If your home has been tested positive for radon, what happens next? What is the process when it comes to mitigating a home for radon? This is what we’re going to talk about today in Part 3 of our 4 Part series on radon with St. Louis Radon Test and Mitigation Services.

What is the installation process?

Radon is a gas that comes from underneath the home. Radon mitigation systems create a vacuum that removes the gas before it comes into the living area.

The process will begin with core drilling into the concrete floor of an unfinished part of the basement and excavating material from underneath the home. Then PVC piping will be put into the basement floor, sealed off to make it airtight, and routed to an inline fan that will exhaust the radon above the roofline.

All systems primarily operate the same way by pulling air from underneath the home. There are two primary methods depending on the home’s design.

  1. From the basement to above the roof-line directly. The fan is placed outside the foundation wall.
  2. From the basement into the garage and into the attic space. The radon fan is placed in this attic space above the garage and the radon is discharged above the roof-line.

Does the system make noise?

Anything with moving parts or a fan is going to make some noise, but a radon mitigation system shouldn’t be disruptive. There will be a hum, but it will not be as loud as a refrigerator or an AC system.

Also, the location of the fan will be considered before installation. For instance, the fan will not be placed outside of a bedroom. If the fan is installed in the attic space over the garage, you should not be able to hear the noise from within other areas of the home.

Are there any guarantees?

St. Louis Radon Test and Mitigation Services offers a 5 year parts and labor warranty. They can guarantee that they will get the radon levels below the required 4.0 pCi/L, but they do their best to get levels as low as possible, often getting the levels below 1.0 pCi/L.

Homeowners must get their house tested for radon again after the system is installed to see how effectively it’s working. Depending on the layout, some houses must have more than one radon system in them.

What is the cost?

The cost of installing a radon mitigation system will depend on the size and design of the home. Most radon system will run up to $1000, and usually fall within $750-$800. Certain homes may need a radon system for separate places in the home because of their structure and foundations. Larger homes may need larger venting equipment and fan sizes, which will add to the price.
