About our chimney breast removal service in Mangotsfield

If you live in Mangotsfield, chimney breast removal can usually be planned and priced after a single survey visit. Mangotsfield is around 9.9 miles from Bath, and we cover both. We cover BS15, BS16 and BS36, and we fix the price in writing once the layout and scope are agreed.

We cover the survey visit, structural calculations from a qualified engineer, building control, party wall notices through a party wall surveyor where needed, temporary support, removal, the steelwork and making good. Whether you are taking out the ground-floor breast only or the full height, the itemised written quote shows each stage.

Worth knowing before you start

  • 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.
  • Once the breast is gone, the wall behind it is often rough, sooty or uneven. It is cleaned back, dubbed out where needed and plastered flat, and the floor where the hearth sat is filled level to meet the surrounding boards or screed.
  • 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 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.
  • In terraces and semis the chimney stack usually serves both houses, with flues from each side rising together. You can generally only alter your own side, and the work must not weaken your neighbour's breast or flues, which is why party wall procedures often apply.

From survey to sign-off in Mangotsfield

  1. Free visit

    A short visit to Mangotsfield 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 control

    We submit a building notice or full plans application to South Gloucestershire Council, so approval is in place before the wall is touched.

  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 Mangotsfield

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 South Gloucestershire Council 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.

If the beam bears into a wall you share with a neighbour, the Party Wall etc. Act 1996 applies, and a party structure notice must be served at least two months before that work starts. We arrange this through a party wall surveyor.

Questions about chimney breast removal in Mangotsfield

Can you work on older or listed homes in Mangotsfield?

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.

Do you also work near Mangotsfield?

Yes. We also cover nearby towns including Kingswood, Yate, Bath and Portishead.

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.

Do I need my neighbour's permission to remove a chimney breast?

Not permission as such, but in England and Wales you must serve notice under the Party Wall etc. Act 1996 if the breast is attached to a party wall, and your neighbour can consent or dissent. You cannot remove their half of a shared stack. Scotland and Northern Ireland have no equivalent Act, so the title deeds and general law apply.
