Hiring someone to paint the interior of your home may be one of the toughest decisions you'll make when it comes to home improvements. If you choose the wrong contractor, you will surely pay for it every day, as we spend so much time in our homes. Not all painters are created equal. Exterior painting is much different than interior painting, where cleanliness and proper technique is critical. Like a fine cabinet maker and a framer, talents are broad. Even though both work with wood, only the cabinet maker's work needs the eye for perfection.
