How do painting estimates work, and why do quotes vary so much?

Short answer

Painters estimate by measuring surfaces and judging prep, height, access, number of coats and paint quality. Labor is most of the price. Quotes vary because painters include different amounts of prep and different products. Compare line by line, not just the total.

What drives the price

Prep: scraping, repairs and priming can double the labor
Height and access: second and third stories, steep lots, ladders vs lifts
Detail: trim, shutters, spindles and multiple colors
Paint grade and number of coats
Lead-safe work practices on pre-1978 homes
Season: late-season exterior work and rush jobs may cost more
