Understanding the cost of radon mitigation systems in Utah

What you need to know about radon mitigation system costs

More and more homeowners are learning about how radon gas causes lung cancer and the importance of testing their homes for radon. It's even more important to know that not all radon mitigation system types are the same, and not all service providers install quality systems like Utah Radon Services does.

Average cost

The cost of radon mitigation depends on several factors, including the square footage of the home's lowest level, the layout, and the type of fan needed, but generally speaking, the cost will be between $1,800 and $2,300. Factors that would increase the cost include needing more than one suction pit and/or system, open dirt areas that need to be covered with a vapor barrier, and your home's location (homes more than 50 miles from Draper require a trip fee). 


Free estimates

For most homes, we can give a free bid for a radon mitigation system over the phone. However, some homes have structural complexities that add to the difficulty of the installation. We are always happy to come to your home to do an in-person inspection for your bid at no charge. This appointment usually takes about 30 minutes, but we will happily stay to answer any questions you may have.

Types of radon systems

Interior Radon Mitigation System

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–$2,000. 

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–$2,000 on average.

Exterior Radon Mitigation System

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

If the home’s footprint is over 2,000 square feet, it may require additional radon suction pits or multiple mitigation systems. With a large home, there are many variables to take into consideration, so it is almost always necessary for us to inspect the home in person to accurately provide a bid.

Sub-slab ducting

If a home’s cement slab has sub-slab ducting that is not well sealed, it can make mitigation difficult. If you know you have sub-slab ducts in your home, let us know during the bid request so we can review this issue with you. In the worst-case scenario, you may need a company to seal the sub-slab vents, and this may cost many thousands of dollars.

Radiant floor heating

Lines running through the cement of a slab will often add cost to a radon system installation. In this situation, we need to use FLIR cameras to try to see the piping through the concrete in order to miss these pipes while drilling.

Exotic materials

Some homes will have copper gutter downspouts on the outside of their homes. We can install copper downspouts onto such homes, but it costs roughly $600 more for one copper downspout.

In the end, installing a radon system in your home is about health, safety, and peace of mind. Our goal is to make this process as easy as possible. Contact us at 801-871-0715 to get your bid today!
