To shim a door hinge, follow these steps:
1. Remove the hinge pin and take off the door.
2. Identify the gap between the door and the frame by closing the door and checking for any misalignment.
3. Cut a thin piece of cardboard or plastic into the shape of the hinge and place it in the gap.
4. Reattach the hinge and insert the hinge pin back in place.
5. Test the door to ensure it closes smoothly and without any gaps.
Shimming a door hinge helps to correct misalignment and ensures a proper fit between the door and the frame.
If your door is not closing properly, it might be due to loose hinges. One of the most common issues is that the screws have come out, causing the door to sag. You can fix this by tightening the screws. Alternatively, if the jamb is not level, it can cause the door to lean. Although you can reset the jamb, an easier solution is to use shims to adjust the door. This method is suitable if the gap difference between the opposite jamb and the top and bottom of the door is less than 3/8 inches. If the gap is more significant, you may need to reset the jamb.

Choosing the Right Shim
You can accurately measure the thickness of the shim you need by measuring the gaps between the top and bottom of the door and subtracting the measurements. Using a ruler instead of a tape measure will give you a more precise measurement. Thin cardboard is a suitable material for shims since it won’t split or compress when you drive screws through it or tighten the hinge screws. You can layer several pieces of cardboard to increase the thickness of the shim.
Using Premade Shims
You can buy premade shims that fit the hinges on your door if you prefer. These shims are pre-drilled, making them easy to use. You can stack two shims to increase the thickness. They are the best option for heavy entry doors and steel doors.
Installing the Shim
You can install the shim between the hinge and the jamb or between the hinge and the door. However, you need to do this while the door is open. Wedge a piece of wood under the door to support it and prevent it from moving while you unscrew the hinge.
Remove the screws from the hinge that needs shimming using a screwdriver or a drill and screwdriver bit. If the door has three hinges, remove the screws from the middle hinge as well. Slide the shim behind the hinge that needs extra spacing, then drive the screws back in tightly and check the door’s operation. Add or remove cardboard as needed to straighten the door.
Leave the middle hinge unattached while making these adjustments. Once the door is straight, you can reset it by driving the screws back in. The door should stay level, but if it doesn’t, you may need to shim the middle hinge as well. Use a shim with half the thickness of the material you used for the other hinge.
FAQ
1. What is the purpose of shim a door hinge?
Shimming a door hinge is done to ensure that the door is properly aligned and functions smoothly. Over time, the weight of the door may cause it to sag or become misaligned, resulting in difficulty while opening or closing. By using shims, which are thin wedges or spacers, between the door hinge and the door jamb, you can adjust the angle and position of the hinge. This helps to level the door, eliminate any gaps, and improve its overall functionality.
2. What materials do I need to shim a door hinge?
To shim a door hinge, you will need a few basic materials. These include shims, which can be made of wood, plastic, or metal, depending on your preference. You may also need a hammer or mallet to tap the shims into place, a utility knife to trim the shims if necessary, and a screwdriver to remove and reattach the hinge screws. It is important to choose shims of the appropriate thickness to ensure a proper fit and alignment.
3. How do I shim a door hinge?
Shimming a door hinge involves these steps:
1. Begin by removing the hinge screws from the door jamb using a screwdriver.
2. Place the shims between the door hinge and the door jamb. Start with one shim at a time, inserting it in the gap between the hinge and the jamb.
3. Tap the shim gently with a hammer or mallet to secure it in place. Check the alignment and adjust if necessary.
4. If the hinge is still not aligned properly, add more shims until the desired alignment is achieved.
5. Trim any excess shim material using a utility knife.
6. Reattach the hinge screws and tighten them securely.
By following these steps, you can effectively shim a door hinge and improve the overall function and appearance of your door.
