"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."

"Adam Contracting did a wonderful job in a short period of time. This was a small job that took some experience to not crack the Corian. The workers were friendly and efficient. I would highly recommend them."

"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."

"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."

"Daniel performed radon testing and did a home inspection for a home we are purchasing. He was easy to contact and always quickly responded to our emails. He was very thorough with the inspection, encouraged us to ask questions, and explained everything he was doing. The day after the inspection, we received a detailed report (with pictures) that listed the discrepancies and suggested repairs. We received the radon test results 2 days later. Daniel was very professional and was great to work with. We highly recommend him for home inspections and would gladly use his services again. <br />"

"<p>it was superb! they easiest, hassle free Radon test in town, with extremely proficient people -- very knowledgeable and very people-friendly! they took their time to explain things on the phone to me before I committed. the test came back within 10 days or so -- via email. which is very convenient. it was very clear as it is, but I like talking through it and get advice. they were instantly available to discuss. they gave me future tips to keep on top of all things Radon related. </p> <p>I have to say that all this comes to be after 3 months of many back and forths with 3 other companies -- none of the other companies could be bothered to schedule a time, and those who did, never showed up.. many times over. I don't know why I was so patient with them and I wish had discovered Environmental Testing & Research Laboratories much sooner.</p> <p>Really highly recommend them!</p> <br />"

FAQs for radon gas testing projects in Round Hill, VA

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.
