"Radon Abatement services is a reliable dependable superb company. I have had an excellent experience from start to finish. Scheduling was easy and expeditious, service was professionally and very well done. Most importantly, Radon is gone with its in-house level reduced to almost its outside level. John Swett was very helpful and kindly answered all my emails and quickly addressed every concern I had. This project could not have been done better."

"Mr. Benner has been in business for 16 years and he still has the energy of a new business entrepreneur. He was recommended by the radon level testing company we secured to test our newly built home, which was completed in September 2014. Our levels were in the and quot;7and quot; level, only about 2x the level recommended for active remediation. According to Mr. Benner, he has remediated buildings with levels above 100 in the past. He was very professional, knowledgeable, punctual, flexible and informative. I highly recommend Mr. Benner and his company for your radon remediation projects.
He also provided as part of the remediation cost, a radon level detection kit with pre-paid postage to be sent to an evaluation company, the results of which were to be emailed back to me. Essentially, he provided a test-based assurance that his work met the standards he'd specified.

"The work has not yet been done - scheduled for two days from now. Very pleased with the estimate and service to date. The work has now been completed. An excellent job configuring the stacks to be as unobtrusive as possible, sealing cracks and floor drain, and installing a radon flow alarm. An independent radon test has been scheduled now that the work has been finished. Excellent company. Highly recommended."

"I was very pleased with the service and work done by SWAT environmental. Lance was very helpful in explaining the process when he booked my appointment and the two techs who installed the radon remediation system were professional and courteous. The system itself isn't inconspicuous but I feel safer knowing that our radon levels are significantly lower now."

"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've used their plumbing, and they're very expensive.? They get the job done, but they're very expensive.? The work was done at my husband's mother's house that he was putting on the market. They're good. They do the work, but they're just so expensive.? They're pretty good about time. Somebody calls you if they're running late.? I will use them again, because I have a contract with them.? They get the job done, but they're just outrageously expensive."

FAQs for radon gas abatement projects in Potomac, MD

The only way to know whether your home or water supply contains radon is to schedule a professional test. A qualified radon inspector will collect samples, deliver lab-verified results, and explain the findings for $150 to $800. Once you know your exact levels, you and your radon mitigation pro can choose the right system and tackle the problem before it affects your family’s health.

Both roles tackle radon, but they focus on different steps. Inspectors test your home, interpret the results, and determine whether levels exceed EPA guidelines. Mitigation pros design and install the system that lowers those levels. Some companies do both, but the skills and equipment differ, so always verify that the person you hire is properly certified for the specific service you need.

Installing a mitigation unit fixes radon problems by reducing indoor gas levels to established safe standards. A system designed and installed by a mitigation expert, tailored to your home's specific layout and foundation, guarantees effective radon reduction. This expert installation ensures consistent performance over time while safeguarding your indoor air quality.

Open windows and doors do not reduce radon levels because they trigger a pressure imbalance that draws radon-laden air into your home. This practice fails to control radon concentration and can even worsen the issue. An active suction mitigation system provides a proven, safe, and effective solution to reliably reduce radon levels.

Radon mitigation systems generally last between 10 and 30 years, depending on system type and maintenance. Passive systems endure the longest because they have no moving parts, whereas active systems, which use a fan, require fan replacement every 5 to 10 years. System components, such as PVC pipes, seals, and fittings, can remain effective for decades when paired with periodic inspections and proper maintenance.

Radon mitigation systems consume between 300 and 3,000 kWh of electricity per year, depending on fan size and system design. On average, an active radon fan draws 100 to 300 watts continuously, which translates to roughly 876 kWh annually, and adds $30 to $300 to your energy bill each year. Choosing a high-efficiency fan and ensuring tight sealing around pipes helps minimize these ongoing costs.
