The big houses of Emerson Park can carry three or four stacks, while the 1930s semis nearer Hornchurch High Street have one apiece. Either way the breast is dead space you are heating and paying for. We remove it, carry whatever stays on engineer-designed steel, and leave the room square and freshly replastered.
Chimney breasts in Hornchurch semis
Many Hornchurch semis still carry their original 1930s chimney breasts serving open fires that have long been capped off. Homeowners in RM11 usually want the breast gone from a first-floor bedroom, or from the ground floor to open the space up. Because the breast helps carry the masonry and stack above, we never remove it without a structural engineer first confirming what is being supported and how the retained stack will be held.
Where you keep the stack above, we support it on galvanised steel gallows brackets bolted firmly into the party wall, or on a small beam where brackets are not suitable. On many interwar semis it is cleaner to remove the full-height stack entirely and make the roof good with new tiles and flashing. A retained stack is never left hanging unsupported.
Party wall and building control in RM11
In a Hornchurch semi the chimney stack typically sits within the party wall shared with the house next door. That makes removal notifiable under the Party Wall Act, and gallows brackets bolted into that shared wall affect it directly, so you serve notice on the adjoining owner before any work starts. It is a routine part of the job, not an afterthought.
The structural support is notifiable under the Building Regulations, and Havering Council's building control inspects the brackets or beam and signs the work off. We manage the lot: the engineer's design, safe removal and propping, capping any redundant flue with ventilation to prevent damp, then replastering so the room reads as if the breast was never there.
Gas fires, back boilers and room ventilation
A 1930s Hornchurch semi has usually had a gas fire in the front room at some point, and quite often a back boiler behind it feeding the heating. Before anything structural happens, the supply is disconnected and capped by a Gas Safe registered engineer and any redundant pipework is taken out rather than left buried in the wall. A back boiler also leaves a much larger builder's opening behind it than a simple fireplace does.
Ventilation is the part people forget about. The old appliance needed combustion air, so the room often has an air brick or a floor vent feeding it, and once the fire and the breast are gone that vent is just a cold draught, so it is closed up and made good. The retained flue above needs the opposite treatment, a cap at the head and a vent low down, so the shaft stays dry and does not stain fresh plaster.
