Frequently asked questions

Does foundation repair need an engineer?

Most building departments will not issue a structural repair permit without a sealed plan or letter from a licensed engineer, and lenders and buyers usually ask for the same document later.

Why do estimates vary so much?

Price follows the number of piers and the depth required to reach competent soil. Two homes on the same street can differ by tens of thousands if one needs piers driven twice as deep.

How long does foundation repair take?

2-7 days of work, 3-8 weeks including engineering and permitting. Permit review and inspection scheduling are usually the largest source of variation.

What changes the price the most?

The largest cost drivers are number of piers and the depth to load-bearing soil; push piers, helical piers, slab jacking or wall anchors; engineering, soil testing and survey work.
