Picking exterior house paint colors is a lot different than picking a color for a shirt or a car. It may help to drive around to observe colors that other homeowners have combined on homes that are of similar size and design as yours. There are also online resources that provide homeowners with the ability to create virtual makeovers of their home by combining colors together through their software programs as well.
Over the past year I have had several jobs given to 2 Angie's list recommendations and 1 not from a recommendation. They all have one thing in common, lack of sufficient and correct preparation to save time, labor, and the fact that they put a person in charge that was a cut corners type of worker. The two from Angie's list sent worker/s back to try touch up problems, but once the job is not prepared correctly in the first place any extra work is like putting a band-aid on a dirty wound.
