Not all people live where they can hire a painting contractor, like you describe. People who live in small towns can only hire painters who have a very small business, and do two or three paint jobs per week. In this case, you do have to be very careful, when you hire a painter, as we have several, in our area, who are out to make a fast buck anyway they can.
House Painter Company
When the homeowner is at the point of hiring a painter, they generally will have colors selected or at the very least a color in mind. I always ask for the colors before I bid a job. Dark colors, high sheen colors and specialty finishes require more labor, this drives price. If its not a color change or I'm going over a similar color I give the pricing option of one or two coats. The best advise I can give based on 25 years in the business is to put it all in writing,colors, brands of paint preferred, when the work can be done, who moves furniture and how payment will be handled. I never get up front money. BTW you most definitely get what you pay for with paint. Higher quality products results in and better looking job. Don't be a cheapskate when it comes to paint or the painting contractor.
