When It's Time to Service your Radon System

"But we had the radon fixed 15 years ago"...

Radon is a naturally occurring gas that originates in the soil beneath our buildings. Our buildings change over time and radon changes too. Radon levels in a home can fluctuate naturally, can be influenced by HVAC systems, waterproofing work, construction and renovations, energy efficiency updates, disrepair of an existing radon system, and many other reasons.

If you have a radon system, you should test for radon at least annually. Ideally, you would perform two measurements per year: one in the heating season and one outside of the heating season. This will make you aware of any seasonal radon changes that may be occurring.

If you don’t have a radon system, you should retest at least every five years (at a minimum) or after any changes to the home.

Here are just a few good reasons to get your radon system looked at by a professional:

  • • Radon levels tested too high
  • • Airflow gauge on pipe is missing, fluid in gauge is evaporated, or fluid in gauge is even on both sides
  • • Radon system is making noise (rattling, loud humming, screeching, etc.)
  • • Radon fan has stopped working
  • • Radon piping or fan is missing or damaged
  • • Radon piping on outside of house does not extend above the roof
  • • You can hear water trapped inside of the radon piping (more than just a gurgling sound during a high water table)
  • • Sump pit(s) or french drains are uncovered
  • • French drains, sump pits, or other waterproofing work was performed since the last radon service
  • • The basement was finished since the last radon service
  • • Anyone other than a certified radon business has altered or removed any part of your radon system
  • • An addition was added to the house
  • • Energy Improvements like new windows, new roofing, siding
  • • Gaps or degradation in original sealant work
  • • New cracks in floor since the last radon service
