Nothing is more frustrating that not being on the same page as your professional. During your in-home meeting, clarify your expectations of the job and have the painter set appropriate expectations on his or her end as well. If you want the painter to show up at an exact time every day, or if you need them to leave at a certain time, see how your schedule might impact the completion time. Additionally, ask the painter about their expectations for the job like requiring a staging area for supplies, needing to use the driveway, or having access to running water. Don't forget to ask about the clean up and disposal expectations and find out if they need access to your garbage receptacle or if they plan on leaving extra paint with you.
It's okay to receive ballpark figures over the phone however, insist upon an in-home estimate. A quality painter will help point out why certain parts of the project might be more expensive and can even talk through the repair process if it's necessary. A painter should also ask questions regarding access to the painting site, where they should park and if any HOA rules prohibit hours of work. House Painting
