"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."

"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."

"Mr. Goldberg performed a radon test for me and did find that I had some moderate radon levels in my home. He's very efficient with what he does. He referred me to a guy named John Sweat to help me deal with the problem. I spoke with the guy and gave me a proposal but I have not heard from him in about a week and a half."

"I contacted Mitchell Home Inspections due to a positive referral from a friend. The inspector (Cliff) arrived early and was very knowledgeable and polite. He did a really thorough inspection and the report was well written with many pictures, notes, and findings. One of the most important things he did was to inform me that he observed radon mitigation systems on the surrounding homes. Based on this, I requested that he perform the radon test and we discovered that our home had a very high radon level. If he did not mention that, my family would be putting ourselves at risk for lung cancer (due to radon) without even knowing it. Now we have the mitigation system in place so we can sleep well and safe. THANK YOU CLIFF!!"

"Mr. Glenford Blanc inspected my home.  Mr. Blanc arrived and immediately got to work.  He inspected the home and then walked me around and pointed out all the issues that he found.  He was very thorough in his explanations and took his time to make sure I understood what the problems were and how best to resolve them.  For example, the home he inspected was built in 1973 and still had an electrical circuit box that was no longer up to code.  He explained the problem and the history of the issue, which allowed me to do some additional research so that I could understand the nature of the problem.  The inspection took about 3 hours.  He inspected the external/internal components of the home and the roof, which was a major concern of mine.  He also gave me an idea of what issues needed immediate repair (safety hazards) and pointed out major system components (HVAC, compressor, etc.) that would probably need to be replaced in the near future.  This helped me determine if I could really afford the home and the repairs that would probably be needed w/in the first year in the property.   <br /> I appreciated that he took his time and didn't seem rushed or hurried to move on to the next property.  Also, the customer service was excellent.  I was quoted an incorrect price by one of ProSpex phone reps and they honored the price I was quoted.  Although they seemed to be a little more expensive than some of the other inspectors I researched, I felt I got a really thorough inspection and will use them again. <br />"

"They were very prompt, professional and did an extremely thurough job with the inspection. The price was reasonable and well worth it for the services provided. It was helpful to have a list of things to repair to send to the seller, and also for us to take care of in the next few months. We also added on a radon test for an additional charge."

FAQs for radon gas abatement projects in Baltimore, 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.
