Chimney stacks sit at the highest and most exposed point of the house, so even a small job like fitting a cowl or re-flaunching a pot needs proper access. A chimney scaffold is built up from the ground and then over the roof to create a platform around the stack itself.
Typical chimney work includes repointing, rebuilding or reducing the stack, renewing the lead flashing, fitting cowls or bird guards, and taking a disused stack down.
What scaffold set-up you need
- A tower or independent scaffold up the elevation nearest the stack, then a roof saddle or birdcage around the chimney.
- Stacks on the party wall of a terrace or semi may need access from a neighbour’s side – the scaffolder will need their permission.
- Stacks in the middle of a roof slope need more tube and boards to reach, which shows in the price.
How much does it cost?
Chimney access usually adds £200–£400 to a standard elevation scaffold. A short-hire chimney scaffold on a two-storey house is often £600–£1,000 in the South East.

Tips
- Combine chimney work with any roof or gutter work to share the scaffold.
- If the stack is shared, speak to your neighbour early – the work may also need a party wall notice.
