"Ted Riddick did an excellent job of performing a mold test in our basement, at the buyers request. I was very leary at first, because we recently cleaned the carpets and were concerned and/or confused that mold could be in our basement. We certainly would have known if we had mold in our basement or water coming causing a mold situation. Needless to say no mold was found, and my worries were alleviated. Mr. Riddick is a seasoned inspector, with a deep knowledge all areas of home inspections. He was professional, kind, did a great job."

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

"I called Atlantic Radon to see if they could replace a radon fan. Tommy called me back immediately. He sent Zack out on Monday to see what the problem was. On Tuesday Tommy and Zack came out to move and replace the old radon fan from the basement to the attic. Once they removed the fan, they discovered my sump pump needed to be replaced too. Tommy explained the process for both issues. They did not have a sump pump on the truck so they completed the job with the radon fan and scheduled another date for the sump pump. Tommy and Zack were professional, polite, arrived on time and answered all of my questions. I scheduled the sump pump repair and all went well. Now I have piece of mind knowing I am in a safe home. I would highly recommend Atlantic Radon! The price was very reasonable."

"Chris was WONDERFUL! I just purchased a home and wanted to have a mold inspection done for peace of mind. Chris took time to explain the process and put my fears at ease with his vast knowledge. He reviewed the test results with me prior to closing which gave me the peace of mind I needed to confirm I was making a good purchase and great investment. I highly recommend Mid Atlantic Commercial Residential Real Estate Solutions. VERY PROFESSIONAL AND COURTEOUS!!"

FAQs for radon gas testing projects in Clarksville, MD

Radon is the second leading cause of lung cancer in the U.S. The gas seeps through cracks in foundations and collects in basements and other low areas. Once you breathe it in, radioactive particles lodge in lung tissue and do long-term damage. Because you can’t see or smell radon, the EPA recommends testing your home every two years—and after major renovations—to keep your family safe.

Yes—every home should be tested. The EPA advises doing it at least every two years and any time you remodel, buy, or sell. On average, one in 15 houses nationwide sits above the recommended limit, and the only way to know where yours stands is a formal test. The equipment simply measures gas levels and won’t change your indoor environment, so the process is completely harmless.

Certified radon professionals—often home inspectors or dedicated radon mitigation contractors—handle testing. These radon testing professionals follow EPA protocols and use calibrated instruments to check levels throughout your house. Hiring a certified radon specialist means results you can trust for real estate deals, insurance requirements, and, most importantly, your family’s health.

Inspectors specialize in measuring radon gas levels, while licensed mitigation contractors design and install the systems that remove it. If your test comes back high, your inspector can point you to a qualified mitigation pro who will size and install the right fan, piping, or other equipment to bring levels down.

No—standard home air purifiers don’t touch radon. They’re built to trap dust and pollen, not radioactive gas. If testing shows high levels, you’ll need a dedicated mitigation system that vents the gas from beneath your home to the outdoors. Relying on a room purifier alone won’t keep your indoor air safe.

Opening a few windows in your home might dilute radon for a short time, but the gas seeps back in as soon as they’re closed. For a lasting fix, you’ll need a professional mitigation system—often a sub-slab depressurization fan—that pulls radon from beneath the foundation and safely vents it outside.
