Crawl Space Encapsulation and Repair Services in Sioux City

Crawl space issues stem from moisture and humidity, and can cause structural damage, poor air quality, and unwanted insects and other pests. Whether you’re looking to prevent the issues or repair damage that’s already occurred, Thrasher has solutions to meet your needs. We offer free in-home inspections for Sioux City homeowners, including a customized repair solution for your home.

Concrete Leveling, Repair and Resurfacing in Sioux City

Cracked or uneven concrete sidewalks, driveways and patios are not only an eyesore, but can create a tripping hazard around your home. Thrasher can lift, level and protect the concrete surfaces around your home with our unique concrete repair products. We use PolyLevel polyurethane foam to lift and level concrete back to its original position, and silicone-based caulking to repair surface cracks. We also offer permanent sealant to prevent additional damage, and resurfacing options for a brand-new concrete look without the mess and disruption of total replacement. Contact us today for a free, no-obligation inspection.

Sioux City Radon Testing and Guaranteed Radon Mitigation Services

Radon is the leading cause of lung cancer among non-smokers, and high radon levels in your home can mean you and your family are at risk. Thrasher mitigation systems include a 10-year warranty, during which time we guarantee levels at or below the EPA action level of 4.0 pCi/L. Contact us for a free consultation and quote for a radon mitigation system in your home today.

There's Only One Right Way.

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 Omaha homeowners protect their largest investment 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.
