Why Choose Us

Why Washington, DC Property Owners Choose SGP Waterproofing for Foundation Crack Repair

Not every Washington, DC 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

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

The Full Scope of Our Washington, DC Foundation Crack Repair Work

Every Washington, DC 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

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

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

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

How It Works

From Call to Resolution: How Foundation Crack Repair Works in Washington, DC

01

Call & Crack Description

Photos texted ahead of time help us prep for the visit and sometimes speed up scheduling.

02

On-Site Crack Classification

A technician measures crack width, checks for wall bowing, and determines whether it's structural, cosmetic, or actively leaking.

Written Injection Quote

You'll get a price based on crack length and material — epoxy or polyurethane — before any drilling starts.

04

Injection & Cure Verification

We check the injection ports after curing to confirm the material fully filled the crack before we consider the job done.

FAQ

What Washington, DC 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?▼

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 Washington, DC buyers, sellers, and lenders commonly request.
