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

Radon mitigation system costs in Orlando range from $786 to $1,276, with an average cost of $1,031. Ultimately, your project total will depend on the mitigation approach you choose—whether that’s active soil depressurization, passive depressurization, or another method. Here’s how to calculate your costs.

Radon Mitigation Cost Factors 

The cost of radon mitigation in Orlando, FL, depends mainly on the following factors.

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 

The size of your house can play a role in your radon mitigation costs, too. If you have a spacious property, prepare to spend an extra $500 to $1,500 on radon mitigation. 

Since larger properties cover more ground, they also have more areas where radon could seep in. As a result, your radon reduction pro might have to use more materials on your system (and spend additional time setting it up). 

Cost by Home Age

In addition to your home’s size, its age can also influence the price of this project. That’s because older houses often have more cracks and gaps where radon can enter—and if so, your contractor will have to spend additional time addressing these problem areas. This can drive up your labor costs and your final bill.

Radon Mitigation Pro Costs

In addition to the factors above, there are a couple more costs you’ll incur when removing radon from your house.

Permits

Since radon mitigation systems run on electricity, you’ll need an electrical permit before installing your system. Your pro should manage this part of the project, but it doesn’t hurt to confirm this before any work begins. For an average-priced radon mitigation system in Orlando, an electrical permit would cost less than $100.

Labor

Professional labor is another expense to consider when budgeting for a radon reduction system. When you request a quote from a radon detection and reduction specialist in Orlando, FL, you should see the cost of labor included. 

In Florida, radon mitigation pros must have a valid certification from the Florida Department of Health, so be sure to verify your contractor’s credentials before offering them the job.

Additional Pros to Consider Hiring

In some cases, radon mitigation requires more than one professional. You might also need:

• Electrical work: You may have to bring in a licensed electrician for certain electrical work, like installing a radon fan or running new wiring. The average cost to hire an electrician in Orlando ranges from $161 to $503.

• Foundation repair: Fixing a cracked or damaged foundation is another job best left to a qualified professional. In Orlando, foundation repair costs between $1,943 and $10,263.

• Encapsulation: To prevent radon from entering your home through your crawl space, a pro may need to install barriers and insulation along the floor and walls of your crawl space. Also known as encapsulation, this project starts around $5,000.

Does a Radon Mitigation System Increase Home Value?

According to the Florida Department of Health, one in five homes in the Sunshine State has radon levels above the “action level” established by the Environmental Protection Agency (EPA). 

However, since radon is colorless and odorless, homeowners often don’t realize that this harmful gas is entering their property. That’s where a radon mitigation system comes into play. Not only can it protect your health and safety, but it can also boost your home’s value and make it more appealing to future owners.
