"Dave first off cares about his customers health and well being. He is interested in solving your Radon issue and making sure the work is high quality. He pulls proper permitting for electrical and his support team is awesome. The other Radon company that was used did not meet specific standards in doing Radon migitgation work. Do your homework and read reviews before hiring a Radon company and check certifications: https://nrpp.info/. Dave takes his profession seriously and has a tremendous background in this work. I highly recommend Advanced Radon Technologies."

Radon Detection and Reduction questions, answered by experts

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.

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

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.

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.

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.
