"Scott Bacon of Certified Radon Systems, LLC is the best! If you need radon mitigation, I highly recommend Scott Bacon and Certified Radon Systems, LLC. We saw a mansion for sale in another state online and bought it. Of course, there are lots of things to fix up with the new house, including radon mitigation. Before we even set foot in the house, Scott evaluated the property and set up a mitigation plan. He worked with us remotely, so we didnâ  t have any extra costs of flying out to the new home before we were ready to move. And he installed the equipment on time and without a single problem. Scott also followed up after the install and did some testing to make sure the systems worked properly. The house is enormous, but the cost for the mitigation systems was extremely affordable. Scott Bacon and Certified Radon Systems, LLC were ultra-reliable and did a fantastic job! If you need radon mitigation, use Certified Radon Systems, LLC. Youâ  ll get excellent customer service and peace of mind knowing you are working with professionals to safeguard your home."

"He was on time, arrived at 9am as quoted and began to install the system. The system required two suction points and a sump pit cover. The sump pit originally had a pedestal pump in place and none of the other radon companies would change the pedestal pump to a submersible pump as required for the mitigation system to function properly. Rhino Radon not only changed the pump but installed a back flow check valve to ensure proper functioning of the system. All of the other companies said we would have to employ a plumber or a handy man to get this done. Had we gone that route the closing would not have happened. Rhino Radon gladly did all the work required and didn't even break for lunch!!! He was more concerned with getting us out of the vacant house seeing we are already down the cape. The system that involved a crawl space and being vented through the garage roof was completed immaculately and the test results came back at 0.5 pCil/L. This pleased the lender and buyer and exceeded our expectations. We highly recommend Rhino Radon Services.

"We are so glad that we selected CMM to do our mold remediation. From the initial meeting with Ken to the actual remediation by Ed and AJ, it was obvious that they are a family owned company who did the job in a caring and professional manner. Ed and AJ were always on time, courteous, informative of each step that they wee taking and at the end described what they did and why. I would highly recommend this company."

Radon Detection and Reduction FAQs, answered by experts

Use a radon test kit or hire professionals to conduct a detailed assessment of radon levels in your home.

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.

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.

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.

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.
