Cost Insights
Active suction soil depressurization is the most common method in Phoenix homes and costs $1,200 to $2,500.
If your home is older or on the large side, you’ll likely pay more for installation.
A majority of Phoenix homes built after 2010 already have passive systems installed.
About 12% of Arizona homes have elevated radon levels, so a mitigation system installed by a pro can preserve your home value.
Installing a radon mitigation system in Phoenix, AZ, costs $1,031 on average, with most homeowners here spending between $786 and $1,276. The biggest cost factor is the type of radon mitigation method you choose, with active systems costing more than passive. Your home’s age and size can also play a role in the total project cost.
Radon Mitigation Cost Factors
Radon mitigation system costs in Phoenix, AZ, depend on what mitigation method works best for your home’s layout, but house size and age can also influence the project total.
Cost by Method
The cost of a radon mitigation system 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 in Phoenix, AZ | Description |
|---|---|---|
| Sealing the basement | $400–$5,000 | Half as effective; may require repeated resealing |
| Active suction soil depressurization | $1,200–$2,500 | Most common method; PVC pipe suctions gas from beneath foundation |
| Passive depressurization | $500–$2,500 | Vents radon through PVC piping using pressure differences; low efficiency at high levels |
| Wall-based systems | $500–$3,000 | Cinder block wall creates vented cavity to exhaust radon |
| Ventilation systems | $1,300–$2,500 | Two fans remove radon and vent it outside |
| Water mitigation | $2,500–$4,000 | Uses carbon and aeration to remove radon from water |
Cost by Home Size
Installing a radon mitigation system in Phoenix costs $0.26 to $1.32 per square foot of house. So, for the average 1,900-square-foot house in Phoenix, you’d spend between $500 and $2,500 to install a radon mitigation system. Here’s what you can expect to spend for radon mitigation based on the square footage of your home:
| Home Size (Sq. Ft.) | Average Cost |
|---|---|
| 1,000 | $260–$1,320 |
| 1,500 | $390–$1,980 |
| 1,900 | $500–$2,500 |
| 2,500 | $650–$3,300 |
| 3,000 | $780–$3,960 |
Cost by Home Age
The method of mitigation has the biggest influence on cost, but the older your home, the more you’ll spend on installing a radon mitigation system, especially if you need to seal cracks in the basement. By comparison, new-construction homes and even homes built since 2010 often have passive systems already installed, which can save you money if you upgrade to an active system.
| Home Age | Average Cost |
|---|---|
| New construction | $500–$1,500 |
| Younger than 30 years | $800–$2,500 |
| Older than 30 years | $1,200–$5,000 |
Radon Mitigation Pro Costs
Because radon is a radioactive gas and is the second-leading cause of lung cancer in the U.S., it’s critical to let a radon testing pro in Phoenix, AZ, handle the entire project, from testing to system installation. DIYing increases the risk of exposure to radon during the project and could lead to expensive mistakes that only increase your family’s long-term exposure to this dangerous gas.
Labor
In Phoenix, labor rates for radon testing and mitigation system installation come out to $50 to $150 per hour, per worker. However, you’re not likely to see hourly billing in your contract. Instead, most radon mitigation services bill a project total, and they include labor and permit costs in that quote.
Permits
Radon mitigation projects will require your contractor to pull the appropriate permits from the city’s Planning & Development Department. Permit costs vary based on project specifics, with most permits costing between $25 and $200. Projects that involve foundation repairs, basement sealing, or electrical work will have higher permit costs.
Warranty
Radon mitigation systems often include a five-year warranty, which primarily covers any fan malfunctions. A radon mitigation fan has a lifespan of 10 to 15 years but may require a replacement sooner. You can extend your warranty another five years for $200 to $500, which could help you save on the cost of a radon fan replacement down the road.
Additional Pros to Consider Hiring
While you’re installing a radon mitigation system, you may also want to consider other upgrades—like finishing your basement, repairing a foundation, or upgrading your electrical system—to further decrease radon risks.
Electrician cost: $170–$570
Basement finishing cost: $2,800–$100,000
Foundation repair cost: $2,130–$7,010
Does a Radon Mitigation System Increase Home Value?
In Arizona, 12% of homes have elevated levels of radon due to local soil conditions. So, investing in a radon mitigation system could ultimately help you avoid inspection delays and preserve home value if you’re looking to sell your property. A radon mitigation system may not increase home value the way an updated kitchen or new roof could, but it helps maintain your existing value.
