"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 FAQs, answered by experts

You'll need to test your home for radon after installing the mitigation system, then again every two years. If radon remains elevated, contact a licensed radon professional, either the contractor who installed the system or a different one, and have them evaluate the system. They may need to make some changes to improve its effectiveness and performance.

Keeping radon from getting into your home is much better than having to get rid of it once it's already indoors. While there may not be a way to fully prevent radon from getting into your home, there are things you can do to reduce the gas's ability to enter. 

Sealing foundation cracks and openings can help keep the gas from seeping inside. Improving air flow, such as by opening windows, can also be helpful. If you're building your home from scratch, talk to your contractor about using radon-resistant construction to keep the gas out.

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.

Your radon fan needs to operate 24/7 to be effective. The only time the fan isn't operating is during its replacement. Radon levels in the home can increase within hours if the fan stops working or something obstructs the stack vent. Fortunately, radon systems require no downtime maintenance between fan changes.
