Chimney breast removal
Just after some advice. I have bought a house with intentions of removing the chimney breast and having read on various pages the needs that differing situations involve I have a few questions.
1) when asking for quotes what qualification/accreditations will I be asking if the builders have? 2) what insurance do they need to have? If there are any pointers that you recommend I do, they too will be greatly appreciated. |

That is a job that needs building regulations approval, which will almost certainly require a structural engineer's report. The structural engineer ought to know which builders in the area are capable of tackling the work satisfactorily. So, your first step is to look up structural engineers in your area. Colin Bignell |

Colin Bignell Slightly more detail needed, e.g does the stack have to come down too? Are you looking to leave it supported after removing the breast? Age and construction of property? My house had an internal chimney added to an older stone structure. Before I moved in the stack had been removed and the roof completely replaced, leaving a simple brick structure inside which was easy enough to remove. |

Chimney breast removal
If it is a chimney on a party wall, approach your neighbour
about removing the whole visible stack - assuming they don't actually use the chimney. I've seen too many shared stacks cut in half and the don't half look a mess. JGH |

I have removed several chimnys, but always the lot, from top to bottom. Apart from mess, roof /ceiling repairs and work involved, the main problem I have found is the back of the chimney may not line up with the walls on either side, So, you are left with removing that as well or chiselling away/filling in the hole in the brickwork. Really hard going that one. Another problem is that the chimney may support the roof structure and alternative support must be found. I think trying to remove the chimney breast while leaving the stack is a very bad idea regardless of the dodges one sees advocated. You do gain a lot of space. |

The structural engineer ought to know which builders in the area are capable of tackling the work satisfactorily. So, your first step is to look up structural engineers in your area. Back when mine was done (1980's), BR approval was not required providing it was being dismantled from the top, and providing it was not leaving half a stack above the roof (as you might be inclined to with a shared stack, and this is apparently because any remaining exposed stack will almost always need to be completely rebuilt). In my case, it was the neighbour who wanted to remove the full chimney breast, and they did not need BR approval providing they also removed my half of the stack above the roof, which they did. The BCO came and looked at my half in the loft before declaring it didn't need any BCO approval, so there may have been some other factors he saw that I wasn't aware of. -- Andrew Gabriel [email address is not usable -- followup in the newsgroup] |

I don't know why people fuss over removing chimney breasts - I've removed dozens of them and never had any problems. People seem to think that they are a freestanding structure that the house is built around, and by removing the bottom, the whole lot will cave-in, this has never happened and never will because they are keyed into the external wall at each side, so an inverted V shape of brickwork may fall, but that's it. Some steel gallows above the bedroom ceiling, at each side and below the mid feathers and all is sound again. |

They decided to take the fire place out and started at the bottom. They had the whole concrete lining and the outer chimney fall in. None of it was tied into the external wall and it was completely free standing. Some steel gallows above the bedroom ceiling, at each side and below the mid feathers and all is sound again. |

Understanding of gravity? Next door neighbour hired some dodgy builders that started removing bricks at the bottom. The resulting crash was his chiminey through our garage roof.... oh, how we laughed (not) -- Adrian C |

Never heard of a concrete liner in a chimney, nor have I ever seen a chimney breast in 30 years of working in old houses that wasn't keyed in to the wall it was built against. Must be a regional thing as I've only really worked in a hundred mile radius of Manchester. |

They rested on a concrete slab supported above the fire place by low walls of some kind. The whole lot ended up in the living room having demolished the wall built to hide it. It was a smiths house BTW, you don't tie anything to the walls or they fall down. |

So it wasn't a chimney breast then, it was a fake wall hiding a concrete tube which was being used as a chimney. I thought we were talking about brick built chimney breasts. |
