My wife and I have just purchased a Victorian home built in 1885. My insurance company said I need to fix the chimney as the mortor around it is in very bad shape. I have contacted several companys for bids. The chimney is very high above the roof line I have been told that this is from when it was built there was a wood burning stove or fireplace. There is no longer a fireplace but the gas furnace and gas hotwater heater both vent into the chimney stack. I was told that a stainless steel or aluminum liner could be put in and also the chimney could be rebuilt from the roof line but not as high. Which of course would be less expensive but I would like to keep the same look as the original chimney. Any suggestions about the liner?
