"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."

"We were able to schedule an appointment with Mr. Lindsay on very short notice. I called him on a Friday and was able to schedule an inspection with him for the following Monday. He was punctual, polite and professional. He welcomed us to follow him around during the inspection and ask questions. He was also receptive to hearing our particular concerns about the home and addressing those concerns in his report in addition to his findings. Before leaving the home, Mr. Lindsay took the time to review his list of issues with the home with us to make certain nothing was missed for his final report. He completed and sent us the report very quickly (within 24 hours). The report was neat and detailed with pictures clearly illustrating any/all issues with the home. His work was also very affordable. I would definitely recommend him to a friend or family member in the future."

Radon Detection and Reduction questions, answered by experts

Your radon mitigation system may be loud because it’s time to replace it. Any sounds are usually from the inline fan that helps create the vacuum and resulting airflow. If you hear a new, loud mechanical or humming noise from your radon fan, it might be time to replace it. Most fans used in radon mitigation systems last up to 10 years, but may need to be replaced sooner.

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.

Testing every 2-5 years or upon adjusting occupancy or structural changes maintains safe environments.

Options include sub-slab depressurization, crawlspace ventilation, and sealing cracks. Choose based on home construction and radon levels.

The soil beneath your house is most likely what’s causing an increased level of radon. This is because soil holds radioactivity for a long time and it’s also what most buildings are built on. Another common source of radon is water from a source that hasn’t been through periodic radon tests, such as well water. Over time, the radon from the soil can inhabit other parts of your house like the foundation or plumbing.
