GS Renovation removes chimney breasts in St Albans houses, on one floor or through two, with everything left above properly supported to a structural engineer's design. Older St Albans stock is concentrated in particular areas, and the breast you want out is carrying weight. We appoint the engineer and coordinate the building control inspections.
Where the older St Albans chimney stock sits
Chimney breasts belong to older housing, and two St Albans areas stand out in the figures. In Bernards Heath, 1,650 of 2,620 dwellings, 63.0 per cent, were built before 1945, the highest pre 1945 share of the 19 St Albans District areas with published VOA data. In the Verulam Park area, 780 of 3,190 dwellings, 24.5 per cent, were built before 1900.
In housing of that age a breast can run from ground floor to roof, with the stack still standing once a lower section comes out. That is the whole engineering problem. Whatever is removed has to be replaced with support, either gallows brackets bolted into sound masonry where the engineer accepts them, or a steel beam where the loads or the brickwork rule brackets out.
How St Albans compares with England and Wales
St Albans District has a lower pre 1945 share than England and Wales as a whole, which makes the older pockets worth identifying before you plan the work. 19,040 dwellings in the district, 30.0 per cent of the stock, were built before 1945, compared with 35.2 per cent across England and Wales. In the Clarence Park area, 1,060 of 3,600 dwellings, 29.4 per cent, were built before 1919.
Cost follows the method and the number of floors. Indicative London ranges, MyBuilder and Checkatrade, 2026, put a chimney breast removal on one floor at £1,500 to £2,500 where gallows brackets are accepted, and at £2,200 to £3,250 where a steel beam is needed. Removal through two floors runs £3,000 to £5,000. We quote after seeing the breast, the stack and the party wall position.
Get the new support inspected before anything is plastered over
If St Albans building control is not informed of the relevant stages of work, it may require the work to be opened up so that compliance with the Building Regulations can be checked. On a chimney breast that means exposing gallows brackets or a beam bearing after the room has been made good. We book the inspection while the support is still open to view.
The council's advice on unsafe structures points to the same discipline. St Albans City and District Council advises that if you are concerned part of your property may be dangerous, you should deal with it through properly qualified professionals such as structural engineers, architects and builders. We appoint the engineer, build to the design, and never produce structural calculations ourselves.

Trusted Chimney Breast Removal in St Albans

We appoint the structural engineer, build to the design, and book the building control inspection while the brackets or the beam are still visible.
