Dave, you said it best! Every pro painting contractor truly worth their salt would and should cut and paste exactly what you say here about where customary and legitimate practices and expectations should be in regards to what customers should expect from contractors and how contractors should professionally deal with their customers. By the way, Dave, if you work in the Atlanta area, I would like to hire you! Thank you for your valuable advice!
Also, don't be afraid to ask if the painters are trustworthy people. Unfortunately, there are plenty of cases where a painter has stolen items from a home or caused damage to the house or injury to the homeowner. Subcontractors may not be as skilled as employees, and the contractor you're hiring may not have much experience working with them, making them more of a risk. Additionally, ask if the painters are employees or subcontractors, and what the screening or hiring process is like. If the company conducts background checks, that's a good sign. 
After painting the ceiling, work from the top down: Start with the crown molding, then do the walls and then paint the casement molding around the windows and doors. Do baseboard molding last. "Painting the baseboards last keeps dust and grit from traveling off the floor, onto the brush and then up onto the freshly painted casements," explains Weeks.
"I had called the last minute for an interior painter, because I had flown into town for just 5 days, to get my home painted. PPP Paint Services made time for me. Made an appointment on a Monday and they were there by Thursday and done by Friday. 9 rooms including trim work. The job came out great, and at a great value. I would highly recommend this company."
The companies with the best paint products are Benjamin Moore, Dunn Edwards, Sherwin Williams, and Vista Paint. As a painter I don't recommend Berh from Home Depot as much because it's quality is just marketing. Flat paint has no sheen and it shows its true color, but is not easy to wash or clean. Satin, eggshell have low sheen and is washable. Semigloss ang glossy has a high sheen and these paints are recommended for bathrooms and kitchen or where there's high humidity and steam.
Over time, even the best paint job needs a new coat. Old paint peels and fades and those colors that were all the rage ten years ago can start to look a bit dated. With your busy schedule, you've got no time to pick up a paintbrush, and you've just remembered that your in-laws are in town for dinner next week! We hear stories like this all the time, and our reply is always the same: don't panic! Book a painting professional through the Handy platform. Wall painting shouldn’t be stressful and when you use the Handy platform, it won’t be.
I used to work at Sherwin Williams. The best thing to do is specify that you will purchase your own paint. If the painter objects strenuously, he was plaanning on making money in the ways this article outlines. You might pay a few dollars more for paint, but you will have control of the quality of what goes on your walls. Never skimp on paint quality.
to be the devils advocate i have been a building contractor 20 of the last 30 yrs. i do know that if you go to a higher sheen of paint and or darker colors then any imperfections in the walls will show up much more dramatically…therefore the painter or a good drywall finisher is needed to prepare the walls extensively. this could cause more expenses…for it takes a lot of time to prep walls (smooth walls..not textured walls) and this cost has to be absorbed.
