Novi Insulation was the worst contractor I ever dealt within my life. Their crew damaged my driveway by backing up their utility trucks over a can of polyurethane foam which left gross tire tracks embedded into seven slabs of my my concrete driveway. I had to take them to small claims court just to recoup the $1700 worth of damage. I would not recommend them they were very difficult to work with and relay on the heavy use of immigrant labor who can barely speak English.
