Skip to content Most roof leaks blamed on the slates actually start at the chimney. Water gets in through tired lead, crumbling mortar joints, or a cracked stack, then shows up somewhere else inside. We find where it is really getting in, then re-lead, repoint, or rebuild the stack and seal it for good.

Chimneys take the worst of the weather. They stand proud of the roof and catch the wind-driven rain, so they’re where leaks and damage tend to start. These are the warning signs.
Stain or musty smell around the chimney, often in bedroom. The water usually gets in up at roof and tracks down inside, the damp shows well below the leak.
Flashing is the lead seal where the chimney meets the roof, the most common cause of chimney leaks. Once cracks or pulls away from brickwork, rain runs straight in.
Gaps in the mortar joints, brick faces flaking off (spalling), or a stack that looks like it’s leaning against the sky. That’s where repointing, or a rebuild, comes in.
We find the leak first, then fix the cause. Sometimes that is the leadwork, sometimes the mortar, and now and then it is a slipped slate behind the stack, not the chimney at all. Each job can cover:
Unused chimneys get capped off properly and kept ventilated, so the stack stays dry instead of sweating inside. You get a written price in your hand before any work, with workmanship cover on the repair.
Most roof problems start small and quiet, then get expensive. If you have spotted any of these, it is worth getting them looked at before the next downpour.
We come out, get on the roof, and find exactly what is wrong.
You get a clear, itemised price. No call-out charge, no pressure.
Our own crew carries out the work, tidily and on the agreed date.
We show you what we did and stand over the work.
Most stacks need far less than a rebuild, and four checks at the survey tell us honestly which yours needs.
Shallow crumbling gets repointed and stack lives, Mortar soft deep into joints points toward rebuilding.
Few weathered faces get cut out and replaced. Bricks flaking and crumbling across the stack cannot be saved.
Stacks that have started leaning or cracking through the brickwork are safety call, and rebuilding the honest answer.
Cracked crown gets recast and loose pots rebedded. Neither one on its own ever means a full rebuild.
A few recent repairs around Dublin. Real jobs, real homes.
Re-leading the flashing is a small job. Repointing a whole stack or taking it down and rebuilding it is not; so an honest price needs a look at yours. What moves it most is whether it’s flashing, pointing, or a rebuild; how much lead and mortar work is involved.
The access, since a chimney almost always needs scaffolding. Use the calculator for a guide, then book a free inspection, and we’ll put a fixed price in writing. If the stack is past saving, we’ll tell you that rather than patch it.

No call-out charge, no obligation. We’ll tell you honestly whether it needs repairing or replacing.
Most often it’s failed lead flashing where the chimney meets the roof. Sometimes it’s a cracked crown, crumbling mortar, or a slipped slate or blocked gutter near the stack. The leak usually shows on the ceiling away from the chimney because the water tracks along the timber, so we find the real source first.
If the brickwork is sound, repointing and re-leading will do. If the stack is leaning, the brick is badly spalling, or the mortar has gone throughout, a partial or full rebuild is the safer fix. We’ll tell you which after the inspection.
It depends on whether it’s flashing, repointing or a rebuild, and on access, since a chimney usually needs scaffolding. Use our roof cost calculator for a guide, then book a free inspection and we’ll give you a written, fixed price.
Yes. We use lime mortar and brick matched to the original so the chimney keeps its character and breathes the way an older stack should. See our conservation roofing for period work.
