"Jeff and his folks were a pleasure to work with. His communication regarding any delays or other issues is excellent. He is also great at answering followup questions that I have about how the system is running. It took our radon readings down to nearly zero from an alarmingly high value. We were hovering below 4 pCi for many years, but then our crawlspace was sealed and insulated and it soared in the living space. (The crawlspace itself was 20 pCi). Highly recommend."

"Found on Home Advisor, responded quickly after I reached out. Hired to install radon mitigation. Without asking....He took his shoes off once he saw we did. Cut could not have been any cleaner thru the laundry room tile and 4-6" of concrete subfloor, he didn't even break the tile! Took about 5-6 hrs to install. Post radon test came in at 0.3. Previously between 4-10. Worth every penny of the investment. You can't put a price on your health. Now we can breathe easy! Thank you Tyler Lucas!"

"The energy audit surfaced some significant issues. That's what we wanted. Shelter Alternatives presented a bid for the job, which seemed high. We are checking with other contractors to complete the work."

Radon Detection and Reduction questions, answered by experts

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.

Mitigation reduces radon levels, protecting your health and complying with safety standards.

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.

Your radon fan needs to operate 24/7 to be effective. The only time the fan isn't operating is during its replacement. Radon levels in the home can increase within hours if the fan stops working or something obstructs the stack vent. Fortunately, radon systems require no downtime maintenance between fan changes.

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.
