Chimney breast removal with gallows bracket or beam support in Rickmansworth. Trusted, professional, 30+ years' hands-on experience.
GS Renovation removes chimney breasts in Rickmansworth houses, on one floor or through the full height, with whatever remains above properly supported. The support method is set by the structural engineer we appoint rather than chosen off a shelf. Building control applications and inspections are coordinated for you, and quotations are free and without obligation.

It is treated as demolition, not just alteration. In the Moor Park conservation area, conservation area consent is needed for the demolition of buildings and in some cases for the demolition of parts of buildings, including chimneys. The Moor Park conservation area was designated on 18 May 1995. That consent sits with the council and is settled before the breast comes out, not afterwards.
Where demolition is proposed because of the poor condition of a building, the council asks for the application for conservation area consent to be accompanied by a structural survey. We do not produce that survey. What we can do is tell you what we find when we open up, and build to whatever the engineer specifies once the consent position is clear. Starting the demolition and asking the question later is the expensive order to do it in.
What it controls is what is seen from outside, not what happens inside. Rickmansworth was designated a conservation area in 1974 and the area was extended in 1980 to take in the Victorian development of the town. Taking a breast out of a room is an internal alteration, and internal work is not itself controlled by the designation. The designation reaches the stack above the roof, the pot and the roofline.
That distinction is worth settling early because it decides the shape of the job. Removing a breast on the ground floor while leaving the stack in place means the stack has to be carried, either on gallows brackets bolted back into sound brickwork or on a steel beam. Which of those is acceptable is decided by the engineer after inspecting the brickwork above, and the council may have a view on anything that changes what is seen from the street.
Hertfordshire Building Control lists foundations, damp proofing and structural issues among the aspects of construction it checks, and applications are submitted through its website. We make the application and book the inspections as part of the job. The inspection that matters comes while the brackets or the beam and their fixings are still open to view, so nothing is boarded or plastered until it has been seen.
On cost, the indicative London ranges published by MyBuilder and Checkatrade in 2026 put a chimney breast removed on one floor with gallows brackets accepted at £1,500 to £2,500. The same removal is put at £2,200 to £3,250 where a steel beam is needed instead. Removal across two floors is put at £3,000 to £5,000. Those are guides, not our prices. Our quotation is free and based on what we find at the survey.
In parts of Rickmansworth a chimney breast is two jobs at once: a structural support decision and, in the Moor Park conservation area, a demolition consent question. GS Renovation settles both before anything is cut, appointing the engineer, coordinating building control, and pointing you to a heritage or survey professional where a contractor is not the right person.

FAQ
Budget for structure, trades and approvals separately and you will not be caught out. That is how the chimney breast removal quotation for a Rickmansworth property is laid out, so each element can be checked or deferred. The engineer's fee, where the design needs one, sits on the WD3 quotation too. GS Renovation explains all of it before any commitment across Rickmansworth. Ring 07472 424 226 and GS Renovation will show how the WD3 lines are built up. 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.
It stays in use, and that constrains the work. In a shared stack the neighbour's flues run within the same brickwork, so removal on your side has to leave theirs intact, sound and weathertight. Talbot Road, Wharf Lane and Norfolk Road form an area of workers' terraced housing, where a breast can sit on the party wall. Cutting into a party structure is notifiable under the Party Wall etc. Act 1996, so notice goes to the neighbour before any support detail is built.
Yes, and it takes the support question away, because nothing above is left needing to be carried. What it creates is external work. The roofline changes where the stack comes down, so the conservation area designation of 1974, extended in 1980, becomes the relevant control rather than the building regulations. The roof is closed with matching materials, and the design code names slate and concrete tiles as the roofing materials of the plan area.
Yes, ventilate it at both ends. A sealed flue with no air movement collects moisture, and salts in old brickwork then bring damp through to the face of the breast. A capped pot that still breathes, plus an air brick at the bottom, keeps air moving. Damp proofing is among the aspects of construction Hertfordshire Building Control lists as checked, so it is worth doing to a standard rather than blocking the opening with a board.
The hearth does, down to floor level, and the footing below is a decision for the engineer. A breast sits on its own footing, wider than the breast itself, and leaving it in the ground is acceptable where nothing new bears on that spot. Where it obstructs a new floor build up, it is broken out to the depth needed. Foundations are among the aspects Hertfordshire Building Control lists as checked, so the inspector will want to see what was done.
The projection plus both alcoves, turned into one flat wall you can measure and furnish. In the modest Victorian terraced housing the 1993 appraisal describes along Bury Lane, that is the difference between a room that takes a sofa on the chimney wall and one that does not. What you give up is the flue, so a wood burner or a future stove is off the table. Decide that before the brickwork goes, not after.
