"The installer (Davis) arrived on time, installed the system in about two hours, and showed me everything I needed to know about the system. The “before”and “after” test results were right in line with my own test measurements, which I took with a portable radon detector. The radon level dropped to a safe level after the system was installed, and that level has been maintained since it was installed in July of 2020, about 10 months ago. Overall, I was extremely pleased with A & R and I highly recommend them for radon mitigation work."

"Water Flo is fantastic. From Nick Sunday who did the walk through and estimate to the office staff and the installers, all are professional and friendly. No waiting months for the work to get done. The entire process took less than 2 weeks. Everyone was on time. The installation was neat and clean. The explanation of the equipment was presented so it was easy to understand and the radon system installed has dropped my levels 3 units!"

Radon Detection and Reduction questions, answered by experts

The cost for a radon mitigation system typically ranges from $800 to $1,500, with an average around $1,000. The final price depends on several factors, including the size of your home, the severity of the radon issue, and the type of system required. Your home's foundation type also significantly impacts the cost. For example, sealing and ventilating an unfinished basement might cost around $4,600, while encapsulating a crawl space without a foundation slab can range from $1,500 to $15,000.

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.

No, radon mitigation systems do not decrease home value or make a home harder to sell. In areas where homes experience similar radon exposure risks, a radon mitigation system is viewed as an improvement. Potential homebuyers often opt to buy a home with a radon mitigation system already installed to reduce the risk of cancer for their families.

Radon detection is crucial as prolonged exposure to radon gas, a leading cause of lung cancer, poses significant health risks in residential environments.

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.
