Why Irish chimneys fail

  • 268,078homes built before 1946
  • 163,182homes heated mainly by solid fuel
  • 1,458 mmof rain a year in Castlebar, Co. Mayo
  • 753 mmin Dublin city centre, the driest county town

A chimney is the most exposed masonry on a house. It stands above the roof with weather on four sides, hot on the inside and wet on the outside, and nobody sees it up close for decades. Three things wear it out: rain driven into the joints, frost opening them further, and the acids in smoke working on the mortar from inside the flue.

Two things decide how hard a chimney has worked. The first is age: 268,078 Irish homes were built before 1946 (Census 2022), and their stacks were built in lime mortar with no clay liner in the flue. The second is use: 163,182 households still heat mainly with coal, turf or wood, so the flue is hot every day of the winter. Offaly has the highest share, 35% of homes, and Dublin the lowest at 0.6%.

Questions people ask

How much does chimney repair cost in Ireland?

Most chimney repairs cost €200 to €1,500. Repointing a stack is €300 to €1,500, new lead flashing €400 to €1,800, a flue liner fitted €800 to €2,500 and a full stack rebuild €1,500 to €4,500. The cost guide has every job.

Why is my chimney leaking?

Usually the lead flashing where the stack meets the roof, or cracked flaunching round the pots. Less often it is the mortar joints or a missing cowl. Where the damp shows tells you which.

Do I need scaffolding?

On a two-storey house, nearly always. Scaffolding for a chimney is €350 to €1,200 on a two-storey house, on top of the repair. On a bungalow most work is done from a roof ladder or a small tower.

Repoint or rebuild?

Repoint when the bricks are sound and only the joints have gone. Rebuild when the stack leans, bulges or has loose bricks. See chimney rebuilds.

Who repairs chimneys?

A roofer or a builder who does chimney work, with scaffolding and insurance. A chimney sweep cleans and inspects the flue but does not rebuild or repoint. See who does what.

Is the stack mine or shared?

On a semi or a terrace the stack usually sits on the party wall and is shared. Each owner looks after their own flue, and the stack itself is repaired by agreement.

Do you cover my county?

Yes, all 26. Each request goes to one chimney repair company that covers your county. See every county.

Who comes out?

One chimney repair company that covers your county. One company only, not a list.
