Stucco Patching Services
Hairline cracks, utility cutouts, impact damage — our patching crew fixes localized problems without re-stuccoing entire walls. Two types of patches, one clear recommendation after a free on-site inspection.
Cosmetic vs. Structural
Two Types of Stucco Patches — and Why It Matters.
Not all patches are the same. The right repair depends on how deep the damage goes. If the underlying lath and base coats are healthy, a cosmetic patch is all you need. If the damage has broken through to the substrate — or the old wire lath has rusted through — you need a full-depth patch with new lath. Picking the wrong one is how most patch jobs fail within a year.
Cosmetic Stucco Patch
A skim repair of the finish coat — no cutting into the wall, no new lath. We clean and key the surface, fill the damage with matched stucco material, and float the texture back in so the repair blends with the surrounding wall. All cosmetic patching complies with the exterior plaster finish coating guidelines of ASTM C926.
Right for:
- ●Hairline cracks in the finish coat
- ●Small surface chips and dings
- ●Chalky, weathered spots from sun exposure
- ●Settlement cracks around windows & doors
What's underneath stays:
The existing lath and base stucco stay untouched — we only rework the top (finish) layer. Fastest turnaround, lowest cost, and blends with the surrounding wall when the substrate is healthy.
Stucco Patch with Lath
A full one-coat system rebuild of the damaged area. We cut back to healthy stucco, strip out the old rusted wire lath, install new galvanized lath tied into the framing and building paper, then apply a fiber-reinforced one-coat stucco system to rebuild the wall in a single monolithic layer. Full-depth repairs adhere strictly to ASTM C1063 for lath fastening and California Building Code (CBC) Chapter 25 for exterior plaster systems, ensuring a water-tight barrier.
Right for:
- ●Holes where you can see the framing or paper
- ●Impact damage that broke through the stucco
- ●Utility cutouts — electrical panels, hose bibs, vents
- ●Areas where the old wire lath has rusted through
- ●Sections removed during plumbing or re-piping
What gets replaced:
Everything — wire lath, paper moisture barrier (if damaged), and a new fiber-reinforced one-coat stucco layer applied straight over the new lath. More labor than a cosmetic patch, but structurally sound and the only real fix when the substrate is compromised.

Smooth Stucco — No Patches
Smooth finish stucco cannot be patched — localized repairs will always be visible because there's no texture to hide the seam. For smooth stucco, we re-stucco the entire wall plane for a uniform finish.
Learn about smooth stucco services →When to Patch vs. Full Repair
Patching is right when:
- ✓ Single crack or hole (under 2 sqft)
- ✓ Utility cutout (electrical panel, hose bib)
- ✓ Isolated impact damage
- ✓ Settlement crack around windows/doors
Full repair is better when:
- → Multiple damaged areas across a wall
- → Water damage behind the stucco
- → Widespread cracking pattern
- → Delamination or bubbling

Common Questions
Stucco Patching FAQs
What are the building code standards for stucco patching?+
Under California Building Code (CBC) Chapter 25, stucco repairs must maintain the water-resistive barrier and framing protection. We adhere strictly to ASTM C926 standards for Portland cement-based plaster application (scratch, brown, and finish coats) and ASTM C1063 for mechanical lathing and installation, ensuring full compliance and structural integrity.
Can you perfectly match the texture of my existing stucco?+
Yes. Our patching crews are highly trained plastering craftsmen specialized in texture matching. Whether your home has a Santa Barbara smooth finish, cat face, heavy lace, dash, or sand finish, we match the existing sand aggregates and technique to blend the patch into the surrounding wall plane.
Do you fix dry rot or framing damage discovered during a patch repair?+
Absolutely. If we expose the substrate during a full-depth patch and discover dry rot, wood-decay fungi, or termite damage in the sheathing or framing, we stop and show you the photographs immediately. We provide a separate, fixed-price quote to repair the wood framing to structural building standards before closing the wall back up.
How long does a stucco patch take to dry and cure?+
In accordance with ASTM C926, cement base coats (scratch and brown) require proper damp-curing (moist curing) to reach structural strength and prevent shrinkage cracks. A full-depth patch typically requires a 48-hour cure time for cementitious base coats before the final color-matched acrylic or cement finish coat can be applied.
What thickness should the lath and stucco be for a patch?+
For standard three-coat stucco systems over wood framing, the total thickness must be a minimum of 7/8 inch according to CBC Chapter 25. We use standard 2.5 lb/sq yd self-furring galvanized metal lath meeting ASTM C1063 specifications, providing the proper mechanical bond for the new plaster coats.
