Radon Mitigation System Upgrades: When and Why They’re Needed

January 22, 2026      

A radon mitigation system is one of the most effective ways to protect your home and family from harmful radon gas. However, like any home system, it may not maintain peak performance forever. At Radon Guys, we help homeowners understand when and why radon mitigation system upgrades are necessary to ensure your indoor air remains safe.

Radon mitigation systems work by venting gas outside before it can accumulate indoors, but over time, several factors can reduce their effectiveness. Components such as fans, piping, and electrical connections can wear out. Changes to your home, like finishing a basement, altering a crawlspace, or adding insulation, can affect airflow and radon levels. Even environmental changes, including soil shifts, nearby construction, or extreme weather, can influence how radon enters your home.

You may need an upgrade if radon test results rise above the recommended safe level of 4 pCi/L, if you notice unusual noises from the fan, or if the system’s components show signs of wear or damage. Some older systems may also be less energy-efficient, leading to higher utility costs while providing reduced protection.

Radon system upgrades often involve replacing or enhancing the fan to improve airflow, repairing or replacing piping, or adjusting the system to account for changes in the home or environment. A professional inspection is the best way to determine what your home needs to keep radon levels safely under control.

Investing in a radon mitigation system upgrade isn’t just about maintaining equipment — it’s about protecting the health of your family and ensuring peace of mind. At Radon Guys, we provide expert inspections and tailored upgrades so your system continues to work efficiently year after year, keeping your home safe from invisible threats.
