About our chimney breast removal service in Ballymoney

We carry out chimney breast removal in Ballymoney, covering the BT53 postcode district. We also cover the surrounding towns and villages in Causeway Coast and Glens. The job starts with a free survey visit so the engineer's calculations are based on your actual walls, floors and loads.

Chimney breasts take up a surprising amount of room, especially in the kitchens and bedrooms of older terraces and semis. Removing one is common, but it is structural work: the breast usually continues upstairs and up through the roof, and in terraces the stack is often shared with the house next door.

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.
  • 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.
  • 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.
  • 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.
  • 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.

Building rules for Ballymoney

Building control in Ballymoney is run by Causeway Coast and Glens Borough Council. Beams and new openings are controlled work under the Northern Ireland regulations, so we apply before anything is removed and the steel is inspected before it is covered.

The Party Wall etc. Act does not extend to Northern Ireland. Shared walls are dealt with under your title and the general law, so we recommend agreeing access and the work with your neighbour before it starts.

Chimney breast removal near Ballymoney

Local questions answered

Do you also work near Ballymoney?

Yes. We also cover nearby towns including Coleraine, Portrush, Ballycastle and Ballymena.

Can I stay at home while the work is done in Ballymoney?

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 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 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.
