When you need it

Signs of a settling foundation

Settling happens when the soil under part of the footing can no longer carry the load. Piering fixes it by reaching past that weak soil. Signs it's time:

A corner or side droppingOne part of the house lower than the rest, often with cracks fanning from window corners.
Gaps at the top of wallsSpace opening where interior walls meet the ceiling as the floor drops away.
Sloping floorsA clear tilt toward one wall; a marble rolls on its own.
Exterior stair-step cracksCracks climbing the brick or block outside, wider at the top.

The methods

How piers stabilize a home

Push piers

Steel piers hydraulically driven straight down under the footing until they hit soil strong enough to carry the load. Best for heavier structures.

Helical piers

Screwed into the ground like a large screw, ideal for lighter loads and softer soils. Installed with less vibration.

Stabilize, then lift

Once piers reach stable ground, the contractor secures the foundation and attempts to lift the settled section back toward level, as far as the structure safely allows.

Crawl space jacks

For a sagging floor over a crawl space, adjustable steel jacks and new supports re-level the floor above.

Piering FAQ

Common questions

What is underpinning?

Underpinning strengthens and stabilizes a foundation that's settling by transferring its weight down to stable soil or bedrock. In practice that usually means steel piers driven under the footing until they reach ground that can carry the load, then the foundation is secured to them.

What's the difference between push piers and helical piers?

Push piers are hydraulically driven straight down using the weight of the house for resistance, which suits heavier structures. Helical piers screw into the ground and work well for lighter loads and softer soils. The contractor selects the type based on your home and the soil at your site.

Can piers lift my foundation back up?

Often, yes. Once piers reach stable soil the contractor can try to lift the settled section back toward its original position. How much lift is safe depends on the structure, so the goal is to stabilize first and recover as much elevation as the house allows without causing new damage.

How long do piers last?

Steel piers are engineered for the long term and typically come with a manufacturer's warranty. Once your foundation is bearing on stable soil, the settling that caused the problem is addressed at its source. The sinking foundation guide explains the process in depth.
