What chimney breast removal involves in Lancashire

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.

We carry out chimney breast removal throughout Lancashire, for homeowners, landlords and builders who need the structural part done properly. We work in Blackburn, Burnley and Leyland and the surrounding villages. You get an itemised written quote that shows the calculations, approvals, steel, labour and finishing as separate lines.

Key points for your project

  • 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.
  • 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.
  • 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.
  • 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.
  • 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.

How the job runs in Lancashire

  1. Survey in Lancashire

    We visit, look at the wall and what sits above it, measure the opening and note services, access and how the steel can be brought in.

  2. Engineer's design

    A structural engineer sizes the beam, padstones and any posts, and sets out the temporary support needed while the wall is out.

  3. 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.

  4. Install and sign-off

    Props go in, the opening is formed, the steel is set and packed, building control inspects it, and we make good.

Building rules for Lancashire

Structural openings in English homes need building regulations approval before work starts. The local council's building control team can deal with it, or you can use a registered building control approver. Either way the steel is inspected before it is covered, and a completion certificate is issued at the end. Keep it safe for when you sell.

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.

Questions about chimney breast removal in Lancashire

Do you cover Lancashire for chimney breast removal?

Yes. We carry out chimney breast removal in Lancashire. Book a free survey visit and we will check the wall, arrange the engineer's calculations and send an itemised written quote.

What happens at the survey visit in Lancashire?

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.

Should I remove the chimney stack as well?

It often makes sense if the breast is coming out on every floor, because then nothing is left to support. It needs scaffolding and roof repairs, and in terraces the stack is often shared, so your side may not be removable without affecting your neighbour's. The engineer and building control confirm what is possible.

Do I need building regulations to remove a chimney breast?

Yes. Removing all or part of a chimney breast is structural work. In England it needs building regulations approval through a full plans application or building notice, and in Wales an application under the Welsh regulations; in Scotland a building warrant is needed before starting; in Northern Ireland an application goes to council building control. We prepare and submit this with the engineer's calculations.

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.

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 Lancashire do you cover?

We cover towns including Preston, Burnley, Blackburn and Blackpool, plus the villages and smaller towns around them.
