How Much Do Radon Mitigation Systems Generally Cost?

If you have found high radon levels in your home, you will need to take action as quickly as possible. The best way to do this is by installing a radon mitigation system. All homes should include this important safety device, as radon can negatively impact a building’s inhabitants. However, before installing radon mitigation systems, homeowners may wonder how much they generally cost since the installation can be a significant undertaking.

How Much Do Radon Mitigation Systems Cost?

Typically, radon mitigation systems cost anywhere from $800–$2,000, with the national average costing homeowners around $1,000. While these systems can be costly, they will protect you from the harmful health effects of radon gas, making them absolutely worthwhile.

What Factors Impact the Cost?

  • Home size: If you have a larger home, your radon reduction needs might be more extensive and pricier.
  • Foundation type: If your home has a crawl space, you must seal and encapsulate it, which can make the overall process more expensive.
  • Installation location: The location where your system piping reaches your home's foundation, whether it is a sump pump or a brand-new access point, can impact the installation price.
  • Ventilation system: If your home needs more adequate ventilation for proper mitigation, this can raise the cost.

Ongoing Costs and Maintenance

Energy Cost

Typically, operating a radon mitigation system costs around $100 per year, which will be reflected on your utility bills. Since the system is continuously operating, this price will be mostly consistent month to month depending on the system’s wattage and your area's energy cost.


While radon mitigation systems can last for decades, you will need to inspect and update certain pieces of equipment. Radon mitigation fans, one of the system's key devices, will last between 5 and 20 years. Replacing your fan will cost anywhere from $150 to $400.

Regular Testing

You will have to test your home for radon once every two year after installing your home’s radon mitigation system. These at-home test kits cost around $20, making them an inexpensive way to ensure you are safe and protected. Many states also offer free or discounted tests for homeowners.

Now that you are fully aware of how much a radon mitigation system generally costs, you can prepare for installation. While the price tag can seem daunting, these safety devices are critical for reducing the levels of this deadly gas within your home. Don't hesitate to implement your radon reduction system as soon as possible!
