I know I've been a bit of a pest laetly with questions, but I've got one more. I got a quote to install a pellet stove vent last night for $1300. It is a bit of a different install - up 25' through a cathedral ceiling with a jog off to the side in between the celing and roof, an then out the top. It is 4" venting. Is this a fair price? I had priced out the parts myself to install it and it actually seemed to come pretty close to this figure. Does this seems reasonable? Thanks again.
