Understanding the cost of Radon Mitigation Systems

Radon gas is a serious health concern, and knowing the importance of testing your home for radon is the first step. The next is understanding the cost of mitigation. At Utah Radon Services, we prioritize quality systems and transparent pricing.

Average cost

Most radon mitigation systems in Utah typically range from $1,800 to $2,300. This cost can vary based on several factors:

  • Home Size and Layout: The lowest level's square footage and overall home design influence the system's complexity.
  • Fan Type: Different fan types may be required based on your home's unique needs.
Factors that may increase the cost:
  • Multiple Suction Pits/Systems: Larger homes or complex layouts may require more than one suction point or even multiple systems for effective mitigation.
  • Open Dirt Areas: Crawl spaces or other exposed dirt areas may need a vapor barrier installation, adding to the cost.
  • Location: Homes located more than 50 miles from Draper, Utah, may incur a trip fee.

Getting an estimate

For most homes, we offer a free over-the-phone bid for a radon mitigation system; you can easily get started by calling us directly at 801-871-0715 or by filling out our convenient online form.

In-Person Estimates

Some homes have structural complexities that make a phone estimate difficult. We can arrange an in-person bid for a fee, depending on availability. These appointments typically last around 30 minutes, and we're happy to answer any questions you have.

Types of radon systems

Interior radon systems

This is our most popular type of system, and more than 50% of the homes we fix choose this option.

An interior system first requires us to drill through the lowest concrete floor slab in the home in a discrete location such as a mechanical room, storage room, or the back of a closet. Second, we install a PVC pipe from the lowest level of the home up through the roof. The goal of all of our installations is to hide the system as much as possible. The radon system fan is then installed in the attic to exhaust the gas up through the roof with a single pipe and special roof vent.

In most Utah homes, these installations average a total cost between $1,900–$2,300.

Exterior radon systems

Sometimes, there just isn’t a well-hidden route possible inside the home. In this case, an exterior radon system is the best fit.

These systems start the same as an interior system by drilling through the lowest slab, but they then transition to the outside of the home right above ground level. Whenever possible, this will be on the side or back of the home out of view and away from any high-use areas such as patios and entryways. 

The radon fan for an exterior system is the size of a basketball and is installed onto the outside pipe just a foot or two above the ground (where it can easily be hidden by a bush!). Above the fan, we transition the pipe to an aluminum downspout to match the home’s current rain gutters. At no extra cost, we can often paint this downspout to blend it in with the existing color of the home.

An exterior radon system also costs around $1,800–$2,300 on average.

Crawl space radon mitigation systems

We are very familiar with crawl spaces and their unique installation requirements. Crawl spaces add another layer of complexity to any radon system installation, and most crawl spaces need to be viewed in person to determine the exact price.

A general rule of thumb for crawl space radon systems is that the total cost will be the price of a normal radon system, plus approximately $2–$3 more per square foot of the crawl space.

The cost of a crawl space radon mitigation system depends on:
  • The footprint size of the crawl space 
  • The crawl space height from the floor to the trusses/HVAC piping above
    • We need a minimum of 24” for our workers to be able to crawl around and work in the crawl space. The more headroom, the easier, quicker, and less expensive it will be for labor costs.
  • The condition of the crawl space
    • Is the space covered in clean dirt or gravel on the ground, or is it filled with construction debris and rocks that must be removed by us first?
  • Dead animals found in the crawl space tend to increase the price of the installation

Other factors that may increase the cost of a radon system

Large homes

Homes with a larger footprint may necessitate additional radon suction pits or multiple mitigation systems. An in-person inspection is almost always required for accurate bidding on large homes.

Sub-slab ducting

If your home's cement slab has unsealed sub-slab ducting, mitigation can be challenging. Please inform us during your bid request. In severe cases, you may need a separate company to seal these vents, potentially costing several thousand dollars.

Radiant floor heating

Lines running through the cement slab often add cost, as we need to use FLIR cameras to locate pipes and avoid them during drilling.

Exotic materials

If your home has unique exterior elements, such as copper gutter downspouts, we can match these, but a copper downspout adds approximately $600 to the cost.
