We used Scott and his crew to remove 3 layers of old yucky attic insulation in our 50 year old ranch home. This stuff was gross. We had a family of roof rats that we got rid of, and who knows what else had been living up there over the years. We got three quotes. Arbor had the best price. His crew worked from 9 am until 5 pm continuously. They were very polite. I was working from home during the day, and I hardly knew they were there. They brought in a truck with a vacuum attached to it, sucked the insulation out, and then left. I was impressed with the quality of the work, the price, and Scott's personality. He is a nice guy and we would use them again.
