"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."

"I used Vespene Radon Testing earlier this year and was very satisfied with the experience from start to finish. They were punctual, professional, and very knowledgeable on all things radon testing. Results came back quickly, which mattered to me as a parent of a young child. Having reliable data in hand promptly gave me confidence that our home was safe. I would definitely use them again for any of my radon testing needs ."

"Mitch, the owner, did the inspection himself. I can't even begin to heap enough praise upon him. He is very personable, friendly, and amazingly thorough. He was recommended to me by a friend who does high-end home construction. Mitch arrived early and spoke with the sellers, before they left, and asked about any hidden things he'd be likely to find. He took 3.5 hrs to cover every inch of the 2800 sq feet, from the top of the chimney to the far corner of the crawl space. He'd have taken longer, only because of his thoroughness, but the sellers were getting antsy about returning home. Our property is on well and septic. Mitch subcontracts the septic tank inspection, and the company he uses also deserves an A+. In addition to the home inspection, Mitch inspected our chimney, wood burning stove, well pressure flow, and did a pest inspection. He can also perform a radon test (we did not need) and a water quality test, on our well water (subbed to the same company that does the septic inspection). I followed Mitch everywhere, except for the roof and part on an unfloored attic. He was quick to point out things I can easily take care of myself, and offered suggestions on potential repairs. Things don't end when you get the final inspection report from Mitchell Home Inspections. Mitch is available to answer any questions, go over the report in more detail, and due to his extensive background experience, answer any contractor questions. I've already had the opportunity to recommend him to a few friends, in the short time since he inspected our home, and will continue to do so."

"Mr. Goldberg performed a radon test for me and did find that I had some moderate radon levels in my home. He's very efficient with what he does. He referred me to a guy named John Sweat to help me deal with the problem. I spoke with the guy and gave me a proposal but I have not heard from him in about a week and a half."

"Could not have been any better. The office was responsive on initial contact, promptly scheduled, Came out and gave a detailed estimate and discussed their plan with real project photos. Very thoughtful on Options and strategy where to run the piping in a 29 year old house with not easy access for piping run. Detailed info on radon provided. They also replaced and sealed the sump pump which the two other estimates did not even consider. The crew communicated in advance on job start time. Mike and Clayton arrived right on time and were extremely professional and considerate, COVID-19 precautions with masks at all times, and they were done in about 3 hours; (much faster than others which said 1.5 days!) Cleaned up thoroughly vacuum etc. and went over system with me in detail. Their truck was well maintained, orderly with every tool and pipe connector possible. I got three estimates on this job. They GMD were not the cheapest of the three but the ~10 percent premium was worth it and included sump pump replacement and independent inspector testing follow up. Others bidders were cheaper and or did not account for follow up testing and/or did not give me confidence In their solution or capability to choose the best solution not the easiest one or cut a hole in my roof! I don’t write up many reviews but this was an experience worth sharing. Highly recommend. You won’t be disappointed."

FAQs for radon gas testing projects in Edgewater, 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.
