On the St Helier estate and the 1930s streets around it the stacks are modest, but modest is not the same as self-supporting. Whatever sits above the breast has to land on steel. We appoint a structural engineer to size the beam and its padstones, prop the opening safely, and run the job through building control.
Removing a chimney breast in Morden's semis
Many Morden homes still carry their original chimney breasts in the ground-floor reception and the bedroom above, even where the fireplaces have long been blocked up. Because the breast helps support the masonry stacked over it, we start every job with a structural engineer establishing exactly what is being carried before a single brick is disturbed. That is what separates a safe removal from a dangerous one.
Where we take out a breast on the lower floors but retain the stack higher up, we support that stack with steel gallows brackets bolted into the party wall, or a small beam where the brickwork will not accept brackets. In many Morden semis the cleaner answer is to remove the full-height stack entirely and make good the roof, and we will advise which suits your house.
Party wall and building control in Morden
As Morden's houses are semi-detached, the chimney stack usually sits within the party wall shared with next door. That makes removal notifiable under the Party Wall Act, so you serve notice on the adjoining owner before work begins, and gallows brackets themselves fix into that shared wall. Handling the notice properly keeps relations with the neighbouring SM4 household straightforward from the outset.
The structural support is notifiable under the Building Regulations, and Merton Council's building control signs it off, not the planning department. We manage the lot: the engineer's calculations and safe removal, propping, capping any redundant flue with ventilation to prevent damp, and replastering so there is no trace the breast was ever there in your Morden home.
Combining the work with other jobs
A chimney breast removal makes a mess of the wall, the floor and the plaster in whatever room it happens in, so it is worth doing at the same time as anything else that room needs. If the house is being rewired, the electrician can chase and run new cables while the wall is open rather than cutting into fresh plaster afterwards. New skirting, a replastered ceiling or a new floor all fit naturally into the same programme.
On the 1930s streets around Morden Hall Park and the St Helier estate, the common pairing is a breast removal downstairs with a knock through between the two reception rooms, since both need propping, an engineer and building control in any case. Doing them together means one set of notices, one inspection sequence and one round of making good. Doing them two years apart means paying for the disruption twice and living through it twice as well.
