How Often Should You Paint Your House Exterior in Arizona?
Arizona sun eats paint faster than almost anywhere in the country. Here's how often to repaint a stucco home in Phoenix — and the signs you're overdue.

The short answer for Phoenix homeowners
In most parts of the country, a quality exterior paint job lasts 10-15 years. In the Phoenix metro, cut that in half. A properly prepped, two-coat repaint using a top-tier product like Sherwin-Williams Emerald Exterior holds up 7-10 years on stucco. Mid-grade paint on a poor prep? 3-5 years, and the south and west walls will fail first.
If your last exterior paint job was more than 7 years ago, it's worth walking the house and checking the sun-facing walls closely.
What shortens the timeline in Arizona
Three factors matter more than paint brand: hours of direct sun (west and south elevations fade fastest), stucco condition (hairline cracks let moisture in and lift paint from behind), and coat count (one-coat jobs are effectively half the lifespan).
Two-story homes and homes without mature landscaping shading the west wall usually need a repaint 1-2 years sooner than a shaded single-story.
Signs you're overdue
Chalking (a powdery film that comes off on your hand when you rub the wall) is the earliest sign. Fading — where the south/west walls are visibly lighter than the north/east — is the next stage. Peeling, cracking around windows and eaves, and visible stucco hairlines mean you're already past due and prep costs will be higher.
Once you see bare stucco showing through, UV is now degrading the substrate itself. That's when small repaints turn into large ones.
How we stretch the interval
Every exterior we do gets a full prep-first workflow: pressure wash, stucco crack repair, efflorescence treatment, spot-prime bare areas, then two full coats of Sherwin-Williams Emerald Exterior. That combination is what buys you the 8-10 year interval instead of 4.
