15 Questions to Ask Before Hiring a Painter in San Diego (Don't Skip These)

You are about to let someone into your home for days or weeks, trusting them to protect your belongings, use quality materials, and deliver a result that holds up. That warrants a thorough vetting process. These fifteen questions cut through sales pitches and surface-level promises to reveal whether a painting contractor is genuinely qualified, organized, and accountable.

Licensing and Insurance

1. What is your California contractor's license number?

This should be answered immediately and confidently. The number should be on their business card, estimate, and any written materials. Verify it through the CSLB lookup tool after the appointment. If a contractor hesitates, deflects, or says licensing is not necessary for painting, end the conversation. California law requires it for projects over $500.

2. Do you carry workers' compensation insurance?

The answer must be yes if they have any employees. Ask for a certificate of insurance. If the contractor claims to be a sole proprietor with no employees, verify that the CSLB record shows a workers' compensation exemption on file. If they will have helpers, assistants, or subcontractors on your property, workers' comp must cover them.

3. Do you carry general liability insurance, and what is the coverage amount?

Look for $1 million to $2 million minimum. General liability covers damage to your property during the project — paint on your floor, a ladder dent in your siding, a broken light fixture. Without it, damage claims become a personal dispute between you and the contractor.

Products and Process

4. What specific paint brand and product line will you use?

Not "premium paint" or "good quality stuff." You want to hear specific names — Sherwin-Williams Emerald, Benjamin Moore Aura, Sherwin-Williams Duration. The product dictates the cost, coverage, durability, and warranty of the finished job. A contractor who cannot name the product either has not decided yet or is using whatever is cheapest at the time.

5. How many coats are included?

Two coats on walls is the professional standard. One coat is acceptable only when recoating the exact same color in good condition. Trim, doors, and cabinets should receive two coats minimum, sometimes three for a color change. Ceilings typically get one coat unless stained or changing color.

6. What is your surface preparation process?

This question reveals more about the contractor's quality standards than any other. A thorough answer includes wall cleaning or washing, patching nail holes and drywall imperfections, sanding patches smooth, caulking trim-to-wall and trim-to-ceiling joints, priming all repairs and bare surfaces, and protecting floors and furniture.

A vague answer like "we prep as needed" should prompt follow-up questions. Prep is where quality contractors separate from cheap ones.

7. Do you move furniture, and how do you protect the home?

Professional crews move furniture away from walls, cover remaining items with drop cloths, protect flooring with canvas or plastic runners, remove electrical outlet covers and switch plates, and mask windows and trim edges. Ask specifically what their protection protocol includes.

Timeline and Logistics

8. When can you start, and when will the project be complete?

Professional contractors commit to specific dates. Vague answers — "probably next month" or "a couple weeks once we start" — indicate an overbooked schedule or poor project management. The estimate should include a start date and a firm completion date.

9. How many crew members will be on-site daily?

This affects both the timeline and the level of disruption to your household. A two-person crew and a five-person crew work at very different speeds. Know what to expect.

10. What are your working hours?

Standard residential painting hours are typically 7:30 or 8:00 AM to 4:00 or 5:00 PM, Monday through Friday. Confirm this matches your schedule and your neighborhood's noise ordinances. If you need after-hours or weekend work — more common with commercial painting — discuss that upfront.

Financial and Legal

11. Is your estimate a fixed price or an approximation?

A professional estimate should be a fixed price for the defined scope. If additional work is discovered during the project — hidden damage behind wallpaper, unexpected drywall issues — the contractor should communicate the finding and provide a written change order with the additional cost before proceeding. Surprises on the final invoice should not happen.

12. What is your payment schedule?

California law limits the deposit to $1,000 or 10 percent of the contract price, whichever is less. Typical payment structures include the deposit at signing, a progress payment at the midpoint, and the final payment upon completion and your satisfaction with the work. Never pay in full before the project is complete.

13. Do you provide a written contract?

The answer must be yes. California requires a written contract for home improvement projects over $500. The contract should mirror the estimate — same scope, same products, same price, same timeline — with the addition of payment terms, warranty language, and the three-day right to cancel.

Warranty and Follow-Up

14. What does your warranty cover, and for how long?

Understand the specifics. A "three-year warranty" means different things to different contractors. Does it cover peeling? Cracking? Fading? Blistering? Is it limited to workmanship defects, or does it extend to product failure? What is the process for making a warranty claim? Get the warranty terms in writing as part of the contract.

15. What happens if I am not satisfied with the finished result?

This is the question most homeowners are too polite to ask and the one that matters most. A professional contractor's answer should describe a formal walkthrough process where you inspect the work together, identify any touch-ups or corrections needed, and the crew addresses them before the final payment is collected.

A contractor who becomes defensive or dismissive at this question is showing you how they handle problems. Pay attention.

Using This List Effectively

Ask every contractor the same questions in the same order. Take notes on their answers. Compare responses side by side. The contractor who answers all fifteen questions clearly, specifically, and without irritation is almost certainly the one who will deliver the best experience and the best result.
