Chimney breast removal with gallows bracket or beam support in Bermondsey. Trusted, professional, 30+ years' hands-on experience.
In the converted warehouses off Bermondsey Street a redundant flue can run several floors, and sealing it badly leaves a cold, damp shaft behind your plaster. We cap it at the head, vent it low down, and reinstate the wall properly. Masonry above is supported on steel designed by the engineer we appoint for the job.

Most of Bermondsey's new-build riverside apartments never had chimneys, but plenty of the converted warehouses and older buildings around SE16 retain original breasts, and homeowners often want them gone to free up floor space in a tightly planned flat. Because a breast helps carry the masonry above it, we never simply cut one out. An engineer first establishes what the stack weighs and what is bearing on it before we design the support.
On a lower floor with a stack still running above, we support the retained masonry on steel gallows brackets bolted into sound brickwork, or a small beam where brackets are unsuitable. Where the stack runs full height and serves nothing, we more often remove it entirely and make good the roof. Leaving a stack unsupported is never an option, whatever the room below looks like.
In converted Bermondsey buildings the chimney stack frequently sits within a party structure shared with the flat next door, so removing the breast or fixing gallows brackets into that wall is notifiable under the Party Wall Act and you serve notice on the affected neighbour first. As the flat is leasehold, the freeholder's licence to alter is needed too, and the managing agent will want the engineer's details on file before consenting.
The support work is controlled under the Building Regulations, so Southwark Council's building control inspects and certifies it; this is not a planning matter. We manage the engineer's design and the freeholder consent, remove and prop the breast safely, cap and ventilate any redundant flue to prevent damp, and replaster so there is no sign the breast was ever there.
A Bermondsey warehouse conversion adds a layer a house does not have, because everything you take out has to travel down through a shared building. The managing agent will want working hours agreed, usually a weekday window, the lift protected or kept clear of rubble, and evidence of our insurance on file before we are let through the door. We arrange all of that ahead of the start date rather than on the morning. Neighbouring flats above and below are told the dates in advance, since the noise in a converted building travels through the structure rather than the air.
Brick from an old flue is heavy and dusty, so it leaves in sealed bags rather than open barrows, through the service entrance at agreed times. Original features complicate the making good. Exposed brickwork, cast iron columns and timber beams are often part of what the conversion was consented on, so we agree with you and the agent what is reinstated in matching brick and what is simply closed up.
Bermondsey homeowners choose GS Renovation because we treat chimney breast removal as the structural job it is.

FAQ
Work from a scoped quotation, never from a headline rate. Once we have surveyed the SE16 property we can tell a Bermondsey homeowner what chimney breast removal genuinely involves there, including the making good that warehouse-conversion and new-build construction usually needs. GS Renovation itemises every line so the budget you set actually holds. Homeowners right across Southwark get the same treatment. Email info@gsrenovationltd.co.uk with the SE16 address and we will book a free Bermondsey survey. As a rough guide, chimney breast removal in London costs roughly £1,500 to £2,500 for a single floor where gallows brackets are accepted, or £2,200 to £3,250 where a steel beam is needed, which is the more common route now that LABC has withdrawn its standard gallows detail; two floors run £3,000 to £5,000 (indicative London ranges, MyBuilder and Checkatrade, 2026). Your figure depends on the size, specification and condition of the property, which is why we survey before quoting.
You hear it from us first, with the reason and the revised dates. If chimney breast removal at your SE16 property runs beyond the programme, GS Renovation explains whether the cause is a discovery in a warehouse-conversion and new-build structure, a Southwark Council inspection slot or something of ours. Fixed-price work does not become more expensive because it took longer. The Bermondsey updates continue weekly regardless. Ring 07472 424 226 and GS Renovation will explain how an SE16 overrun is handled.
We hand over, clear the site, and stay contactable. The chimney breast removal work at an SE16 address ends with a final Southwark Council inspection, the certificate you will need when the Bermondsey property is sold, and a walk round with your project manager. GS Renovation then holds the five year guarantee on installations. Ring 07472 424 226 if anything needs looking at afterwards, anywhere in Southwark. Aftercare in Bermondsey goes to the same Southwark team.
No. Removing the breast on one floor is common in Bermondsey, provided what remains above is properly supported. Taking out the full stack including the roof section avoids the support question but brings roof works and making good with it. We price both for the SE16 address.
That stock is our core work. Chimney breast removal in the streets around SE16 is familiar enough that GS Renovation knows which parts of a Bermondsey house tend to hide problems, and prices for them instead of discovering them later. Southwark Council building control is coordinated by us throughout. Ask for references anywhere in Southwark. Ask on 07472 424 226 what chimney breast removal typically uncovers in a Bermondsey house near an SE16 address, and what it costs.
Only with the freeholder's written licence to alter. In an SE16 conversion the breast is very often part of the building's original load-bearing brick shell rather than a partition inside your demise, which means it carries floors above you. Your lease will require consent and usually the landlord's surveyor's approval of the engineer's design. We prepare the technical package that consent depends on and build to it once granted.
Yes, SE16 included, along with every other postcode in Bermondsey. Chimney breast removal is not priced differently by street, and GS Renovation is usually working somewhere in Southwark already. Familiarity with the recent developments and converted commercial buildings turned over to flats around that postcode is what keeps a quotation accurate. Ring 07472 424 226 and we will confirm your address in a minute. The survey that follows is free and carries no obligation. Aftercare and snagging visits across Southwark are just as routine.
