When the homeowner is at the point of hiring a painter, they generally will have colors selected or at the very least a color in mind. I always ask for the colors before I bid a job. Dark colors, high sheen colors and specialty finishes require more labor, this drives price. If its not a color change or I'm going over a similar color I give the pricing option of one or two coats. The best advise I can give based on 25 years in the business is to put it all in writing,colors, brands of paint preferred, when the work can be done, who moves furniture and how payment will be handled. I never get up front money. BTW you most definitely get what you pay for with paint. Higher quality products results in and better looking job. Don't be a cheapskate when it comes to paint or the painting contractor. http://youtube.com/watch?feature=youtube_gdata&v=b6_WEt9k_Hw
I'm an architect and my firm routinely specifies interior finishes for projects so I thought I'd contribute a professional's perspective on the issue of how many coats of paint are deemed "acceptable". The fact of the matter is the average consumer usually isn't a paint expert and can't be expected to know about all the factors that impact coverage. That knowledge is considered "means and methods" and in a court of law, the responsibility lies with the painter or general contractor, not the consumer. What the consumer should be concerned about is the final result-does it look good and is it what you expected? The simplest way to communicate this to your painter is to stipule in your written agreement that the number of coats will be "as required to cover". That way all the guess work about what kind of primer, how many coats, how color affects the scope of work, etc., is removed from the consumer's responsibility and resides where it belongs-with the professional. In the contract that's why retention is always a good idea-typically 10% is withheld from payment until the job is completed to the satisfaction of the customer. Of course in return you as the customer have to be reasonable about what constitutes a completed job. Just my $.02.
Refresh the interior of your home: If you’re feeling like the interior of your house could use a change, try painting a few of the rooms a new color. Over time, paint can start to wear and become faded. Brighten up the rooms in your home by painting them a new color, or even just doing a new coat of the same color. You’ll be amazed at how refreshed the space looks. https://www.youtube.com/watch?v=b6_WEt9k_Hw&feature=youtube_gdata
It is often necessary to have a rental property painted -- whether it's to make it your own before you move in or to clean it up for someone new when you move out. Some buildings and landlords have pre-selected painters, while others will contract companies to paint on an as-needed basis. If your landlord or building doesn't have a pre-selected painter, see if you may be allowed to paint the walls yourself. If you're moving in and selecting a non-neutral color, understand that your landlord may require you to repaint the walls the original color when you move out -- and ensure that you're ready to make that investment down the road.
^{This is another reason why you should always hire contractors who have employees and not those who use subcontractors. If the company you hire uses only subs to paint, they have no control over the training those subs receive. However, even if you choose a contractor with employees, this does not guarantee that those employees receive training. The sad fact is that training just isn’t in the budget for most contractors.}
This guy Joe told me he was an expert at refinishing wood doors so I hired him but he wanted to paint the whole house to make it worth it. He then sent two Hispanics. Only one of whom spoke English . They painted the house left a huge mess then painted my mahogany doors with primer. The next day they painted them brown thus ruining about 5000 dollars in doors .I was at work in the four hours it took them to ruin my doors. Never leave anyone alone without watching. That was my mistake. The owner Joe refused to fix them and was such a crazed person shaking and starting to cry so I paid him 4000 dollars to go away. A week later that ugly brown paint bubbled up. Again I texted him the pictures and asked him to fix them. He refused . I plan on taking them to small claims court. He is not what he says he is. He actually didn't touch my house he has no idea how to refinish wood doors. Please come by and see my awful paint job at 615 SE 26th Ave. Ft. Lauderdale ,Fl 33301 Observe closely the brown paint over white primer showing through. So embarrassing. https://m.youtube.com/embed/b6_WEt9k_Hw

When calculating total cost of your project, one of the most important factors to consider is the paint itself.
