What We Do

The Full Scope of Our Princeton, MN 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

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.

FAQ

Foundation Crack Repair Questions We Hear Every Week

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?▼

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 Princeton, MN buyers, sellers, and lenders commonly request.
