A crack in your foundation wall isn't automatically an emergency, but it's never something to paint over and hope for the best — we classify it correctly before recommending anything.
Call +1-866-476-1348
Four commitments that separate a properly trained foundation crack repair crew from a generalist showing up with a truck and a hope.
Classification includes checking for horizontal displacement and correlating findings with door or window frame misalignment throughout the home.
Non-emergency evaluations are typically scheduled within a few days of your initial call.
Structural cracks needing engineering review are priced separately and clearly, never bundled silently into a standard quote.
Epoxy, which cures rigid and restores bond strength, is reserved for stable, non-water cracks needing structural repair.
We don't run a one-size-fits-all playbook — every foundation crack repair job starts from these core service components, adapted to what your property actually needs.
Because it cures flexible, it accommodates the minor seasonal movement concrete foundations naturally undergo without re-cracking at the same point.
Reserved for confirmed non-active cracks — injecting epoxy into a still-moving crack just cracks the epoxy itself.
Stair-step cracking in block or brick walls typically signals soil pressure or settlement beyond what injection alone resolves.
A specialized repair beyond simple injection — we walk you through the engineering rationale before recommending it.
We evaluate downspout extensions, soil slope, and window well drainage as part of a complete repair.
Four steps, start to finish — from the first call to a properly classified and injected crack.
Describe what you're seeing — a damp wall, crack width, whether water is actively coming through — and dispatch routes a crew with the right resin loaded.
Trucks carry both polyurethane and epoxy systems, plus a crack width gauge for precise classification on site.
You'll see the classification explained in plain terms — why this crack fits polyurethane versus needing a structural referral.
Repairs carry a written warranty against re-leaking at the treated location.
