Deciding which paint to use has gotten much easier now that acrylic latexes have pushed oil-based paints almost to extinction. The acrylics offer superior performance (they don't harden with age, the way oils do, so they move and breathe without blistering), they don't mildew as readily, and they emit fewer VOCs, so they comply with new air-quality regulations. They also work over both oil- and water-based primers.
basic formula? single color exterior labor only ranges from $0.85 to $0.95 per sq foot as a BASE starting point. Prices go up depending on multiple colors, slope of surrounding areas, multiple stories..etc.Some painters charge per window to mask off. Ive seen $25 a window to $50. Interiors without flooring can be factored the same way. When you start having to do multiple colors, cut ins, masking, room isolation...etc. the price jumps considerably. I always start with a base of $0.85 a sq foot and figure it out from there. the season plays a major role too. paint and materials are charged separatly and are typically marked up at a minimum of 15%. I always tell clients this. that way they pick the paint out they want and what quality they want as well. Anyways...thats your base. 1250 sq foot home @ .0.95 a ft = $1,187.50 (one color). Pressure washing, Add another $45-$55 per hour. a 1250 sq ft home is not going to take longer than 2-3 hours if its a single story.
