Foundation Crack Repair for Cary Homes: What We Look For and How We Fix It
Foundation cracks in Cary tend to trace back to the same few causes: the red Piedmont clay swelling and shrinking with the weather, water pooling against the wall after heavy summer storms, or fill soil that was still settling when the house was built. A hairline vertical crack near a window or a corner is often just concrete curing and shrinking, while a wide, stair-step, or horizontal crack is telling you the soil or the wall is moving. The first job is telling those two apart.
We measure and map the crack, check whether it is still active, and look at what is happening outside the wall — grading, downspouts, and drainage often explain more than the crack itself. Stable cracks are typically sealed from the inside with epoxy injection (which bonds the wall back together) or flexible polyurethane injection (which stays elastic and stops leaks). If a crack is widening or a wall is shifting, sealing alone will not hold, and we will recommend addressing the movement first so the repair does not simply reopen.

Common Questions
Foundation Crack Repair FAQ
Are foundation cracks always serious?
No. Many hairline vertical cracks are cosmetic and simply reflect concrete shrinking as it cured. What matters is the pattern: cracks that are wide, growing, horizontal, or stair-stepped through block usually point to movement or pressure that deserves a proper look. We tell you plainly which category yours falls into.
Should I use epoxy or polyurethane to seal a crack?
It depends on the goal. Epoxy is rigid and bonds the two sides of a crack back together, which suits stable cracks in poured concrete. Polyurethane stays flexible and expands to fill the crack, which is better for cracks that leak or may move slightly with the seasons.
Will the crack come back after it is repaired?
If the crack was caused by a one-time event like curing shrinkage, a proper injection normally holds. If the soil or drainage that caused it is still active, a new crack can form elsewhere, which is why we look at water management and movement before we recommend sealing alone.
