What chimney breast removal involves in Northumberland
Chimney breast removal is taking out the projecting brickwork that houses the flues from fireplaces, usually to gain floor space or straighten a wall. If any of the breast or stack above stays in place, it must be carried on steel or another support the engineer designs and building control accepts, so it is never left unsupported.
Across Northumberland, chimney breast removal usually comes up when people want more light, a better layout or a way through to a new extension. Coverage takes in Blyth, Cramlington and Ashington and everywhere in between. Whatever the reason, the beam is sized from calculations and the work is inspected before anything is covered.
Key points for your project
- In England and Wales, cutting away a chimney breast attached to a party wall is notifiable work under the Party Wall etc. Act 1996. Notice must be served on the neighbour before work begins, and their response decides whether party wall surveyors need to be appointed.
- If you remove the breast in a ground-floor room but want to keep a fireplace or the breast in the bedroom above, the steel underneath must be designed for that load. Its ends need solid bearings, which may mean pockets cut into the party wall.
- A chimney closed off at both ends can trap moisture and cause damp patches on the walls. Where part of a flue remains, a vent at room level and a ventilated cap on the pot keep air moving through it.
- Older fireplaces sometimes contain asbestos in flue linings, fire surrounds, hearth boards or heat-resistant panels. In buildings from before 2000, suspect materials are identified with a survey before removal so they can be handled correctly.
- Removing only the ground-floor breast leaves the upper breast and stack in place, so they must be supported. Taking the breast out on every floor and removing the stack above the roof avoids that load entirely, but involves roofing work and more disruption.
What happens, step by step
Look and measure
We check the wall, the span you want and what the wall is carrying, and photograph anything the engineer needs to see.
Design and price
Calculations come back from the engineer and we confirm your fixed written price, line by line.
Building control
We submit a building notice or full plans application to the local council's building control team, so approval is in place before the wall is touched.
Fit, inspect, finish
The work is propped and the steel installed and packed tight. After inspection the opening is boxed, plastered and left clean.

Building rules for Northumberland
In England, taking out a load-bearing wall or putting in a beam is building work under the Building Regulations 2010. It needs approval from building control, either the local council's building control team or a registered building control approver, through a full plans application or a building notice. Part A covers the structure and Part B covers fire safety, which is why steel in homes is usually fire protected.
Terraced and semi-detached homes often need party wall notices, because cutting into a shared wall to take a beam end is notifiable under the Party Wall etc. Act 1996. Allow at least two months for the notice period unless your neighbour agrees sooner.
Chimney breast removal by town
Local questions answered
Can I stay at home while the work is done in Northumberland?
Usually, yes. The work area is screened and floors are protected. The rooms either side of the opening are out of action for a few days, and there is some noise and dust while the masonry comes out.
How much does chimney breast removal cost in Northumberland?
As a guide, budget £1,400–£2,800 including VAT for chimney breast removal (ground floor) in Northumberland, based on published UK cost guides adjusted for prices in the North East (-7%). The exact figure depends on the span, what the wall carries, access and the finish, and is fixed in writing once the scope is agreed.
How long does chimney breast removal take?
A ground-floor breast with a steel beam supporting the masonry above usually takes two to four working days, including propping, fitting the steel, removing the brickwork and basic making good. Full removal from ground floor to roof takes longer because of scaffolding, roofing work and weather, and plaster needs time to dry afterwards.
Will removing a chimney breast cause damp?
It can if the remaining flue is sealed with no airflow, because moisture and condensation get trapped inside. Fitting a vent in the remaining breast or wall and a ventilated cap on the chimney pot keeps air moving. If the stack is removed and the roof made good, the risk from the flue goes away.
Can I remove a chimney breast on the ground floor only?
Yes, but whatever stays above must be properly supported. The structural engineer designs that support, usually a steel beam bearing onto walls that can take the load, and building control must approve it before work starts. Leaving an upper breast or stack without adequate support is dangerous and is a problem surveyors look for.
What is included in a chimney breast removal quote?
The itemised written quote covers the survey, engineer's calculations, building control, any party wall notices, temporary support, the steel or other support specified, removal and waste, venting or capping, and plastering and floor making good. Scaffolding and roof work appear as separate lines where the stack is involved, and the price is fixed in writing once the scope is agreed.
Which towns in Northumberland do you cover?
We cover towns including Blyth, Cramlington and Ashington, plus the villages and smaller towns around them.
