Remove the old door.
First job is to unscrew the old door first, removing the screws from the bottom hinge before the top hinge.
Make sure the door is well supported when the last screw is taken out of the top hinge then remove the old door out of the way.
Cutting the new door to size.
Offer the new door up, if it needs trimmed make sure you take an equal amount of wood from both the top and the bottom of the door to keep it in balance.
If the new door is to wide only take cuts from the hinge side.
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 need to trim off less than 6mm, use a hand or power plane.
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 2 pence piece is a good gauge for this.
Allow 5-10mm at the bottom of the door if you have a thick carpet.
Fix door hinges to door frame.
try and match your new hinges with the old ones on the frame. If they don't, rest the new ones 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 if any with a chisel and mallet. Checking the 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 pivot edges should stick out from the frame edge.
Now 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.
Lay the hinges on the edge of the door, making sure they're lined up with your pencil marks. 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. Mak 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 screws.
Hang the 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 any adjustments if needed . Check the door opens and closes easily. If it does, you're ready to fix the rest of the screws.
Fixing the door furniture.
First, fit the latch. The latch is usually set into the middle of the side of the door about 1m from the bottom of the door to the bottom of the latch plate.
Mark this on the edge of the door. Hold the latch in place in the centre of the edge of the door. Draw around it with a pencil to mark its position on the door. Choose a flat wood cutting drill bit that's slightly bigger than your latch so there's enough room to fit the latch in the hole.
To measure the depth of the latch hole, hold the latch against the drill bit. I use masking tape to mark the depth of the latch on the bit. Wedge the door open and drill the hole into the side of the door to this depth then insert the latch.
Make sure it's level and mark around its position. With a chisel, make a series of cuts on the edges of your pencil outline. Then chisel out the rest of the recess.
Check the fit to see if the latch plate lies flush with the door.
Making a hole for the spindle. Take the latch out and hold it in position on the outside of the door next to the hole made for it. Put your pencil through the hole in the latch and make a mark. This is where the handle spindle will go.
Mark this on both sides of the door.Choose a drill bit 2mm wider than the spindle and start drilling. When the drill bit begins to emerge through the other side of the door, start drilling from that side to stop the wood splitting.
When you've finished drilling, remove any debris from the hole. Slide the latch back into the door. Place the spindle into its hole and then screw the latch into place.
Place a handle onto the spindle. Use one hand to hold the handle in place. With the other, drill in the screws for the back plate. Give the handle a quick test. Repeat the process on the other side of the door for the other handle.
Fixing the latch plate on the door frame. The latch plate is the piece of metal that slots into the door frame.
Close the door so the latch touches the frame. Mark its position on the door frame. This gives you the height of the latch plate. To find the horizontal position of the latch plate, measure the distance between the edge of the latch and the edge of the door. Transfer this measurement to the door frame and mark with a pencil at the height you marked. Draw in and around the latch plate. Following your marks, chisel out the recess for the latch plate so it fits flush with the door frame. Screw the latch plate onto the frame.
The new door is now ready for stain or painting.
