"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

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.

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

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 fan that pulls the radon out of the air needs to run continuously, so you may see an increase in your electric bill once you install the mitigation system. Additionally, you may see an increase in your heating or cooling bills, as the fan can cause some loss of hot or cool air.

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.
