You're ready to hire a painter. You've got a few names, maybe a referral or two, and you've pulled up some Google results. Now what? San Diego has hundreds of painting contractors — from licensed, insured professionals with decades of local work to operators who'll underbid, underdeliver, and disappear when something goes wrong.
The difference usually reveals itself in the conversation before you sign. Here are 7 questions that separate legitimate contractors from the rest — and the answers you should expect to hear.
The 7 Questions
"Can you provide your C-33 license number so I can verify it?"
California law requires painting contractors to hold a C-33 Painting and Decorating license issued by the Contractors State License Board (CSLB). This isn't optional — it's the law. Unlicensed contractors can't legally perform work over $500 in California.
Any licensed contractor will give you their license number without hesitation. Verify it yourself at cslb.ca.gov — you'll see if the license is active, whether any complaints have been filed, and whether the business name matches. Takes 60 seconds and is the single highest-value check you can do.
🚩 Red flag: Hesitation, vague answers, or "I can get that to you later.""Can I see your current certificates of general liability and workers' comp?"
Two types of insurance matter here. General liability covers damage to your property during the job. Workers' compensation covers their crew if someone is injured on your property — and if they don't have it, that liability can fall on you.
Ask for actual certificates — not verbal confirmation, not "we're covered." Certificates show the policy number, coverage amount, and expiration date. Any contractor who claims workers' comp doesn't apply because they "only use subcontractors" deserves serious skepticism; that's a common evasion tactic.
🚩 Red flag: Can't produce certificates, or only has one of the two."How long have you been painting in San Diego specifically?"
San Diego's coastal climate is genuinely different from inland California. Salt air, UV intensity, the marine layer's humidity cycles — these all affect which products hold up and which fail. A contractor who has worked extensively in La Jolla, Pacific Beach, and Coronado knows this firsthand. One who just relocated from the Central Valley may not.
You're not just buying paint application — you're buying local knowledge. Ask them to name neighborhoods they've worked in recently and, if possible, to show reference photos from homes near yours. Specific answers signal real experience. Vague answers don't.
🚩 Red flag: "We work everywhere" with no specific local examples."What paint products will you use, and why?"
Paint quality varies enormously. A contractor using a premium product like Sherwin-Williams Emerald, Duration, or Benjamin Moore Aura will deliver a different lifespan than one using a bargain store-brand. On San Diego exteriors especially, this matters — salt air and UV exposure accelerate paint failure on lower-grade coatings.
The right answer isn't necessarily the most expensive product — it's a product that's appropriate for your substrate (stucco, wood, composite) and your home's sun and salt exposure. A contractor who recommends a specific product with an explanation is demonstrating expertise. One who says "whatever you want" without guidance is not.
🚩 Red flag: Vague about brands, or says "depends on what you want to spend" without further education."What does your prep process look like?"
Paint is only as good as the prep underneath it. Most paint failures — peeling, blistering, poor adhesion — aren't product failures. They're prep failures. A serious contractor will describe specific steps: pressure washing, sanding deteriorated surfaces, filling cracks, caulking gaps, priming bare wood or repaired areas.
For exterior work in San Diego, ask specifically about how they handle stucco cracks, wood rot, and corroded fasteners. For interior work, ask how they protect floors, furniture, and hardware. The detail in their answer tells you whether prep is an afterthought or a core part of their process.
🚩 Red flag: "We clean it up and paint it" — no mention of specific prep steps."What does your warranty cover, and for how long?"
A reputable contractor stands behind their work. A workmanship warranty of at least 2 years — covering peeling, blistering, and adhesion failures caused by application — is standard for quality contractors. The paint manufacturer separately warrants the product itself.
Dig into the terms: Does the warranty cover the full project or just certain surfaces? Is there a process for submitting warranty claims? Will they come back and repaint, or just touch up? Vague warranty language usually means the contractor doesn't expect to be held to it.
🚩 Red flag: No written warranty, or "just call us if anything happens.""Will I receive a written, itemized estimate — and what's the payment schedule?"
The estimate should specify: surfaces included, paint products and sheens, number of coats, prep scope, timeline, and total cost. Not a ballpark. Not "around $X." A line-by-line written document you can compare against other bids.
Payment terms should also be explicit. A reasonable structure for larger projects: a modest deposit upfront (10-25%), progress payments tied to milestones, and the balance due at final walkthrough — not before. Contractors who want 50%+ upfront before work starts are a risk. Learn more about what to expect during a professional painting job.
🚩 Red flag: Verbal estimates only, or requests for more than 50% payment before work begins.How Paint Works Pro Answers These Questions
