Requested estimate for Flue valve and Chimney cap repair/install.
Ended up need a new liner and some cement work as well.
Mike was professional, and described the issues (and provided pictures) of what need to be replaced and why it needed to be replaced. The flue didn't need to be repaired as it was just off track, and Mike was able to put it back on the cog wheels.
Overall, Mike and his colleague were quick and courteous.
Only reason why I am not giving 5 stars, is that the work space in the basement by my furnace was not cleaned up after their cementing work. There were chunks of old concrete and concrete dust on the floor (this was not there before they performed their work).
There was also some small pieces of trash left on my yard (pieces of a cement bag, aluminium trimmings, and what appeared to be plastic adhesive tape).
