"My only regret is not hiring Adam Contracting sooner. From the beginning of the project, I was updated on the schedule and cost. All of the employees were professional, and skilled, and left my house clean after each task. If I had issues or noticed something that needed to be changed the owner addressed the concern immediately. I am very happy with the finished project!"

"David from RHI does the most thorough & informative home inspection we’ve ever been part of. It was wonderful and educational to walk with him and see the inspection process. He did a wonderful job showing us the good and the bad, as well as teaching what to do and look for in the future! A truly exceptional 3 hours."

"I used this company to perform a home inspection before I bought my house. Due to its negligence and breach of contract, 9 months after I moved in, I had to replace the roof on the house. The company will do nothing to rectify the situation. They are cheats and liars that hide behind their contracts. Their inspectors take every shortcut, and they will not protect you during the home buying process. Just don’t use them."

"I have been a customer of Hedayat for well over 9 years, from the time his ad appeared in Angies List. He is an expert on all things carpets which means as an appraiser, in addition to the cleaning and repair services provided, the quality of the work is the best it gets. My carpets thanks to the care given, all continue to look as they did when I brought them back to the US from the Middle East 14 years ago. I highly recommend Art Connection to those members who are seeking expert evaluation of and care for their prized Oriental carpets."

FAQs for radon gas testing projects in Cheltenham, 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.
