Step-by-step fix
Step 1: Confirm hinge screws are the real problem
- Open and close the door slowly and watch the hinge side.
- Look for loose screw heads, missing screws, hinge leaves pulling away from the jamb, or a door that drops slightly when you lift the handle side.
- Check whether the rubbing or latch misalignment gets better when you tighten one or two loose hinge screws by hand.
- Make sure the hinge itself is not bent or cracked before you focus on the screws.
If it works: You have confirmed the door problem is tied to loose, stripped, missing, or undersized hinge screws.
If it doesn’t: If the screws are tight and the problem is really a bent hinge, swollen door slab, damaged frame, or latch alignment issue, fix that problem instead of replacing screws first.
Stop if:- The wood around the hinge is soft, rotten, split deeply, or crumbling.
- The hinge leaf or jamb is cracked badly enough that screws will not hold.
- The door frame is shifting or the door is dragging because of structural movement.
Step 2: Support the door and match the replacement screws
- Close the door or leave it barely open in a stable position.
- Slide a shim or wedge under the latch side until the door is lightly supported and the hinge is not carrying all the weight.
- Remove one existing hinge screw and compare its length, thickness, head shape, and drive type to your replacement screws.
- Plan to replace screws one hinge at a time so the door stays aligned.
If it works: The door is supported and you have replacement screws that fit the hinge countersinks and thread into solid wood.
If it doesn’t: If the new screw heads do not sit neatly in the hinge holes, get the correct head style before continuing.
Stop if:- The door shifts suddenly when one screw is removed and cannot be supported safely by a shim alone.
Step 3: Remove the worst screws first
- Start with the top hinge, since that hinge usually does the most work on a sagging exterior door.
- Remove one loose or stripped screw at a time instead of taking all hinge screws out at once.
- If a screw spins without backing out, pull gently on the hinge leaf while reversing the screw to help it catch enough to come free.
- Set aside any damaged screws so they do not get mixed back in.
If it works: The damaged or loose screws are out and the hinge is still held in place by the remaining screws.
If it doesn’t: If a screw head is stripped, use a hand screwdriver with firm pressure or a screw extractor before damaging the hinge further.
Stop if:- The hinge leaf springs away from the jamb because the surrounding wood has failed.
- Removing the screw exposes a void or severe damage behind the hinge.
Step 4: Tighten the screw holes and install the new screws
- If a hole is only slightly stripped, add a few glue-coated toothpicks or wood splinters, tap them in snugly, and trim them flush.
- Drive the new screw straight through the hinge and into the repaired or existing hole.
- Snug the screw until the hinge leaf pulls tight to the jamb, then finish by hand so you do not strip the hole again.
- Repeat for the remaining bad screws on that hinge, then move to the next hinge as needed.
- If the door has been sagging, replace at least one top-hinge jamb screw with a longer screw that reaches solid framing, as long as it fits the hinge properly.
If it works: The hinge leaf sits flat, the screws are snug, and the door feels more solid at the hinge side.
If it doesn’t: If a screw still will not tighten, the hole may be too damaged for a simple screw swap and may need a more substantial wood repair.
Stop if:- The screw keeps spinning with no bite even after a minor hole fill.
- The jamb wood splits as the new screw goes in.
Step 5: Align the door and finish replacing the remaining hinge screws
- Remove the shim and test the door swing after the top hinge is tightened.
- Replace any other loose, rusted, or mismatched hinge screws one at a time on the middle and bottom hinges.
- Tighten all hinge screws evenly so the hinge leaves sit flat without gaps.
- Wipe away any glue squeeze-out if you used a simple hole fill.
If it works: All needed hinge screws are replaced and the door hangs more evenly than before.
If it doesn’t: If the door still sags after the screws are secure, recheck for a bent hinge, worn hinge mortise, or frame movement.
Stop if:- The door alignment gets worse as screws are tightened, which can point to a deeper frame or hinge placement problem.
Step 6: Verify the repair in real use
- Open and close the door several times from fully open to fully shut.
- Check that the door no longer rubs at the top corner, threshold, or strike side the way it did before.
- Lock and unlock the door to make sure the latch and deadbolt still line up without lifting or pushing the door hard.
- Look at the hinge leaves one last time to confirm they stay tight against the jamb after repeated use.
If it works: The door swings smoothly, closes normally, and the new hinge screws stay tight under normal use.
If it doesn’t: If the screws loosen again quickly, the wood behind the hinge is likely too damaged for replacement screws alone and the jamb may need repair.
Stop if:- The door still will not latch or drags badly even though the hinges are tight, suggesting the wrong repair path or a larger alignment issue.

FAQ
Do I need to replace every hinge screw?
No. Replace the loose, stripped, rusted, or mismatched screws first. If several screws are worn or the door has been sagging for a while, it often makes sense to replace the full set on the affected hinges so they match and hold evenly.
What length hinge screws should I use on an exterior door?
Use screws that match the hinge properly and are long enough to bite into solid wood. Short screws may only grab the jamb surface. On many sagging exterior doors, one or more longer screws at the top hinge help pull the jamb side tight to the framing.
Can I just tighten the old screws instead of replacing them?
If the screws are still in good shape and tighten firmly, yes. Replace them when the heads are damaged, the threads no longer hold, they keep backing out, or they are too short to support the door well.
What if the screw hole is stripped?
A mildly stripped hole can sometimes be tightened with a simple wood-filler trick like glue-coated toothpicks or wood splinters. If the hole is badly wallowed out or the wood is split or rotten, the jamb usually needs a more solid repair than new screws alone.
Why start with the top hinge?
The top hinge usually carries the most stress on a sagging door. Tightening or replacing those screws first often gives the biggest improvement in alignment and helps pull the door back into position.
