"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."

"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!"

"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.
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.

"The work has not yet been done - scheduled for two days from now. Very pleased with the estimate and service to date. The work has now been completed. An excellent job configuring the stacks to be as unobtrusive as possible, sealing cracks and floor drain, and installing a radon flow alarm. An independent radon test has been scheduled now that the work has been finished. Excellent company. Highly recommended."

Radon Detection and Reduction questions, answered by experts

Installation typically takes 1-2 days, depending on the system and property layout.

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.

If high radon levels are detected, steps include sealing entry points, installing a mitigation system, and retesting the air regularly to ensure reduced levels.

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.

A homeowner can install a radon mitigation system on their own. But it’s a challenging DIY that requires a lot of knowledge about radon mitigation as well as familiarity with local regulations. You do not want to risk an improper installation that leaves the system unable to detect radon or gives it a shortened life span. Relying on a professional is the surest way to guarantee a successful installation.
