"I scheduled the radon testing with Bill. He was very thorough and accommodating. Bill agreed to meet my real estate agent at the property to set up the testing equipment. As promised, the test results were provided in a report format and after 48 hrs. Great service."

"D&H Demolition quickly demoed the carpet from my living, dining , and steps to the second floor. Replaced with re- claimed hardwood flooring which resulted in a significant cost savings for me. Replaced the flooring and steps with a satin finish that so beautiful that I keep getting comments. Work was timely completed and professionally done. I would definitely use their services again.

Hello my name is Jason William Hornung. Buying a home is a big investment. I want to help you make a well informed decision. I have been in the residential construction field for 17 years, and have an intimate knowledge of the homes in our area having done so much work in them myself. I stay continuously trained studying current information to give the best reports out there. I've seen many things that other inspectors have missed both as a home inspector and a contractor. My inspections meet or exceed the ASHI standards of practice. WWW.Homeinspector.org/standards WWW.JWHInspections.com

"Tommy, Paul and crew did an excellent job with my radon remediation and installation of a new attic stairs. They tailored the exhaust piping for my radon removal so the only thing that showed was the exhaust vent, which they painted to blend in with the roof. The test results after remediation was only 0.4 pCi/l. The very low results is a testimony for their outstanding work. They were very friendly and accommodating. They always strived to exceed my exceptions, which they did. I highly recommend Atlantic Radon."

"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.

Radon Detection and Reduction questions, answered by experts

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

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

Yes, many systems include warranties for performance. Confirm terms with your installer.

Radon is present almost everywhere but, like sunlight, the concentration levels and how often you are exposed to it have a large part to play in just how dangerous it is. There are levels of radon that are acceptable inside a house, but above a certain limit, radon becomes a serious radioactive hazard that is a known cause of lung cancer. In fact, radon exposure is the number two leading cause of lung cancer (after smoking).

There are steps you can take as a homeowner to remediate radon yourself. While a radon reduction professional can make the biggest impact in your home, you can make efforts to improve radon levels on your own by sealing cracks, increasing ventilation, and testing for radon regularly.
