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.
Trucks carry both epoxy and polyurethane injection systems so the crew can match resin to crack type on the first visit.
Quotes are priced per linear foot of crack and resin type, given in writing before any injection begins.
Polyurethane, which stays flexible and expands to fill voids, is used for active leaks and seasonal movement.
Each service below is scoped specifically to foundation crack repair, not a generic waterproofing menu with the name swapped in.
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.
Here's what happens between your call and a resolved foundation crack.
Photos texted ahead of the visit help the technician arrive with a working classification hypothesis.
Trucks carry both polyurethane and epoxy systems, plus a crack width gauge for precise classification on site.
Pricing is quoted per linear foot in writing before injection begins.
Injected cracks are checked for full-depth fill with a follow-up inspection, not just sealed on the surface.
