Paint will be your next-biggest cost, at anywhere from $20 to $70 or more per gallon, depending on the sheen, the grade you’ve chosen and any special features. Some paints, for instance, are mold resistant. Others suppress smells or require fewer coats. Some have a lifetime warranty. Paints with warranties, however, may not be worth a higher price. In Consumer Reports tests approximating nine years of wear, only a few exterior paints and stains with lifetime warranties held up well. But “you’ll grow tired of the color long before a good-quality paint wears out,” Bancroft says.
I do not mean to come off with an edge, however, this is an article for people hiring low bid, uninsured, one man band painters out to "hustle" a buck. Hire reputable, established companies or hire someone you know or have a strong referral from. If you are arguing over watered down paint, ticky, tacky deposits, buying your own supplies, you have hired the wrong guy.
A fellow (actually lives in the same neighborhood) by the name of Wayne Hickey (843-655-0366) painted the ceilings and most of the walls of our house in February 2017. He got paint all over my light fixtures, all over my trim around the doors, and had visible lap marks everywhere on the walls. He came back and rectified some of the problems, but not all, as I have noticed as I have had time to look more carefully at the work he and his assistant did. His assistant had no idea (not a clue) how to roll paint on a wall or ceiling. Some places were not covered. He said he would pull nails for pictures and then re-insert the nails exactly where they were. This he did not do as he promised. He painted over the nails. His assistant had no idea how to use a paint roller. I have painted all my life, and would have done this work myself, but I just had a full knee replacement and the other knee is in bad shape. I just could not do the work. Wayne is a pleasant and congenial individual, but he can not cut in a ceiling or wall to my satisfaction - not even close. He should have a putty knife and wet cloth with him all the time to correct any paint that might get applied where it shouldn't. That is something I always did as a painter. I would not recommend Wayne to paint anybody's home.
