Chimney Repairs South Wales › Tonypandy › Guide
Walk along almost any street of late 1800s terraces in Tonypandy and you will see chimney stacks sitting astride the party wall, serving the houses on both sides. That shared ownership changes how a repair is organised, though not how the brickwork is rebuilt. This guide explains what happens from the first look to the finished stack.
What makes a shared stack different
A shared stack carries the flues of two, sometimes four, houses in one column of brick. The weight sits on the party wall below, so a failing stack is every neighbour's concern, not just the owner of the house where the damp shows up. Repairs to one side can disturb the other, which is why we look at the whole stack and not only the half you can see from your own garden or loft hatch. Older flues also tend to be lined only with lime mortar.
What we check before any work
We start from the ground, with a close look at the stack for leaning, open joints, missing brick and cracked pots. Inside, we look at the chimney breast and the loft for damp staining and any loose debris that has fallen down the flue. Then we go up to examine the brickwork and the mortar crown directly, and tell you what we find in plain terms, with a free, no-obligation quotation for the repair.
- Lean or bulge visible from the street
- Open joints and soft, crumbling mortar around the brick
- Cracked, loose or missing pots on the top
- Damp patches on the breast or party wall in the loft
How the repair is carried out
Where the damage is limited to the top few courses, we take those off and rebuild them, then renew the flaunching and bed the pots securely. If the brick below is sound, there is no need to take the whole stack down. Where the stack is leaning or broken deeper down, it is taken down to solid masonry and rebuilt with matching brick, so both houses end up with the same finished stack. Everything removed is lowered safely to the ground.
Neighbours, access and who pays
We will speak to your neighbours about access, scaffold and timing, because the work usually needs to be coordinated across both roofs. Who pays and how the cost is shared is for the owners to agree between themselves, and we cannot give legal advice on it. What we can do is give a clear description of the work and a single quotation, so everyone is agreeing to the same thing.
Questions to ask before you agree
Ask what the quotation covers, whether scaffold is included, and what happens if more damage is found once the top courses are off. A sensible firm explains these points before starting, not halfway through. If a stack is being reduced or removed, ask how support will be dealt with and whether Building Regulations or planning checks apply. We advise on that before any work begins. Written details help everyone.

Common Questions
Do both neighbours have to agree before a shared stack is repaired?
It helps a great deal, as the work affects both roofs and needs access from both sides. Agreement and cost-sharing are for the owners to settle between themselves. We are happy to talk to neighbours about access and explain the work.
Can I just have my half of the stack repaired?
Usually not in a sensible way. The brickwork is one column, so repairing one half and leaving the other tends to leave a weak point. We assess the whole stack and explain what is practical before quoting. It also saves paying twice for scaffold.
What can I check from inside without going on the roof?
From the ground and the loft you can look for damp stains, flaking plaster or debris in the fireplace. Please never climb onto the roof or stack yourself. Call us and we will arrange a proper look.
