How to change door & window furniture

With the door held open, remove the old door handles. Any screw holes in the door that will not be covered by the new handles will need to be filled, sanded and painted over.

Replace the old spindle with the new one.

Gently push the new handles into place. If they don’t touch the door on both sides, the new spindle is too long and will need to be cut to length with a hacksaw.

Use a spirit level to check the sides of the handles are vertical.

Mark the position of the new screw holes with a carpenter’s awl.

Remove the door handles and drill pilot holes.

Finally, screw the handles into place using the provided screws. Take care not to scratch the handles when fixing them.

Unscrew the old knob or handle. If possible, plan the position of the new handle so you can re-use or cover the existing holes. Otherwise, these will need to be filled, sanded and painted over.

Measure between the centres of the two holes on the new handle – this distance may be stated on the packaging.

Mark the position of where the two holes will be on the front of the door. Connect the marks with a spirit level to check that the handle will be exactly vertical.

Clamp a block of wood behind the door, then use a suitable drill bit to drill two holes through the marks into the block. Remove the clamp and smooth the hole with sandpaper if necessary.

Finally, fix the handle into place using the screws supplied.

Remove the old casement fastener and mortice stop (or hook). Re-use the existing holes if possible. Otherwise, these will later need to be filled, sanded and painted over.

If you need to make new holes, place the fastener in position, with its catch in the mortice (hole) if possible. Then, use a pencil to draw two pilot hole guide marks.

Open the window so that the drill doesn’t mark the frame, then drill the pilot holes. Close the window and screw the fastener into place with the provided screws.

If the catch doesn’t fit into the existing mortice, use a chisel to adjust the hole as necessary.

When the catch fits, position the new mortice stop, mark and drill two pilot holes and secure it in position with the provided screws.

Remove the old casement stay and pegs. Re-use the existing holes if possible. Otherwise, these will later need to be filled, sanded and painted over.

To make new holes, put the stay into position, then use a pencil to draw guide marks for two pilot holes.

Open the window so that the drill doesn’t mark the frame, then drill the pilot holes.

Close the window, position the stay and secure it in place with the provided screws.

Then, put the two pegs into position, through the first and last holes on the stay, and adjust them slightly so the stay can rise and fall without knocking the pegs.

Use a pencil to draw the pilot hole guides for the first peg, drill, then secure the peg in position with the provided screws. Double-check the position of the second peg before fixing it in the same way.
