"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."

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."

"I had a wonderful experience with Boston Environment & Contracting. They came out on a Saturday to give me a quote and to get samples for testing. The quote was very reasonable and included everything from the removal to the air testing to take place after the removal. I got the quote on Saturday, got the asbestos tests back that Tuesday, and they came to the house to remove it all on Wednesday. By Friday they had gotten the air quality tests back and were able to remove all the safety plastic. This entire job took less than a week. I was in constant contact with them - they called to update me often and were always available if I called with a question. I recommend them HIGHLY."

"Our existing system had been in the house 4 years and we had already had the fan replaced once. The previous company also used gutter pipe instead of PVC. We had Radon Experts come out to evaluate. Originally we were only going to replace the pipe since it was making so much noise that it was hard to sleep. Radon Experts told us that the type of fan that was being used was known for going bad and they recommended a different brand. It's been 3 months so far and no problem. They also replaced the pipe. They were quick efficient and very professional."

"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 />"

"Could not have been any better. The office was responsive on initial contact, promptly scheduled, Came out and gave a detailed estimate and discussed their plan with real project photos. Very thoughtful on Options and strategy where to run the piping in a 29 year old house with not easy access for piping run. Detailed info on radon provided. They also replaced and sealed the sump pump which the two other estimates did not even consider. The crew communicated in advance on job start time. Mike and Clayton arrived right on time and were extremely professional and considerate, COVID-19 precautions with masks at all times, and they were done in about 3 hours; (much faster than others which said 1.5 days!) Cleaned up thoroughly vacuum etc. and went over system with me in detail. Their truck was well maintained, orderly with every tool and pipe connector possible. I got three estimates on this job. They GMD were not the cheapest of the three but the ~10 percent premium was worth it and included sump pump replacement and independent inspector testing follow up. Others bidders were cheaper and or did not account for follow up testing and/or did not give me confidence In their solution or capability to choose the best solution not the easiest one or cut a hole in my roof! I don’t write up many reviews but this was an experience worth sharing. Highly recommend. You won’t be disappointed."

"It went very well. Paul the inspector was highly professional and very pleasant to work with. He took his time to thoroughly go through the house and answer any questions or concerns that we had. He went well above and beyond to make sure we were satisfied with the whole process. We would highly recommend Paul and Accurate home inspections for your home inspections because they really take it seriously and know that this is a lifetime investment. On a last note the gas was not turned on the day of inspection but the company came back two days later to make sure the whole process is done without no fuss this is what i call real professionals. Thank you Paul and Fred. A highly satisfied Customer."

FAQs for radon gas abatement projects in Gaithersburg, 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.
