Shimming A Door Hinge To Keep The Door Open

Slip a 1 16 in thick cardboard shim strip behind each hinge photos with steps 1 and 2 below.

Shimming a door hinge to keep the door open.

If the problem persists repeat the process to add a second shim to the hinge. Common problems associated with door openings require shims to be installed in the correct place to solve the issue. Remove the screws from the hinge you need to shim using a screwdriver or a drill and screwdriver bit. You can buy them at home centers or online for less than 15.

When shimming the door the goal is to make sure that once the frame is nailed the gap between the door and the frame is equal all around the door. Slide the shim behind the hinge that needs the extra spacing then drive the screws back in tightly and check the operation of the door. Open and close your door then let it hang freely to test whether the door is now level enough to work properly. Sometimes the gap is far too wide.

This job can be a hassle especially if you have painted trim. Self centering bits come in sizes to fit cabinet and full size door hinges. So try this trick first. As you can see in the initial picture and video the latch was lower than the striker plate.

To readjust the door frame you have to remove the trim along the latch side to get at the shims. Most pre hung doors come with a 1 8 inch gap between the door and the frame on the hinge side and the top. I ve seen shims used behind the hinge leaf to adjust the gap but bending the hinge takes less time. This video will cover the basics of shim.

Reinsert the pin tapping it gently into place from the top with your hammer. Adjust the gap by bending the hinges. Shimming correctly can raise or lower the latch bolt to align with the striker plate. Open the hinge side gap by spreading the hinges.

Remove the shim and test the door.
