Not only would I never let these people do work for me,I would never let them in my house! I called for a quote, the old man showed up on time, went up my attic stairs and took his FIRST step and went through the ceiling.
There was no insulation and the drywall was clearly visible. He never mentioned it. When I asked what he was going to do, he said his crew would be out that afternoon to fix the ceiling.
Never hear from them again. I have called a few time to no avail.
A real rip off company.
