Are radon mitigation systems effective?

Updated: Jul 20, 2022

Short answer, Yes! Properly designed and installed radon mitigation systems are highly effective at reducing the levels of indoor radon below the EPA's recommended action level of 4.0 pCi/L. However, this is not a one size fits all situation. What type of radon mitigation system works for your property depends on your radon source issue and a whole host of other factors.

The largest issue in Florida stems from building materials emanation. The incorporation of large quantities of concrete containing mined limestone (containing radon source minerals) in our building structures, has led to radon gas emanation into the indoor environment. This in combination with our tighter energy efficient building construction has led to elevated indoor levels exceeding the EPA guideline level in many of our Florida structures. When radon is present, that means its decay particles are present. The radon decay particles, or RDP's, are what is actually harmful to the human body and, when left unmitigated, can cause lung cancer when they are inhaled.

Historically, we have found that, in Florida, 90 percent or more of high-rise residential construction built after 2004 will have elevated levels of radon in the indoor environment because of building materials emanation. This goes for 1st floor units all the way to upper floor units. Townhouses and apartments with a concrete deck above and built after 2004, will likely have elevated indoor radon levels. Multi-story single family CB residential homes built after 2004 have a high potential for elevated indoor radon levels.

EnviroHome has found incredibly effective and efficient ways to mitigate this type of source issue. Our primary approach to designing a radon mitigation system for this type of radon is to dilute. By bringing in higher quantities of fresh air and ensuring the house is properly exchanging outdoor and indoor air, we are able to bring the levels of radon below the EPA's recommended action level of 4.0 pCi/L. Designing and installing a radon mitigation system that dilutes your air in an efficient way, is something EnviroHome specializes in and has the added benefits of increasing your property’s overall indoor air quality.

But building material emanation is not the only way radon gets into our home. In fact, across the rest of the country, the biggest source of indoor radon comes from the ground underneath our homes. Deposits of radon coupled with the improper pressurization of a home can cause large issues. The solution to this issue is a combination of tried and true mitigation techniques including active soil depressurization, sealing entry pathways, and ensuring the flow of air throughout the house is properly directed.

What does this all mean for you?

Our team of NRPP certified engineers and radon mitigation specialists looks at each property individually to assess the type of mitigation needed. One size does not fit all. Depending on the size of the property, age of the building, location and environment, levels of radon present, overall building structure, your mitigation plan will be specifically designed and built to address the building’s issue using a combination of techniques that our team has mastered and in some cases pioneered.

Radon Mitigation System
EnviroHome can use ERVs to reduce radon levels in your property.

Our goal is to not only reduce the radon in your property to below the EPA's recommended action level of 4.0 pCi/L, but to improve your overall indoor air quality, to us, these two goals are one and the same.
