"Excellent Water/Well Testing Service from NextDay Inspect – Highly Recommend! I recently had a water/well test done by NextDay Inspect, and I couldn’t be more satisfied with the entire process. From scheduling the appointment to receiving the results, everything was seamless and professional. Sonya, the inspector who came out, was amazing. She was punctual, thorough, and took the time to explain the entire testing process. She made sure I understood what was being tested and why, which gave me confidence in the results. The whole experience was smooth and stress-free, and I really appreciated how well everything was organized. The results were delivered quickly, and NextDay followed up to make sure I had all the information I needed. I can confidently say that NextDay Inspect provides top-tier service, and I highly recommend them for anyone needing water/well testing."

"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."

"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."

"Excellent. GMD installed a system that was integrated into existing french drain, updated an existing sump pump, installed a duct fan, and sealed the entire system. They performed a smoke test to ensure air flow. Team took pains to leave behind a clean work area, were friendly, and willing to ask any and all questions. Radon following their test showed a significant drop in detected radon. Would highly recommend them to anyone requiring radon mitigation."

"I contacted Mitchell Home Inspections due to a positive referral from a friend. The inspector (Cliff) arrived early and was very knowledgeable and polite. He did a really thorough inspection and the report was well written with many pictures, notes, and findings. One of the most important things he did was to inform me that he observed radon mitigation systems on the surrounding homes. Based on this, I requested that he perform the radon test and we discovered that our home had a very high radon level. If he did not mention that, my family would be putting ourselves at risk for lung cancer (due to radon) without even knowing it. Now we have the mitigation system in place so we can sleep well and safe. THANK YOU CLIFF!!"

FAQs for radon gas testing projects in Rosedale, 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.
