GS Renovation removes chimney breasts across Mitcham, from the interwar terraces to the 1930s semis near Mitcham Common and Morden Hall Park. With more than 30 years of structural experience in CR4 and Merton, we take out redundant breasts safely, support the stack above and leave the room squared off and replastered.
Chimney breasts in Mitcham's period and interwar homes
Many Mitcham houses still carry their original chimney breasts on both the ground and first floors, taking up valuable space in rooms that no longer need an open fire. In the interwar semis and period terraces here, the stack is usually built into the party wall shared with the house next door. Because the breast helps carry the masonry above, we begin every job with a structural engineer establishing precisely what the stack and breast are supporting.
Where you remove a lower breast but keep the stack above, that retained masonry has to be picked up. We support it on steel gallows brackets bolted into the party wall, or on a small beam where brackets are unsuitable for the loading. In many Mitcham houses the whole stack is redundant, so the cleaner solution is to remove it in full, right up through the roof, and make the roof covering good and weathertight.
Party wall and building control in CR4
Because Mitcham's semis and terraces share a party wall with the neighbour, and the chimney stack usually sits within it, removing the breast or fixing gallows brackets affects that shared wall. That makes the work notifiable under the Party Wall Act, so we serve notice on the adjoining owner before starting. A stack is never left unsupported: the retained masonry is always carried on engineered brackets or a beam designed for the exact load above it.
The structural support is notifiable under the Building Regulations, so Merton Council's building control inspects and certifies it, and no planning permission is needed for this internal work. We manage the whole job: the engineer's calculations, the party wall notices, safe removal and propping, capping any redundant flue with ventilation to prevent damp, and replastering so there is no trace the breast was ever there.
