The company kept in touch the whole time to make sure I was ok if they came earlier than originally scheduled. The profile of the service person was sent to me, which was really nice. He explained all the options and really gave good advice. The work was done beautifully and everything works great. When the work was being started, they put drop cloths everywhere and there was not a drop of dust or debris anywhere when they left. I would use them again in a heartbeat and plan to use them for all my upcoming projects.
