Transition from brick to metal

camiarrobino Member Posts: 49
Is it possible or common to transition from brick chimney to metal chimney just from the roof up? If so, would it require a liner the whole way down to the oil burner in the basement?

Weighing out what my options would be if I wanted to eliminate my old, leaky chimney that my oil furnace vents into. It's flashed properly, the issue is the brick is so old and porous (I do seal it every so often with a masonry sealer and this helps)

    A insulated stainless liner all the way down will protect the flue passage from blockage from loose chimney material....

    Yes it is possible. Bit of a patchwork, but possible. But if you go metal there, you need to keep on going all the way down.

    If it were mine, I'd get a good chminey mason up there (they do exist) and replace what brick needed replacing -- probably most of it, if it has been "sealed" at some point, which ruins it. But that's me.
