Chimney Breast Removal Hemel Hempstead

GS Renovation removes chimney breasts in Hemel Hempstead, on one floor or through the house, with whatever remains above properly supported. Nothing is cut until a structural engineer has designed that support, which is usually a steel beam on padstones, with gallows brackets only where the engineer and building control accept them. We coordinate the building control side from the first notice to the final inspection.

For Hemel Hempstead, on London-derived ranges 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; Hertfordshire work generally runs below that. GS Renovation Ltd, a building contractor based in Potters Bar, does the work in Hemel Hempstead.

How the job runs

1. Free site survey at your Hemel Hempstead 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 Hertfordshire 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.

Sign off comes from Hertfordshire Building Control, not the council

Dacorum Borough Council does not run its own building control service. Building control for the borough is provided by Hertfordshire Building Control, contactable on 01438 879990. Removing a chimney breast is notifiable work, because you are taking out something that is carrying load and leaving the rest of the stack above it. The engineer's design and the inspections both run through that route, and we handle the application and the appointments.

Whether the support is a steel beam, now the usual route since LABC withdrew its standard gallows detail in 2024, or gallows brackets where the engineer and building control accept them, is not a decision we make on site. It follows from the engineer's assessment of the load above and the condition of the wall any brackets would fix back to. We price both routes at quotation stage, so the figure does not move once the design comes back.

Written authority for demolition in the conservation area

It applies inside the conservation area boundary. In a Dacorum conservation area, written authority is needed to demolish or partly demolish a building larger than 115 cubic metres in volume, including some garden walls and chimneystacks. The Hemel Hempstead conservation area was originally designated on 7 October 1968, with an adopted boundary amendment on 21 January 2014, so the boundary is worth checking rather than assuming. Where a stack is coming down above roof level there, we establish the position with the council first.

Stacks and flues on a frontage

Those need planning permission inside the conservation area. In the Hemel Hempstead conservation area, installing, altering or replacing a chimney, flue or soil vent pipe on a wall or roof slope that fronts a highway and forms the principal or side elevation requires planning permission. A breast removal that ends with the stack taken down and the roof made good changes what is visible from the street, so we raise it at survey rather than when the scaffold is already up.
