Radon mitigation system questions

Your radon system questions answered

How does my radon mitigation system work?

Radon mitigation systems are designed to significantly reduce radon gas and your risk for radon-induced lung cancer. This is done through two similar processes: Sub-Slab Depressurization (for homes with slab foundations) and Sub-Membrane Depressurization (for homes with crawlspaces).

Sub-slab depressurization (most common)

A suction pit or pits are created by drilling a hole through the basement floor or slab and removing approximately three five-gallon buckets of dirt. A pipe is inserted into the hole, extending through the home to an outdoor exhaust point where the gas is quickly diluted. A fan is installed on the pipe to create negative pressure beneath the slab, preventing radon from entering the home.

Sub-membrane depressurization (homes with crawlspaces)

This method is typically used in buildings with crawlspaces. A vapor barrier or membrane is installed on the crawlspace floor to prevent radon gas from seeping into the home. A pipe and fan are then installed to create negative pressure beneath the membrane, similar to the sub-slab depressurization method. The radon gas is drawn out and vented safely outside.

What maintenance is required for my radon mitigation system?

Your radon mitigation system requires very little maintenance. There are just two basic things to do:

Occasionally check the system’s airflow gauge (a manometer) to ensure the fan is running.
Listen for irregular noises (clanking or loud whirring). Your radon fan has a 5-year manufacturer warranty. While most fans will last longer, contact us if you hear irregular noises.

Can I perform the maintenance to my radon mitigation system?

You can perform some maintenance tasks, while others require our professional assistance. Checking the manometer, reattaching it if it were to fall off, listening for irregular noises, and keeping the system clear of debris are all tasks you can do. Replacing the fan, re-routing the pipes, and changing any of the components need to be done by us to maintain the warranty.

What is a manometer?

A manometer is a tool that measures how much air is flowing through your radon mitigation system. It’s the best and easiest way to tell if the system is running properly.

What should I do when the manometer shows the system isn't working?

If the fluid levels in the manometer are even, the fan has stopped working.

Make sure the manometer tubing is connected to the pipe.
Untangle any kinks in the manometer tubing.
Ensure power is being supplied to the radon fan (a breaker could have been flipped causing power to stop flowing to the fan). If this is the case, simply turn the breaker back on.

If the above does not fix the issue, please contact us at 801-871-0715.

Do I need to test my home's radon levels after the system has been installed?

Yes. It is recommended to test your home one week after the installation and then every two years after that.

Can I turn the radon fan off during certain times of year?

No. It is critical that you run the fan 24/7 to ensure radon gas isn’t entering your home.

What is the warranty on my radon mitigation system?

Your radon system includes two separate warranties:

Fan warranty: Your fan has a 5-year manufacturer warranty. It will typically last much longer (usually 10 years or more). If the fan fails within the 5-year warranty period, we will replace it at no cost. After the 5-year warranty expires, we will replace the fan at a cost.
System warranty (everything else minus the fan): Check the warranty information for your specific home on the mitigation quote we provided you with. If your system has a warranty, it is a lifetime warranty. This means we will do anything within reason to repair or replace the system at either no, or some cost, depending on the specifics of your individual warranty.

How much does it cost to run my radon mitigation system?

The only ongoing expense of a radon mitigation system is the electricity used to power the fan. The cost depends on many factors like fan size, soil type, and the number of fans installed. For a typical one-fan system, the cost should be between $50 to $100 per year (about the same cost to run a 75-watt light bulb 24/7).
