What foundation repair costs in McKinney (2026)
Every foundation job in McKinney is quoted after a level survey, with each pier listed and priced. The table is where most jobs in Collin County land. The notes say what pushes a job toward one end of a range or the other.
| Service | Typical price in Collin County | Notes |
|---|---|---|
| Foundation inspection and level survey (homeowner) | free | Elevation map, written report, and a per-pier drawing if repair is needed |
| Independent engineer's report | $450 to $800 | For a sale, a lender, an insurance claim, or a permit that wants sealed drawings |
| Pressed concrete pier, installed | $400 to $700 | Driven to refusal under the grade beam; the standard slab repair |
| Steel pier, installed | from $1,200 | Where the clay runs too deep for pressed concrete to reach stable soil |
| Typical slab pier job (8 to 20 piers) | $4,000 to $12,000 | Count follows how much of the perimeter moved, not the size of the house |
| Pier-and-beam releveling | from $2,500 | Shims and a few new piers; beam and sill work quoted by the foot |
| Drainage correction | $2,500 to $6,500 | Downspout extensions at the bottom; a french drain on two sides with a curb outlet at the top |
| Concrete leveling | from $650 | By the square foot lifted; one sidewalk panel is the low end |
| Hydrostatic under-slab plumbing test | $275 to $425 | Standard before interior piers and after any lift |
Three things move a quote more than anything else. Pier count: a dropped corner may need six, two settled sides may need twenty. Depth: deep clay means deeper piers and sometimes steel instead of concrete. Access: interior piers through the slab, piers under a deck, and a house on a slope all take longer. A failed plumbing test adds isolation, camera work and a tunnel repair before the piers go in, and that is quoted separately once the leak is found.
There is no charge beyond what is listed for the inspection, no piers you do not need, and no fee for the warranty paperwork or its transfer to the next owner. The pier count on the day of the job is the count on the quote.
