Cost of Radon Mitigation System by Method
The cost of a radon mitigation system often ranges from $805 to $1,326, and it depends on the chosen approach, which might be sealing the basement, depressurization, or lower-level pressurization. The depressurization method happens in one of two types: active suction (soil depressurization) or passive depressurization.
Here’s what to expect for pricing by radon mitigation method:
| Method | Cost Range | Description |
|---|---|---|
| Sealing the Basement | $400–$4,600 | Only half as effective as other methods; you may need repeated resealing |
| Active Suction Soil Depressurization | $1,000–$3,000 | The most popular method; uses PVC pipe to suction gas trapped beneath your basement floor or crawl space, preventing radon from entering through foundation cracks |
| Passive Depressurization | $500–$2,500 | PVC pipes run beneath the foundation or crawl space and up the exterior walls; uses the difference in air pressure between the radon and the ambient air to push out the radon; not efficient for high radon levels |
| Wall-Based Systems | $500–$3,000 | A wall of cinder blocks is placed around the radon-affected room, and an exhaust pipe vents the gas from the space between the blocks |
| Ventilation Systems | $1,300–$2,500 | Two fans remove radon and vent it outside |
| Water Mitigation | $1,200–$5,000 | Carbon absorbs radon and efficiently cleans your water using bubbling or spraying aeration that disperses water molecules, releasing radon that is removed by a fan |
Cost by Location
On average, radon mitigation systems are more expensive in areas with higher living costs like Los Angeles ($2,000) as opposed to lower-cost places like Kansas City ($700). Prices are also affected by the prevalence of radon in your area, the number of nearby specialists, region-specific EPA regulations, and climate.
Here’s what you might pay for radon mitigation systems in various cities:
Kansas City: $700
Denver: $800
Boston: $1,000
Atlanta: $1,100
Chicago: $1,200
New York: $1,400
Albuquerque: $1,500
Los Angeles: $2,000
Radon Mitigation System Cost Factors
The cost of a radon mitigation system is also influenced by additional factors, including home size, foundation type, radon testing, and more. Here’s what to expect.
Radon testing: $150–$700
Home size: $500–$1,500 more for larger homes
Permits: $25–$150
Electrician: $50–$100 per hour, if required for wiring, installing a radon fan, or other electrical work
Unfinished basements: $4,600 if you need sealing and a ventilation system
Additional encapsulation: $1,500–$15,000 if needed (for example, in a crawl space without a foundation slab)
Energy costs: $100–$300 per year
Extended warranties: $200–$500
Installing a Radon Mitigation System Yourself vs. Hiring a Pro
While installing a radon mitigation system might cost $805 to $1,326, you should never attempt this project as a DIY. Radon is an odorless, invisible gas that can cause cancer at high levels of exposure. Sometimes, enough radon is present in the ground to seep into homes through the basement. Proper mitigation ensures long-term health.
Here’s why you should always hire a local radon mitigation specialist to install a system for you:
Proper installation requires specialized skills, tools, and knowledge. Pros design a specific system for your home’s needs.
An incorrectly installed system can compromise the air quality in your home and create a dangerous environment.
Many real estate transactions expect radon mitigation to be done by certified professionals.
Radon mitigation systems must meet local building codes and EPA guidelines—and pros understand how this works.
Hiring a pro provides post-installation testing and a warranty.
Tips to Save Money When Installing a Radon Mitigation System
The costs of home radon mitigation can add up quickly. Here are a few tips to help you save without cutting corners on this important project.
Use a home testing kit ($15 to $60 on average) to see if you have enough radon to warrant professional testing and mitigation
DIY sealing of cracks and gaps in an unfinished basement prior to mitigation might save at least $100 to $500 on professional labor and materials. Note that sealing alone won’t eliminate radon.
Get three or more quotes from radon testing companies near you to ensure you get a competitive price, which often falls around $1,043.
See if companies offer referral programs or discounted rates (like 5% to 10% off the total installation cost) for new customers.
Talk to your tax professional about the possible tax benefits of paying for the system using a health savings account or flexible spending account (HSA/FSA).
Find out if you qualify for tax advantages or home repair grants in your local area. These incentives might cover $500 to $1,500 of your system.
Next Steps
You should always hire a pro to install a radon mitigation system, as incorrectly installed systems can compromise air quality and create a dangerous environment.
There are different types of radon mitigation systems, but they all function in a similar way—sucking the radon out of your house and dispersing it outside.
A radon mitigation system might cost anywhere from $400 to $1,800, and a pro can give you a personalized quote.
