"I scheduled the radon testing with Bill. He was very thorough and accommodating. Bill agreed to meet my real estate agent at the property to set up the testing equipment. As promised, the test results were provided in a report format and after 48 hrs. Great service."

"Jerry provided excellent service for our air mold test. He was prompt in scheduling the appointment and arrived at the property as planned. After conducting the test, we received the results in just two days, which thankfully turned out negative."

Hello my name is Jason William Hornung. Buying a home is a big investment. I want to help you make a well informed decision. I have been in the residential construction field for 17 years, and have an intimate knowledge of the homes in our area having done so much work in them myself. I stay continuously trained studying current information to give the best reports out there. I've seen many things that other inspectors have missed both as a home inspector and a contractor. My inspections meet or exceed the ASHI standards of practice. WWW.Homeinspector.org/standards WWW.JWHInspections.com

Radon Detection and Reduction FAQs, answered by experts

Yes, many systems include warranties for performance. Confirm terms with your installer.

While DIY testing is possible, abatement generally requires professional installation to ensure efficacy and meet safety standards.

Abatement includes sealing entry points and venting with systems that reduce radon levels below recommended EPA limits. It is handled by certified professionals.

No level of radon is technically safe, but since it is present everywhere, complete avoidance is impossible. The average radon level in homes across the United States is 1.3 picocuries per liter (pCi/L). The Environmental Protection Agency (EPA) recommends taking preventative measures if your home's radon levels are between 2 and 4 pCi/L or higher.

A homeowner can install a radon mitigation system on their own. But it’s a challenging DIY that requires a lot of knowledge about radon mitigation as well as familiarity with local regulations. You do not want to risk an improper installation that leaves the system unable to detect radon or gives it a shortened life span. Relying on a professional is the surest way to guarantee a successful installation.
