"Hired for the convienience of their timely ability to install a radon system. The vent on the outside of the house is a large diameter, circular chimney that is very unsightly. Prices were a bit higher than other companies, but their ability to install quickly took precedence. In SWATs defense, I did not inform the company of my displeasure as the system was being installed as a condition of sale."

Radon Detection and Reduction FAQs, 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.

Ideally, no one will live in a house with elevated radon levels, as prolonged exposure increases the risk of serious health issues like lung cancer. However, homes with radon can be made safe through mitigation systems, such as active soil depressurization. Testing for radon regularly and addressing high levels helps ensure a safe living environment.

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.

Radon is a cancer-causing radioactive gas that poses serious health risks, infiltrating homes through foundation cracks and unnoticed spaces.
