Chimney Repairs South Wales › Neath › Guide
On a Neath terrace or semi-detached pair, one chimney stack often sits across the dividing wall and serves both houses. That makes repair a shared matter. The brickwork is the same, but access, scaffold and agreement between neighbours need sorting first. Here is how we handle it.
How shared stacks work
Along older streets, the stack rises from the party wall and carries pots for both houses. Each side has its own flues, but the brickwork between them is one structure, and damage to one side usually affects the other. Because the stack stands on the ridge, it takes the full weight of the weather. When it fails, both houses can see damp, loose pots or a lean. Skewen, Cimla and Briton Ferry all have streets laid out this way, so we know the pattern well.
Who pays and who agrees
How the cost is split, and whether both owners want the work done at the same time, is for the owners to agree between you. We do not give legal advice on shared arrangements. What we can do is explain the work clearly to both households, so you each know what is needed and why. A written quotation covers the whole stack and you can talk it over together. Once the owners are agreed, we can book the work.
Scaffold and access
A shared stack usually needs scaffold or a tower, and sometimes access from next door's side. We agree with each household where it goes, how long it stays and how we keep the work tidy. Rear lanes in Neath can be narrow, so we plan deliveries and ladders carefully. We talk to neighbours about access ourselves, so you are not left to arrange it.
- Scaffold position agreed with both owners
- Access through or beside the neighbouring house if needed
- Pots, gardens and washing lines cleared beforehand
- Work planned around weather and rain
What the repair covers
We inspect the whole stack from the ground and loft, then repair or rebuild it as one job. Pots on both sides are re-bedded, flaunching renewed, and failed brick taken down and rebuilt in a matching mortar. If one side has an unused flue, we cap and vent it. Doing both sides at once avoids a half-finished stack that fails again on the neighbour's side. We also check the pointing and the capping on the shared ridge, so nothing is left to fail after the scaffold has gone.
If only one side wants the work
Sometimes only one owner wants to proceed. We can assess what can be done, but a shared stack is a single structure, so repairing half of it may not hold. We tell you honestly what is possible and what is not, and suggest you speak to your neighbour. Please do not go up to the stack yourself; call us for a proper look.

Common Questions
Do both neighbours have to agree before you start?
We need access, so yes, both households should be on board. Who pays and how the cost is split is for the owners to settle. We are happy to speak to your neighbour about the work and what is involved.
Can you repair just my half of a shared stack?
Sometimes, but it is a single structure and the two halves depend on each other. We assess first and tell you whether a one-sided repair will hold or whether the whole stack should be done together.
Will the scaffold go on next door's property?
It depends on the street. Where rear lanes are narrow or the stack sits on the party wall, we may need access from both sides. We agree this with both households before any scaffold goes up.
