"The structural/electrical/plumbing inspector was fantastic. He spent over 4 hours going through every inch of the home, provided immediate in-person feedback showing significant issues, and followed up <48 hours later (on a holiday weekend) with a 133-page report with pictures, thermal scans, etc. On a lesser note, the radon inspector showed for a few minutes during the structural inspection and set-up measurements in the basement. The report was issued quickly but I found out later that the radon inspector had not taken into consideration the attached (inaccessible) crawlspace that made up 25% of the lower structure. I found out from a radon remediation contractor that the state code required the radon inspector to measure levels on the 1st floor above the crawlspace in cases where the substructure could not be accessed. Overall, the huge amount of time the structural inspector put into the property was worth the A rating. Just watch the radon inspection if you have a strange basement set-up like the house I am purchasing."

"We received an asbestos inspection/test for our old plaster walls and ceiling areas. The turn around times were fantastic - inspector was in our area and able to fit us in the same day I called. Sample results and accompanying lab report were emailed within 36 hours. All samples were analyzed by a local lab accredited under the NIST NVLAP Asbestos Fiber Analysis Lab Accreditation Program, so I felt comfortable trusting the results. The inspector seemed very knowledgeable and helped walk us through any areas that could be of concern. Thankfully all samples were negative, but the modest inspection and sampling fees were well worth the piece of mind during our remodel. In short, I highly recommend this company for asbestos testing/inspections."

"Our existing system had been in the house 4 years and we had already had the fan replaced once. The previous company also used gutter pipe instead of PVC. We had Radon Experts come out to evaluate. Originally we were only going to replace the pipe since it was making so much noise that it was hard to sleep. Radon Experts told us that the type of fan that was being used was known for going bad and they recommended a different brand. It's been 3 months so far and no problem. They also replaced the pipe. They were quick efficient and very professional."

"Bob was on time, friendly, and extremely knowledgeable. He performed a thorough inspection of the home and conducted a radon test. He spent a lot of time talking with us and explaining his findings. He also helped us out after the inspection by providing information about building code and safety when the seller questioned if some of the requested repairs were required. <br /> I think he may be a bit more pricey than other inspection services (we paid $640 for inspection + radon test), but the value he provides is well worth the price. Would absolutely use him again in the future and recommend him without any reservations. Should also add that he accommodated our tight timeline and came out on a weekend with only a couple days notice. He's great! <br />"

FAQs for radon gas testing projects in Germantown, 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.
