By the Room or by the Square Foot
There are two honest ways to price interior work. By the room, each room type carries a range that reflects its wall area and the time it takes to cut in: a powder room is a few hours, a primary suite is a full day. By the square foot, walls only, two coats, at standard ceiling height, the rate is $2.50 – $5.00 per square foot of floor area, so painting every wall in a two-story home of about 2,200 sq ft comes to $5,500 – $11,000 before ceilings, trim and doors. Room pricing is more accurate for a home with a mix of spaces; square-foot pricing is simpler for an empty house or a whole-floor repaint. A typical three-room job — one small bedroom, one medium bedroom and one large room — prices at $4,250 – $4,900.
