How to replace a door

Marking the new door

Laying the old door on work stools 

The old door was stripped of all its hardware (hinges and lockset) and placed on a pair of work stools.

Note: The replacement door should be the same size or slightly bigger than the old door. A slightly bigger door can be cut down or shaved to suit.
If the replacement door has to be cut down or shaved to replicate the shape of the old door, make sure that there is enough solid wood to allow for cutting/shaving without weakening the structure of the door.

Laying the new on top of the old

The new door was slightly bigger than the old door. It was placed on top of the old door so the exact shape of the old door could be marked onto the new one.

The new door was taken off, shaved to the same shape as the old door, placed back on top the old door and clamped firmly in place.

Marking for the hinges

The edges of the new door were flush with the edges of the old door.

Using a square and a ruler, the hinge positions on the old door were copied to the new door.

Marking for the latch

Using a square and a ruler, the latch position on the old door was copied to the new door.
