It's the first thing most people ask when they spot crumbling mortar on the stack or a damp patch on the chimney breast: what's it going to cost to put right? The honest answer is that there's no single fixed price — a bit of repointing on a low, easy-to-reach chimney and a full rebuild on a tall Victorian stack are worlds apart. But you deserve better than "it depends", so this guide lays out the real ranges you'll come across in Ireland and, more importantly, what actually drives the number up or down.
Use it to sense-check any quote you're given. And remember the golden rule with chimneys: the cheapest time to fix one is always now, before the water gets in.
Why access — not the brickwork — often decides the price
Here's the thing people don't expect: with chimney work, the masonry is frequently the smaller part of the bill. The chimney sits at the highest, most exposed point of the house, so getting to it safely is the challenge. A stack that can be reached from a scaffold tower off a flat area is a straightforward job. The same repair on a tall house, over a conservatory or on an awkward roofline can need full scaffolding erected — and that scaffolding can be a real share of the total.
That's why we'll nearly always suggest doing everything the chimney needs — repointing, flaunching, pots, flashing — in one visit while the access is up, rather than paying to get up there twice. It's also why an honest quote comes after a proper look, not off the top of someone's head down the phone.
Typical chimney repair costs in Ireland
These are broad guide ranges to give you a feel for it — not a quote. Your actual price depends on access, the size of the stack, and how much has failed. As a real example of the top end, a recent two-chimney restoration we did in Dublin — both stacks raked out, repointed, tops rebuilt and crack-stitched, with scaffolding — came to €13,500.
| Type of chimney job | What's involved | Guide range |
|---|---|---|
| Repointing a stack | Raking out failed joints and repointing in the right mortar | €600–€1,500 |
| Re-flaunching & new pots | Renewing the mortar bed around the pots; fitting new pots or cowls | €350–€1,200 |
| Lead flashing renewal | New lead flashing and soakers where the stack meets the roof | €400–€1,200 |
| Rebuilding a stack | Taking the stack down and rebuilding in matching brick or stone | €1,500–€4,000+ |
| Capping off an unused chimney | Ventilated cap/hood, or reducing the stack to roof level neatly | €300–€900 |
Add scaffolding on top of these where the access needs it. It's common for two or three of these jobs to be needed together — for instance, a stack that needs repointing usually needs the flaunching and flashing seen to at the same time.
What drives the cost up or down
When we look at a chimney and work out a price, these are the things moving the figure:
- Height and access. The single biggest factor. Reachable from a tower is cheap; needing full scaffolding around the house adds a lot.
- Repoint or rebuild. Raking out and repointing sound brickwork is far less than taking a leaning or cracked stack down and rebuilding it.
- How far the damage has gone. Surface pointing that's tired is minor. Mortar washed deep into the joints, a rotten flaunching or water already tracking inside means more work.
- Matching old brick or stone. On a period house, sourcing and matching reclaimed brick or the right stone takes time and care — but it's what keeps the repair looking right.
- Lead flashing. Old cracked cement fillets or worn lead let water in. Proper lead flashing costs more than a smear of mortar, and lasts decades longer.
- One stack or several. Doing two or three flues or stacks in one go while the scaffold is up is more efficient than separate visits.
- Listed or protected buildings. Conservation-standard work in lime, matched to the original, is more skilled and careful work.
Why waiting almost always costs more
Chimney problems don't stay still. Failed pointing and cracked flaunching let wind-driven rain into the stack. From there the water rots the flashing, soaks down through the brickwork and shows up as brown staining and damp on the chimney breast and ceiling inside. What could have been a modest repoint becomes repointing plus flashing plus re-plastering and decorating indoors — and, if it's gone far enough, structural work on a stack that's now leaning.
A quick look and a small repair early is always cheaper than a big one later. If you can see loose mortar, a tilting pot, a leaning stack or damp near the chimney inside, it's worth getting eyes on it.
Getting a fair quote
It's sensible to get more than one quote, and we'd never say otherwise. When you compare them, look past the bottom line at what's actually included:
- Is safe access and scaffolding included, or added later as an "extra"?
- Does it cover the flashing and flaunching, or only the pointing?
- Is it repointing, a rebuild, or both — and is that spelled out?
- Are they using the right mortar (lime on older/period stacks), and can they match your brick or stone?
- Are they insured, and how long have they been doing this kind of work?
A cheap quote that skips proper scaffolding, ignores the flashing or slaps cement on an old stack can cost you far more within a couple of winters. A clear quote that sets out the method, the access and the materials is worth more than a single low figure with no detail.
Key takeaways
- There's no fixed price for chimney repairs — access is often the biggest single cost, not the brickwork.
- Guide ranges in Ireland: repointing a stack around €600–€1,500; a full rebuild from about €1,500–€4,000+ per stack, plus scaffolding.
- Do all the chimney work in one visit while the access is up — it's cheaper than getting up there twice.
- Catching it early is always cheaper — water getting into the stack turns a small repair into an indoor damp problem.
- Compare what's included (scaffolding, flashing, mortar type), not just the headline number. A free site visit is the only reliable quote.
Frequently asked questions
How much does it cost to repoint a chimney in Ireland?
As a rough guide, repointing a chimney stack often falls between about €600 and €1,500, but access is the biggest single factor. A stack reached from a scaffold tower is far cheaper than one needing full scaffolding. The only reliable figure comes from a site visit, which we do for free.
How much does it cost to rebuild a chimney?
Taking a stack down and rebuilding it in matching brick or stone typically runs from around €1,500 to €4,000 or more per stack, depending on size, height, access and materials — plus scaffolding where it's needed.
Why is scaffolding such a big part of the cost?
A chimney is the highest, most exposed point of the house, so safe access often means erecting scaffolding — a real share of the total. It's why it usually makes sense to do all the chimney and nearby roof work in one visit while the access is up.
Can you stop damp on the chimney breast?
Usually yes. Damp inside almost always comes from failed pointing, cracked flaunching or worn flashing letting rain into the stack. We fix the source so the wall can dry out, rather than just covering the stain. See our chimney repairs page for what's involved.
Do you charge for a chimney quote?
No. The site visit and quote are free, with no obligation. Send us a photo of the stack or the damp inside and we'll tell you honestly what it needs before we come out.
