Hi all,
thanks for the (partly) useful help. No the chimney isn't being used atm, that would be a very bad idea indeed. The flue has been used for years without any problems, unfortunately it took a big knock and the 4 sections came apart. Obviously 1 piece would be preferential but right now I'm looking for ways to seal it back together, my first attempt failed and I was wondering if anyone has any experience sealing it back together and could share some wisdom as to why the cement didn't work.
thanks,
R
