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.
No hourly billing surprises — if a crack turns out more complex once opened, we discuss it with you before proceeding.
Polyurethane, which stays flexible and expands to fill voids, is used for active leaks and seasonal movement.
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.
We document displacement with photos and measurements, referring to a structural engineer when warranted before recommending reinforcement.
A specialized repair beyond simple injection — we walk you through the engineering rationale before recommending it.
Some cracks are fed by poor exterior grading directing water straight at the foundation — injecting without correcting grading just delays the next one.
Four steps, start to finish — from the first call to a properly classified and injected crack.
Photos texted ahead of the visit help the technician arrive with a working classification hypothesis.
You'll get a text update if the window shifts due to an emergency ahead of you.
You'll see the classification explained in plain terms — why this crack fits polyurethane versus needing a structural referral.
If a crack needs engineering review instead of injection, we'll say so plainly rather than injecting a crack that shouldn't be.
