10 Questions to Ask Before Hiring a Stucco Contractor in San Diego
Hiring the wrong stucco contractor is one of the most expensive mistakes a San Diego homeowner can make — and the difference between a great contractor and a liability almost always comes down to the questions you ask before signing. These ten cover licensing, insurance, craftsmanship, pricing, and accountability. Print them, bring them to every estimate, and cross off any contractor who can't answer all ten.
1. What is your CSLB license number and classification?
In California, any plastering project over $500 requires a state license. For stucco specifically, you want a C-35 Lathing and Plastering Specialty License — not just a general B license. Ask for the number, then verify it on cslb.ca.gov in under a minute. SD Plastering Company holds CSLB #915601; verify it any time.
2. Do you carry general liability and workers' compensation insurance?
Stucco work involves scaffolding, heavy materials, and power tools. If a worker is injured on your property and the contractor has no workers' comp, you as the property owner can be held liable. Ask for a Certificate of Insurance — sent directly from the carrier, not a photocopy — and ask to be listed as additional insured.
3. Do you employ experienced crews or subcontract the work out?
Many general contractors accept stucco jobs and then sub them out to whoever is cheapest that week. The result is inconsistent quality and no accountability when something goes wrong. Look for a contractor who employs experienced crews who specialize in hand-troweled exterior finishes.
4. Can you produce an on-wall texture and color sample before we commit?
Stucco finishes — Santa Barbara smooth, Spanish lace, cat-face, dash, float — look different on your actual wall than in a brochure, and integral color shifts as it cures in your specific light. A reputable contractor trowels a sample board on your building so you can verify the exact texture and color in natural light before full application. If they won't, that's a red flag.
5. Is your estimate a firm, fixed price or time-and-materials?
Vague estimates and time-and-materials pricing are how stucco projects balloon in cost. A reputable contractor inspects the existing conditions — opening a small section of wall to check the lath and paper if needed — and gives you a firm, fixed-price written quote that itemizes prep, lath and paper, scratch and brown coats, finish coat, and cleanup. If the estimate is vague or won't be put in writing, keep looking.
6. What weather barrier and lath do you specify for my location?
Coastal homes within a few miles of the ocean need two-layer Grade D paper, rust-resistant galvanized lath, and an elastomeric acrylic topcoat to survive salt exposure. Inland homes in El Cajon or Poway face dry heat that can flash-cure fresh stucco. A contractor who understands San Diego's microclimates — and specifies the right materials for your specific location — is the difference between a finish that lasts 30 years and one that fails in 5.
7. What does your warranty cover, and for how long?
A written warranty is only as good as the company behind it. Ask how long it runs, what it covers (workmanship vs. materials vs. cracking), and whether the company has been in business long enough to honor it. A contractor who has been around since 1984 will be there in year 5 when a crack appears; one who started last year may not be.
8. Can I see recent references from homes in my neighborhood?
Coastal stucco work is different from inland work, and you want a contractor who has done jobs in your microclimate. Ask for references from recent projects near you, and drive by completed work if you can. Look at the finish in raking sunlight — it reveals trowel imperfections that shade hides.
9. Who pulls the permits, and how long will the project take?
Most stucco projects over $500 require a permit, and a reputable contractor pulls it for you and handles the inspections. Ask who is responsible, what the inspection schedule looks like, and get a written project timeline. A contractor who says permits 'aren't necessary' is asking you to assume liability for unpermitted work on your own property.
10. What's your payment schedule, and when is the final payment due?
A reasonable stucco contract takes a deposit for materials (typically 10–30%), progress payments tied to completion milestones, and a final payment due only after you've inspected and approved the finished work. Never pay the full cost upfront, and be wary of cash-only demands or a final payment due before the wall is done.
The one answer that matters most
Every one of these questions points at the same thing: does this contractor take responsibility for the work, in writing, and stand behind it after the check clears? A contractor who fumbles the license number, can't produce a Certificate of Insurance, won't trowel a sample board, or gives a vague verbal estimate is telling you exactly what the project will be like. SD Plastering Company answers all ten on every estimate — we hold CSLB #915601, carry full insurance, employ experienced crews, give firm fixed-price quotes in writing, and have been doing this across San Diego County since 1984.
Frequently Asked Questions
What license should a stucco contractor have in California?
Any plastering project over $500 requires a California Contractors State License Board license. For stucco specifically, look for a C-35 Lathing and Plastering Specialty License. A general B license is legal for some projects, but a C-35 specialist has passed the trade-specific exam. Always verify the license number at cslb.ca.gov.
Should a stucco contractor provide a Certificate of Insurance?
Yes. Ask for a Certificate of Insurance sent directly from the carrier — not a photocopy — covering both general liability and workers' compensation, and ask to be listed as additional insured. Without workers' comp, an injured worker on your property can become your liability.
How much should I pay as a deposit for stucco work?
A typical deposit is 10–30% of the project, enough to cover materials. Avoid any contractor who demands the full amount upfront, requests cash-only payment, or sets the final payment due before the finished work is inspected and approved.
