Moderate risk About 8% of Fisher County's soil area is high shrink-swell (expansive) clay — far below the Texas average of 32%, and below the national average of 17%. That places it #169 of 206 Texas counties for foundation soil risk.
Share of the county's ~575,744 acres of USDA-mapped soil with linear extensibility ≥ 6% in the top meter (SSURGO).

Expansive clay swells as it takes on water and shrinks as it dries, and that repeated movement is what lifts and drops a foundation unevenly — opening stair-step cracks, racking door and window frames, and, left unmanaged, cracking slabs and footings. Fisher County's exposure is moderate. At 8% high-expansive soil, Fisher County carries real but uneven risk — trouble concentrates on lots with poor drainage, cut-and-fill grading, or aging plumbing leaks rather than striking every home. A soil-aware inspection beats assuming the worst.
Fisher County's shrink-swell risk is concentrated in the Tillman soil series alongside Winters and Vernon — clays the USDA maps as strongly expansive, swelling and shrinking with every wet–dry cycle. Homes built on these series most need the drainage and moisture discipline above; a lot-level soil report (or the county NRCS survey) shows which one sits under a given address.
| County | High-risk soil | |
|---|---|---|
| Higher risk → | Parker County | 8.6% |
| This county | Fisher County (#169 of 206) | 8.0% |
| Lower risk → | Lipscomb County | 7.5% |
For context, the average Texas county is 32% high-expansive soil and the average U.S. county is 17%.
Foundation repair is one of the most over-sold jobs in home services — quotes for the same house can vary 3×. Before you sign anything, learn how to get honest bids and what a fair price looks like.
How to get repair quotes →Costs follow the same structure everywhere — from a few hundred dollars for a single crack injection to $8,000–$25,000+ for pier stabilization on a settling home. The right fix depends on the actual cause of movement, so get a diagnosis before committing to clay-specific work. See the full foundation repair cost guide for method-by-method pricing.
Risk metrics are computed from USDA SSURGO soil survey data (linear extensibility of soil components, area-weighted by county). Soil varies lot to lot — this is county-scale context, not a substitute for a site-specific geotechnical or structural assessment.
