About our chimney breast removal service in Sevenoaks

Our chimney breast removal service in Sevenoaks covers everything from the first visit to the completion paperwork. We also work in nearby Maidstone, roughly 14.2 miles away. Postcode districts we cover here include TN13 and TN14.

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.

Key points for your project

  • If you remove the breast in a ground-floor room but want to keep a fireplace or the breast in the bedroom above, the steel underneath must be designed for that load. Its ends need solid bearings, which may mean pockets cut into the party wall.
  • 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.
  • 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.
  • 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 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 Sevenoaks

  1. Free visit

    A short visit to Sevenoaks 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 the local council's building control team, 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.

Building control and neighbours in Sevenoaks

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.

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.

Local questions answered

What happens at the survey visit in Sevenoaks?

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 much does chimney breast removal cost in Sevenoaks?

As a guide, budget £1,700–£3,350 including VAT for chimney breast removal (ground floor) in Sevenoaks, based on published UK cost guides adjusted for prices in the South East (+12%). The exact figure depends on the span, what the wall carries, access and the finish, and is fixed in writing once the scope is agreed.

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.

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.

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.
