Foundation repair methods for Plano homes
Piers, slab jacking, crack repair and house lifting, with published cost ranges and what to ask.
Contractors use several methods, and which one fits depends on what's wrong. The costs below are HomeGuide's published national ranges from February 2026, not quotes.
Piers (underpinning)
In general, piers are columns installed beneath a foundation to carry it on deeper, more stable soil, and in some systems to lift it back toward level. HomeGuide lists underpinning at $10,000 to $20,000 and steel piers at $1,000 to $1,600 per pier.
Ask: how many piers, where each one goes, what they're made of, who designed the layout, and whether an engineer is involved.
Slab jacking or mudjacking
In general, material is pumped through small holes in a settled concrete slab to fill voids underneath and raise it. HomeGuide lists this at $4,500 to $9,000.
Ask: what material is used, how far the slab is expected to rise, and what happens if it settles again.
Crack repair
Epoxy injection or stitching is listed at $250 to $800 per crack. Sealing a crack doesn't fix whatever caused the movement, so ask what caused it and whether it has stopped.
House lifting
For severe cases, HomeGuide lists house lifting at $10,000 to $40,000, and $20,000 to $100,000 when it comes with a new foundation.
Slab or pier and beam
Homes on a concrete slab and homes on a raised pier-and-beam foundation are repaired differently. The cost data we have doesn't separate them, so ask any contractor for the plan and price in writing, with the work described for your type of foundation.
Questions for any method
- Why this method for my house, and what else did you consider?
- Who designs it, and is an engineer's letter part of the job?
- Is the permit included, and who pulls it? See Plano permits.
- What does the warranty cover, for how long, and does it transfer?
- What is not included in the price?

Common questions
What are foundation piers?
In general, columns installed beneath a foundation to carry it on deeper, more stable soil. HomeGuide lists underpinning with piers at $10,000 to $20,000 and steel piers at $1,000 to $1,600 each.
Is slab jacking cheaper than piers?
HomeGuide's published ranges are $4,500 to $9,000 for slab jacking and $10,000 to $20,000 for piers, but they solve different problems, so ask which one your house needs and why.
