Why Choose Us

What Sets Our Foundation Crack Repair Team Apart in Kensington, NY

Misclassifying a crack is the single most common mistake in this trade — treating a structural crack with the wrong material, or injecting a crack that actually needed a broader drainage fix behind it. We classify before we inject, every time.

1

Licensed Crack Classification

Our technicians are trained to tell a cosmetic hairline crack apart from one that signals structural movement, before recommending a fix.

2

Fast Local Response

Most crack injection appointments can be scheduled within a day or two of your call.

3

Flat-Rate Injection Pricing

A single crack repair is one of the most predictably priced jobs we do — no surprise scope creep.

4

Epoxy & Polyurethane Both On the Truck

We carry both structural epoxy and flexible polyurethane so the crew can match material to the crack on the same visit.

What We Do

Comprehensive Foundation Crack Repair Solutions in Kensington, NY

Every Kensington, NY Foundation Crack Repair job starts with an inspection, not a generic package — here's what that typically includes.

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

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.

Crack Repair

Pre-Sale Crack Inspection & Documentation

Fast turnaround matters during a real estate transaction, and we prioritize scheduling for time-sensitive pre-sale repairs.

FAQ

Foundation Crack Repair Questions We Hear Every Week

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?▼

We make the call on-site after inspecting the crack, not before we've seen it.

How long does crack injection take?▼

Multiple cracks or hard-to-access areas can extend the timeline, which we'll flag in the written quote.

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 Kensington, NY buyers, sellers, and lenders commonly request.
