Customers say: True professional

"Jeremy was very professional and did a great job. He had reached out after I scheduled the original appointment to reschedule due to poor weather conditions. He offered to move the appointment to a date/time that he usually doesn t work to accomodate my needs. Once he had finished his work, he walked my fiance and I through everything explained it all very clearly. He also thoroughly explained the process for testing radon levels and getting test results back after the mitigation installation was complete. Would definitely recommend his services as he did a great job and his quote was very competitive."

Radon Detection and Reduction questions, answered by experts

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 cost to replace a radon fan ranges from $300 to $600 for the fan itself, with installation adding an additional $200 to $500. Overall, the total cost for replacement can range from $500 to $1,100, depending on factors such as the fan model, home size, and local labor rates. If the fan is part of a larger radon mitigation system, the price may be higher.

There are steps you can take as a homeowner to remediate radon yourself. While a radon reduction professional can make the biggest impact in your home, you can make efforts to improve radon levels on your own by sealing cracks, increasing ventilation, and testing for radon regularly.

While DIY testing is possible, abatement generally requires professional installation to ensure efficacy and meet safety standards.

The soil beneath your house is most likely what’s causing an increased level of radon. This is because soil holds radioactivity for a long time and it’s also what most buildings are built on. Another common source of radon is water from a source that hasn’t been through periodic radon tests, such as well water. Over time, the radon from the soil can inhabit other parts of your house like the foundation or plumbing.
