"Chris was WONDERFUL! I just purchased a home and wanted to have a mold inspection done for peace of mind. Chris took time to explain the process and put my fears at ease with his vast knowledge. He reviewed the test results with me prior to closing which gave me the peace of mind I needed to confirm I was making a good purchase and great investment. I highly recommend Mid Atlantic Commercial Residential Real Estate Solutions. VERY PROFESSIONAL AND COURTEOUS!!"

"I was very pleased with the service and work done by SWAT environmental. Lance was very helpful in explaining the process when he booked my appointment and the two techs who installed the radon remediation system were professional and courteous. The system itself isn't inconspicuous but I feel safer knowing that our radon levels are significantly lower now."

Radon Detection and Reduction questions, answered by experts

Radon enters your home when warm air begins to rise and exits through the roof, creating a vacuum that pulls cooler air from under the foundation. Part of that air is radon, which is an invisible, odorless gas that develops naturally when radioactive particles are deep within the ground. Those particles usually come from decaying matter in soil and rocks.

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.

The fan that pulls the radon out of the air needs to run continuously, so you may see an increase in your electric bill once you install the mitigation system. Additionally, you may see an increase in your heating or cooling bills, as the fan can cause some loss of hot or cool air.

The average radon mitigation system uses about 876 kWh of electricity per year, although the exact amount of electricity used will vary depending on the size of the radon fan. Once the system is installed, the annual increase to your energy bill could range from $30 to $300 per year, again depending on the size of the fan.

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.
