"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."

"Ryan was right on time both for the dropoff and pickup for doing a Radon test of my basement. He's a great communicator and is very personable! He was able to give me a fair assessment of the test results this time, how they related to the results I had gotten at closing of my home, giving me all the info necessary to feel comfortable on my plan of action. I would highly recommend him!"

"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!"

"JT of Dragon Ridge performed a Home Inspection and Radon Testing of a SFH in Fairfax, VA. JT arrived before I did, and was already examining the exterior of the property. While we waiting for my realtor to arrive, he grabbed a ladder and did a complete inspection of the roof (not all inspectors do this). Once we got inside, he explained the processes and we began. I shadowed him throughout the whole processes, and it was a wonderful experience. He was very thorough and knowledgeable, and was always willing to provide complete and educational answers about both the good and the bad he found. We got the report later that evening, and it was well written, with plenty of pictures of any deficiencies. He also performed a Radon test, and reported the results a few days later. I spoke to him over the phone about the findings, and he was able to discuss in detail the methodology he used, and the meanings of the testing numbers. Overall, I would highly recommend JT and Dragon Ridge."

Radon Detection and Reduction questions, answered by experts

The cost for a radon mitigation system typically ranges from $800 to $1,500, with an average around $1,000. The final price depends on several factors, including the size of your home, the severity of the radon issue, and the type of system required. Your home's foundation type also significantly impacts the cost. For example, sealing and ventilating an unfinished basement might cost around $4,600, while encapsulating a crawl space without a foundation slab can range from $1,500 to $15,000.

You can vent radon out of your house sometimes by simply opening a window, but it won’t remove the source, and will likely rise above recommended levels quickly. A professional will be needed to assess your home, and determine the best strategy for radon removal. Active radon sump pumps and soil depressurization systems are often used to forcefully vent the radon from your home.

Use a radon test kit or hire professionals to conduct a detailed assessment of radon levels in your home.

While DIY testing is possible, abatement generally requires professional installation to ensure efficacy and meet safety standards.

No level of radon is technically safe, but since it is naturally present everywhere, it is impossible to avoid entirely. The average radon level in homes across the United States is 1.3 picocuries per liter (pCi/L). The Environmental Protection Agency (EPA) recommends taking action to reduce radon levels if your home's test results are between 2 and 4 pCi/L or higher.
