One of the most neglected and unassuming areas of the home is the crawl space.

By installing vapor barriers, thermal insulation and dehumidifiers, you can turn you dirty, unsafe crawl space into a healthy, energy-efficient space. 

Signs of a crawl space problem:

  • Sagging floors
  • Condensation
  • Mold
  • Wood rot
  • Foundation cracks

Reliable radon testing and mitigation

In addition to our basement, crawl space, foundation, and concrete services, Thrasher can also test and remove radon from your home. Radon is a dangerous gas that develops from the decay of uranium in the soil below your home. Responsible for over 20,000 deaths a year in the US, it's crucial that you make sure you have a radon mitigation system installed if you're in need of one. Public building like schools have been involved in major radon projects over the past few years, so you should make sure your primary living space is safe as well!

Thrasher has the tools and expertise to get your project done the right way the first time. Our friendly, knowledgeable staff and certified technicians use only high quality products and are ready to help you find a solution that will work for you and your home. Call us today for a free estimate!
