When you schedule a test from Branch Property Investigations, one of our radon testing technicians will come to your home and identify the lowest living area in your house. For most homes in Minnesota, this is the basement.

Our technician will set up the radon monitor at the lowest living area of your home, and configure it for 48 hours of continual monitoring. (If additional levels of a foundation system are discovered, extra radon unit(s) are required by the MN Department of Health and will need to be added for an additional fee.) 

12 hours prior to the start of your test and during the two days your home is being tested, you will need to avoid opening any windows and ideally should not run your air conditioning system. Normal opening and closing of your entrance door is okay, but you should not leave it propped open for any reason. The radon monitor should not be moved for any reason. After two days, the technician will return and collect the tester, and we begin the process of analyzing the results. Typically the test results and report are made available to the client later that same day.
