How Long Should Exterior Paint Last in the Dallas Heat?

Warranty language on a paint can assumes an average climate. Dallas is not average. We get intense summer UV, wide day-to-night temperature swings that constantly expand and contract siding, and hail that physically damages the film.

Realistic service life by surface

• Fiber cement siding: 10–15 years, the longest-lived surface on most modern homes.
• Stucco and masonry: 8–12 years with a breathable acrylic system.
• Wood siding and trim: 5–8 years, less on south and west elevations.
• Fascia, soffits, and window sills: 4–7 years — these fail first almost every time.
• Front doors in direct sun: 3–5 years before the finish chalks or fades noticeably.

Why the west side always goes first

Afternoon sun in July puts surface temperatures on a west-facing wall well over 130°F. UV breaks down the resin binder, the pigment loosens, and you get chalking and fading years ahead of the shaded elevations. It's normal, and it's why we sometimes recommend a partial repaint of the sun-exposed sides between full cycles.

Stretching the interval

Wash the exterior once a year to remove chalk and mildew, re-caulk failing joints as soon as you spot them, keep sprinklers off the siding, and trim shrubs back so walls can dry. Those four habits routinely add two or three years to a paint job in North Texas.
