Work was quoted at $475 for the liner and after mumbling something about 'B-Vent', which I wasn't asking about, they estimated $175 for that part of the work.
I don't know what 'B-Vent' is, but it must be expensive. The work on the vent took under 20 minutes, and used parts that you could buy at Home Depot for $20.
The bill also took a long time to arrive. They are also difficult to get on the phone, making it too much trouble to dispute the billing, but I am definitely unhappy.
However, once the two man crew arrived, they did nice work on a chimney liner install and moving the vent pipe to meet TSSA requirements. The job took a little over two hours.
