The front bedroom of a Chadwell Heath house gains a full wall once the breast is out, which is usually enough for fitted wardrobes end to end. We prop and remove it, install the steel the engineer has specified, cap and ventilate the redundant flue, and plaster the wall ready for you to decorate.
In Chadwell Heath, removing a breast on one floor typically costs £2,200 to £3,250 on a steel beam, and £3,000 to £5,000 across two floors (indicative London ranges, MyBuilder and Checkatrade, 2026). GS Renovation Ltd, a building contractor based in Potters Bar, does the work in Chadwell Heath.

How the job runs
- Free site survey at your Chadwell Heath address: which floors the breast runs through, a shared stack, any live flue.
- The engineer we appoint designs the support, and the work is registered with Barking and Dagenham Council building control or an approved inspector. On a shared wall you serve the party wall notice as building owner; we supply the drawings.
- The floor above is propped and the breast comes down in courses from the top; what remains sits on the support the engineer specified.
- Building control inspects the support before it is covered. We make good, and the completion certificate follows.
Chimney breast removal in Chadwell Heath
Most interwar terraces and semis around Chadwell Heath still carry their original chimney breasts in the reception rooms and bedrooms, projecting into the space and eating into a room's usable width. In the terraces, and in many semis, the stack sits within the party wall shared with the house next door, so it is masonry that belongs, in part, to your neighbour as well as to you; in some semis it stands on the flank wall instead.
That shared arrangement is why we never simply knock a breast out. The brickwork above still needs to be carried, so removing a breast on the ground or first floor means supporting the retained stack on a steel beam bearing into the party wall, or on gallows brackets bolted into it only where the engineer and building control accept them for the load.
Housing in Chadwell Heath
About 9,660 homes are listed for Chadwell Heath, and the mix is 66% houses to 34% flats, with 48% built after 1945, 42% in 1919 to 1939 and 9% earlier. A terrace breast in Chadwell Heath usually sits on the party wall, so removal needs a notice, and 46% of homes here are terraced.
What building control looks for on a Chadwell Heath chimney breast
Chimney breast removal has its own line in the building control fee schedule issued by Be First Building Control for Barking and Dagenham, split into a plan check part and an inspection part. That tells you how the job is treated in Chadwell Heath: as a structural alteration with a design to check and a site stage to see, not as strip-out. The borough's building alterations page also names removing chimney breasts among the works it must be told about. So the support detail is submitted before the first brick comes out, and the inspection is booked for the moment the steel or brackets are fixed and still visible.
Before any of that, confirm what the projection actually is. Homes built in 2000 or later make up 12% of Chadwell Heath's housing, and not every boxed-out section of wall is masonry. In a newer home it may be a service riser, a boiler flue boxing or a studwork casing round a soil pipe, and none of those needs steel. In an older house it is brick with a flue inside, and the engineer checks whether the stack above has already been taken down by an earlier owner, because that changes the load the new support has to carry.
Party wall and support in RM6
Where the stack runs full height and is no longer used, the cleaner answer is often to remove it entirely and make good the roof, rather than leave a truncated stack carried on steel. Whichever route the engineer recommends, the retained masonry is never left unsupported at any point during the work, and the flue is capped with ventilation to keep the redundant chimney dry.
Where the stack sits in the shared party wall, removal is notifiable under the Party Wall Act, so you serve notice on your neighbour as building owner before work begins, using the drawings we give you. The structural support is controlled under the Building Regulations and the council's building control (Barking and Dagenham, or Redbridge for some RM6 addresses) signs it off. We coordinate the engineer's calculations and handle the propping and the replastering so no trace of the breast remains.
What the room gains once it goes
A Chadwell Heath house has modest bedrooms, and the breast usually sits in the middle of the party or flank wall, splitting it into two shallow alcoves that suit almost nothing. Take it out and you have one straight run of wall, typically three metres or more, which is enough for a full wardrobe line with sliding doors that do not foul the end of the bed.
Downstairs the effect is different. The through lounge in these interwar houses is often the only room where a fire is still used, so owners keep the ground floor breast and remove only the one above it. That returns the bedroom without losing the hearth. Where both go, the front room squares up and furniture finally sits flat against the wall. We talk through which floors to do before the engineer is briefed, because it changes the support design entirely. Losing the ground floor breast also frees the wall for a run of built in shelving either side of where the alcoves used to be.

FAQ
Frequently Asked Questions about Chimney Breast Removal Chadwell Heath
Which parts of a chimney breast removal project in Chadwell Heath cost the most?
On a chimney breast removal project in Chadwell Heath the approvals are a small line and the time on site the large one, within £2,200 to £3,250 for one floor on a beam (indicative). The cost of Barking and Dagenham Council or Redbridge Council building control approval of the steel carrying the retained stack is small next to labour, but skipping it costs a sale. The days on site are set by the property itself: removing one floor or two decides the support.
Is chimney breast removal different in a Chadwell Heath semi than a terrace?
The support usually is, yes. Some RM6 semis carry the stack on the flank wall rather than in the party wall, as the terraces do, which changes where a beam can bear and sometimes puts the brickwork on an external face exposed to weather. Bearing into a solid outer leaf needs the engineer to look at both the masonry condition and the thermal bridge left behind. The party wall duty still applies where the stack is shared.
Can only the ground-floor chimney breast come out of my Chadwell Heath house?
Yes, as long as what remains above is carried. Once the lower section goes, the bedroom breast and the stack above it are left unsupported, so they sit on new steel, or on gallows brackets only where the engineer and building control accept that detail. The engineer's calculations decide between the two, and props stay in place until the permanent support is proven.
What happens to the old flue after a chimney breast goes in Chadwell Heath?
It gets a vented cap on top and an air vent low down, so air keeps moving through it. Block a disused flue at both ends and the trapped moisture settles on cold brick, surfacing later as brown stains on the plaster of an RM6 bedroom. The pot is lifted off or capped with a ventilated cowl, and the lower vent is fitted before the room side is replastered.
Will I need paperwork for a Chadwell Heath chimney breast removal when I sell?
Yes: the completion certificate from building control. Removing a breast is structural work, and a buyer's solicitor will ask for evidence that the stack above was supported to an approved design. In RM6 that certificate comes from Barking and Dagenham Council or Redbridge Council, depending on the address, after the final inspection. Keep it with the engineer's calculations and any party wall award, because those three documents answer most of the questions a survey raises.
Does my neighbour get a say if our shared wall holds the chimney breast in Chadwell Heath?
Yes. A breast built into the party wall needs a party structure notice served at least two months before work starts. Your neighbour can consent in writing or dissent. A dissent is not a veto; it means surveyors are appointed and an award sets out how the work is done and what gets recorded. Serve the notice early, because the two-month clock only starts once it lands.
Could taking down a Chadwell Heath chimney stack need planning permission?
Only if the house sits in a conservation area. On the Barking and Dagenham side of RM6 there are four, and the one carrying the local name, the Chadwell Heath Anti-aircraft Gun Site Conservation Area, is a former World War II defensive position where eight large guns were sited. Check the council's map for your address. Inside any of the four, demolishing a building or structure in whole or part needs planning permission for relevant demolition (what the council's page still calls conservation area consent, a separate consent until 2013). Outside them, and unless the house is one of the borough's 45 listed buildings and structures, the stack is a building control and party wall question.
Can one application cover a chimney breast and a knock-through in Chadwell Heath?
Usually, yes. One submission can describe the chimney breast and the knock-through together, and the engineer can put the stack support and the new beam on the same drawing, so the inspector checks both against one set of calculations. The Be First fee schedule for Barking and Dagenham prices chimney breast removal as its own item, with separate lines for other work such as extensions. So ask building control how the combined job will be charged before you apply.
Are chimney breasts in pre-1919 Chadwell Heath houses built differently?
They can be. The VOA puts 9% of Chadwell Heath homes before 1919, and in houses of that age the breast may be solid brick bonded into a solid party wall, with flues from several fireplaces gathering into one stack. Taking out one breast can leave another flue running beside it, still in use or still connected to next door. The survey traces every flue through the house before the support is designed, so nothing live is cut.
