Reuse, repair or replace a door?
Door problems are easier to solve when the leaf, frame and hardware are assessed separately. One failed component does not automatically mean replacing everything.

Reuse, repair or replace a door?This adjustment diagram supports reuse, repair or replace a door? by focusing on the door-to-frame relationship that is checked before deciding whether repair or replacement is appropriate.
Start with the condition, not the assumption
Reuse what is sound, repair what can be restored reliably, and replace parts that no longer suit the opening or required function. This keeps the scope proportionate to the actual problem.
What to look at
Start with the opening, the condition of the existing door and frame, the way the space is used, and the finish you want to achieve. These details usually narrow the practical options quickly.
