There is no single number that fits every house. How often you need to repaint an exterior depends on your siding, your color, and how much sun and weather that side of the home takes. In the Sacramento climate, intense UV tends to be the deciding factor.
Use these general timelines as a starting point, then let the walls tell you the rest.
Typical timelines by siding
Stucco: roughly 7–10 years with a quality coating, longer if it was prepped and sealed well.
Wood & fiber-cement: about 7–12 years, though trim and south-facing walls fade first.
Previously dark or low-grade paint: often 5–7 years, because dark colors and cheaper paint break down faster in the sun.
Signs it is time, regardless of the calendar
Paint usually warns you before it fails. Look for fading or a color that looks washed out, a chalky residue that rubs off on your hand, hairline cracking or peeling, and caulk that has pulled away from trim and windows. Any of these means the coating is losing its ability to protect the surface underneath.
Walk the sunniest side of your home once a year. It ages fastest, so it is your early-warning system for the whole exterior.
Why repainting on time saves money
Exterior paint is not just cosmetic — it is your home's weather barrier. Repaint while the old coat is merely tired and prep is quick and inexpensive. Wait until it is cracked and peeling, and you add hours of scraping, sanding, and repair, plus the risk of water reaching the substrate.
The bottom line
Plan on repainting stucco every 7–10 years and other sidings on a similar cycle, but trust what you see. Fading, chalking, and cracking are the real signals — and catching them early keeps the job smaller and the house protected.
