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.
Interior house painting costs are calculated on a few key factors. Nationally, interior house painting projects range from $200 to $2,500. The wide price range indicates how much square footage, paint selection and labor can affect cost. One pro uses a laser to measure each room, subtracting the size of the doors and windows, and then bases the quote on the square footage of the actual surfaces to be painted. Painters may provide you with savings if you opt to paint your entire home rather than just having one room or an accent wall painted. For example, the average house painting cost for an 8x12 room with 8-foot ceilings is roughly $200, when contractor-grade paint is used. Painting ceilings, baseboards and frames can also affect cost. Pros may charge per linear foot to smooth and paint baseboards. In one area pros might charge 50 cents per linear foot to paint baseboards, while pros in another part of the country could charge $1.50 per linear foot for the same task. Painters may charge flat rates for painting door and window frames, with one charging $20-$25 and another $60 per door. Geography and regional costs to do business play a major role in the cost of interior painting. The same painter in a rural region has less to pay in taxes, transportation, insurance and overhead than they would in a major city like New York.
I managed commercial construction projects for many years, have built and remodeled several properties, and never once have I encountered any of these scams. The tone of this article is deeply troubling. The author seems to be saying that ALL painting contractors are inherently dishonest, and that has not been my experience. The underlying advice here is sound: get it all in writing and cover as many contingencies as possible--so pointing out potential pitfalls like coat coverage is helpful. But do that in the spirit of clear communication of expectations, not with the expectation that the person you are hiring will try to cheat you at every turn. Not every contractor takes outrageous advantage of change orders; not every contractor will sneak past necessary preparation and/or repairs. Contractors of all sorts get a bad rap as it is; reinforcing a stereotype with articles written from this point of view just seems unproductive.
