I'm hiring an interior painter and that is why I was reading this comment list. I'm concerned about your comment about Angie's List. Some of us don't have personal recommendations for tradespersons, and rely on sites like this. Are you saying that Angie's List's reviews are not complete or that they do not print some of the negative reviews? It's hard to know what to do - I have not been able to find a person who just had their paint done so I can ask him/her about the quality of the painter.
Priming walls and ceilings is mandatory whenever you're painting new drywall or painting over a dark color. But it's smart to prime any time you paint. Primer serves three main functions. First, it blocks stains from bleeding through. Second, it allows one-coat coverage for the paint. Third, and most important, it improves paint adhesion, which greatly reduces blisters and peeling.
Even if you plan on painting your home in various shades of white or off white, there is still a fair amount of planning that should go into the project to ensure that you get the results you want. Color and tone have a powerful impact on how a room is perceived, so it’s crucial to take the time to view each room on its own and in conjunction with the rest of the space.

I am a painting contractor and have been since 2001. Make sure the estimate provides in writing: What is EXCLUDED as well as INCLUDED. It should state the manufacturer and type of paint going to be used. Estimate says ALL LABOR AND MATERIALS. My estimates to my customers say "guaranteed coverage" eliminates the conversations of 1 coat vs 2 coat. I have my customers submit colors 5 days prior to start date. Customers need to inform me if they are going to use pure white, dark reds, oranges, and bright yellows they need to inform me in that 5 day window, so I can adjust my pricing for 3 coats. Although this more uncommon now than years past because a lot of paint manufacturers have primer with paint products. Let the contractor know if your doing accent walls. This takes longer to cut in straight lines and it requires the contractor to purchase more paint. If you add anything on the scope of work have the painter write out the description and cost prior to them doing the work. Have the estimate say how many days it will take to perform the work. Ask how many workers will be doing the job. Make sure to enforce that number of workers their everyday until the job is complete. Do not give final payment until you do a final walk through. Walk the job when its almost complete and point out areas that you want fixed prior to the contractors final walk through. Its best to do while the workers are still in that particular area as they will have tarps down and areas covered and it will be easier for them to take care of. Purchase a roll of blue tape and stick it to areas that you want fixed. This is called a punch list.

So sad that Angie's List requires the contractor be notified!! They have lost me as a client. If I'm dissatisfied and want to give an "F" rating (question/workers...I SHOULD NOT be intimidated into passing up an opportunity to explain my experience! There is NO WAY my contractor got an Aplus rating from over five hundred people....so someone was lying....yet I can't report that without the contractor knowing it? REALLY?

I've seen this article sent out 4 times now. It's out dated in terms of today's "Scams." Paint stores haven't charged more money for deeper paint colors in over 15 years. Also Water downed paint? Seriously? That would never happen in the real world. And Wall repair? what painter would ever not assume wall repair as included? This article is a waste of time and should be taken down or edited to reflect actual scams of todays times.
Before the project began, Warren walked through the home with myself and the paint foreman and ensured we were all on the same page, the crew worked around our schedule and did an amazing job. The estimate and the final bill were exactly the same, they ensured we were 100% satisfied. Great experience and plan on having them back to finish painting the remaining rooms and the exterior of our home when the time comes. Customer and Quality are their top priorities.  
Most of the time, the reality is different. Painting  the bulkheads around cabinets is alone more time consuming than painting an entire wall. We dread having to move the appliances and paint behind them. Moving an older fridge is like opening a Pandora’s box. Sometimes the wheels are broken and the refrigerator may damage the floor. Other times, the surfaces behind the appliances are greasy or dusty. In a small kitchen, there isn’t much room and working behind the appliances is uncomfortable. For all the reasons that were mentioned, pricing a kitchen is unpredictable.  A range of $280 to $450 should cover most possibilities.

When hiring a contractor it is always best to hire one who is personally referred to you by someone you trust. Hiring through ads or phone book is hit and miss. Check with your local paints stores, they know the good guys from the bottom feeders. Go to the stores that sell the high quality paints like Benjamin Moore(nonpareil), Pittsburg, Sherwin Williams or Glidden. Don't go the the big box stores for referrals, the people there don't know squat!

Painting the doors and the door frames is not always part of the main paint job. There are two main reasons for that. Doors are painted in more durable semi-gloss or satin paint which last longer and is washable. The other reason is cost savings. Painting trim such as doors and door frames is time consuming and relatively more expensive than walls. There are three basic types of painted doors.
It’s important to note that complimentary hues work best with each other when they are of the same value. Referencing the provided color wheel, you’ll notice that each pie wedge is segmented into rings of decreasing size. And the value of each hue changes as the rings get smaller. So, if you’ve decided your kitchen needs to be a pure red (the outermost red), then it’s complimentary color is going to be a pure green (opposite & outermost on the ring).
Most painting companies, including our own, do not price our work on an hourly basis. We can work this way and do on complicated projects. But to give you a good idea of what the hourly rates tend to be, these range from $45-60 a man/hr. Then you have to factor in the cost of materials. This tends to range from 10-20% of the cost of the job depending on the level of quality.
Just like with roller paint application, painters are not limited to using just one stroke when cutting in. It is important, however, to work towards the edge of the corners applying even pressure. If time permits, painters should allow their cut in work to dry completely before applying paint with rollers, keeping in mind that light touchups on corners and edges will always be required at the end.
The cost to paint an average size room (10X12) ranges from $380-$790, not including ceilings, trim or cost of the paint. DIY, this can cost between $200-$300. When estimating the cost, painters will start with how much paint will be required to complete the job. To know this, they first need to know the size of the area to be covered. The easiest way to calculate the size of the paintable area is to add together the length of the wall and multiply it by the width of the room from floor to ceiling. The resulting amount is the room's square footage. This total is a starting point, as it is not all paintable surface. The painters won't paint the windows and doors, for example, and they must account for ceiling trim and baseboards as well. The next step is to subtract the area of the doors and windows -- along with the square footage of the trim and baseboards -- to get an average. Then, use the same calculation (length x width) on the windows, doors, trim and baseboards, and subtract all of those numbers. The result of this equation is the square footage of the room's walls. This is your surface area number. (Painters will typically add a little square footage back in to this amount to account for extra paint, which may be required.)
