Siding · Stucco
How long does stucco last?
The NAHB's 2007 life-expectancy study gives stucco 50 to 100 years, and stucco earns that spread honestly: it is the same cement-and-sand recipe that has outlasted centuries of buildings, and it is also the cladding with the worst moisture record of the last thirty years. There is no warranty bar here, because a stucco wall is not a product anybody sells — it is mixed and applied on site.

Typical service life: 50–100 years
The study's entry for stucco is a 50-to-100-year range, from a February 2007 survey of manufacturers and trade associations. Every other cladding in that same table is listed as "lifetime" — stucco was the one the survey would not round up. Which end of the range a given wall reaches is decided by what sits behind it: drainage, flashing and a working water-resistive barrier, far more than by the plaster itself.

Stucco is happiest where it dries. In the dry Southwest it reaches the top of its range routinely, and cracks there are a maintenance item rather than a leak. In wet and freeze-thaw climates the same wall turns into a reservoir when the drainage behind it was not detailed properly, and freeze-thaw then works that water into every crack. The material barely changed between those two houses; the water did.
Why there is no warranty bar here
Traditional stucco is made at the house, not in a factory: portland cement, sand, lime and water mixed on site and applied in coats over lath. Nobody warrants the finished wall, because nobody sold anyone the finished wall. Terms do exist one layer down — the cement and the acrylic finish coats carry their own material warranties, and proprietary one-coat and synthetic systems are warranted only where a certified applicator installs the entire assembly — but on an ordinary three-coat stucco wall the only meaningful promise is the plasterer's workmanship guarantee.
What shortens it
- Missing or reversed flashing at windows, doors, roof-to-wall junctions, and the base of the wall
- No weep screed, or a weep screed later buried by regrading, a patio pour, or new paving
- Hairline cracking left open, which turns every joint and corner into a funnel during wind-driven rain
- Sprinklers hitting the wall, and roof runoff sheeting down the same face in every storm
- Sealers and elastomeric coatings applied over a wall that needs to dry outward
Signs of wear to look for
- Cracks following framing lines, window corners and control joints — particularly ones wide enough to take a card
- Staining, streaking, or a damp patch that keeps returning below a window, a light fixture or a roof junction
- A hollow sound when the wall is tapped, where the plaster has let go of the lath behind it
- Crumbling, soft or blistered stucco at the base of the wall and around penetrations
- Efflorescence and rust-colored bleed marks tracking out from inside the wall
Cracks that follow the framing, damp patches that keep coming back, and hollow-sounding areas are all asking about the sheathing and framing behind the plaster and whether the wall is draining — that is an inspection question, not a web-page question.
