What Is Underpinning?
Underpinning is a specialized method to strengthen, deepen, or stabilize existing foundations. We extend footings to competent bearing strata and improve load transfer, which helps correct settlement and supports new loads from additions or renovations.

Visible cracks in walls or floors, or doors/windows out of plumb
Settlement or sloped, uneven floors
