"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."

"Once they started working on it, the work was great. What they did was good, but they forgot to put caulking on one of our skylights. They came back quickly to fix it. We put half the money down and then we didn’t hear anything for 4 months. I guess they were switching company owners, but since then it has been good."

Radon Detection and Reduction questions, answered by experts

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

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.

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.

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.

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.
