Radon Detection and Reduction questions, answered by experts

A homeowner can install a radon mitigation system on their own. But it’s a challenging DIY that requires a lot of knowledge about radon mitigation as well as familiarity with local regulations. You do not want to risk an improper installation that leaves the system unable to detect radon or gives it a shortened life span. Relying on a professional is the surest way to guarantee a successful installation.

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.

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 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.

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.
