Clay soil moves, and your foundation moves with it. We find exactly what shifted, explain why, and fix it with engineered steel piers.
A local specialist will evaluate your foundation, walk you through the findings, and send a clear estimate. No cost, no pressure.
Foundation problems in Southern California, Arizona, and Nevada almost always start with the soil. Clay soil acts like a sponge under your house: it swells when it rains and shrinks through the dry months, and your foundation rides that movement year after year.
Eventually the signs show up where you live, doors that stick, floors that slope, cracks that climb a wall in a stair step pattern.
Dalinghaus Foundation Repair has repaired more than 2,000 foundations since brothers Brian and Brad Dalinghaus founded the company in 2011. Every repair starts the same way: we measure. A floor elevation survey maps how your home sits before anyone recommends anything, so the fix matches the actual problem instead of a guess.
When piers are the answer, we install galvanized steel helical or push piers and log the torque and depth on every one.
No band-aids, no pressure, and no work you do not need. That is what Never Settle means to us.

Most foundation repair problems start as small symptoms. Catching them early is the difference between a small, planned fix and a major reconstruction. These are the warning signs we see most often.
Dalinghaus installed the helical pile foundation and erected the structure for a solar canopy over a staff parking lot in Southern California, working in four phases so the lot stayed open.
Show project
The back of an Irvine home had settled about 3 inches over roughly ten years. Ten helical piers went in over two days, and a 30 minute lift brought the back half of the home up 3 inches.
Show project
A hillside home in Rancho Palos Verdes split in half as the ground slid toward the slope. Dalinghaus installed helical piers about 30 feet down to competent strata or bedrock beneath it.
Show project
A beachside home in Rancho Palos Verdes settled 16 inches in a couple of months. Steel piers were driven to load bearing soil or bedrock at each excavated location, with a lift planned once they were in.
Show project
A San Clemente hillside home had settled about 2 inches and was moving toward the slope behind it. Vertical helical piers and helical tieback anchors stabilized the home and recovered part of the drop.
Show project
Two helical deck piers let a San Clemente hillside deck grow by about 12 feet, at a home Dalinghaus had lifted about 16 inches earlier.

The common early signs are doors and windows that stick, cracks in drywall or stucco, sloping or bouncy floors, and stair step cracks in brick or block.
