1. All exterior windows on all levels of the building must be kept closed. All exterior doors must be kept closed except for momentary entry and exit.
2. These "closed building conditions" must have been maintained for 12-hours prior to the start of the test as well as throughout the duration of the test.
3. The thermostat must be set to normal occupied operating conditions with the temperature set between65 and 80 degrees.
4. The radon testing device must not be moved, covered, or tampered with.

1. The Continuous Radon Monitor is the most sensitve test available. Our technician will place the CRM within your home and it will register the radon levels hourly over a 48 to 72-hour period.
2. The levels are then evaluated to determine the threat level in your home.
3. Our technician will collect the CRM at the end of the testing period.
4. Our company will email a report based on the measurements recorded and will make recommendations accordingly.
1. If your radon levels exceep 4.0 pCi/L (picocuries per liter), EPA recommends your home be mitigated.
2. Because there is no known safe amount of exposure to radon, EPA also recommends that Americans consider fixing their home with radon levels between 2.0 pCi/L and 4.0 pCi/L.
3. If your level is below 2, no immediate action is recommended.
4. If you personally want to try to get your level lower, a few ways to supplement your mitigation system is to increase air flow in your house by opening windows and using fans and vents to circulate air and seal cracks in floors and walls.
5. EPA also suggests radon testing at least every two years and more often if you have done any renovations or additions. Also, if you intend to finish a basement that hasn't been tested for radon, you will want to make sure you test first.
