How much does foundation repair cost?

Crack injection runs $400–$1,500. Slab jacking / mudjacking is $500–$3,000. Steel push piers cost $1,500–$3,000 per pier (10–15 piers typical) so a full job runs $15,000–$45,000. Helical piers add $300–$500 each on top of that.

Push piers vs. helical piers - which is better?

Push piers are best for heavy structures with deep soils - they reach load-bearing strata. Helical piers screw in and bear immediately, ideal for lighter loads, lifts, and decks. A reputable engineer chooses based on soil tests, not what they sell.

How long does foundation repair take?

Most piering jobs finish in 2–5 days. Slab jacking is often a single day. Major underpinning with multiple piers can run 1–2 weeks plus engineering.

Will the cracks come back?

Properly installed piers stop further settlement. Hairline cosmetic cracks may reappear from normal expansion/contraction, but structural movement should not return - your warranty covers re-leveling if it does.

Is the warranty transferable?

Yes - the major networks (Groundworks, Olshan, Ram Jack, Foundation Supportworks) all offer transferable lifetime warranties, which holds value at resale.
