How to hang a door

Removing the old door

Unscrew your old door. Take out the screws from the bottom hinge before the top hinge. If hinges or screws have been painted over, simply chip away the paint with an old screwdriver.
Make sure the door is well supported when you take the last screw out.

Cutting the new door to size
Hold the new door in the door frame to see if it needs adjustment.
If the old door was a good fit, use it as a template by laying it on top of the new door and marking where to plane or cut. Take an equal amount of wood from both the top and the bottom of the door to keep it in balance.
Use a panel saw if you need to take more than 6mm off the height of the new door. Then sand it smooth. If you’re trimming off less than 6mm, a hand or power plane is fine.
Ideally, there should be a 2mm gap on either side and at the top, between the door and the frame, when the door is in place – a two pence piece is a handy way to gauge this .
Allow 5mm-10mm at the bottom of the door if you have a thick carpet.

Fixing the hinges on the door frame

Check your new hinges fit against the old ones on the frame. If they don’t, rest them on the bottom of the existing hinge recess on the frame and mark along the top of the new hinge. Cut out the excess wood with a chisel and mallet. Check the new hinge sits comfortably and flush to the door frame.
Screw each hinge to the door frame with a single screw and open the hinges. The hinge pivots (edges) should stick out from the frame edge.
Prop the door in the door frame, resting it on wedges so there’s the correct gap at the bottom. With a pencil, mark where the top and the bottom of the hinges sit on the door .

Fixing the hinges on the door

Unscrew the hinges from the door frame and lay them on the edge of the door, making sure they’re lined up with your pencil marks (fig.4). Draw around the hinge flaps. Use a straight edge to mark the width of the hinge onto the door.
With a chisel and mallet, tap around the outline of the hinge shapes. Make sure the ‘bevel’ (sloped edge) of the chisel is facing towards the waste wood . Make a series of cuts across the wood at 5mm intervals to the same depth as the flap.
Check the hinges fit flush and fix with one screw per hinge. For this, use a screw or a bradawl a bit smaller than the screw to make a starter hole .

Helpful hint…
When you place the new door in the door frame, fix the hinges both top and bottom with just one screw. You can then check the new door opens and closes properly and make any adjustments before securing the other screws.

Hanging your new door
With the door supported on wedges and at right angles to the frame, fix the hinge flaps to the door frame. Use only one screw so you can make adjustments (
Check the door opens and closes easily. If it does, you’re ready to fix the rest of the screws .
