Painting is one of the easiest trades to enter and one of the hardest to do excellently — which means the range of "painters" answering your call is enormous. California gives homeowners real tools to sort them. Most people never use them. Here's the ten-minute vetting that separates professionals from pickup trucks.
Start with the license — and actually check it
In California, any painting job of $1,000 or more (labor and materials) legally requires a contractor licensed by the CSLB — for painting, that's a C-33 Painting and Decorating classification. Every legitimate contractor prints their license number on everything; ours is No. 1101009, on the bottom of this very page. Take that number to the CSLB's license lookup and confirm three things in sixty seconds: the license is active, the classification is right, and the bond is in place. A "great deal" from an unlicensed operator quietly transfers every risk of the project onto you.
Insurance is not a formality
Ask for two certificates: general liability (protects your property) and workers' compensation (protects you from becoming the employer of record when someone's on a ladder at your home). A professional outfit sends both without flinching. Hesitation on this question is your answer.
The questions that reveal craft
Licenses filter out the illegitimate; questions filter for excellence. Ask what prep the price includes, specifically — then compare against what proper prep actually involves. Ask which products and how many coats, by name. Ask who will physically be on your property and who supervises. Ask how surprises — dry rot, failing substrate — get priced when discovered. And ask for local references old enough to have weathered a couple of winters; fresh paint always looks good, year-three paint tells the truth.
Read the estimate like a contract — because it is one
Everything verbal evaporates. The estimate should name surfaces, prep steps, products, coat counts, exclusions, and schedule — the full anatomy we laid out in our estimates guide. When one bid is dramatically cheaper, the discount is hiding in one of those line items. Find it before you sign, not at year three.
