"Professional, punctual, knowledgeable, and honest. After I contacted him to hire him for testing he came by and offered to test, then explained how the radon level was low during warm weather. However I still wanted to test. When the test came back very low level, he offered to come back, and retest for free during the cold weather. I would definitely recommend this company to anyone needing Radon testing or mitigation."

"Brian was really friendly and professional, and you could tell he was very thorough. He explained everything in a way that was easy to understand during the inspection, and the report he sent after was super detailed with pictures and notes on all the systems in the home. I especially liked that he included a section that called out the main issues to focus on. Overall, we were very happy with his service and would definitely recommend him to anyone."

Radon Detection and Reduction questions, answered by experts

Radon is a cancer-causing radioactive gas that poses serious health risks, infiltrating homes through foundation cracks and unnoticed spaces.

No, radon mitigation systems do not decrease home value or make a home harder to sell. In areas where homes experience similar radon exposure risks, a radon mitigation system is viewed as an improvement. Potential homebuyers often opt to buy a home with a radon mitigation system already installed to reduce the risk of cancer for their families.

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.

Abatement includes sealing entry points and venting with systems that reduce radon levels below recommended EPA limits. It is handled by certified professionals.

Your radon mitigation system may be loud because it’s time to replace it. Any sounds are usually from the inline fan that helps create the vacuum and resulting airflow. If you hear a new, loud mechanical or humming noise from your radon fan, it might be time to replace it. Most fans used in radon mitigation systems last up to 10 years, but may need to be replaced sooner.
