1. 1)Confirm that the photoelectric safety beam is a maximum of 6-inches above the floor.

  2. 2)Test the safety beam (non-contact reversal mechanism), and verify that the door returns to fully open position.

  3. 3) Test the contact reversal safety system, and verify that the door returns to fully open position. The mechanism should be set to reverse itself at 10 to 15 lbs. of resistance.

   The two most common defects we find in the Gainesville area are: a safety beam set too high, and the contact reversal system set to too high a resistance before it reverses.

   Manually operated and older, tilt-up garage door are evaluated somewhat differently, but with door operation safety as the primary concern. Our inspection sequence is based on Technical Data Sheet #167, issued by DASMA (Door & Access Manufacturers Association International), which is considered an industry standard. You can visit their website for more information at : http://www.dasma.com/.


While we hope you find this series of articles about home inspection helpful, they should not be considered an alternative to an actual home inspection by a local inspector. Also, construction standards vary in different parts of the country and it is possible that important issues related to your area may not be covered here.
