What are the biggest red flags when hiring a painter?

Painter red flags cluster around three patterns: deposit-and-disappear, scope creep mid-job, and quiet paint-grade substitution. The downsides are paying for premium paint and getting builder-grade, lead-paint exposure on pre-1978 homes, and warranty failure 18 months in.

Large upfront deposit, especially before paint is on site. California licensed painters cap deposits at 10% or $1,000. Anything above 20% upfront, demanded in cash, especially from a painter with no permit history, is preparing-to-disappear behavior. A real painter buys paint after the deposit and provides receipts.

"Additional surface prep needed" mid-job upsell. The painter starts the job, then announces that the surface requires more prep than estimated — extra primer, extra patching, extra sanding, "or the paint won't hold." Sometimes that's true (galvanized metal that wasn't disclosed, peeling lead paint not visible in the quote walk-through). Often it's leverage extraction — once half the house is painted, the homeowner has no negotiating power. Defense: walk the entire property with the painter during the quote, get the prep scope in writing, and require any change orders to be signed BEFORE the additional work starts.

Paint-grade substitution. The contract specs Sherwin-Williams Emerald (top tier, ~$80/gallon) but the actual paint applied is SuperPaint (~$50/gallon) or Promar 200 (~$30/gallon, contractor-grade). The homeowner pays Emerald pricing, gets contractor-grade durability, and the warranty failure shows up in 18-24 months when the paint fades or chalks. Defense: require the written contract to specify brand, line, sheen, and color, and require the painter to leave the empty cans on site. Photograph the cans before they're hauled off.

No EPA RRP certification on a pre-1978 home. Federal law requires EPA Lead Renovation, Repair, and Painting (RRP) certification for any work that disturbs painted surfaces in a pre-1978 home. A painter without RRP cannot legally scrape, sand, or remove paint in your pre-1978 home, and you (the homeowner) inherit the lead-paint liability for any tenants, children, or pets exposed. Verify RRP at epa.gov.

No written paint spec. "We'll use good paint" is not a spec. A real spec lists: manufacturer (Sherwin-Williams, Benjamin Moore, Behr), product line (Emerald, Aura, Marquee), sheen (flat / eggshell / satin / semi-gloss), primer (separate spec), number of coats per surface, and color (with manufacturer color code). Without the spec, substitution is undetectable until failure.

Padded hours. The painter estimates 5 days, the job stretches to 9 days, and the final invoice adds 4 days of labor "because of unforeseen complications." Defense: fixed-price contract with milestone payments tied to coverage area completion (e.g., 25% on bedroom complete, 50% on living areas complete), not hourly billing.

No itemized estimate. "Around $5,000 for the whole house" is not a quote. Real estimates break out labor hours, paint gallons (by brand/line/sheen), primer, masking, and prep.

Missing or wrong license. California requires a C-33 Painting and Decorating license for jobs over $500. Arizona requires C-48. Florida and Texas have no state painter license. In no-license states, the verification falls back to Secretary of State entity registration, court records, and insurance carrier verification.

Groundcheck (earthmove.io/trust) verifies the C-33 (or equivalent) license, EPA RRP status where listed, court records, and BBB complaints. It does not verify the actual paint brand applied — photograph the cans.
