OF the different type of customers there are at least two: cheap charley's and people who want great results. I agree the need for wall repair is critical to the end results. Most critical is for the customer to be told ahead that the walls are going to need exactly what is needed. This means the contractor must look, touch, examine the walls for defects and needed work. I've been a building manager for 40 years and seen a few paint jobs. Typically a contractor does a lot of talking about how expert he is, but the guys who walk through with note pads, iPads, examine, measure, point things out, explain and recommend are the ones I will deal with. It confirms if they know what the business. Nobody likes the workers to show up and when you talk about the job they're going to do they know nothing but they we were told to be here. Their boss who bid the job doesn't supervise - a big no no around here. Nobody likes surprises or worse, at the end of a job that's not right getting a bunch of little kid excuses. Contractors that do not like the customer to be around looking at the progress don't get the job.
Some contractors work on time and material others on a firm contract. I would never hire the former and am leary of the latter. A contractor may low-ball a bid to get the job planning to make a killing on change orders. If you say good morning to them, they charge you extra for that. If the contract is not very, very specific and extensively fleshed out or if they display their change order schedule prominently on top, show them the door.
The Lead Renovation, Repair and Painting (RRP) Rule establishes requirements for firms and individuals performing renovations, and affects contractors, property managers, and others who disturb painted surfaces.  It applies to work in houses, apartments, and child-occupied facilities (such as schools and day-care centers) built before 1978.  It includes pre-renovation education requirements as well as training, firm certification, and work practice requirements. 
The food was excellent and the service was good. My only complaint would be that they would not sea...t us until all of us were there (we had 6 in our group). They wanted us to sit at the bar, but there was no seating available at the bar. I can understand this as a general rule, especially if a restaurant is busy or crowded, but almost all of the tables were vacant when we arrived. The weather was nice, so we waited for our friends outside and it all worked out fine in the end. See More
Generally, it will take a minimum of two gallons of paint to cover a room. At the highest end, paint will cost anywhere between $30 and $60 per gallon and come in three different finishes: flat, semi-gloss or high-gloss. Flat finishes are the least shiny and are best suited for areas requiring frequent cleaning. Semi-gloss finishes are a bit shiny but can also be easily cleaned. A high-gloss finish is stain-resistant and easy to clean. Traditionally, living rooms should be painted with a flat finish to allow the paint to stand out. Glossy finishes should be reserved for hallways, and a semi-gloss is best suited for trim. Invest in pre-primed paint whenever possible. This cuts down on time by combining the layering process. Almost any paint job will require a primer, which will cost anywhere from $7 to $15 per can. Primer helps the paint to stand out against the underlayer of paint it's covering, especially if the new paint is lighter than the old coat. You will need at least two cans of primer, if not more, to cover one wall. Here are some paint brands and their average price per gallon:
