When hiring a contractor it is always best to hire one who is personally referred to you by someone you trust. Hiring through ads or phone book is hit and miss. Check with your local paints stores, they know the good guys from the bottom feeders. Go to the stores that sell the high quality paints like Benjamin Moore(nonpareil), Pittsburg, Sherwin Williams or Glidden. Don't go the the big box stores for referrals, the people there don't know squat!
Ideally, you want a variety of older and newer projects, and you especially want to check on a very recent project, such as something completed last month. When you do get the references list, don’t take the information for granted. Take a few minutes to check these references. Ask these homeowners about the experience while services were provided and also how well the job has held up over time.
A thorough scrubbing is a must before painting any exterior surface. It removes the dirt and broken-down paint residues that keep fresh coats from adhering and gets rid of mildew that grows on paint in all but the most arid climates. Most contractors clean with pressure washers, but in the hands of someone unfamiliar with the equipment, these can gouge wood, shatter glass, and drive water behind siding and trim. Using a hose, a pump sprayer, and a scrub brush is slower but safer, and just as effective.
to be the devils advocate i have been a building contractor 20 of the last 30 yrs. i do know that if you go to a higher sheen of paint and or darker colors then any imperfections in the walls will show up much more dramatically…therefore the painter or a good drywall finisher is needed to prepare the walls extensively. this could cause more expenses…for it takes a lot of time to prep walls (smooth walls..not textured walls) and this cost has to be absorbed.
