Moisture movement and wooden doors
Timber responds to its environment. Changes in moisture and temperature can affect clearances, edges and the way a door sits in its frame.

Moisture movement and wooden doorsThis doorset diagram supports moisture movement and wooden doors by showing the door, frame and hardware as connected parts of one opening.
Why timber doors can change slightly
A door that rubs seasonally does not always need replacement. The first step is to check the frame, hinges, clearances and signs of moisture before trimming anything. External exposure and bathrooms need particular attention to finishing and sealing.
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.
