I paid 500.00 for install in NJ.
That seems pretty cheap! Was that a insulated stainless liner? Also does that include full installation of your insert too?

A lot of installers shy away from a block off plate because it is going to raise the bid and it's more work. Shoving up ceramic insulation around the liner is better than nothing and a common practice. But this rarely blocks off heat loss as well as a true block off plate.
The height of this chimney may also be part of what is in the bill but not spelled out. I saw 20 ft liner and thought it to be closer to the ground. With a steep pitch roof they may need to stage a work platform up top.
Hard to say what is common practice. It's up to the company. Some only provide a final price with little breakdown. Your estimate was fairly detailed. It's getting to be installers busiest time of the year. Best pricing is usually during slack periods.
We are scheduling the end of November now. Even in out slow time it is 2 weeks or more to give an estimate. And more than 4 weeks wait.It's even taking about a week or more just to have people come by for estimates. If I choose a company this week at minimum I'm looking at 4 weeks out for the work to completed.
