Prep. For new work the painter accepts the finish done by the drywall or plaster and once he accepts the work and starts painting he owns any wall repairs. Existing work is a different thing. I take a high intensity light and circle the kinds of defects with chalk so we are all in agreement before they start. Sometimes this results in a higher price and we have to compromise on how much to do...
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.
The obvious trick here is for unaffiliated contractors to use the BBB, PDCA, Chamber or other organizations’ logos without being a member. Other tricks include claiming membership when that membership has expired or even make up fake organizations that sound good.

Nearly every organization has a web page these days; if you suspect something, do a little searching to find out the truth.

Good contracts include descriptions of prep work and repairs; paint specs by brand name, type, color and product number; the number of coats; and a full description of the work, including frequently omitted items such as cabinet interiors and shutters. Minimize delays by specifying that, weather permitting, work will be continuous. Get a payment schedule that minimizes the down payment — the more payment you can withhold until the end, the more leverage you'll have to get the job done well and per your specifications. Insist that contractors provide proof that they carry both general liability and workers' compensation coverage.
