About our chimney breast removal service in Derry City and Strabane
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.
Looking for chimney breast removal in Derry City and Strabane? Towns we cover include Derry/Londonderry and Strabane, among other places in the area. Our teams handle the calculations, the building control approval, the propping and the steel itself, and leave the opening ready for plastering and decoration.
Worth knowing before you start
- Removing a ground-floor breast with steel support typically takes two to four working days. Full-height removal including the stack and roof repair takes longer and depends on scaffolding, roofing access and the weather.
- 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.
- Chimney brickwork is heavy and dirty. Even a single breast produces a lot of rubble and soot, so a skip or waste collection is planned in advance, and floors, stairs and furniture along the route out are protected.
- A flue still serving a gas fire, boiler or wood burner cannot be removed until that appliance is disconnected and an alternative arranged. Work on any gas appliance or pipe must, by law, be done by a Gas Safe registered engineer.
- Some owners remove breasts in the loft to make space for a conversion while keeping the stack on the roof. That leaves the stack carried at loft level on steel or another support, which the engineer must design and building control must approve before work starts.

Local questions answered
What happens at the survey visit in Derry City and Strabane?
We look at the wall, the floor and ceiling either side and what sits above, measure the opening you want, and note cables, pipes and access for the steel. It usually takes under an hour and there is no charge.
Can I stay at home while the work is done in Derry City and Strabane?
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.
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 downstairs and keep the fireplace upstairs?
Usually, as long as the upstairs breast and its flue stay intact and are carried on a support the engineer designs for that load. Building control must approve the arrangement. If the upstairs fireplace has a gas fire, any work on it or its supply must be carried out by a Gas Safe registered engineer.
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.
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.
