped an active leak the same day they showed up — didn't expect it to be that fast."
— Old Westbury Homeowner

— Old Westbury Customer
"Fast, clean work — no mess left behind after the injection ports were patched."

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.
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.
Multiple cracks or hard-to-access areas can extend the timeline, which we'll flag in the written quote.
If new movement occurs elsewhere in the wall, that's a separate issue we'd assess independently.
