Take for example, I charge 1.75 sq foot for 10x10 room with 8 foot ceilings. By my calculations this would cost $175 with floor space sq foot, but with you method, it would cost $576.00 That is outrageous. Of course I didn't subtract the windows and doors, which is another thing that makes no sense. Cutting in around those windows takes more time, then just rolling a wall.
Specialty painting, like murals and trompe l’oeil, costs $40 to $50 per hour. Paint might range between $75 to $90. The professional’s skill and experience are also determining factors. While a freelance artist might charge $25 to $30 an hour, a very skilled professional might charge $80 or more. Some might also charge $60 or more for a consultation.
Although painting a room sounds easy, it can be difficult for inexperienced individuals to coat a room evenly. Too much paint and bubbles start to form, while using too little paint can leave sections pale and off-color. Hiring a professional interior painter near you can eliminate these problems. Plus, a pro can offer color and paint type suggestions, ensure that paint doesn't get on your furniture and floor, and may be able to offer specialty finishes and patterns.
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.
People need to realize that if you want a licensed, insured professional painter in your home that is reputable, trustworthy & skilled, that it will cost them an average of $400.00 a day. If you want a nice paint job then it is all about prep work. There is tarping, plastic, furniture moving, caulking, spackling, sanding, priming, sealing, before you even paint. I have repainted interiors that were painted less than a year because the last contractor came in with a cheap price, did zero prep work, & painted with watered down paint. My point, A house is usually the most valuable asset a person will purchase, so why would you let just anyone with a cheap quote work on it? “The bitterness of poor quality remains long after the sweetness of low price is forgotten” – Benjamin Franklin
"I had Sam and his team come in to repaint our kitchen cabinets that were originally a dark wood stain. He cleaned, sanded, primed, and put on 2 coats of sheer white on both the doors and frames of the cabinet and they came out great. The kitchen is much brighter and even up close it is hard to tell that the original cabinets were not white. They were prompt and very communicative over the phone. We may soon hire them back to paint the kitchen next."
