Stacee, I agree with you completely, from adding water to latex paint to taking whites from job to job. This article makes all painters look like scam artists. You get what you pay for people! There is no denying that there are scammers out there but in my experience, most painters are under paid any ways so if you want a good paint job, you are going to pay for it. If you just want a new color on your walls real quick, and that is what you pay for then that's what you pay for people. Most painters get the crap end of the stick and are left with making an entire house look good when it took a lot more than a painter to build the house in the first place. Good painters do not get enough credit. They are not all scammers who are cutting corners!
Some contractors work on time and material others on a firm contract. I would never hire the former and am leary of the latter. A contractor may low-ball a bid to get the job planning to make a killing on change orders. If you say good morning to them, they charge you extra for that. If the contract is not very, very specific and extensively fleshed out or if they display their change order schedule prominently on top, show them the door.
