"I used Radon Abetment Services LLC to install a radon system in my basement. John and his team were excellent and I highly recommend them to anybody with this need. John was able via video over phone identify where the system should go. His team was extremely professional and courteous. The installation took a day and the improvement in radon levels was remarkable. We would absolutely use them again."

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."

"Ryan was right on time both for the dropoff and pickup for doing a Radon test of my basement. He's a great communicator and is very personable! He was able to give me a fair assessment of the test results this time, how they related to the results I had gotten at closing of my home, giving me all the info necessary to feel comfortable on my plan of action. I would highly recommend him!"

Radon Detection and Reduction questions, answered by experts

Ideally, no one will live in a house with elevated radon levels, as prolonged exposure increases the risk of serious health issues like lung cancer. However, homes with radon can be made safe through mitigation systems, such as active soil depressurization. Testing for radon regularly and addressing high levels helps ensure a safe living environment.

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

You can vent radon out of your house sometimes by simply opening a window, but it won’t remove the source, and will likely rise above recommended levels quickly. A professional will be needed to assess your home, and determine the best strategy for radon removal. Active radon sump pumps and soil depressurization systems are often used to forcefully vent the radon from your home.

The cost to replace a radon fan ranges from $300 to $600 for the fan itself, with installation adding an additional $200 to $500. Overall, the total cost for replacement can range from $500 to $1,100, depending on factors such as the fan model, home size, and local labor rates. If the fan is part of a larger radon mitigation system, the price may be higher.

Keeping radon from getting into your home is much better than having to get rid of it once it's already indoors. While there may not be a way to fully prevent radon from getting into your home, there are things you can do to reduce the gas's ability to enter. 

Sealing foundation cracks and openings can help keep the gas from seeping inside. Improving air flow, such as by opening windows, can also be helpful. If you're building your home from scratch, talk to your contractor about using radon-resistant construction to keep the gas out.
