Piering & Underpinning
Cracks in upper-level sheetrock or significant settling that makes floors unlevel often calls for piering beneath your foundation footing. Working with a structural engineer, we drive steel piers to permanently support your foundation.

When The Ground Under Your Footing Gives
Bowing walls are about soil pushing sideways. Settling is about soil failing underneath. When the ground beneath a footing loses bearing capacity, whether from clay shrinking during drought, poorly compacted fill from the original build, or erosion from a plumbing leak or bad drainage, that section of the house goes down with it.
Because the house settles unevenly, the frame racks. That is why the visible symptoms often appear well above the basement: cracks radiating from door and window corners upstairs, doors that stop latching, floors that slope. The drywall is showing you what the footing is doing.
How Piering Works
Engineer-specified scope
Piering is structural work, and the number, placement, and depth of piers should be specified by a structural engineer rather than estimated. We work from that specification. It means the scope is set by someone who does not profit from making it bigger.
Piers driven to capacity
Steel piers are driven down past the unstable soil to material capable of carrying the load. Depth is determined by what is under your house, which is why it is not a fixed number quoted in advance.
Transfer the load
Brackets at the footing transfer the weight of the structure onto the piers, so the house is bearing on the piers rather than on soil that has already proven it will not hold.
Stabilize, and lift where it is prudent
The first objective is stopping further movement. Some recovery of elevation is sometimes achievable, but how much is realistic depends on the structure. Attempting to force a settled house back to level can do more damage than the settlement did, and any responsible contractor will tell you that.
Fix the water that caused it
Where settlement traces to drainage or a leak, that gets addressed. Piering the house and leaving the erosion running is an expensive way to buy time.
Signs Of Foundation Settlement
Common indicators
Stair-step cracking in exterior brick, cracks radiating from the corners of doors and windows, interior doors that stick or no longer latch, floors that slope or feel unlevel, gaps opening where trim meets wall or ceiling, and cracks that keep reopening after being patched.
Worth knowing
Not all settlement needs piering. Houses settle a little as a normal matter, and some cracking is age rather than active movement. What matters is whether it is still moving. That is what the inspection determines, and it is why we would rather look than guess.
What Determines The Cost
We do not publish a price, because a number without seeing your foundation is a guess. Here is what actually moves it, so you know what we are looking at during the free inspection.
- Number of piers, which the engineer specifies based on the loads
- Depth required to reach adequate bearing, which varies by site
- Interior versus exterior pier placement and access to each location
- Excavation at each pier location
- Structural engineering involvement
- Any drainage or plumbing repair addressing the cause of the settlement
Piering & Underpinning FAQs
Doors that stopped latching, drywall cracks from door and window corners, sloping floors, and stair-step cracks in exterior brick are the usual signals. Whether they mean active settlement or old movement that has stopped is what an inspection determines. The inspection is free, which makes finding out straightforward.
It stabilizes the foundation so it stops moving, and some elevation recovery is sometimes possible. How much is realistic depends on the structure, and forcing a settled house back to level can crack finishes that are currently intact. Anyone promising a full lift before looking at your house is guessing.
As deep as needed to reach soil capable of carrying the load, which varies from site to site. That is why depth is not quoted as a fixed number up front and why the engineer specification matters.
There is excavation at each pier location, inside or outside depending on placement. Most residential projects run days rather than weeks. We will walk you through exactly where the piers go and what that looks like in your yard or basement.
For piering, yes, and it is in your interest. An engineer determines what your house actually requires. That protects you from an over-scoped job and from an under-scoped one, and it means the recommendation is not coming from the party being paid to install it.
