Average Paint Lifespan by Surface

While results vary, typical ranges include:

Interior walls: 5–10 years
Interior trim & doors: 7–10 years
Exterior siding: 5–10 years
Exterior trim: 3–7 years

What Affects How Long Paint Lasts?

Key factors include:

Surface preparation quality
Paint type and finish
Exposure to sunlight, moisture, and temperature changes
Cleaning methods and frequency
Daily wear and use

This is why professionally completed interior painting and exterior painting projects typically last longer than DIY work.

Signs Paint Is Near the End of Its Life

Common indicators include:

Fading or discoloration
Peeling or bubbling
Cracking or chalking
Repeated touch-ups that no longer blend
