Because household activity can significantly affect radon levels, please make sure to...


  • Avoid using your fireplace, wood-burning stove, dryer and other appliances that move air in and out of your home
  • Keep all exterior doors and windows closed 12 hours prior to and during your radon test
  • By using a radon machine we can delay the test if the home is not ready (windows open). It will tell if the conditions of the home changes during the test.
  • Keep kids and pets away from the radon testing equipment
