Tipping house painters is good etiquette. You can base the tip on the size of the crew, and request the amount to be evenly divided. Or, you can leave a tip based on the size of the job and leave it up to the foreman to decide how it is distributed among the crew. Sometimes — especially with big projects — the painters on the job change during the course of the project, so it’s often customary to leave one tip for the whole job.
"Rafael was very professional, detail-oriented, pleasant to communicate with (responds promptly, returns calls, confirms appointments) and always showed up on time. He painted my daughter's room beautifully and for a reasonable price (offered pricing with and without paint). His work was precise and without mess. I will definitely hire him again for more painting projects."
