How to fix loose screws on door hinge?

Screws are not "biting" properly. Use the same size screws but at least half an inch longer. Before screwing them in, fill the existing hole with a piece of timber trimmed down to just fit the holes. This will do it for ever.

not sure what side of the hinge the screws are loose on the door or frame.if on the frame side, try putting the wood splinters/tooth picks in again but this time also insert some gorilla glue in the hole first.don't know what size screw you are using but you need one long enough to reach into the framing of the door way at least 3"screws should do it. you could also replace the trim .if on the door itself reset the hinges.a little more work but it would be a better and more permanent fix.and use a wood filler to fill in the old hinge positions

Fill the screw holes with car body type filler and re-fix. Make sure you have decent length screws maybe a couple of inches, and use duo thread or Pozidriv types for extra holding strength. You might consider fitting an additional hinge to spread the load, in the middle.

A decent wood filler would help - or you could move the hinges a little bit up/down so the screws are going into fresh wood.

Could be the screws are not 'man' enough for the job. New hinges and screws or maybe a lighter door?

Luck

assuming your door is in correct position and you wish to maintain the same screw holes then:

remove the door and hinges from your door jamb.

drill a pilot hole neatly up the old screw holes about 35mm deep. then drill the finish size hole using a Ø13 drill (or the same size drill as a hardwood dowel that you can purchase from the hardware) to the same depth.

fit your dowel plugs using some wood glue. they should be a fairly tight fit. you may need to make a chamfer on the edge that is entering the hole to assist with the insertion.

leave the dowels dry overnight.

drill a Ø2mm pilot hole in the top middle hinge ( may need to use door to find this) it should be exactly in the center of your dowel plugh if you worked accuraetly.

do same to lower hinge.

check operation of door,

if good operation of door is seen then now drill pilot holes and fit the remaing screws to other holes for hinge srews anchors.

I was going to suggest to cut little pices of wood in the shape of an arrow head.glue on it and firmly pound it in.No need for larger screw.thats too late I guess.You don't want to go rounder.However a longer screw will go thru jamb and make contact with the 2x4 framing material.Be carefull if you try this.Upon contact with the 2x4 you must tighten by hand or you may end up with a badly adjusted door.Then it won't close right.Good Luck.If this does not work.Tell the kids to stop hanging on it.

The best thing to do is to use plastic plugs the same type used for concrete wall. Poking little splinters into the holes like you did help but will not last. Use drill to widen the hole to fit the plug if you need to. For extra holding power, apply glue to the plug, wait to dry before screwing the door hinge back to position.

Only one person had it right. You need at least one screw per hinge, usually the middle screw, that is long enough to penetrate the wall framing behind the door jamb. Half inch longer may not be long enough. You may want to try 2" screws. Same diameter as the originals.

Probebly the door is just too heavy for the hinges and screws you are using.

Try bigger hinges or add an two additional hinges in the central portion of the door
