How long does paint last on a house?

Interior paint lasts 5–10 years for bedrooms and living areas, 3–5 years for high-traffic rooms (kitchen, bathroom, kids' rooms, hallways). Trim, doors, and ceilings typically run 8–12 years. Exterior paint lasts 5–8 years on wood siding, 7–10 years on fiber-cement, and 8–15 years on stucco/masonry. Climate matters more than brand: South Florida and Gulf Coast (heat + humidity + UV) cut exterior life roughly in half versus Pacific Northwest. Premium paints (Sherwin-Williams Emerald, Benjamin Moore Aura) cost 30–50% more per gallon but stretch refresh cycles 25–40%.
