Industry-Leading, Transferable Warranties and Guarantees

At Thrasher, we pride ourselves on providing permanent solutions, and stand behind our work with industry-leading, fully transferable warranties and guarantees. Most of our foundation repair, basement waterproofing and crawl space repair work is backed by a 25-year warranty. Our concrete repair work is guaranteed for 5 years, and egress windows for 10. Our radon mitigation systems come with a 10-year warranty and guarantee radon levels of 4.0 or below during that time frame.

On top of the warranty, we promise satisfaction, efficiency, property protection and respect for you and your home while we work.

Price Assurance Guarantee

We understand that you may want to have another contractor bid your project. Our goal is to have the best work done at a price that works for you, which is why we offer a price assurance guarantee when you choose to work with us. If another Better Business Bureau-registered contractor offers you the same scope of work at a lesser price within 30 days, we’ll match their proposal. If we can’t match or beat another company’s proposal for the same quality of work, we’ll return any deposits you may have paid. Learn more here.

Why Choose Thrasher?

In a word: experience — both as it relates to the expertise we’ve amassed over the years and the way we interact with our customers every day. Thrasher is a family-owned, family-run foundation repair company that has been providing foundation and basement repair solutions for more than 40 years. Over that time, we’ve grown from a single-person business operating out of a basement to a thriving enterprise of more than 200 employees providing foundation repair services to homeowners across four states.

We’re a member and sister company to the Supportworks network — a group of more than 130 contractors across the United States and Canada that is committed to redefining the industry by proving that more is possible when it comes to the homeowner-contractor experience. Honesty. Transparency. Courtesy. Respect. These are the values that drive us, from the person who first takes your call to the person who shakes your hand when the job is completed to your satisfaction.
