We are family owned and operated providing award winning services since 1998.

"John and his team were life savers for us- literally! We had hired a different radon mitigation company (nationwide) and needless to say, their system did nothing! I have two little kids and was so frustrated with the levels staying high. I was looking for someone who could possibly repair the existing system which is how I came across radon abatement services. They had videos and pictures on their website, of all the wrong work that was done by contractors. I figured these guys know what they’re doing. And know they did! I had emailed John to tell him our situation and he got back to me and explained everything in detail. He told me what and why our house needed a different system. I had not given him a single penny and he was so gracious to share his expertise with me. Ofcourse, Eventually we hired them to install a new radon mitigation system in our house. Within the day of installment, our levels went down below 4 and have stayed below 2 consistently thereafter. I cannot thank John enough. Their prices were also reasonable. I would give them 10 stars if I could."

FAQs for radon gas testing projects in Lexington Park, 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.
