How long does a wood exterior door last?
You can expect a wood exterior door to last 30 to 70+ years, with an average of 50 years. The are three factors that affect door longevity:
1) Weather exposure - A door under only a small roof overhang above it that is exposed to direct sun and driving rain will have a shorter life than one recessed on a deep entry porch, like the door shown above.
2) Type of wood - Hardwoods last longer. So pine will be at the lower end of the age range and mahogany at the upper end.
3) Paint or other sealer coating - Maintaining a protective coating on the door will extend its life.
Also, drywood termites can infest and destroy a wood door in areas like Florida where they are prevalent. Here’s a bar graph that compares the life expectancy of a wood exterior door to other types of residential doors.

NOTE: These life expectancies are based on data provided by InterNACHI, NAHB, FannieMae, and our own professional experience. Because of the numerous variables that can affect a lifespan, they should be used as rough guidelines only, and not relied upon as a warranty or guarantee of future performance.
