Arizona’s harsh climate takes a toll on exterior paint. Knowing when it’s time for professional exterior painting helps you protect your home before minor issues become major problems. Here are five clear signs your Phoenix home needs a fresh coat.
Sign #1: Chalking
What It Looks Like
Rub your hand across your exterior wall. If it comes away with a chalky, powdery residue, your paint is breaking down.
Why It Happens
UV radiation from Arizona’s intense sun breaks down paint resins over time. The pigments that were once bound together become loose powder.
What It Means
- Paint has lost its protective properties
- Color will continue to fade rapidly
- Surface is vulnerable to moisture
- Repainting should be done within 6-12 months
DIY Test
Run a dark cloth across the wall. Heavy white residue indicates significant chalking that requires attention.

Sign #2: Fading and Color Loss
What It Looks Like
Compare areas of your exterior:
- Shaded vs. sun-exposed walls
- Areas under eaves vs. open walls
- North-facing vs. south-facing surfaces
Why It Happens
UV radiation breaks down color pigments. South and west-facing walls in Phoenix can fade significantly within 3-4 years, even with quality paint.
What It Means
- Aesthetic appeal has diminished
- Paint resins are also degrading
- Protection is compromised
- Curb appeal affects home value
The Color Hierarchy
Colors fade at different rates:
- Reds and yellows - Fade fastest
- Blues and greens - Moderate fade rate
- Whites and neutrals - Most stable
Sign #3: Cracking and Peeling
What It Looks Like
Hairline Cracks Fine surface cracks, often at corners and stress points.
Alligator Cracking Pattern resembling alligator skin, indicating deeper failure.
Peeling Paint lifting away from the surface in sheets or flakes.
Why It Happens
- Temperature expansion and contraction
- Paint losing flexibility with age
- Moisture beneath the paint film
- Poor original preparation
What It Means
Hairline cracks: Address within 6 months Alligator cracking: Address soon - moisture risk high Peeling: Urgent - substrate exposed to elements
Warning
Once peeling begins, it spreads rapidly. The exposed edges curl and lift more paint with each temperature cycle.

Sign #4: Stucco Damage Showing Through
What It Looks Like
- Visible cracks in the stucco itself
- Exposed brown or gray stucco color
- Chips and gouges
- Areas where paint has worn through
Why It Happens
- Physical impact damage
- Extreme weather events
- Normal wear at high-traffic areas
- Age and settling
What It Means
This is a two-part problem:
- Stucco needs repair
- Paint needs renewal
Important
Painting over damaged stucco is a waste of money. Repairs must be made first for paint to adhere properly and provide protection.
Sign #5: Mold, Mildew, or Staining
What It Looks Like
- Dark spots or patches
- Greenish or black discoloration
- Streaking below roof lines
- Spots that don’t power wash away
Why It Happens
- Moisture accumulation (sprinklers hitting walls)
- Shaded areas with poor air circulation
- Failed paint allowing moisture penetration
- Roof drainage issues
What It Means
Beyond aesthetics:
- Potential health concerns
- Substrate damage possible
- Root cause must be addressed
- Fresh paint alone won’t solve it
The Fix
- Identify moisture source
- Correct underlying issue
- Kill mold/mildew properly
- Apply mildew-resistant paint

When Multiple Signs Appear Together
If you’re seeing several of these signs, don’t delay. Multiple symptoms indicate:
- Paint has reached end of life
- Further delay causes more damage
- Repair costs increase over time
- Home value continues declining

- Maintain regularly - Annual inspections catch issues early
The Cost of Waiting
Delaying necessary repainting costs more in the long run:
