About our chimney breast removal service in North Ayrshire

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 standards accepts, so it is never left unsupported.

We carry out chimney breast removal throughout North Ayrshire, for homeowners, landlords and builders who need the structural part done properly. Towns we cover include Irvine and Kilwinning, among other places in the area. You get an itemised written quote that shows the calculations, approvals, steel, labour and finishing as separate lines.

Worth knowing before you start

  • 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.
  • 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.
  • 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.
  • The price depends on how many floors the breast spans, whether the stack is kept or removed, the support method the engineer specifies, roof and scaffold work, and how much rubble needs taking away. Each is listed separately in the quote.
  • 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 standards must approve before work starts.

What happens, step by step

  1. Free visit

    A short visit to North Ayrshire to see the job, agree what you want and check the bearings, floors and services that affect the design.

  2. Calculations

    The engineer's calculations and a simple drawing are prepared for your opening and shared with you before anything is ordered.

  3. Building warrant

    A building warrant is applied for from North Ayrshire Council, and work starts only once the warrant has been granted.

  4. Steel in, made good

    On site we prop, open up, fit and pack the steel, then fire protect, box in and plaster once the inspection is done.

Approvals in North Ayrshire

Scottish rules are stricter on timing than in England: the building warrant must be in place before the wall is touched. We prepare the application with the engineer's calculations and submit it to North Ayrshire Council. The finished work is then certified and a completion certificate submitted for acceptance.

There is no party wall notice system in Scotland. Instead, check your title deeds and, for flats, the tenement management scheme, and talk to neighbours early if the beam bears into a shared wall.

Local questions answered

Can you work on older or listed homes in North Ayrshire?

Yes. Older homes often have lime mortar, timber lintels or shallow footings, which the engineer allows for. Listed buildings need listed building consent for internal structural changes as well as building regulations approval, and that must be in place first.

What happens at the survey visit in North Ayrshire?

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.

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.

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 standards confirm what is possible.

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 standards must approve it before work starts. Leaving an upper breast or stack without adequate support is dangerous and is a problem surveyors look for.

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 standards 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.
