How Long Does Exterior Paint Last?
By Dunwoody Painters ·
Expected lifespan by siding type in metro Atlanta, and the variables that cut it in half.
In metro Atlanta, a professional exterior repaint lasts 7 to 10 years on most homes. Substrate makes the biggest difference.
Lifespan by siding type
| Substrate | Expected lifespan |
|---|---|
| Fiber cement (HardiePlank) | 10–15 years |
| Stucco | 8–12 years |
| Brick (painted) | 8–12 years |
| Wood siding | 5–8 years |
| Aluminum / vinyl | 8–10 years |
| Trim and fascia | 5–7 years |
What shortens it
- Sun exposure. South and west elevations fade and chalk years before the shaded sides.
- Tree cover and shade. Constant damp encourages mildew — the flip side of the same problem.
- Poor prep. Painting over chalk, dirt, or failing paint is the number one cause of early failure.
- Failed caulk. Once water gets behind the film, peeling follows fast.
- Thin coverage. One coat sprayed without back-brushing rarely reaches proper film thickness.
Signs you need a repaint now
- Chalky residue on your hand when you rub the siding.
- Peeling, blistering, or bubbling anywhere.
- Visible bare wood or exposed caulk joints.
- Mildew that returns within weeks of washing.
- Noticeable fading on one elevation compared with another.
Getting the maximum life
Wash the exterior annually to remove pollen and mildew, inspect and re-caulk joints every two to three years, keep gutters flowing so water doesn't sheet down siding, and trim vegetation back at least a foot from the walls.
