"<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 />"

"The home inspection was conducted on a house we had just placed under contract. Our Realtor highly suggested having the inspection done and recommended Realty Inspection Group. We obtained a quote in advance for the inspection and found the cost to be quite reasonable ($460 including a Radon test and cash discount) considering the various aspects and required knowledge base involved. We had prepared ourselves by researching what should be included in a home inspection on the internet and had even printed out a checklist to make sure everything was covered. We didn't need our checklist though as it was quickly apparent that Jason, a former home construction company owner, knew his trade well. Jason was punctual and very pleasant, taking the time to answer any questions we had and to discuss any preliminary findings. We were only aware of a couple of potential problems before he started. During his extensive three hour inspection he identified almost a dozen issues that needed to be repaired or replaced! Among other things, Jason inspected the roof, chimney, fireplace, attic, gas furnace, ducts, windows, doors, lights, home exterior, deck, patio, plumbing, floors, interior walls, appliances, outlets, electrical grounding system, and even took a breaker panel apart to inspect the back side of one breaker that had exhibited some charred wiring! The day after the inspection we received a thorough and very professional 14 page report with photos that documented all discrepancies found. Jason reminded us that while he had inspected the home initially, he was always there should we need any further assistance or have any other questions concerning the house as long as we owned it. He has already assured us he will participate in the final walk through to assure all issues were properly resolved at no additional fee. We were extremely pleased with Jason and the services provided and consider the money well spent. We highly recommend Realty Inspection Group to all."

"Tony from Pillar to Post was an excellent inspector. He showed up ahead of time and spent 5 whole hours (no exaggeration) looking at the exterior and the interior of the house in great detail while providing expert explanations with a patient and friendly manner to the uninitiated. He produced a detailed and readable report with the main points separated from the minor ones. He even offered to answer questions that we may have long after the inspection. I would recommend Tony and Pillar to Post to anyone who is interested in having a reliable and thorough house inspection. <br />"

"I had a sump pump system installed in the Spring of 2016. The installation went smoothly and the system was tested and worked fine. A few months later, prior to leaving on a vacation, I tested the system by filling the sump basin with water. Water sensor did not work and pump did not come on. I called B-Dry and they came out and installed a new sensor and switch. Installation now works fine. Very satisfied with the level of service from B-Dry."

"The report I was given was thorough and accurate. It was exactly what I needed to make an informed decision on the house I was purchasing. If not for them I would have missed a ton of things that needed to be done asap. I would have lost so much money after purchase. Also having the mold test and radon tests done gave me peace of mind. The house had mold! Glad I had it tested."

FAQs for radon gas testing projects in Salem, 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.
