"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."

"<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 />"

"Robert was extremely informative and helpful during the inspection. He was willing to walk me through the process, explain what was happening, and educate me about mold and possible mold remediation options. Air samples are taken during this process that then have to be sent to a lab for analysis. This process took about 3 days and then I received an email with the lab report and a phone call from Robert to review the results. Luckily for us, mold levels were low enough that we are not going to seek professional remediation services. I would recommend RC Air & Mold if you are looking for an independent mold test. RC Air & Mold does not do remediation, so I felt that Robert's recommendations were not influenced in any way."

"Dave has inspected two properties for us now. He arrived early and inspected the roof before I arrived on both houses. He was extremely thorough, taking lots of pictures and checking everything. His reports have been available within one day and were very easy to understand and included photos, notes and what he thought we should budget to replace in the near future. Both inspections lasted almost 3 hours and uncovered enough major work that we backed out of the first one and are asking the sellers to complete the work on the second house he inspected, which we are now in contract to buy. The radon inspection took an extra day or two for results and cost about $125 I think <br /> Overall, Dave has been easy to get a hold of and easy to work with. He will give you his opinion or advice when you aren't sure what to do next. His experience in home-buying and contracting is very useful and he gave us many knowledgeable recommendations and even some price quotes which turned out to be accurate. It feels like having your  "Uncle Dave" inspect the house! We'll definitely recommend him to friends and we'd gladly work with him again in the future. <br />"

FAQs for radon gas testing projects in Sharpsburg, 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.
