Step-by-step fix
Step 1: Set up the door and confirm the replacement
- Open the door just enough to reach the hinge comfortably.
- Place shims or a wedge under the door to support its weight.
- If the door is heavy, have another person steady it while you work.
- Compare the new door hinge to the old one. Match the height, width when open, corner shape, screw hole pattern, and handed fit if applicable.
- Score any paint line around the hinge with a utility knife before loosening screws.
If it works: The door is supported and the replacement hinge matches the old hinge closely enough to install.
If it doesn’t: Do not remove the old hinge yet. Get a closer match or plan for extra fitting work.
Stop if:- The door is too heavy to support safely.
- The new hinge is a different size or hole pattern and you are not prepared to adjust the mortise.
- The frame or door edge feels loose or cracked around the hinge area.
Step 2: Remove the old hinge carefully
- Work on one hinge at a time so the door stays aligned.
- Remove the screws from the hinge leaf on the door or frame first, then remove the screws from the other leaf.
- If the hinge has a removable pin and that is easier, tap the pin up gently and separate the leaves.
- Keep the old screws and hinge nearby in case you need them for comparison.
- Lift the old hinge out of the mortise and clear away dust, paint chips, or splinters.
If it works: The old hinge is off and the mortise area is clean and ready for the new part.
If it doesn’t: If a screw is stripped or stuck, stop forcing it. Try a hand screwdriver for better control or use screw-removal methods before continuing.
Stop if:- A screw spins without tightening because the wood is stripped.
- The hinge mortise is broken out or much larger than the new hinge.
- Removing the hinge causes the door to shift suddenly.
Step 3: Test-fit the new hinge in the mortise
- Set the new hinge into the existing mortise on the door and frame side.
- Check that it sits flat without rocking and that the edges line up closely with the old recess.
- Make sure the knuckle projects out enough for the door to swing freely and is oriented the same way as the old hinge.
- If paint buildup prevents a flat fit, scrape only the excess paint, not the wood.
- If the fit is slightly tight, trim only what is necessary and keep the mortise edges neat.
If it works: The new hinge sits flat in the mortise and lines up well enough for the screws to start straight.
If it doesn’t: If the hinge does not sit flat or the knuckle position looks wrong, remove it and recheck the hinge size and orientation.
Stop if:- The new hinge requires major cutting or repositioning you are not comfortable doing.
- The mortise is so damaged that screws will not hold securely.
- The hinge binds against the door edge before screws are installed.
Step 4: Install the new hinge and start screws by hand
- Place the hinge in position and start one screw by hand on the frame side and one on the door side to hold it in place.
- Add the remaining screws, starting each by hand to avoid cross-threading or crooked alignment.
- Tighten the screws snugly with a screwdriver. Use the drill only for light driving, then finish by hand for control.
- Keep the hinge leaf flat as you tighten so it does not pull out of position.
- If the hinge uses a removable pin, reinstall the pin fully once both leaves are secured.
If it works: The new hinge is mounted flat, the screws are snug, and the hinge pin is fully seated if applicable.
If it doesn’t: Back out any screw that goes in crooked and restart it by hand. If a screw will not tighten, the wood may need repair before the hinge can hold properly.
Stop if:- A screw head strips before it seats.
- The hinge leaf pulls away from the mortise as screws tighten.
- The door drops or twists while the hinge is only partly secured.
Step 5: Check door swing and alignment
- Remove the shims or wedge slowly and let the door rest on its hinges.
- Open and close the door several times.
- Watch the gap around the top and latch side for rubbing, sagging, or uneven spacing.
- Listen for squeaks and feel for binding near the replaced hinge.
- Retighten any slightly loose screws by hand.
If it works: The door swings smoothly, the gaps look even, and the hinge moves without obvious binding.
If it doesn’t: If the door rubs or sags, confirm the hinge is fully seated and that all screws are tight. Minor alignment issues may improve by reseating the hinge or replacing worn screws with proper-size screws that fit the hinge.
Stop if:- The door binds hard enough that forcing it could damage the frame.
- The hinge screws keep loosening because the wood no longer holds.
- The door is still badly out of alignment after the hinge is installed correctly.
Step 6: Finish up and decide if more repair is needed
- Wipe away dust and paint chips from the work area.
- If desired, add a small amount of hinge-safe lubricant to the pin after installation and wipe off excess.
- Check the other hinges for loose screws or visible wear so the new hinge is not carrying all the load.
- Save one old screw and the packaging from the new hinge for future matching.
- Plan a larger repair if the door frame, jamb, or mortise wood is damaged beyond a simple hinge swap.
If it works: The hinge replacement is complete and the door is ready for normal use.
If it doesn’t: If the door still does not operate normally, the problem may involve stripped wood, a shifted frame, or additional worn hinges.
Stop if:- The jamb is split or soft.
- Multiple hinges are bent or loose.
- The door is fire-rated, unusually heavy, or part of a setup you are unsure how to repair safely.

FAQ
Do I need to replace all the hinges at once?
Not always. If only one hinge is bent, cracked, or worn, you can replace that one. If the other hinges are loose, worn, or a different size, replacing them together can help the door stay aligned.
How do I know which door hinge to buy?
Match the old hinge as closely as possible. Measure the hinge height and open width, check whether the corners are square or rounded, compare the screw hole pattern, and make sure the hinge orientation matches the original.
What if the screw holes are stripped?
A new hinge will not solve stripped wood by itself. If screws will not tighten, the wood around the holes may need repair before the hinge can hold properly. Stop if the hinge feels loose after tightening.
Can I replace a hinge without taking the door down?
Usually yes, if you support the door well and replace one hinge at a time. Heavy doors can shift quickly, so get help if the door feels difficult to control.
Why does the door still rub after I replaced the hinge?
The new hinge may not be seated fully, the screws may not be tight, the replacement may not match the old hinge exactly, or another hinge may also be worn. Frame movement or damaged wood can also keep the door out of alignment.
