Chimney Liner: Should I Rush this?

[mnowaczyk]

I schedule to have a tree company bring a 75 foot crane to take down a ~90 year old Ginko that’s attacking my house. This is scheduled for December 1, less than 3 weeks away. And my chimney is pretty inaccessible up top. Here are a few shots. The natrual gas boiler is on the left with a liner for that purpose. The square cap is a spring loaded open fireplace with just a 13” square clay liner for the open fireplace. Open fires are nice, but I think it might be nicer to squeeze in a wood stove or at least a fireplace insert. I also would really like to put a wood stove in the basement where the current natural gas boiler is hooked up. I have a new high efficiency combo boiler+water heater I hope to install soon, freeing up the front chimney. So I wonder if I should rush to buy two chimney liners and get them dropped in while the crane will be here taking the tree down.

I am not the type of guy to pay someone $3000-5000 to install a chimney liners, more like the type of guy that would buy one and drop it in myself, even if it means strapping myself to a rope up on a ladder and paying a daring friend to do the same. I am not really ready for this. So MAYBE I could delay taking the tree down. But would really like to do it this year.
