Chimney Rebuild Cost Ireland — What To Expect
Every chimney is different. This guide covers what affects the cost, typical timelines, when insurance pays, and how to get a free assessment from Jonathon.
What Chimney Rebuilds Involve
A chimney rebuild is one of the most common repairs carried out after fire damage, storm damage, or long-term deterioration. The work involves dismantling the damaged section of the chimney stack, rebuilding it with new materials, and ensuring the flue system is safe and fully functional.
Partial Chimney Rebuild
A partial rebuild involves taking down only the damaged portion of the chimney — typically the top section above the roofline. The existing brickwork below the damage is left in place, and the stack is rebuilt from that point up with new bricks, mortar, chimney pot, and cowl. This is the most common type of rebuild and is suitable when the damage is confined to the upper portion of the stack.
Full Chimney Rebuild
A full rebuild is needed when the damage extends through the entire chimney stack above the roofline — or when the existing masonry is too deteriorated to build upon safely. The entire stack is dismantled down to roof level and rebuilt completely. This always includes new flashing where the chimney meets the roof, and typically involves relining the full flue.
What Is Included as Standard
When Jonathon rebuilds a chimney, the following is always included:
- Dismantling and safe removal of the damaged stack
- Rebuild with quality brick or block to match the existing property
- New chimney pot and cowl fitted
- Lead or modern flashing at the roof junction
- Chimney relining where required (flexible steel or clay)
- Waterproofing of the rebuilt chimney as standard
- Full clean-up and removal of all debris
- Certified completion report for insurance or records
What Affects Chimney Rebuild Cost
Every chimney is unique, and the cost of a rebuild depends on several factors. Here are the main things that influence the price.
Height and Size of the Stack
Taller chimney stacks require more materials and more labour. A single-storey chimney is less work than a two-storey stack, and a double chimney with multiple flues costs more than a single.
Access and Scaffolding
Most chimney rebuilds require scaffolding for safe access. The cost depends on the height, roof pitch, and whether scaffolding can be erected easily. Difficult access — such as steep roofs or properties with limited space — increases the cost.
Materials Required
The type of brick or block used, whether a new flue liner is needed, the type of chimney pot and cowl, and the flashing material all affect cost. Matching existing brickwork on older properties may require sourced or reclaimed materials.
Extent of Damage
A partial rebuild of just the top courses is significantly less than a full rebuild from roofline. The extent of damage is determined during the initial inspection and CCTV survey — what looks minor from outside may be more extensive internally.
Property Type
Period properties, listed buildings, and properties with shared chimney stacks (semi-detached or terraced) can involve additional complexity, specialist materials, or coordination with neighbours.
Relining Requirements
If the internal flue liner is damaged — which is common after chimney fires — the flue will need relining with a flexible steel liner or clay liner. This is often required even for partial rebuilds.
How Long Does a Chimney Rebuild Take?
Most chimney rebuilds are completed within a week. The exact timeline depends on the extent of the work and weather conditions, as masonry requires dry conditions to cure properly.
When Insurance Covers the Cost
If your chimney damage was caused by an insurable event, your home insurance policy will typically cover the full cost of the rebuild. Insurable events include:
- Chimney fire — creosote or soot igniting inside the flue
- Storm damage — high winds, heavy rain, or lightning causing structural damage
- Accidental damage — depending on your policy's accidental damage cover
Insurance claims typically cover the full scope of works including scaffolding, materials, labour, relining, flashing, waterproofing, and the certified inspection report.
Jonathon handles your insurance claim from start to finish.
From the initial CCTV survey and certified report to liaising with loss adjusters and completing the rebuild, you don't have to deal with the insurance company at all.
Insurance generally does not cover chimney damage caused by gradual wear and tear, lack of maintenance, or general ageing. However, if you are unsure whether your damage is covered, Jonathon can advise during the free inspection — and if it is claimable, he manages the entire process for you.
How To Get a Free Chimney Assessment
Jonathon provides free on-site chimney assessments across Carlow, Wexford, South Wicklow, Kilkenny, Kildare, and surrounding counties. The assessment includes:
- Full external inspection of the chimney stack, flashing, and pot
- CCTV camera survey of the internal flue
- Identification of all damage — visible and hidden
- A detailed written quote with the recommended scope of works
- Advice on whether the damage is covered by insurance
There is no obligation and no pressure. If the chimney needs work, you will receive a clear, honest quote. If it is an insurance job, Jonathon handles the entire claim process so you don't have to.
Why Waterproofing Is Included as Standard
Ireland's wet climate is one of the biggest threats to chimney masonry. Rain, wind-driven moisture, and freeze-thaw cycles gradually break down mortar joints and brick surfaces, leading to damp problems, crumbling masonry, and eventually structural failure.
That is why every chimney rebuild by J.Roberts includes waterproofing as standard. A breathable waterproof coating is applied to the rebuilt chimney, protecting the new masonry from moisture penetration while still allowing water vapour to escape from inside the flue. This significantly extends the life of the rebuild and prevents damp patches appearing on internal chimney breast walls.
This is included in the price — it is not an optional extra. Jonathon believes in doing the job properly the first time.
