The Midwest's Most Trusted Foundation Repair Company

From small beginnings operating as a duo out of their farmhouse in 1975, Greg and Nancy Thrasher took a “whatever it takes” approach to keeping customers happy. Helping homeowners protect their largest investment by repairing wet basements and failing foundations meant using quality products, installing them properly and standing behind the work.

For years, we provided basement waterproofing services in the Omaha area, and grew to become one of the largest basement and foundation repair, concrete repair & leveling, and radon mitigation contractors in the Midwest. Today, we serve homeowners across Nebraska, Kansas, Western Iowa and Northwest Missouri from our offices in Omaha and Wichita.

The Thrasher crew that came was nice and very professional. They were incredibly neat and clean. I actually think our basement is cleaner after they left.
