Step-by-step fix
Step 1: Make sure the hinge is really the problem
- Open and close the door slowly and watch the gap around the door slab.
- Look for a hinge leaf that is bent, cracked, pulling away from the jamb, or worn enough that the door sags.
- Check whether the screws are stripped or loose first, because sometimes tightening or replacing screws solves the problem without replacing the whole hinge.
- Measure the existing hinge height and width, and note whether the corners are square or rounded.
- Buy a matching front door hinge before removing the old one.
If it works: You have confirmed the hinge is damaged or worn and you have a replacement that matches the old hinge.
If it doesn’t: If the hinge looks sound and the problem is only loose screws, try repairing the screw hold first instead of replacing the hinge.
Stop if:- The door frame wood is split, soft, or badly rotted around the hinge area.
- The door is dragging because the frame has shifted or the slab is warped rather than because of a bad hinge.
- The replacement hinge does not match the size or corner style of the old one.
Step 2: Support the door and prep the work area
- Close the door until it is almost shut, leaving just enough room to reach the hinge comfortably.
- Slide wood shims or wedges under the outer edge of the door until the door feels supported and does not drop when you lift lightly on the handle.
- If paint bridges the hinge edges, score around the hinge with a utility knife.
- Keep one hand on the door as you test that the shims are carrying the weight.
If it works: The door is stable, supported from below, and ready for one hinge to come off safely.
If it doesn’t: Add or adjust shims until the door no longer shifts when you remove pressure from the hinge.
Stop if:- The door is too heavy to control safely by yourself.
- The door moves sharply or drops even with shims in place.
Step 3: Remove the old hinge one side at a time
- Work on only one hinge at a time so the other hinges help hold alignment.
- Remove the screws from the hinge leaf on the door or jamb, then remove the screws from the other leaf.
- Pull the old hinge out of the mortise and keep one old screw nearby in case you need it to compare length and thread.
- Clean out dust, paint chips, and loose debris from the hinge recess.
If it works: The old hinge is out and the mortise is clean enough for the new hinge to sit flat.
If it doesn’t: If a screw will not back out cleanly, apply steady pressure with the correct bit and try again before the screw head strips.
Stop if:- A screw head strips badly and cannot be removed with normal hand tools.
- The wood behind the hinge is crumbling or too damaged to hold new screws securely.
Step 4: Install the new front door hinge
- Set the new hinge into the mortise and make sure it sits flush without rocking.
- Start the screws by hand first so they thread straight and do not cross-thread or pull the hinge out of position.
- Tighten the screws snugly, alternating between top and bottom screws so the hinge leaf stays flat.
- If the hinge includes longer screws, use them only where they fit properly and draw the hinge tight without forcing the wood.
- Open the door a few inches and close it again to make sure the hinge knuckle moves freely.
If it works: The new hinge is mounted flat, secure, and moving smoothly.
If it doesn’t: If the hinge will not sit flush, remove it and check for paint buildup, debris, or a mismatch in hinge size or corner shape.
Stop if:- The new hinge binds immediately because it does not match the old hinge layout.
- The screws spin without tightening, showing the wood is stripped and needs repair before the hinge can hold.
Step 5: Fine-tune the alignment
- Remove or lower the shims gradually and let the door settle onto the hinges.
- Open and close the door several times and watch for rubbing at the top, latch side, or threshold.
- Snug the hinge screws again if the hinge shifted slightly during settling.
- If the door is still slightly out of line, check the other hinges for loose screws so the new hinge is not trying to correct the whole door by itself.
If it works: The door swings with an even feel and the gaps look close to normal.
If it doesn’t: If the door still sags or rubs after the new hinge is secure, inspect the remaining hinges and screw holes for wear or damage.
Stop if:- The door remains badly out of square after the hinge replacement, suggesting a frame or door alignment problem beyond a single hinge.
Step 6: Test the repair in normal use
- Open the door fully, then close it several times at normal speed.
- Check that the latch lines up and catches without lifting, pushing, or slamming the door.
- Listen for grinding, popping, or metal-on-metal rubbing at the new hinge.
- Look at the hinge screws one last time to make sure none backed out during testing.
If it works: The door opens, closes, and latches normally, and the new hinge stays tight under real use.
If it doesn’t: If the door still does not latch cleanly, recheck hinge fit, screw tightness, and the condition of the other hinges before moving on to latch adjustments.
Stop if:- The hinge loosens again right away or the door still drops, which usually means the surrounding wood or another hinge needs repair too.

FAQ
Can I replace just one front door hinge?
Yes, if only one hinge is bent, cracked, or badly worn. Replace one hinge at a time so the door stays supported and aligned as you work.
How do I know which hinge to buy?
Match the old hinge by height, width, corner style, finish, and handedness. A hinge that looks close but is not an exact match may not sit flush or line up correctly.
What if the new hinge screws will not tighten?
That usually means the wood screw holes are stripped or damaged. The hinge needs solid wood behind it, so repair the screw hold before expecting the new hinge to stay tight.
Do I need to remove the whole door to replace a hinge?
Usually no. For a single hinge replacement, supporting the door from below and changing one hinge at a time is often enough.
Why does the door still rub after I replaced the hinge?
A worn hinge can be only part of the problem. Check the other hinges, loose screws, damaged wood at the jamb, and whether the frame or door slab has shifted.
