Chimney Stacks in Caerphilly

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 exposure that changes with height. On the covering on the upper estates 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 on the mountain-side streets, 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 slate below and concrete tile above 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 steep above the town centre a stack job is a scaffold job and the scaffold is a real part of the price. Because exposure changes end to end on the same street, 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 the covering on the upper estates. On slate below and concrete tile above 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 exposure that changes with height a cracked flaunching is letting water straight into the stack.

Chimney Repointing & Repairs in Caerphilly — Common Questions

What are common signs that I may need chimney repointing & repairs in Caerphilly?

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 on the mountain-side streets. Add frost into saturated joints and on the covering on the upper estates 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 slate below and concrete tile above, 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 the covering on the upper estates 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 exposure changes end to end on the same street, a chimney repointing & repairs job on slate below and concrete tile above 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 Caerphilly?

Yes — chimney repointing & repairs is one of twenty-five roof repairs we carry out on the covering on the upper estates, and across the surrounding area including Bedwas, Llanbradach, Abertridwr, Senghenydd and Nelson.

Do you cover Caerphilly and the surrounding area?

Yes — chimney repointing & repairs throughout Caerphilly and the places around it, including Bedwas, Llanbradach, Abertridwr, Senghenydd and Nelson.

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 sharply different from one end of a street to the other, 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 exposure changes end to end on the same street, 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.
