Crack Repair in Alpine, CA.
Crack Repair for Alpine homes, done by an experienced San Diego County foundation crew. Not every crack is a structural crack, and not every crack needs the same fix. Hairline shrinkage cracks at the slab edge are cosmetic.
Why is crack repair different in East County San Diego?
East County diagonal cracks are common after long droughts when expansive clay shrinks under one corner of the house. Crack injection without addressing the soil cause is wasted money; we usually pair injection with drainage and stabilization.

How does Alpine's climate affect this service?
Alpine foundation work is rural-residential and large-lot custom-estate scope at higher East County elevations (1,800-2,500 feet). Hillside settlement, post-Cedar-Fire rebuild, snow-cycle freeze-thaw considerations at the higher elevations, and well-and-septic-influenced planning dominate.. East County diagonal cracks are common after long droughts when expansive clay shrinks under one corner of the house.
Should I use epoxy or polyurethane?
Epoxy bonds the two sides of the crack back into a structural unit, but only if the crack is dry and stable. Polyurethane expands when it contacts water and seals against active leaks but does not restore structural strength. If the crack is dry and the foundation is not actively moving, we use epoxy. If the crack is wet, weeping, or active, we use polyurethane and address the underlying movement separately.
Can I just use a DIY crack kit from the hardware store?
For a hairline cosmetic crack on the inside face of a stem wall, a DIY kit is fine. For anything full-depth, anything weeping, or anything you suspect is structural, the DIY kits do not put enough product into the full depth of the crack. They seal the surface and the crack reopens behind the patch.
