One star is way too much. They do not stand behind their work. They did not plastic off the entire area in shop and we received substantial over spray over entire concrete floor as well as the brand new white garage doors. On the scheduled day for work to be completed, company only sent out one employee. There is a variance in workmanship as well. Some daylight can been seen through the insulation as a result of faulty workmanship. Company owner Brent Vanderford and partner Dan Morrow will not respond to phone calls or letters to resolve the problem. Consequently, they also have numerous phones numbers of contact, and all the businesses that they both associated with, have numerous contact addresses and phone numbers. Additionally, all businesses they have, are residential addresses. Buyer beware.
