I had a leaking chimney liner that was flooding my basement late one evening during a heavey down pour. I called MacKay's 24 hour service number and they were very reassuring on the phone and told me what to do until morning. First thing the next day Peter was here to assess the situation and then Adam came to do the work that same day. Turns out it was not the liner that needed repair, only the cap that was badly installed allowing rain to fill the chimney with water between the bricks and the liner.....then flooding my basement. They re-installed the chimney cap and the bill was half of what it was quoted - they didn't do more than they had to, were honest about what they found, took pictures and showed me what they found, were extremely reassuring late at night when I was frantic, and super polite and professional when they arrived to the moment they left. Thanks for being there when I needed someone in a hurry!! Thanks for being honest and for taking the time to care enough to explain what you were doing each step of the way. Got more than my money's worth actually - found a great HVAC team in this new city of mine.
