My first post here, thanks in advance to anyone who can lend me their professional advice.
I've bought a house with a brick chimney badly in need of repair (top 16 courses of bricks need replacement). The chimney is on the outside wall of the house (not internal). It has two wood burning fireplaces which vent through it. It turns out though that the wood burning fireplaces will not meet WETT certification anymore, so we're never going to use them. The plan is to convert one or both to gas inserts in maybe a year.
My question is, is there any reason why it would be better to rebuild the chimney and use it to vent the future Natural Gas exhaust through it? Or would it make just as much sense (or more sense) to remove the chimney down to the roof-line, or a little lower, and cap it off - then when we put in the gas inserts, go with the co-axial vent configuration straight out the side of what was the old chimney? Or does it make no difference either way?
I'll try to add a couple pictures for clarity.
I only ask because I'm thinking it's probably more expensive to rebuild the chimney than to take it down and cap it.
Thanks a lot!
