"We had a special situation, and Epic was the only company willing to come out to help us evaluate the best location for installation. Installer was great - he recognized asbestos tile on the basement floor, and recommended appropriate remediation service. System is basically invisible - no ugly pipe up the outside of the house! Follow-up test shows radon level reduced to well under recommended minimum."

"SWAT did a great job installing the radon mitigation system in my house. They were very responsive, coming out quickly to provide a quote and offered a discount if the neighbors in the connecting townhouse would sign on as well. Installation was quick and the system was installed with no problem whatsoever. The radon levels in my house dropped from a reading of 12 to “undetectable” in just a couple of weeks."

"I hired Double Check to do an inspection for a personal decision of "Repair or Replace". Justin came out, performed the inspection, took photographs and answered all my questions. He found some issues like a few shingles missing, popped nailheads and the like. We discussed the Repair or Replace decision. Very knowledgeable and easy to deal with. Highly recommended."

Radon Detection and Reduction questions, 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.

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.

Mitigation can take several days depending on home setup, equipment accessibility, and achieving effective diffusion system sealed efficiency.

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.

You'll need to test your home for radon after installing the mitigation system, then again every two years. If radon remains elevated, contact a licensed radon professional, either the contractor who installed the system or a different one, and have them evaluate the system. They may need to make some changes to improve its effectiveness and performance.
