"I couldn't have asked for a better experience. I checked a few Radon companies and Certified Radon was the best. They seemed to be the most knowledgeable, had the best warranty/guarantee, and actually came in cheaper than some of the others. They brought my radon level from a mid-6 to less than 1 on the first test. If you need radon services I would highly recommend."

"I had them come and give me an estimate. Josh was very professional and respectful. He gave me a written estimate right away. I would love to get the work done but cannot at this time because it cost too much and I am on fixed income. They will be the first I will contact should I decide to have the asbestos removed."

Radon Detection and Reduction FAQs, 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.

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

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.

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.

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.
