I hired the guys from H&M to work on my ceiling last fall and they just installed a front door for me last week. They got the door in nearly two weeks ahead of schedule. No matter who was here to do the work, they were always polite, always working (NO ONE goofing off), and I didn't feel the need to constantly supervise them. With a two year old running around the house, it was a definite plus to not have to feel like my presence was necessary if I wanted the job done right. The job they did on my ceiling is absolutely amazing. I wish I could post before and after pictures.
Pros: reasonable prices, good work, stay on schedule
Cons: none that I can think of
