Cost of chimney stack

7 replies

Hello all,
I'm looking into rebuilding our chimney stack. The current one is crumbling and it needs to come down. It's probably less than 1m tall, very simple stack (no aesthetics) on a 1910 end of terrace house. How much do you think I should budget for it?

I will have our roofer to have a look at it and quote. But the problem is that it's a shared boundary with the neighbour (rental). I spoke to the letting agent and the owner is happy for them to instruct a contractor to quote. I will definitely have my own one to do the same to compare and feel like we are on equal footing here.

However, it'd still be nice to have some figure in mind prior to calling my roofer. Can anyone help? I'm in East Midlands.

I had one rebuilt last year, I’m in the south, and it’s a lot taller than yours, and has some fancy brickwork at the top which was redone so it continued to match next doors chimney. It seemed to need quite a lot of scaffolding as well, which is not cheap. It ended up costing £3000. And I’ve a 10 year guarantee.

It looks good, I no longer have to worry that it’s going to come down in the next storm, and they sorted out the flashing so the leak into the attic conversion is sorted. So expensive but I’m glad it’s done.

@tesseractor thanks for that! I hope the cost will be around that as well. When split two ways, it's manageable.

is nextdoor's owner (the landlord) aware of your expectation of split costs?

have you included the costs of party wall agreement into the costing? You will legally need one.

It’d be cheaper to just remove the whole thing, if you don’t need it? That’s what my neighbour and I decided to do!

Yes, they are aware and they are getting their contractors to quote as well. We can't do anything without each others approval.

I'm using our chimney, plus it'd look odd to be the only house on the street without a front chimney. If it was the other two stacks we have in the back, I'd be happy to remove.

Yes, the one at the back, which was shared with my neighbours, and not in use, we just removed completely.
