"Ted Riddick did an excellent job of performing a mold test in our basement, at the buyers request. I was very leary at first, because we recently cleaned the carpets and were concerned and/or confused that mold could be in our basement. We certainly would have known if we had mold in our basement or water coming causing a mold situation. Needless to say no mold was found, and my worries were alleviated. Mr. Riddick is a seasoned inspector, with a deep knowledge all areas of home inspections. He was professional, kind, did a great job."

"<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 />"

"Buyers Eyes Home inspection did a great job on our pre-drywall home inspection. Almost every possible issue was caught. Brett was punctual and thorough. The multi page report had good pictures to help explain the issues that he found. Not every issue found could be fix by the builder because the recommendation was above the building code but most items were fixed. I'm really appreciative of the inspection that Brett did and look forward to the inspection he will do for me after my final is completed."

"I am in the process of house hunting and I have had Robert with RC Air & Mold Solutions conduct mold inspection and testing on two properties. Since I was exposed to toxic mold at my previous residence, Robert's knowledge and expertise were needed and appreciated. He fully explained his process, was prompt in completing his inspection, and followed up with both verbal and written reports. He was pleasant to work with and patiently addressed all questions. I highly recommend RC Air & Mold Solutions."

"If I could use only two words to describe Craig Kripas (owner) I would say trustworthiness and excellence. <br /> He and his workers (foreman Edmondo, and the other three) were hard working, honest, and did an incredible professional job for a fair price. They know their business, (Check out their website, it is educational, allowing you to read up and understand what Craig and crew are going to do to waterproof and make your home safe and healthy), and they do not cut corners on doing it correctly. <br /> I was married to a subcontractor for 18 years, and this is the first professional (Craig Kripas) whose work-ethic and excellence are comparable to my former husband's- who was without equal in his line of work: cabinetmaking and finish. <br /> BEFORE: Craig came and crawled through my crawlspace, took photos, uploaded them unto his laptop, and explained what needed to be done. He sent me an estimate that night via email. My crawlspace had cracks, leaking water, was moist, insulation was wet and falling down, the light plastic that the former owner had laid in the crawlspace was not taped at the seams, and had pools of water where the ground underneath it was not level. There was junk thrown in my crawlspace, no sumppump or electrical hook up, and mold. <br /> AFTER: Craig and crew were able to finish in 3 days, which was a window when the weather held out a little less than that time in early February. They  leveled the crawlspace ground, reinforced any floor supports that needed (in my 1938 bungalow), dug trenches and laid drain and installed the sump-pump, then went on to shovel and level rounded stone gravel (that does not puncture the 6 mil plastic overlay), to make it easy to crawl through. I went and inspected with Edmondo, and crawled through the crawl space. It was clean, dry, and even cozy, although a little clausterphobic for my taste. <br /> They dug window wells, and replaced the old ones, repaired the brick on the exterior around the window wells, repaired the brick around the entrance to the crawl space, built a new hinged hatch and installed it, graded the landscape so that the water ran away from my home, extended the downspouts, and probably a hundred other things that I didn't notice. <br /> OVERALL: I have never been more pleased with work done, as well as their polite, thoughtful approach. (I did not feel pressured in any way, Craig is soft-spoken, and explained and gave me choices on how he could fix the problem/ and costs per task, if I needed to do it in stages or only wanted to do the minimum).  <br /> Kraig Kripas and his crew are professional, trustworthy, do excellent work, and delivered beyond my expectations, which is a difficult thing to do. <br /> <br /> <br />"

FAQs for radon gas testing projects in Chewsville, 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.
