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. House Painting Arvada
