Chimney Stacks in Cardiff
A chimney is the most exposed masonry on any building — wet on all four sides, with no roof over it and nothing sheltering it from driven rain off the Channel. On a roof sharing its valleys and its stacks the stacks are frequently the oldest and least maintained part of the structure, and on terraced property they are often shared.
What This Covers
- Failed mortar joints
- Loose masonry
- Weathered chimney stacks
- Water ingress connected with the affected detail
- Localised weathering or damage requiring repair
Why Stacks Erode Here
With wind enough to find a slipped slate, a stack is wetted and dried more often than any wall on the building, and every cycle takes a little more mortar. Add frost into saturated joints and on these bay-fronted slate terraces the pointing goes from sound to open in a few seasons once it has started.
Access to the Stack
Nothing about a chimney can be done from a ladder, so with access tight for scaffold a stack job is a scaffold job and the scaffold is a real part of the price. Because a defect here is often shared with next door, anything else needing doing at high level is worth doing while it is up.
Repointing, Flaunching and Rebuilding
Repointing means raking the old mortar out properly and filling with a mix suited to the brick you actually have on a roof sharing its valleys and its stacks. On these bay-fronted slate terraces that generally means something softer than modern cement, which is harder than the brick and pushes the face off it. The flaunching, the mortar weathering around the pots, is checked at the same time, because with driven rain off the Channel a cracked flaunching is letting water straight into the stack.

Chimney Repointing & Repairs in Cardiff — Common Questions
What are common signs that I may need chimney repointing & repairs in Cardiff?
A chimney is the most exposed masonry on any building — wet on all four sides, with no roof over it and nothing sheltering it from wind enough to find a slipped slate. Add frost into saturated joints and on a roof sharing its valleys and its stacks the pointing goes from sound to open in a few seasons once it has started.
Can a small defect cause an internal leak?
Yes. The kind of defect behind chimney repointing & repairs lets water into the structure on these bay-fronted slate terraces, and it can travel a long way before it shows on a ceiling. That is why the source of a chimney repointing & repairs problem is traced rather than guessed at from the mark inside.
Will the whole roof need replacing?
Usually not. Chimney repointing & repairs is repair work, and on a roof sharing its valleys and its stacks the covering around the defect is generally sound — whether a repair is the right answer depends on how far the deterioration has gone beyond the part you can see.
Can you inspect the problem before recommending work?
Yes, always. Given a defect here is often shared with next door, a chimney repointing & repairs job on these bay-fronted slate terraces is looked at before anything is recommended, and you get told what was actually found rather than a figure guessed from the pavement.
Do you cover other roof repairs in Cardiff?

Do you cover Cardiff and the surrounding area?
Yes — chimney repointing & repairs throughout Cardiff and the places around it, including Roath, Canton, Cathays, Splott and Llanishen.
What does a repair like this cost?
Two things set the figure for chimney repointing & repairs: how far the defect has actually gone, which needs somebody to look at it, and the access. With access here restricted by controlled parking and narrow frontages, that second one moves the price of chimney repointing & repairs more than the materials do, and it is why a figure over the phone is a guess.
Can you look at other things while you are there?
Yes, and it is worth it — given a defect here is often shared with next door, safe access to the roof is most of what a visit costs, so anything else wanting attention is far cheaper dealt with on the same day as the chimney repointing & repairs.
