Johnson County clay: heavy, expansive, and relentless. It's why we stay busy here every week of the year.

Foundation Repair & Waterproofing | Johnson County, KS

Last updated April 2026

Johnson County sits on some of the heaviest expansive clay in the greater Kansas City metro. The clay swells when it rains, shrinks when it dries, and puts constant pressure on foundations year-round. Homes built from the 1960s through the 1990s — the bulk of JoCo's housing stock — are right in the window where decades of clay movement finally overwhelm the original construction.

Frequently Asked Questions — Johnson County

What causes foundation problems in Johnson County homes?

Johnson County sits on some of the heaviest expansive clay in the metro. It swells when it rains, shrinks when it dries, and puts constant pressure on foundations. Homes built from the 1960s through the 1990s — which covers a huge chunk of JoCo — are right in the window where settling and bowing walls start showing up. The newer subdivisions in south Olathe and Spring Hill have their own issues too, usually from poor soil compaction during construction.

How much does foundation repair cost in Johnson County?

Depends entirely on what's wrong. A simple crack repair or a couple of carbon fiber straps might run $2,000 to $4,000. Push piers to stabilize a settling section of foundation typically fall between $4,000 and $12,000. Full-perimeter pier jobs or major wall stabilization can go higher. We do free inspections and same-day written estimates, so you'll know exactly what you're looking at before you decide anything.
