"I would definitely recommend this company to anyone!!! I hired them and the job was done nicely, Dan O'Brien was the technician who took care of the project and he did an excellent job, he answered all of my questions and explained to me everything related to Radon gas. When he finished setting everything up and the job was completed all the working area looked super clean and the installation looks just like it is part of the house and that has been there forever. This is what I call a Perfect and Complete execution of a Radon gas mitigation project."

Radon Detection and Reduction questions, answered by experts

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).

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.

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

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.

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.
