These days, it seems like anyone with a paintbrush and a business card can call themselves a painting contractor. Homeowners who are most likely to be taken in by these unscrupulous “painters” are those who are focused on cost and cost alone. With painting, like anything else in life, you typically get what you pay for. If the painting contractor you are considering cannot answer these ten questions, proceed at your own risk. If they answer all ten satisfactorily, then you know you’ve found a great great professional contractor to work with.
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.
To maintain a wet edge, start near a corner and run the roller up and down the full height of the wall, moving over slightly with each stroke. Move backward where necessary to even out thick spots or runs. Don’t let the roller become nearly dry; reload it often so that it’s always at least half loaded. Keep the open side of the roller frame facing the area that’s already painted. That puts less pressure on the open side of the roller, so you’re less likely to leave paint ridges when doing DIY wall painting.
To win work, contractors generally have to bid against other suppliers. To make an accurate bid, they estimate the time and materials required to complete the job. They measure the area to be painted and discuss the type of finish the customer requires. They assess the quality of the surfaces to work out how much remedial work they must carry out before painting. They might have to remove old paint or wall coverings, or repair cracks and other damage. They also calculate the cost of any essential equipment, such as scaffolding for exterior walls.
