Interior paint itself costs anywhere from $12-$50 or more a gallon, depending on the quality. Painting a 12x12-foot room, both walls and ceiling, can require $25-$100 worth of paint, plus $10-$50 for primer, brushes, rollers, drop clothes and other supplies. For a 1,500-square-foot home, supplies run $200-$300 for average paint, and $400-$600 for higher quality.
Pricing by the square foot for painting walls is typically between $1.75-$2.00 based on the floor plan, which equates to about $.55-.75/sq ft of overall wall space. So a 10x10 bedroom would typically cost between $175-$225 for the walls alone. Ceilings are generally between $.75-$1 a square foot, so another $75-$100, and trim should cost at least $1 a linear foot, but prices up to $3 a linear foot are pretty common, so trim for that 10x10 room would add between $75-$200. And doors should cost between $20-$50 per side.
"I needed to get my house painted quickly and professionally to get it ready for the market as soon as possible. Mr. Corzo responded immediately to my need for an estimate and arrived that day. He offered a fair estimate to paint the entire interior and exterior of my home. Job was completed in estimated amount of time and to my satisfaction. Walter does great work and I would recommend him without hesitation. He was on time, courteous, professional, and an excellent painter,"
