    Default Repairing a Chimney

    In our two story house, we have an oil floor furnace vented into a ~30ft tall, inside wall, brick chimney with a terra cotta flue liner; due to a structural problem which has since been repaired, the bottom ~20ft of the liner has cracked. Because another building is in close proximity, building code would require an outside chimney to also be at least 30ft tall. If we wanted to repair (not-rebuild) the original chimney, which system would be best -- cast-in-place ceramic, SS flex/solid single/double wall pipe, or something else?

    I would say the cast in place, light weight concrete would probably be the best for a couple of reasons. One it is virtually a permanent solution and two it will reinforce the structure. IMHO

    Tough call without seeing things firsthand.

    Jack's right if the brick portion is compromised.

    If not, a SS liner would do the deed. Quality flex or single wall should suffice if it's only venting an oil-furnace and no wood burning is involved.

    The bricks are fine; and we have no plans to use wood anytime in the near future. We found someone that can do a 316t SS flex liner w/ insulation that has a lifetime warranty.

    Thanks,
