There is no safe way to leave a stack unsupported, however small it looks from below. In Romford's interwar semis the masonry above a removed breast is picked up on a steel beam bearing onto padstones, designed by the engineer we appoint. We prop, cut, install, and then have building control inspect the result.
Removing a chimney breast in Romford's interwar semis
Most Romford semis still have their original chimney breasts in the front reception and main bedroom, and in these paired 1930s houses the stack sits within the party wall shared with the neighbouring property. Because the breast helps carry the masonry above, we never start swinging a hammer until a structural engineer has assessed exactly what the stack is loading.
On the ground and first floors we support the retained stack above with steel gallows brackets bolted into the sound party wall brickwork, or a small beam where brackets are unsuitable. Where the stack runs full height and is no longer wanted, we often remove the whole thing and make the roof good, capping any redundant flue with ventilation to stop damp.
Party wall and building control in RM1
Because the chimney stack in a Romford semi generally sits in the shared party wall, removing the breast or bolting gallows brackets into that wall is notifiable under the Party Wall Act, so you serve notice on your neighbour before work begins. It reassures both households that the shared structure is being handled correctly and on a documented basis.
The structural support itself is notifiable under the Building Regulations, and Havering Council's building control inspects and signs it off. We manage the lot: the engineer's assessment, safe propping and removal, the gallows brackets or beam, capping the flue, and replastering so there is no trace the breast was ever there.
Old gas fires and back boilers in RM1
Interwar Romford houses very often still have a gas fire in the front room, sometimes with a back boiler sitting behind it in the builder's opening. Neither can simply be pulled out as part of the demolition. The appliance has to be disconnected and the supply capped by a Gas Safe registered engineer, and where a back boiler is removed the heating system it served has to be reworked or replaced.
The flue matters as much as the appliance. A gas fire may have been fitted with a liner dropped down the original flue, and that liner needs withdrawing rather than being buried in the wall. If any appliance elsewhere in the house still uses the same stack, its flue has to stay intact and be tested afterwards. We establish what is connected to what at the survey, so the gas work is booked in rather than holding up the demolition.
Aerials and cables fixed to the stack
Look up at a Romford semi and the chimney is usually carrying more than smoke. A television aerial is lashed to the stack, often a satellite dish alongside it, and the cables run down under the tiles or along the wall to the front room. If the stack is coming down, all of that has to be dealt with before the masonry does, not improvised on the day, and somewhere else has to be found for it that still gives a decent signal from the transmitter.
That may be a wall bracket on the flank, a pole on the gable, or in some RM1 houses a loft aerial where reception allows it. The dish needs a clear line of sight, so its new position is chosen rather than guessed. Two further checks matter: whether your neighbour's aerial is also fixed to the same shared stack, which changes the conversation entirely, and whether any cable entry left behind is properly sealed once the roof is made good, since an open hole is how water finds a loft.
- Ceiling and joist support where the breast carried them
- Ground floor removal with the upper stack fully supported
- Rubble bagged and carried out rather than dropped inside
- Soot and debris contained with screens and sheeting
- Flue capping with ventilation to keep the stack dry
