Underpinning is a structural repair process used to strengthen and stabilize a home’s foundation when it begins to move, sink, or show signs of cracking. Over time, changes in soil conditions, moisture levels, poor drainage, or natural settlement can cause the ground beneath a home to shift, leading to structural issues.

The underpinning process involves carefully excavating sections beneath the existing foundation and installing new, stronger supports — such as concrete footings or piers — that extend deeper into stable soil. This transfers the weight of the home onto a more secure base.

By reinforcing the foundation, underpinning helps prevent further structural damage, restores stability, and ensures your home remains safe, level, and structurally sound for years to come.
