As a former professional painter, something that drives me crazy is when I see painters cut in around wall plates. First of all, the amount of time that it takes to cut in is usually much longer than the amount of time that it takes to simply remove the wall plate. Secondly it does not look nearly as clean as it does when the wall plate is removed and thirdly it can invariably leave paint on the wall plate itself which also looks sloppy. Make sure the painter takes them off and then reinstalls them. It's less time.
Most painters have no problem painting doors in place, but they recommend you lay the door on sawhorses and work horizontally. If you have a paneled door, start with the panels and work from the outside edges in toward the center. "Watch the corners — paint loves to puddle," warns Dixon. While the paint is still wet, lightly "tip off" the panel with an almost dry brush. (Tipping off is pulling the brush over the surface to level out the finish.) When painting the stiles (vertical) and rails (horizontal) just follow the grain of the wood. When the grain changes abruptly, for instance, where the rail meets the stile, don't stop your brush stroke — you'll only leave a lump of paint. Apply paint across the joint with a full stroke, and then tip off the overlapping section by pulling the brush in the direction of the grain. "Make sure the door is dry before painting the opposite side or rehanging it," says Maceyunas.
Depending on just how dirty the outside of your house is and on the house's size, there are two ways to approach this job. If you live in an average-size house, use a garden hose with a carwash brush attachment to bathe the big areas. For caked-on dirt, use a scrub brush or a sponge and a pail of warm water with a good, strong household detergent in it. Work from the top down, and rinse all areas where you scrubbed with water.
