Why Choose Us

Why Dunkirk, MD Property Owners Choose SGP Waterproofing for Foundation Crack Repair

Not every Dunkirk, MD 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

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

Pricing is based on crack length and injection material, quoted in writing before we drill any injection ports.

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

The Full Scope of Our Dunkirk, MD Foundation Crack Repair Work

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

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

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

What Dunkirk, MD 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?▼

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 Dunkirk, MD buyers, sellers, and lenders commonly request.
