The cost of ceiling painting varies nationwide, depending on factors like ceiling type, size, and paint quality. On average, homeowners can expect to pay $1 to $3 per square foot for professional ceiling painting. For a 12'x12' room, this typically comes to $150 to $350, including labor and materials. If your ceiling has special features like vaulted ceilings, textured surfaces, or requires stain-blocking primers, costs may increase to $4 to $6 per square foot. To get an exact price, request estimates from local contractors and compare quotes from at least three professionals before making your choice.
