"Had them come out to install a Radon Mitigation Fan. Service was fast and the installer was extremely knowledgable. He was in an out within an hour and the radon dropped from a 4 to a 0.59! Extremely happy with the result. Price wasn't cheap by any means but definitely fixed our problem."

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.

The soil beneath your house is most likely what’s causing an increased level of radon. This is because soil holds radioactivity for a long time and it’s also what most buildings are built on. Another common source of radon is water from a source that hasn’t been through periodic radon tests, such as well water. Over time, the radon from the soil can inhabit other parts of your house like the foundation or plumbing.

Mitigation can take several days depending on home setup, equipment accessibility, and achieving effective diffusion system sealed efficiency.

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.

Options include sub-slab depressurization, crawlspace ventilation, and sealing cracks. Choose based on home construction and radon levels.
