Don't hesitate to ask all the questions you need to feel comfortable hiring a professional. You can also ask 3-4 professionals to make sure you have the right quote in mind. You must make sure they have a warranty or some kind of paperwork stipulating the quality of their jobs. Insurance is also a #1 priority to consider, as damage can happen in the process of painting.
Take for example, I charge 1.75 sq foot for 10x10 room with 8 foot ceilings. By my calculations this would cost $175 with floor space sq foot, but with you method, it would cost $576.00 That is outrageous. Of course I didn't subtract the windows and doors, which is another thing that makes no sense. Cutting in around those windows takes more time, then just rolling a wall.
People need to realize that if you want a licensed, insured professional painter in your home that is reputable, trustworthy & skilled, that it will cost them an average of $400.00 a day. If you want a nice paint job then it is all about prep work. There is tarping, plastic, furniture moving, caulking, spackling, sanding, priming, sealing, before you even paint. I have repainted interiors that were painted less than a year because the last contractor came in with a cheap price, did zero prep work, & painted with watered down paint. My point, A house is usually the most valuable asset a person will purchase, so why would you let just anyone with a cheap quote work on it? “The bitterness of poor quality remains long after the sweetness of low price is forgotten” – Benjamin Franklin
Some service pros are employees, franchisees, dealers or independent contractors ("Corporate SP's") of larger national or "Corporate Accounts". When this is the case, you may be matched with the Corporate Account or with one of their Corporate service professionals. The above screening process is not applicable to Corporate Accounts, as HomeAdvisor does not screen Corporate Accounts or Corporate service professionals.
"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."
