I was a professional painter way way back for a company. Now I am dabbling in working around the neighborhood here and there and needed to know how much I should charge. I recently painted an entire home including woodwork / doors / windows/ baseboards and the paint costs $230 ish and I did it free for my best friend . It took me 4 days to do . 7am-9pm . It turned out absolutely beautiful , and every room was a different color .
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 have the time since I work from home and work has been slow, so I volunteered to paint our kitchen..10 X 16. My hubby changed his mind midway through the painting, so I had to change color. Took 3 days. I did most of the painting and he painted and did some touch up work. We spent $126 in paint and supplies which included primer, ceiling paint, primer, three colors, semi gloss for trim and chair rail, assorted brushes, roller covers, and drop cloths. After all was said and done, it looks really good.
Painting is one of the quickest and easiest ways to give your home's interior a facelift with dramatic results. Fortunately, it doesn't have to be that difficult. Home improvement stores offer samples that you can take home. With these samples, you can try a few colors in large swaths on your wall to see the how the paint interacts with the room's natural light. Compare it against design elements like pillows or furniture to see whether it will work with your overall décor.
Whether doing it yourself or hiring someone, buy the best quality paint you can afford; it lasts longer and in some situations requires only one coat of paint instead of two. Painting a room usually involves prep work, primer and latex or alkyd paints with a range of finishes. HGTV.com gives a quick overview  as well as a list of painting dos and don'ts .
I have been painting for 7 summers as a side job with a school district. I have been asked to paint a friend's house and I don't want to over charge but it will be a lot of work. She is paying for all of the paint and supplies-----5 average sized rooms plus ceilings, ceilings in 3 additional small rooms, and all window and door frames. I need some advice!!!
"Very happy to have hired Larry to repaint a bedroom in our house. He gave an honest and upfront quote based on the work needed, and he was eager to get started. He was very communicative throughout the entire process and always arrived on time. He's got a super positive attitude and should we have another project, we'll definitely be sure to call Larry! "
"C&A was not the cheapest company, but it was the only one that offered full service (removal of waste and carpet installation), and showed some real interest. Furthermore, the sales representative was on-time, polite, and always available. The finished job looks great, the crew was on top of its work, and they left after cleaning thoroughly, which not that many companies care to do. I highly recommend them."
