Foundation Crack Repair
Structural and non-structural foundation crack repair, accounting for Northern Arizona's freeze-thaw cycle.
What's Included
Included in this job
- Crack assessment (structural vs. non-structural)
- Epoxy or polyurethane injection sealing, matched to the crack type
- Freeze-thaw-resistant repair material selection
- Exterior crack sealing where accessible
- Follow-up monitoring guidance for repaired cracks
- Referral to a structural engineer when a crack indicates a larger structural issue
Who It's For
Homeowners with a visible foundation crack, active water intrusion through a crack, or a crack that keeps reappearing after a previous repair.
Freeze-thaw cycling — water entering a crack, freezing, expanding, and refreezing repeatedly through a Flagstaff winter — is one of the more common causes of foundation cracks widening or reappearing in this region. We repair cracks with materials and methods suited to that specific stress pattern, not a generic patch that fails the next freeze cycle.
Common Questions
Foundation Crack Repair FAQ
Does freeze-thaw cycling make foundation cracks worse?
It can. Water that gets into an existing crack and freezes expands, which can widen the crack over repeated winter cycles. This is a real factor in Northern Arizona that a generic warm-climate repair approach doesn't always account for.
How do I know if a crack is structural?
Signs like a crack wider than roughly 1/4 inch, a stair-step pattern in block/brick, or a crack that's actively growing warrant a closer look. We'll assess what we see and refer out to a structural engineer if it looks like more than a routine repair.
