How long does exterior paint last?
Updated August 2026
Exterior paint lasts 5–10 years, and the surface underneath moves that number far more than the brand on the can. Paint over wood siding goes 3–7 years because wood swells and shrinks with every wet season; stucco holds 5–10; fiber cement reaches 10–15 because the board barely moves at all. Two forces then decide where a given wall lands: direct sun, since UV breaks down the binder and chalks the finish, and the quality of the prep. A 100% acrylic latex over scraped, primed, dry siding routinely doubles the life of the identical paint rolled onto a dirty wall.
Lifespan by type and situation
| Type or situation | Typical lifespan | Why |
|---|---|---|
| Wood siding and trim | 3–7 years | Moves with moisture, so the film cracks and peels first |
| Cedar shakes and shingles | 5–8 years | Stain soaks in and weathers rather than peeling; recoat sooner |
| Stucco | 5–10 years | Masonry paint holds well until hairline cracks start opening |
| Fiber cement, field painted | 10–15 years | Dimensionally stable; the caulk lines fail before the paint does |
| Fiber cement, factory finish | 15–25 years | Baked-on coatings carry 15-year and longer warranties |
| Brick and masonry | 8–15 years | Long-lasting, though a breathable masonry paint is mandatory |
| South and west elevations | Cut 2–4 years | Afternoon UV chalks and fades those walls years ahead of the rest |
| Skipped prep, no scrape or primer | Cut 3–5 years | The new coat bonds to the old failing layer, not to the siding |
Signs yours is near the end
- A chalky residue that comes off on your hand when you rub a sunny wall
- Peeling, flaking, or blistering, worst on south and west walls and under the eaves
- Hairline cracking or alligatoring across the paint film
- Uneven fade, with the shaded north side still looking close to new
- Caulk lines that have shrunk, split, or pulled away from trim and window frames
- Bare wood showing at corners, sills, and the bottom edges of boards
How to add years
Prep buys the lifespan and washing protects it. Rinse the siding once a year with a garden hose and a soft brush to strip the pollen, dirt, and mildew that hold moisture against the film; a pressure washer on a tight tip drives water behind the boards and does more harm than good. Touch up bare spots and re-caulk split joints as they show, because water entering at one window sill peels a whole section by the next spring. When the full job arrives, do not skip the boring parts: scraping, sanding, spot-priming, and two coats of 100% acrylic latex is the entire difference between 5 years and 10. Letting peeling paint run for a few seasons exposes bare wood, and rotted siding turns a $3,000–8,000 repaint into a $10,000-plus siding job. Timing sits on how often to repaint an exterior, and the yearly steps are on the exterior paint maintenance checklist.
What it costs to replace: plan on $3,000–8,000 for a full repaint. Replacing on your own schedule, before it fails, is almost always cheaper than the emergency version. The home maintenance cost calculator helps you set the money aside before it comes due.

How do I know if my house needs repainting or just a wash?
Run your hand along a sunny wall. If it comes back chalky but the paint is otherwise intact, the house needs washing and probably has 1 to 3 years left. If you find peeling, cracking, or bare wood, washing only spreads the failure, and it is time to scrape and repaint. A useful middle path is elevation-by-elevation work: paint the south and west sides, which always fail first, and leave the shaded walls for the next cycle. That splits a $6,000 job into two manageable ones.
Is premium exterior paint worth the extra cost?
Yes, more than almost any other decision in the project. A premium 100% acrylic latex costs $55 to $85 a gallon against $30 to $40 for builder grade, so upgrading a whole house adds maybe $300 to $600 in material on a job where labor is 80% of the bill. The better resin holds color and flexes with the siding, which commonly buys 3 to 5 extra years. Paying two-thirds of the labor again in year 6 to save $400 in year 1 is the wrong trade.
What time of year should you paint a house exterior?
Late spring through early fall, on a stretch with daytime temperatures between 50 and 85 degrees and no rain forecast for 24 to 48 hours after. Most acrylic latex needs at least 50 degrees to form a proper film, and low-temp formulas go down to about 35. Avoid painting a wall in direct afternoon sun, which flashes the surface dry before it can bond, and stop early enough that evening dew does not settle on a fresh coat. Follow the shade around the house.
