Los Angeles Siding & Stucco Contractor. the envelope that hides the leaks.

Most LA homes wear stucco — and most of that stucco was installed without a proper weather-resistive barrier, kickout flashings, or two layers of paper at penetrations. When it eventually leaks (around windows, at the slab, into the framing), the repair is a real construction project, not a patch.

About Siding & Stucco in Los Angeles

We re-skin LA exteriors with three-coat stucco, fiber-cement lap, and wood siding — always over a properly detailed WRB assembly, with kickouts, head flashings, and weep at the slab.

Los Angeles permit notes · Siding & Stucco

What we resolve before drawings begin.

  • 01

    Weather-resistive barrier as an assembly

    Two-layer Grade D paper or equivalent house wrap, lapped correctly with flashing tape at every penetration. This is the difference between a 30-year exterior and a 5-year leak.

  • 02

    Kickout flashing at roof / wall intersections

    The single most common LA stucco failure point. We install copper or stainless kickouts every time, retrofitted on remodels.

  • 03

    Title 24 + LADBS for >50% re-skin

    Full re-skins trigger Title 24 envelope upgrades (insulation, infiltration) and a LADBS permit. We scope these into the contract.

Siding intel · fiber cement, stucco, and the rest · Los Angeles 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.

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.

Los Angeles · Siding & Stucco FAQ

Questions Los Angeles homeowners ask first.

Start an LA siding or stucco brief. We'll review the existing assembly, leak history, and a fixed-scope contract.

  1. What does a Los Angeles stucco re-skin cost?
    Most LA full three-coat re-skins land $18–$32 per sq ft of wall, including paper, lath, scratch / brown / color coats, and trim detail.
  2. Do I have to use stucco?
    No — fiber-cement lap (James Hardie) and natural wood are both popular LA alternatives. Each has different fire-zone and maintenance implications.
  3. Can you fix stucco cracks vs full re-skin?
    Yes — we assess whether you're looking at surface crazing (cosmetic), settlement cracks (structural movement), or moisture failure (re-skin territory) during feasibility.
  4. How long does an LA siding or stucco re-skin take?
    Typical single-family three-coat stucco re-skin runs 4–8 weeks on site, including scaffold, paper and lath, three coats, and color cure time.
  5. Do I need a LADBS permit for siding work?
    Re-skins over 50% of an exterior wall, structural sheathing changes, and envelope insulation upgrades trigger a LADBS permit. Cosmetic patch work usually doesn't. We pull what's required.
