Chimney Removal: The Stack, the Breast, or Both
Taking a chimney stack down to below the roof and slating over it costs €600 to €1,500 in Ireland, plus scaffolding. That is the outside job. Removing the chimney breast inside the house is a separate, structural job: whatever is left above the part you remove has to be carried on steel or a proper support, designed by an engineer.

Taking a stack down
- Scaffold up, the roof below protected.
- The stack taken down by hand to below the rafters. Nothing is dropped.
- The flue capped inside the attic with a vent.
- The gap in the roof timbered, felted and slated or tiled to match.
- The rubble taken away.
Before you remove anything
- Is it shared? On a semi or a terrace the stack usually sits on the party wall and carries your neighbour's flues too. You cannot take your half.
- Is anything still using it? A gas fire, a boiler or a neighbour's stove may vent through it.
- Is the house protected? On a protected structure or in an Architectural Conservation Area, removing a stack needs planning permission. Elsewhere, ask the council's planning office first: a stack is part of how the house looks from the street.
- Will the breast stay? If it does, it still needs a vent top and bottom.
Removal and the alternatives, priced
| Job | Typical cost | What moves the price |
|---|---|---|
| A stack taken down below the roof | €600 to €1,500 | Making good the roof over it |
| An unused chimney capped, with a vent | €300 to €900 | A cap on the pot, or the pot off and a slab on |
| Scaffolding for a chimney | €350 to €1,200 | Two storeys or three, a stack at the ridge or the eaves |
| A full stack rebuild | €1,500 to €4,500 | Size, height, matching brick or stone, a new lead tray |
Repair work on a house is at the reduced 13.5% VAT rate. Ask for a written price that includes it, and says whether scaffolding is in it.

Questions people ask
Is it cheaper to remove a stack than to repair it?
Often, if it needs everything. Removal is €600 to €1,500; a full rebuild is €1,500 to €4,500.
Can I remove the breast downstairs and leave it upstairs?
Only with the upper part carried on steel designed by an engineer. Never on timber or brackets alone.
Does removing a chimney affect the value of the house?
A working fireplace is a selling point in a period house. In a modern semi, few buyers miss a stack.
How long does a stack removal take?
A day or two, with the roof made good the same day it is opened.
What about the fireplace?
It can stay as a feature or be closed with a vent. The flue above it is capped in the attic.
