"I wanted to have the fan for a Radon mitigation system installed in the attic area above my garage, but knew that access from my basement to the garage would require routing of the mitigation pipe above a dropped ceiling in the finished portion of my basement. Only two of the four companies that I'd contacted were willing to quote a garage attic fan installation, and SWAT Environmental's quoted cost was lower than that of their competitor. As a consequence, I suggested that SWAT send a representative to review my installation to ensure that the cost that they'd quoted for a garage attic fan installation wouldn't need to be adjusted. SWAT's representative, Jayme, arrived at my home at the scheduled time, reviewed the installation and agreed that a garage attic fan installation could be accomplished for the quoted price, but indicated that I'd have to call the office to schedule an appointment because his schedule (and those of other installers) was already booked. I called and was able to schedule an appointment for Jayme to perform an installation a couple of weeks later. Despite a later than expected arrival, Jayme was able to complete the majority of the installation (pipe routing, wiring and fan installation) before he had to leave. He returned to complete the installation (cover and seal the sump pump pit) about a week later when a second appointment could be scheduled. I initiated the post-mitigation Radon level test with the kit that had been left with me a week after the mitigation installation was completed and ran the test for five days. The report from the test lab indicated that the radon level in the "living space" area of my basement had dropped from a high reading of 8 pCi/L (in pre-mitigation tests) to 1.2 pCi/L and this post-mitigation value was confirmed by comparison with a Radon monitor that I'd purchased through amazon.com that indicated a "long-term average" of 1.24 pCi/L for the same five days. It's apparent that the Radon mitigation effort in my home was successful. I'd have no concerns about recommending SWAT Environmental to others for Radon mitigation."

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 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.

Mitigation reduces radon levels, protecting your health and complying with safety standards.

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

Ideally, no one will live in a house with elevated radon levels, as prolonged exposure increases the risk of serious health issues like lung cancer. However, homes with radon can be made safe through mitigation systems, such as active soil depressurization. Testing for radon regularly and addressing high levels helps ensure a safe living environment.
