Why Choose Us

Why Plainview, NY 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

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

The Full Scope of Our Plainview, NY Foundation Crack Repair Work

Every Plainview, 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

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

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

We also check for bowing alongside stair-step cracks, since that combination can point to a bigger structural issue.

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

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?▼

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?▼

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?▼

Turnaround is usually fast enough to fit within a typical closing timeline.
