"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."

Customers say: Quick response

"After my basement test come back with significantly elevated radon, I contacted radon abatement services at the recommendation of a neighbor. A day and a half later, they were on site. While performing the initial walk through, the experienced and thoughtful professionals adapted their plan to utilize my sump pump. This was an effective strategy as it addressed the main source of radon and concealed the system in completely unfinished space. I just received my post mitigation radon results, and the system is working phenomenally. To sum it up, I was blown away by the responsiveness, thoughtfulness, and reasonableness and can't say enough positive things about this company. I don't ever post reviews, but in this circumstance I absolutely had to."

"<p>I think I found them on Angie's List. They have been fantastic during our home renovation process. I keep putting them on hold, but I have built a relationship with them and they have been so patient and good throughout the whole thing. They have come out multiple times to help me with our previous contractor and current contractor for the remodeling. They have been great. They came out, met with my new contractor and it cost me nothing. They have been in constant contact with me regarding the status. They prepared for the states when I asked them to be ready to do the asbestos abatement. That was a part of the first stage of my remodeling project. Their pricing has been very reasonable. They did an assessment not just of the cost for the work, which they revised based on what the insurance company had told them to change. They have engaged with the insurance company, they have engaged with my remodelers and have come out without even charging us. The work that we have paid them for was just one time testing. This was the second test versus the first test we had. They do asbestos testing and asbestos removal.    </p>"

"I called Rodolfo on a Friday because my radon mitigation system (installed by a different company) was in need of repair. He was able to come by the next day, on Saturday morning, and quickly identified the problem and was able to fix it."

"Bob was on time, friendly, and extremely knowledgeable. He performed a thorough inspection of the home and conducted a radon test. He spent a lot of time talking with us and explaining his findings. He also helped us out after the inspection by providing information about building code and safety when the seller questioned if some of the requested repairs were required. <br /> I think he may be a bit more pricey than other inspection services (we paid $640 for inspection + radon test), but the value he provides is well worth the price. Would absolutely use him again in the future and recommend him without any reservations. Should also add that he accommodated our tight timeline and came out on a weekend with only a couple days notice. He's great! <br />"

"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. <br /> 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. <br />"

"Quite well. Greg Kemp, a registered professional engineer, conducted the inspection. Was extremely thorough and patiently answered, in depth, and in layman's terms, numerous questions from the new owner of the structure."

"I was fortunate to get an appointment with Robert the day after we spoke. I was looking for someone who is very good and has a sentrilock key card. He's the answer to my prayers. He sent me samples of home inspection report and pictures few minutes after we spoke. They were pretty impressive. My husband came on time at the house. He was already at the house and have started doing some work. He probably came 10-15 mins ahead of us. His experience speaks for the quality of his work. He is very thorough. He explained to us every single detail. He also gave us tips/recommendations and things that we should keep in mind. He puts red dots on the things that he noticed so it would be easy to spot and remember. He also put those cards and instructions for the valves. That's a huge help. It took him 3 hours to complete the inspection. He sent the reports in the evening the same day of the inspection. It was very detailed and has all the things he noticed/took note of. My husband and I were very happy with his work and how the inspection turned out. We also did the radon test btw."

FAQs for radon gas abatement projects in Rockville, 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.
