How Much Does a Radon Mitigation System Cost in Austin? [2026 Data]

The average cost to install a radon mitigation system in a home in Austin, TX, is $1,031. Your actual costs will depend on the type of system, and prices can range between $786 and $1,276. A home’s age and square footage can also affect the total cost, along with several other factors we’ll discuss here.

Radon Mitigation Cost Factors 

From the installation method used to the age and size of a home, these are the primary factors that affect the cost of a radon mitigation system installation in Austin, TX.

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:

Cost by Home Size 

Home size will affect the prices Austin homeowners will pay to install a radon mitigation system. As with any other home improvement project, higher square footage requires more materials and equipment as well as more hours of professional labor, which will all drive costs higher. 

Given that the median size of Austin homes is around 1,860 square feet, homeowners here can expect to pay on the higher end of the price range.

Cost by Home Age

Older homes that have settled likely have cracks in the foundation where radon can seep in. Additionally, older homes may have fewer access points than newer homes, which means the pros will need more time to complete the work. 

However, there’s good news for Austin homeowners: The city has experienced such rapid home development since 2010 that the median age for homes is just 20 years, which could lower radon mitigation system prices.

Radon Mitigation Pro Costs

When determining your budget for installing a radon mitigation system, be sure to add in these costs.

Permits

Installing a radon mitigation system in Austin requires a permit or multiple permits, depending on the building, electrical, or mechanical work involved. The local contractor you hire will handle the process, but you can learn more about building permits by visiting the Austin Build + Connect (AB+C) website.

Labor

Not surprisingly, labor costs will be the priciest part of any project quote you request from a radon mitigation specialist in Austin. While the Lone Star State does not mandate licensing for radiation mitigation professionals, it’s smart to seek out professionals who are certified through the National Radon Safety Board (NRSB) or the National Radon Proficiency Program (NRPP).

Taxes

Austin has a sales tax of 8.25% on all purchases, which is a combination of state, city, and county taxes. Be sure to leave room in the budget to cover this tax.

Additional Pros to Consider Hiring

Some radon mitigation system installations are more complex than others, and you may have to hire additional contractors to do the necessary work, such as: 

• Electrical work: If you need updates to your home’s electrical system, you can expect to pay between $162 and $540 for an electrician in Austin, TX.

• Foundation repair: Foundation repair pros in Austin charge between $3,989 and $10,475 per project.

• Encapsulation: If your home has a crawl space, a pro might suggest encapsulation, which is the installation of vapor barriers on the floor and along the walls. If this is the case for your Austin home, expect to pay encapsulation costs of between $2 and $10 per square foot.

• Basement finishing: It costs between $7 and $23 per square foot to finish a basement. It can get costly if you have a large basement, but it will add value to your home by making the space livable, or at least more usable. 

Does a Radon Mitigation System Increase Home Value?

Although many Texas radon levels often fall within the normal limits, Austin homes may experience higher levels of radon due to the uranium-rich soil. As the uranium decays naturally, it turns into that radioactive gas, which can seep through the cracks in home foundations and compromise the health of your household. Therefore, installing a radon mitigation system not only provides peace of mind for you as a homeowner, but it can increase your home’s value should you choose to sell.
