A door that squeaks, sticks, or hangs crooked can make a small problem feel like a daily annoyance. Often, the hinge is to blame—and replacing it is a manageable DIY job if you choose the right replacement and support the door while you work. Here’s how to do it carefully, whether you’re changing one damaged hinge or refreshing all the hinges on a door.

When Should You Replace a Door Hinge?
A little squeaking doesn’t always mean a hinge needs replacing. Dirt or a lack of lubrication may be all that’s wrong. But replacement makes sense when a hinge is bent, cracked, badly rusted, loose beyond repair, or has a worn pin that lets the door sag or wobble.
Before buying a new hinge, look for the actual cause of the problem. A door can stick because the house has shifted, the door has swollen from moisture, or the screws have loosened. If the hinge looks straight and its screws simply need tightening, you may not need a new part at all.
Signs a hinge may be the problem
- The hinge leaves are bent or no longer sit flat against the door or frame.
- The pin is damaged, difficult to remove, or loose enough to let the door move sideways.
- There is heavy rust, cracking, or visible wear around the hinge barrel.
- Screws keep backing out, or the screw holes are stripped.
- The door sags at the handle side and hinge adjustments or tighter screws don’t fix it.
If the door only squeaks, try a suitable hinge lubricant first. Open and close the door a few times to work it into the hinge, then wipe away extra lubricant so it doesn’t collect dust. If the noise remains or the hinge is visibly damaged, replacement is the safer long-term fix.
Choose the Right Replacement Hinge
Don’t rely on appearance alone. A hinge that looks close may have different dimensions or screw-hole positions, which can leave you with extra holes or a door that won’t sit properly. If possible, take the old hinge to a hardware store or compare it directly with a replacement before removing the door.
Check the hinge size and shape
Measure the hinge when it’s open and flat, from one outer edge to the other. Also check its height, leaf width, thickness, and the distance between the screw holes. Residential door hinges commonly come in sizes such as 3½ by 3½ inches or 4 by 4 inches, but those are examples, not a guarantee. Match the old hinge as closely as you can.
Look at the corners, too. Some hinges have square corners; others have rounded corners with a particular radius. A replacement with a different corner shape may not sit neatly in the recess, called the mortise, cut into the door and frame.
Match the hinge type to the door
Most interior doors use standard butt hinges with two flat leaves joined by a pin. Some doors use hinges with removable pins, while others use fixed-pin hinges. Exterior doors may require security features, corrosion-resistant materials, or hinges designed for the door’s weight and exposure to weather. Check the existing hardware and the door manufacturer’s guidance, especially for an exterior or fire-rated door.
Also count the hinges and note where they sit. A typical interior door may have three, but the right number depends on the door’s weight and design. If you’re replacing several hinges, match the existing layout unless the door or hinge manufacturer recommends a change.
Tools and Preparation
Gather your tools before you start. You’ll usually need a matching hinge, a screwdriver or drill-driver with the correct bit, a hammer, a nail set or a slim punch, and a few wooden shims. A helper can make the job easier, but you can often manage a standard interior door alone if you support it securely.
- Replacement hinge and screws that suit the hinge and door
- Screwdriver or drill-driver, used gently
- Hammer and nail set or punch, if the hinge pin is removable
- Wooden shims or a door wedge to support the door
- Safety glasses, particularly when tapping out a pin
Work with the door open enough to reach the hinge, but not so far that it can swing freely. Put shims or a wedge under the door’s bottom edge. The support should take the door’s weight without forcing it upward; lifting the door too much can bind the hinge or make the screws difficult to align.
How to Replace a Door Hinge Step by Step
1. Decide whether to replace one hinge or remove the door
For a standard door, the simplest approach is usually to replace one hinge at a time. The other hinges keep the door attached to the frame, so you don’t have to lift the whole door off. This method works best when the replacement hinge matches the old one and its screw holes line up.
If you’re replacing every hinge, changing the hinge layout, or working on a heavy door, removing the door may give you better access. Get help with a heavy door. Doors can tip unexpectedly, and a falling door can injure you or damage the floor.
2. Support the door and remove the old hinge
Place the shims beneath the door near the hinge you’re replacing. If the hinge has a removable pin and you’re keeping the other hinge leaves attached, you may be able to tap the pin out and separate the hinge without unscrewing both leaves. Use a punch or nail set and tap gently upward from the bottom of the pin. Some pins are designed to come out from the top instead, so check how the hinge is made before tapping.
If the pin is fixed, or you’re replacing both leaves, loosen the screws on the hinge leaf you’re removing. Keep the door supported as the last screw comes out. If a screw is stuck, use the right-size screwdriver bit and press firmly so the head doesn’t strip.
3. Compare the old hinge with the new one
Before fitting anything, place the new hinge beside the old one. Check the overall size, corner shape, screw-hole spacing, thickness, and pin style. Open the new hinge fully and confirm that it moves smoothly.
If the shapes or holes don’t match, pause and find the correct hinge. Forcing a different hinge into the old recess can leave it sitting proud of the wood. That changes the door’s alignment and can make it bind or refuse to close.
4. Attach the new hinge leaf
Fit one leaf into the existing recess on the door or frame, depending on which side you’re replacing. The hinge should sit flat and level with the surrounding surface. Start the screws by hand or use a drill-driver on a low setting, then snug them up with a screwdriver.
A power driver can strip a screw head or drive a screw too far into the wood. Tighten each screw until the hinge is secure, but don’t keep turning once it’s firmly seated. If the old screw holes are sound and line up, they’re usually the easiest option to reuse.
5. Join the hinge and test the door
If you removed a pin, bring the two hinge leaves together and slide the pin back into place. Keep the door supported until the pin is fully seated and the screws are secure. Remove the shims slowly, then open and close the door several times.
Watch the gaps around the door. It should move without scraping, and the latch should meet the strike plate cleanly. If the door binds, stop rather than forcing it. A hinge may be sitting too high, a screw may be loose, or the replacement may not match the original dimensions.
What to Do About Stripped Screw Holes
A new hinge won’t stay tight if its screws can’t grip the wood. If a screw turns without tightening, the hole may be stripped. For a small interior-door hole, you can often repair it by removing the screw, filling the hole snugly with wooden toothpicks or a thin wood sliver coated with wood glue, and letting the glue dry. Trim the filler flush, then make a small pilot hole before reinstalling the screw.
If the damage is extensive, the door or frame wood is cracked, or the hinge carries a heavy door, a stronger repair may be needed. A solid wood plug or a repair plate can provide a better anchor. Don’t simply install a much larger screw without checking what’s behind the frame; long screws can encounter wiring or plumbing, depending on the wall and location.
For a sagging door, a longer screw at the top hinge can sometimes pull the hinge-side jamb closer to the framing. Only use this approach when the hinge and frame can accept the screw and you can reasonably rule out hidden services behind that spot. If you’re unsure, ask a carpenter or qualified handyman rather than guessing.
Common Mistakes to Avoid
- Letting the door’s weight hang on one hinge. Support it with shims before removing screws or pins.
- Buying a hinge based only on its color. Size, thickness, corner shape, and hole spacing matter more.
- Overtightening with a drill-driver. This can strip the wood or damage the screw head.
- Changing several hinges at once without support. The door can shift, fall, or become difficult to realign.
- Ignoring the reason the hinge failed. A warped door, damaged frame, or loose hinge-side jamb may need attention too.

Frequently Asked Questions
Can I replace a door hinge without taking the door off?
Often, yes. Replace one hinge at a time while supporting the door with shims, and leave the other hinges attached. If you’re replacing all the hinges or working with a heavy door, removing it with help may be safer and easier.
How do I know what size door hinge to buy?
Measure the old hinge when it’s open and flat. Check its height, width, thickness, corner shape, and screw-hole spacing, then compare those details with the replacement. Common sizes aren’t universal, so measurements are more reliable than guessing.
Do I need to replace all the hinges at once?
No. If only one hinge is damaged, replacing that hinge may be enough. Replace the others if they’re worn, rusty, bent, or visibly different from the new one—and make sure any replacements suit the door’s weight and use.
Why does my door still sag after I replace the hinge?
The screw holes may be stripped, the hinge-side frame may be loose, or the door itself may be warped. Check that every hinge sits flat and its screws are tight. If the frame is damaged or the door remains badly out of line, the problem may need a separate repair.
Conclusion
Replacing a door hinge is usually straightforward when you support the door, match the old hinge carefully, and work on one hinge at a time. Take a moment to check the screw holes and test the door before calling the job done. That little bit of care helps the new hinge sit flat, move smoothly, and hold the door securely.
