Why Choose Us

Why Franklin Lakes, NJ Property Owners Choose SGP Waterproofing for Foundation Crack Repair

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

An actively leaking crack rarely waits for a convenient afternoon — we prioritize dispatch for Franklin Lakes, NJ cracks that are currently letting water in.

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

Polyurethane expands to fill voids behind an actively weeping wall; epoxy is reserved for cracks that need structural bonding.

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

Structural cracks that aren't actively leaking get epoxy injection, which bonds the concrete back together rather than just sealing the surface.

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

Frequently Asked Questions 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?

We repair cracks of nearly any size — hairline cracks are often the easiest and cheapest to seal before they widen further.

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?

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

Will the crack reopen after injection?

A properly injected crack is unlikely to reopen at the same spot, and our work comes with a written warranty covering exactly that.

Do you provide documentation for real estate transactions?

Yes — we provide before-and-after photos and a repair summary that Franklin Lakes, NJ buyers, sellers, and lenders commonly request.
