Damp on the chimney breast, crumbling mortar, or a stack that looks like it’s leaning a touch — the chimney is where a huge share of Cork roof leaks begin, and “what will it cost to fix?” is the first thing every homeowner asks.

I’m Michael Casey, founder of Keystone Roofing. We repair chimneys across Cork City and County, from a single flashing renewal to a full stack rebuild on an exposed coastal property. Here are the honest 2026 ranges we quote, ex-VAT. All figures exclude VAT — check whether any quote you compare is ex-VAT or inc-VAT.

In short:

Most Cork chimney repairs run from a few hundred euro to a few thousand, ex-VAT. Renewing the lead flashing where the stack meets the roof is typically €650–€1,400; repointing or re-rendering is priced by the size of the stack; a partial or full rebuild costs more and is quoted after inspection. The inspection and written quote are free.

How much do chimney repairs cost in Cork?

Chimney work is priced by the job, not by a flat rate, because “chimney repair” covers everything from re-sealing one flashing to rebuilding a stack. The table below shows the 2026 ranges we quote across Cork, ex-VAT:

JobTypical cost (ex-VAT)
Lead flashing renewal (where stack meets roof)€650–€1,400
Repointing mortar jointsPriced by stack size
Re-rendering / re-capping the stackPriced by stack size
Cowl or cap fittedFrom a few hundred euro
Partial or full stack rebuildQuoted after inspection

Ranges exclude VAT. Scaffold or powered access, where the stack can’t be reached safely from the roof, is added on top.

A leak around the chimney is one of the most common roof repairs in Cork we carry out. If water is actively coming in, our 24/7 emergency roof leak repair line gets a roofer out to make it safe first.

What affects the cost of a chimney repair?

The price comes down to how much of the stack needs work and how hard it is to reach. The main factors:

  • Scope — re-sealing one flashing is cheap; repointing the whole stack, re-rendering, or rebuilding is progressively more.
  • Access — a stack reachable safely from the roof costs less than one needing scaffold or a powered platform.
  • Lead and materials — flashing is priced by the grade and length of lead; rebuilds by brick or stone and mortar.
  • Exposure — coastal stacks in places like Cobh, Crosshaven and Kinsale weather faster and often need more substantial work.

How do you know the chimney is the problem?

Damp on the chimney breast, staining on the ceiling near the stack, or a musty smell in the top bedroom are the classic signs. The usual culprits are failed lead flashing, eroded mortar joints, or cracked rendering — all of which let water track down inside the stack. We confirm the source first, often by drone roof inspection, before quoting. For the full diagnosis walkthrough, see our chimney leak diagnosis guide.

Repair or rebuild the chimney?

Most of the time, repair is enough. If the brickwork is sound, renewing the lead flashing, repointing the joints and re-rendering makes the stack weather-tight for decades at a fraction of a rebuild’s cost. A rebuild is only needed when the masonry itself has loosened or started to lean — common on older, exposed coastal stacks. We’ll always tell you honestly which one yours needs.

Frequently asked questions

Chimney Repair Cost in Cork 2026 — FAQs

01 How much do chimney repairs cost in Cork?

It depends on the work. Renewing the lead flashing where the stack meets the roof is typically €650–€1,400 ex-VAT; repointing or re-rendering is priced by the size of the stack; a partial or full rebuild costs more and is quoted after inspection. The inspection and written quote are free.

02 How do I know if my chimney is causing a leak?

Damp on the chimney breast, staining on the ceiling near the stack, or a musty smell in the top bedroom are the classic signs. The usual culprits are failed lead flashing, eroded mortar joints or cracked rendering. We confirm the source — often by drone — before quoting.

03 Can a chimney be repaired without rebuilding it?

Most of the time, yes. If the brickwork is sound, renewing the lead flashing, repointing the joints and re-rendering makes the stack weather-tight for decades at a fraction of a rebuild. A rebuild is only needed when the masonry has loosened or started to lean — common on older coastal stacks.

04 Does a chimney repair need scaffolding?

Only if the stack cannot be reached safely from the roof. Many chimney repairs are done from roof level; taller stacks, steep roofs or restricted access need scaffold or a powered platform, which is added to the quote. We confirm the access plan during the free inspection.
