"John and his team have the upmost professionalism, and we are extremely satisfied with the result of our radon mitigation system installed in our lower level. John was patient with me as we communicated on possible installation locations and was able to address all of our concerns. The crew provided excellent customer service. The supervisor discussed all of the possible installation options so I could make an informed decision on where to install the system. Our radon was averaging about 7.5 over 30 days, and would peak to 20-30 during heavy rain. Since our system has been installed and running, we've averaged 0.84 - and that's during heavy rain. Lastly, the total cost was fair and a great value for the price. I've dealt with multiple sub-contractors on various projects, and this was one of the better - if not best - experiences. I highly recommend this company if you're considering a radon mitigation system."

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."

"They were polite and quick to get the work done. The first installation was not sufficient to reduce the radon levels but they came out a second time, free of charge, to make the necessary changes. The final result was more than satisfactory."

Radon Detection and Reduction FAQs, answered by experts

The average radon mitigation system uses about 876 kWh of electricity per year, although the exact amount of electricity used will vary depending on the size of the radon fan. Once the system is installed, the annual increase to your energy bill could range from $30 to $300 per year, again depending on the size of the fan.

The lifespan of a radon mitigation system depends on the type of system and its maintenance. With proper care, a system can last for many decades. Passive systems tend to last longer as they have fewer components that require replacement. Active systems, which have more moving parts like fans, generally have a shorter lifespan. For instance, water filtration devices and active pressurization systems require more frequent maintenance. While the system as a whole is durable, the radon fan in an active system typically has a lifespan of 5 to 10 years and will need to be replaced. As long as the fan is working, the mitigation system should function correctly.

Installing a mitigation system reduces radon levels, which can cause lung cancer, providing peace of mind and long-term health benefits. It can also increase your home’s value, as many buyers prefer properties with radon safety measures in place. The investment is relatively low compared to the potential health risks associated with prolonged radon exposure.

Testing every 2-5 years or upon adjusting occupancy or structural changes maintains safe environments.

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