"Mike, of MCL, made an appointment to review the project and showed up on time. He is very knowledgeable and clearly went over all technicalities needed to take care of our radon gas problem. The next day he sent a quote. The job was finished on time at the quoted price, work was very professional and neat. I would definitely recommend MCL to complete mechanical work of this nature."

"SWAT did a great job installing the radon mitigation system in my house. They were very responsive, coming out quickly to provide a quote and offered a discount if the neighbors in the connecting townhouse would sign on as well. Installation was quick and the system was installed with no problem whatsoever. The radon levels in my house dropped from a reading of 12 to “undetectable” in just a couple of weeks."

Radon Detection and Reduction questions, answered by experts

Radon is the number one non-smoking cause of lung cancer in the United States, but it can cause some other concerning side effects in the meantime. If you have a raspy voice, chest pains, trouble breathing, difficulty swallowing, or any of the above, don’t hesitate to perform radon testing and install a mitigation system as soon as possible.

Many radon fans carry a five-year manufacturer's warranty. That said, your radon fan should last between five and ten years. Regular inspections will ensure the fan is operating properly. Unusual or exceptional noise coming from the fan or indications on your manometer or system monitor can immediately tell you that something is amiss.

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.

You can vent radon out of your house sometimes by simply opening a window, but it won’t remove the source, and will likely rise above recommended levels quickly. A professional will be needed to assess your home, and determine the best strategy for radon removal. Active radon sump pumps and soil depressurization systems are often used to forcefully vent the radon from your home.

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.
