Paint gets more expensive as you go from flat to gloss. The difference is usually around $1 per gallon per sheen upgrade. Flat is the cheapest, then matte flat or eggshell, satin, semigloss then gloss. Paint also gets much more expensive the darker it gets. A white or neutral paint color can be as much as $20 less expensive than a deep base red or blue.
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.
Look for signs of a good contractor.Product knowledge and clear communication are the signs of a good contractor. “Look for a pro who recommends high-quality paints,” says Rance. “They should prioritize finish and durability over speed of application for a long-lasting paint job.” And, notes Bunting, a good contractor will respond to you in a timely manner.
"We used Next Door Painting for the exterior and one room on the interior of our house. Scott Finkelstein and his crew did an excellent job. They were reasonably priced, very professional, helpful with ideas and accommodating to our wishes and needs. I was contacted within an hour after my Thumbtack request, made an appointment for an estimate and was impressed with the knowledge and quality of the presentation. I definitely recommend them for the job and will use them again.
If the point of hiring a well established, experienced, reputable painting contractor is to secure the professionalism and trust suggested to be inherent with that choice, then I would EXPECT that professionalism and experience to include the ability to make the proper and correct calculations for labor and materials for a fixed price quote, and there should be NO reason for the contractor to put the cost burden of their miscalculation on the consumer.
