Customers say: Quick response

"Scott was completely professional and very thorough with the inspection. He was very accommodating to the schedule which kept changing and being postponed due to issues with the seller getting the premises ready for an inspection (absence of heat and water). He even went back much later to complete the inspection once the water had been turned back on at the house. Explained what he was doing and what needed to be looked out for. I would not hesitate to recommend him."

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.

If your home has a sump pit, you can integrate it with a radon mitigation system. You can accomplish this by sealing the pump cover with an airtight lid that accommodates radon vent pipes and sump pump hoses. This allows the vent pipe to redirect the radon gas outside of your home.

Options include sub-slab depressurization, crawlspace ventilation, and sealing cracks. Choose based on home construction and radon levels.

Yes, many systems include warranties for performance. Confirm terms with your installer.

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.
