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 New Hyde Park, 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 New Hyde Park, NY job.
An actively leaking crack rarely waits for a convenient afternoon — we prioritize dispatch for New Hyde Park, 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.
Polyurethane expands to fill voids behind an actively weeping wall; epoxy is reserved for cracks that need structural bonding.
Every New Hyde Park, 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.
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.
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.
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.
We check the injection ports after curing to confirm the material fully filled the crack before we consider the job done.
"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."
— New Hyde Park Seller
"They explained why our crack was structural and not just cosmetic, which the previous contractor never bothered to check."
— New Hyde Park Homeowner
"Had two cracks — one needed epoxy, one needed polyurethane. They matched material to each one instead of using the same thing on both."
— New Hyde Park Customer
"Stair-step crack in our block wall had us worried about the whole foundation. Turned out to be isolated and fixable with injection."
— New Hyde Park 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.
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.
Turnaround is usually fast enough to fit within a typical closing timeline.
