Second: all the tricks of the trade in regard to "cheating" customers is for hustlers and cheaters and NOT established businesses. At the end of the project the job should come out looking professionally painted as specified in the contract. A selected color that takes multiple coats that was not calculated by the contractor should cost more money. It's not the fault of the painter.
As you walk through your lighted rooms (preferably day light) see if the new coat has light spots showing the precious paint. This is call "bleeding through". This means that there's only one coat of paint or the paint was diluted or the trasition of colors were from light to dark (or the other way around) and primer was not use or the painter is inexperienced.
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.
The pros were split on this tip. "Masking tape is problematic," says Mark Dixon, a painter in Missoula, Montana, and author of "House Painting Inside and Out" (Taunton Press, 1997). "Paint can bleed behind the tape, or remove the paint it's stuck to." Another problem is bridging. "Latex paints form a skin," says Dixon. "Removing painted tape can tear the skin, resulting in a ragged rather than a sharp line." Lastly, taping takes time. "Learning how to cut in with a brush takes practice, but if you can do it, you'll leave most tapers in the dust," Dixon says. (Cutting in is painting just the surface you want, not the surface adjacent to it — for example, where a wall meets the ceiling.) On the other hand, "If you can't cut in, you can't beat tape," says Span. The pros we spoke with all recommend painter's (blue) tape because it's easier to remove than masking tape. To prevent bleeding, Span uses a putty knife to bed the tape. After letting the paint dry, he scores the edge of the tape line with a utility knife to avoid tearing the paint.
O'Neil patches shallow holes and divots with Ready Patch because it dries fast, sands smooth, and stays flexible. Deep cracks and rotten spots are best repaired with two-step epoxies, such as those made by Advanced Repair Technology. (For a step-by-step instructions, see Repairing Rot with Epoxy.) The days of using polyester auto-body fillers on wood are over. "They cure too hard," says Portland, Oregon–based painting contractor Kathleen George. "They look good at first, but then they peel away."
I am in northern Nevada and you have not yet gotten sufficient responses to provide a painting cost chart showing the averages. I do have a quote from an outside (Not Homeadvisor referral) painter who is local for $2,750 for soffits, patio cover and posts, Garage facia (redwood clapboard above (~300 ? Sq. Ft.) on a 2046 Sq. Ft. home where the walls are 9 ft tall and it is fully stuccoed with plastic stucco surfaces, so not being painted.
