"We used Radon Abatement Services for our basement. The radon levels were slightly over the EPA recommended limit. We mitigated the radon as part of a larger basement renovation. Radon Abatement Services worked with our General Contractor and did a great job. Radon levels are vastly reduced now as a result of their work."

"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."

"You certainly get what you pay for! While CSI wasn't the cheapest on our list of home inspection and radon testing quotes, the cost was more than reasonable for the level of service that we received. Ron, our home inspector, was fantastic! He arrived early, and I don't think he could have been more thorough than he was! He was very friendly and personable, and was more than willing to answer our questions during the inspection. He went through the entire home with a fine toothed comb! He pointed out defects that he found, and explained things in detail. He also highlighted the positive things he found. Used a drone to inspect the roof and chimney, and thermal imaging to check for hidden moisture. I feel like we have an excellent idea of the condition of the property we are buying, which has done a lot in making us feel more comfortable! The report we receiced within 24 hours was professional and clearly written with appropriate photos attached. Will certainly recommend to others, and will use them for any future home inspection needs we have!"

Radon Detection and Reduction questions, answered by experts

If high radon levels are detected, steps include sealing entry points, installing a mitigation system, and retesting the air regularly to ensure reduced levels.

Mitigation can take several days depending on home setup, equipment accessibility, and achieving effective diffusion system sealed efficiency.

Keeping radon from getting into your home is much better than having to get rid of it once it's already indoors. While there may not be a way to fully prevent radon from getting into your home, there are things you can do to reduce the gas's ability to enter. 

Sealing foundation cracks and openings can help keep the gas from seeping inside. Improving air flow, such as by opening windows, can also be helpful. If you're building your home from scratch, talk to your contractor about using radon-resistant construction to keep the gas out.

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.

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