Had some interior work done recently. The "professional" four man crew was fast; painted three rooms plus woodwork in one day. I am thinking they were too fast. I would have preferred slower, more precise work. Not good with detail, the rollers used left fibers on the walls, did not apply second coat on some of the walls allowing primer to show through ( in living room!), splattered paint on kitchen floor and furniture, smokers, left me a wet cellar floor, and two bags of garbage outside of house. Now that the walls are drying I am noticing a lot of spots that were missed or totaly ignored. If you need fast painting and are not detail oriented they'll do.
