Bay Area Siding & Stucco Contractor. the rain-screen that actually sheds rain.

Bay Area siding has to deal with horizontal rain. Stucco that worked in Phoenix fails here without a proper rain-screen and kickout flashings. We re-skin Bay Area exteriors with three-coat stucco, fiber-cement lap, and natural wood — always over a properly detailed WRB with rain-screen drainage plane and weep at the slab.

About Siding & Stucco in Bay Area

Most Bay Area siding work comes from leak forensics: where the water entered, what framing it rotted, and what assembly replaces it.

Bay Area permit notes · Siding & Stucco

What we resolve before drawings begin.

  • 01

    Rain-screen + WRB

    Two-layer Grade D paper or housewrap with rain-screen drainage plane, flashed at every penetration. The Bay's wind-driven rain requires this — single-layer stucco fails here.

  • 02

    Kickout flashing + sill pans

    Bay Area's most common stucco failure point. Kickouts at every roof / wall intersection, sill pans under every window.

  • 03

    Title 24 envelope on >50% re-skin

    Full re-skins trigger envelope upgrades (insulation, infiltration). We scope these into the contract.

Siding intel · fiber cement, stucco, and the rest · Bay Area spec

Three brands run American fiber-cement: James Hardie, LP SmartSide, Allura. The right one depends on whether you prize fire resistance, install speed, or grain detail.

  • James Hardie holds roughly 90% of the US fiber-cement market; LP SmartSide is the only engineered-wood challenger with comparable scale.
  • California Building Code requires non-combustible siding in WUI zones — fiber cement and stucco qualify, vinyl does not.

The manufacturers we actually specify.

  • James Hardie

    premium

    Chicago, IL · founded 1888

    Fiber-cement: HardiePlank, HardiePanel, HardieShingle, Artisan

    ColorPlus pre-finished baked-on paint comes with a 15-year finish warranty — no scaffolded re-paints. Statement Collection comes pre-cut to LA's typical climate engineering.

    30-year non-prorated substrate warranty · Class A fire rating · ColorPlus 15-yr finish

    Watch outField-painted Hardie voids the finish warranty — always specify ColorPlus from the factory.

  • LP SmartSide

    workhorse

    Nashville, TN

    Engineered-wood lap & panel with SmartGuard zinc-borate treatment

    Lighter than fiber cement (faster install = lower labor), accepts nails closer to the edge, deeper grain pattern reads more like real cedar. Strong choice on second-story remodels where weight matters.

    50-year prorated substrate warranty · 5-yr labor

    Watch outNot a fiber-cement equivalent — engineered wood. Avoid in heavy wildfire WUI zones.

  • Allura (Plycem USA)

    value

    Houston, TX

    Fiber-cement lap and shingle alternative to Hardie

    Often available with shorter lead times and 20–30% lower material cost; spec is comparable to Hardie HardiePlank.

    50-year limited warranty

  • Nichiha

    specialty

    Japan

    Architectural fiber-cement panels (VintageWood, ArchitecturalBlock)

    Rainscreen clip system + finished cement panels give a true modern architectural look without EIFS risk. Used on modern ADUs and additions.

  • Parex / Omega / La Habra

    workhorse

    California stucco systems

    Three-coat traditional stucco + one-coat systems

    Real lime-cement stucco over felt + lath remains the most LA-appropriate cladding — fire-resistant, repairable, indistinguishable from 1920s originals when done right.

MaterialLifespanInstalled in CABest forTrade-offs
Fiber-cement lap (HardiePlank ColorPlus)30–50 years$11–$16 / sq ftMost CA single-family re-clads.Heavy; requires 2-person carry. Cut dust is silica — wet-cut only.

Specification gotchas we resolve before contract.

  1. 01

    Weather-resistive barrier (WRB) is the actual waterproofing.

    We pull old siding to verify the WRB system: 2 layers of Grade-D paper behind stucco, or a drainage-plane house wrap behind fiber cement. Without it, the cladding is decorative.

  2. 02

    Penetration flashing kits.

    We use pre-formed block-flashing kits (Quickflash) at every hose bib, dryer vent, and electrical penetration. The #1 cause of stucco re-do is missed flashing at a 1-inch hole.

  3. 03

    Galvanic isolation at dissimilar metals.

    Aluminum window flange against zinc-coated nail head against copper drip-cap is a chemistry experiment that ends in stains. We isolate or unify metals — never mix without barrier tape.

Bay Area · Siding & Stucco FAQ

Questions Bay Area homeowners ask first.

Start a Bay Area siding or stucco brief. We'll inspect the existing envelope, leak history, and write a fixed-scope contract.

  1. What does a Bay Area stucco re-skin cost?
    Full three-coat re-skins typically $22–$38 per sq ft of wall — Bay Area material and labor cost premium vs LA.
  2. Can I switch from stucco to fiber-cement?
    Yes — many Bay re-skins move to James Hardie for fire resistance, lower maintenance, and a sharper finish profile.
  3. Repair vs full re-skin?
    We assess crazing, settlement, and moisture failure separately. Surface crazing is cosmetic; moisture failure usually means re-skin.
  4. How long does a Bay Area siding re-skin take?
    Single-family full three-coat stucco re-skin runs 5–9 weeks on site, including scaffold, two-layer paper, lath, three coats, and color cure. Fiber-cement is typically faster.
  5. Do I need a city permit for a Bay siding re-skin?
    Re-skins over 50% of an exterior wall, structural sheathing changes, and envelope insulation upgrades trigger a city permit and Title 24 envelope check. We pull what's required.
