Commercial doors are often subjected to more wear and tear than residential doors, so it is important to troubleshoot any problems that may arise. One common problem is a door that does not close properly. This can be caused by a number of factors, such as loose hinges, warped doors, or uneven door frames.
If you are experiencing this problem, the first step is to identify the cause. You can do this by checking the hinges to see if they are loose, and by measuring the gap between the door and the door frame. If the gap is uneven, it may be necessary to shim the hinges.
Shimming hinges is a relatively simple process that can be done with a few basic tools. First, you will need to identify the problem hinge. Once you have identified the hinge, you will need to remove it from the door. Then, you will need to measure the gap between the hinge and the door frame. Once you have measured the gap, you can cut a shim to the desired size. Finally, you can insert the shim into the gap and re-attach the hinge to the door.
