What We Do

What Our Foundation Crack Repair Service Actually Covers

We scope every Foundation Crack Repair job in person before quoting it, since two properties with the same symptom rarely need the same fix.

Crack Repair

Low-Pressure Epoxy Injection

Epoxy-injected cracks regain much of their original structural strength, which matters for load-bearing foundation walls.

Crack Repair

Polyurethane Injection for Active Leaks

Cracks that are still weeping get flexible polyurethane, which expands into voids and stays flexible enough to handle minor seasonal movement.

Crack Repair

Stair-Step Block Crack Repair

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.

Crack Repair

Vertical & Horizontal Wall Crack Sealing

We document crack width and location with photos before and after injection so you have a record of the repair.

FAQ

What Lake Grove, NY Customers Ask Us Most About Foundation Crack Repair

How do you classify contaminated water versus a structural crack repair?

Active leaks get flexible polyurethane regardless of classification, since stopping water intrusion is the immediate priority.

Will you repair hairline cracks or only large ones?

Catching a crack early with injection usually costs less than waiting until it's actively leaking.

Is epoxy or polyurethane better for my crack?

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.

How long does crack injection take?

Most single-crack injections are completed in a few hours during one visit.

Will the crack reopen after injection?

If new movement occurs elsewhere in the wall, that's a separate issue we'd assess independently.

Do you provide documentation for real estate transactions?

Yes — we provide before-and-after photos and a repair summary that Lake Grove, NY buyers, sellers, and lenders commonly request.
