Chimney Breast Removal Havering

Havering is mostly 1930s semis and postwar estate houses, where stacks are shorter and lighter than in inner London terraces, plus larger detached properties that often have several. The support needed varies accordingly. A structural engineer calculates it for the house in question, and we install the steel and finish the room.

In Havering, removing a breast on one floor typically costs £2,200 to £3,250 on a steel beam, and £3,000 to £5,000 across two floors (indicative London ranges, MyBuilder and Checkatrade, 2026). GS Renovation Ltd, a building contractor based in Potters Bar, does the work in Havering.

How the job runs

1. Free site survey at your Havering address: which floors the breast runs through, a shared stack, any live flue.
2. The engineer we appoint designs the support, and the work is registered with Havering Council building control or an approved inspector. On a shared wall you serve the party wall notice as building owner; we supply the drawings.
3. The floor above is propped and the breast comes down in courses from the top; what remains sits on the support the engineer specified.
4. Building control inspects the support before it is covered. We make good, and the completion certificate follows.

Chimney breasts in Havering's 1930s semis

Most of Havering's interwar homes were built with chimney breasts in the front reception and back kitchen, and in the borough's semi-detached houses those stacks and flues usually sit within the party wall shared with next door. Because the breast helps carry the masonry above, we begin every job with a structural engineer's assessment of exactly what the wall is holding before anything is taken out.

On the lower floors we support the retained stack on a steel beam bearing into the party wall, or on gallows brackets bolted into it only where the engineer and building control accept them. In taller houses, or where you want the full breast gone through both floors, we more often remove the whole stack and make the roof good, so nothing is ever left hanging unsupported.

Housing in Havering

The Council Tax list puts Havering at about 108,680 homes, 26% flats against 74% houses; 5% went up before 1919, 36% between the wars and 59% after 1945. The shared stack of a semi in Havering means a party wall notice before removal, and 29% of homes here are semi-detached.

Havering chimney stacks, satellite dishes and roof rules

Before a Havering chimney breast comes out, look at what is fixed to the stack above the roof. An aerial or a dish on the chimney has to move if the stack comes down, and in the Havering-atte-Bower Conservation Area an Article 4 Direction means planning permission is required for satellite dishes. There, a dish moving from the chimney to a wall is a planning matter, not a quick visit from the aerial fitter. Outside that area the new position is still worth agreeing before the scaffold goes up, so the cable can be run inside while the breast is open and before any plaster goes on.

The Gidea Park Article 4 Direction applies to dwelling houses within the Gidea Park Conservation Area and was confirmed on 24 June 2016. It removes Class C permitted development rights for other alterations to the roof of a dwellinghouse to the front and sides. Taking only the breasts out inside the house leaves the roof alone. Taking the whole stack down does change the roof. Whether removing a stack on a front or side slope counts as one of the alterations the direction covers is a question for Havering planning, so ask before the roofer quotes. Keeping the stack and carrying it on steel inside the house avoids the question.

Party wall and building control in RM postcodes

Because Havering's semis and terraces share a party wall with the neighbouring home, and the chimney stack usually sits within it, removing a breast or bolting on gallows brackets is notifiable under the Party Wall Act. You serve notice on the neighbour before work begins, so the shared wall is dealt with properly and there are no disputes later.

The structural support is controlled under the Building Regulations, and Havering Council's building control signs it off. No planning permission is needed for this internal work, though a listed house needs listed building consent. We manage the lot: appointing the engineer who produces the calculations, safe removal and propping, capping any redundant flue with ventilation against damp, and replastering so there is no trace the breast was there.

Postwar houses and their lighter flues

Havering is not all 1930s brick. The postwar estates around Harold Hill and the borough's later council-built housing often used precast concrete flue blocks or a slim brick stack rather than the deep breast of an interwar semi, and some have no true breast at all, only a shallow chimney block set against the wall. The support question in those houses is completely different, and in a fair number of cases far simpler.

It still has to be checked rather than assumed. We establish what the flue is built from, whether anything above bears on it, and whether a back boiler or gas fire was ever fitted, because the supply must be capped by a Gas Safe engineer before anything comes out. Where the block is genuinely non-structural, removal is quick. Where it turns out to be carrying part of the roof, the engineer designs support in the usual way.

When the wall is ready to decorate

New plaster over a removed breast is not ready for paint the moment it stops looking wet. It holds a lot of water, and even in a Havering house with the heating running it wants a proper stretch of time before it is dry through, longer in winter and longer again across a big wall in a detached property where two breasts have come out on the same elevation. Paint it early and the finish flakes.

The first coat should be a thinned mist coat of contract emulsion, which soaks in and gives the topcoats something to grip. Wallpaper wants longer still, and heavy vinyl paper hung on green plaster is the commonest reason a new wall ends up being stripped again. If the room has a textured ceiling running up to where the breast stood, mention it early, because matching an existing pattern is a different task from a flat patch.
