A gallon of paint costs $15 to $40 and covers about 350 square feet with one coat. Designer varieties can run over $100 per gallon. Your contractor pays 50 percent less than what it runs in a home improvement store. You’ll also need to spend another $20 to $100 on supplies like brushes, rollers, masking paper and plastic. A professional will have these items on-hand.
I was a professional painter way way back for a company. Now I am dabbling in working around the neighborhood here and there and needed to know how much I should charge. I recently painted an entire home including woodwork / doors / windows/ baseboards and the paint costs $230 ish and I did it free for my best friend . It took me 4 days to do . 7am-9pm . It turned out absolutely beautiful , and every room was a different color .
Interior paint itself costs anywhere from $12-$50 or more a gallon, depending on the quality. Painting a 12x12-foot room, both walls and ceiling, can require $25-$100 worth of paint, plus $10-$50 for primer, brushes, rollers, drop clothes and other supplies. For a 1,500-square-foot home, supplies run $200-$300 for average paint, and $400-$600 for higher quality.
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.
