Why Choose Us

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

Not every Kingston, NJ 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.

1

Licensed Crack Classification

Misclassifying a crack is the most common mistake in this trade, and it's the first thing we check on every Kingston, NJ job.

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

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

Every Kingston, NJ 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

Polyurethane cures even in the presence of water, which makes it the right call for a crack that's actively letting water through.

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.

Crack Repair

Pre-Sale Crack Inspection & Documentation

Selling a Kingston, NJ home with a flagged foundation crack? We can inspect, repair, and provide documentation for the buyer's lender or inspector.

Call & Crack Description

Tell us the crack's location, whether it's actively leaking, and roughly how wide it is so we can bring the right materials.

FAQ

What Kingston, NJ Customers Ask Us Most About Foundation Crack Repair

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

Crack classification is separate from water contamination — we assess whether the crack is structural or cosmetic based on width, pattern, and any wall bowing.

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?

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?

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?

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 Kingston, NJ buyers, sellers, and lenders commonly request.
