New apartments by the canal have no chimneys, while the older terraces near Kew Bridge carry stacks that were capped decades ago and then forgotten. Those are the ones we take out. Masonry left above is carried on engineered steel, the flue is vented, and building control approves the work before anything is closed up.
Supporting the retained stack in Brentford
Not every Brentford home has a chimney, but where one survives, in a period terrace or a warehouse conversion that kept its original brickwork, the breast usually carries masonry above it. Removing the lower breast without supporting that weight is dangerous, so we start with a structural engineer's assessment of exactly what the stack is holding and how the load should be carried once the breast is gone.
On a lower floor we support the retained stack with steel gallows brackets bolted into sound masonry, or a small beam where brackets are not suitable. Where the stack runs full height and is genuinely redundant, it is often cleaner to remove the whole stack and make good the roof. We cap and ventilate any disused flue to stop condensation and damp, then replaster so there is no sign the breast was ever there.
Party wall and building control in TW8
In Brentford's period terraces the chimney stack frequently sits within the party wall shared with the house next door, which makes removal notifiable under the Party Wall Act. Fixing gallows brackets or altering that shared wall affects your neighbour's property, so you serve the notices before work begins and keep the process straightforward for both sides.
The structural support itself is notifiable under the Building Regulations, so Hounslow Council building control inspects and signs off the work, not the planning department. If you own a conversion flat rather than a house, the leasehold picture applies too, and we secure the freeholder's consent and coordinate with the managing agent. Either way, we manage the engineer's design, safe removal and the certificate as one package.
Access along the canal and river
Brentford splits into two kinds of job as soon as access is considered. In the older terraces off the High Street and around Kew Bridge, front doors open almost onto the pavement, so a skip needs a Hounslow licence and a lit barrier overnight, and the barrow route is short but very public. We load in shorter bursts and keep the footway swept, since these streets carry heavy foot traffic between the station and the river.
The canal and riverside blocks work differently. Access runs through a controlled entrance and a shared corridor, and rubble cannot cross a residents' lobby without protection down. We bag the brick, use the goods lift where the building has one and agree loading times with the management. Neither situation changes the structural design, but both change how long removal takes, and we price that time honestly at survey. We also agree a single delivery slot for the steel rather than several, which keeps disruption at the entrance to one short window.
