chimney flues broke

massey265

I have problems with my chimney, with the filling falling into the stove, got it checked with a camera and have two broken flu bends around about joist height, wondering is it a major job to fix and will it be costly.

Is it on an outside wall?
What caused the damage?
Have you house insurance?

It is on a internal wall, we are presuming badly built or chimney cleaner broke it.
House is insured.

Messy job then.
What I have seen done is the chimney is cut open longitudinally from below the break to the top of the stack, leaving the odd piece in place: new flues fitted, then built back up.
Messy but effective

If you claim it will affect your premium

Can you not just replace with a flue insert bendy kind and some vermiculite for the air gap.

Not if you want a complete seal, i.e. using socket and spigot or similar

reline the flue? We got a stove in recently and the existing existing chimney was found to be damaged in a few locations. Didn't really matter in the end because we put in a liner for the stove.

That would be a option, mine is a two story, what did it cost you to do?

same. around 400-600. Cant remember exactly. was rolled into the overall cost of the stove

Well IMO it does matter.

One purpose of the liner is to reduce the flue diameter and therefore reduce the draw on the stove.

While they are mentioned in Part J, in I am of the opinion that under no circumstances can it be construed to mean that if the chimney is damaged to the extent that gases can enter the house, that a flue liner is an adequate repair.

Fair point. I ensured we got a 904 liner which is more durable than the 316 alternative. Also, it's twin walled. On top of that we have a second CO2 detector in the bedroom above the sitting room. I think we're well covered and I wouldn't be worried about it.

Just found this off a chimney damage & repair website

Why should I reline my chimney?

You may need to reline your chimney if
It has been damaged by a chimney fire or some other accident
If your chimney has settled and tipped away from the house.
If it is an older chimney which may have been built without a liner installed or the liners may have deteriorated
You need to resize the chimney for a new appliance; such as converting from oil to gas heat
You need to stop excessive creosote build-up (and risk of a chimney fire) when venting a woodstove through an existing fireplace
