Foundation Piering & Underpinning in Cary, North Carolina
When part of a house settles faster than the rest, fixing the cracks does not fix the cause. Foundation piering and underpinning transfers the weight of your home to stable soil so the settlement stops, and where conditions allow, the structure can be lifted back toward level.
Foundation Piering & Underpinning for Cary Homes: What We Look For and How We Fix It
Cary sits on a mix of stiff red clay and, in newer neighborhoods, fill soil that was graded and compacted to make building lots. Clay swells when it is wet and shrinks when it dries, and fill can keep consolidating for years, so a footing that was fine on day one can slowly sink on one side. When it does, the signs show up in the house: diagonal cracks above doors, a sloping floor, or a gap opening between a wall and the ceiling.
Piering works by driving steel piers down past the unstable soil to a depth where the ground can carry the load, then attaching brackets to the footing so the house rests on the pier instead of the soil beneath it. Depending on the home and the soil, we may recommend push piers, helical piers, or a combination, and we explain why before anything is installed. We also review site drainage, because water pooling near one corner is frequently what started the settlement.
Signs You May Need Foundation Piering & Underpinning
- Diagonal cracks radiating from the corners of doors and windows
- Floors that slope or feel bouncy in one part of the house
- A chimney or porch pulling away from the main structure
- Gaps between the foundation and the soil, or between trim and the wall

Common Questions
Foundation Piering & Underpinning FAQ
How do I know if my foundation needs piers?
The clearest sign is settlement that is ongoing or uneven: cracks that keep growing, doors that stop closing, or floors that slope. A hairline crack alone rarely needs piers. We evaluate movement, soil conditions, and the pattern of damage before recommending anything.
Can piering lift a house back to level?
In many cases the house can be raised at least part of the way back once piers are set, but how much depends on the structure and how long it has settled. We are honest about what is realistic, because lifting too aggressively can damage plumbing and finishes.
Is piering disruptive to the yard?
Piers are installed in small excavations along the foundation, so the work is contained to the perimeter rather than the whole yard. We plan access to protect landscaping, patios, and utilities, and we restore the excavated areas when the work is done.
