How to Fix a Door Hinge That Is Broken

A broken door hinge is a more serious problem than a loose one — but it's still a straightforward DIY repair in most cases. Here's how to assess the damage and fix it properly.

Types of Broken Hinges

• Bent hinge leaf: The flat metal plate has warped or bent out of shape
• Cracked or snapped hinge leaf: The metal has fractured, usually from impact
• Broken knuckle: The barrel section that holds the pin has cracked
• Sheared screws: Screws have snapped off inside the wood
• Torn-out hinge: The hinge has pulled completely out of the door or frame

Step 1: Assess the Damage

Open the door and inspect each hinge carefully. Determine whether the hinge body is damaged or just the screws/pin. This tells you whether you need a full replacement or a simpler fix.

Step 2: Support the Door

Before removing a broken hinge, support the door with a wedge or have a helper hold it. A door with a broken hinge can fall suddenly and cause injury.

Step 3: Remove the Broken Hinge

Remove the hinge pin first (tap from bottom with screwdriver and hammer), then unscrew the hinge leaves from both the door and the frame. If screws are stripped, use a screw extractor.

Step 4: Replace the Hinge

Match the replacement hinge to the original: same size (typically 3.5" for interior doors), same corner radius, and same finish. Install the new hinge in the existing mortise.

Step 5: Fix a Torn-Out Hinge

If the hinge pulled out of the wood entirely, the screw holes need rebuilding before reinstalling:

1. Fill the holes with toothpicks and wood glue
2. Let cure overnight
3. Reinstall the hinge with 3" screws that reach the wall stud

Step 6: Straighten a Bent Hinge Leaf

If the hinge leaf is only slightly bent (not cracked), you may be able to straighten it. Remove the hinge, place it on a flat metal surface, and tap it flat with a hammer. Reinstall and test.

Step 7: Replace Just the Hinge Pin

If only the pin is damaged (bent or broken), you don't need to replace the whole hinge.

When to Call a Professional

If the door frame itself is cracked or the mortise is severely damaged, a professional carpenter may be needed to repair or replace the frame section before a new hinge can be installed properly.
