Quite frankly, I should have trusted my insincts by the way this business insipidly answered the phone. This chimney sweep tried for about literally 3 minutes to do the job and gave up. They threw things from the roof onto my garden and broke several of my plants. They then demanded $100 for their "effort". I later did the "impossible" job by myself. Mr Clean Sweep certainly made a "clean sweep" of my $100.
