Often, yes. With so many post-war houses in Cwmbran now heated without a fireplace, redundant stacks are a regular request. But a chimney is part of the structure, and it sometimes holds up more than it appears to. We always assess before we agree to take anything down, and we advise on the checks before work starts.

Removal and reduction are different jobs

Reduction means shortening the stack, usually to just above the roof, and finishing it neatly. Full removal means taking the chimney down through the roof space, sometimes right down to the chimney breast inside the rooms. Which is sensible depends on how the roof is built, how the stack sits against it and what you want the house to look like from the street. We explain both options in plain terms, so you can choose with the facts in front of you.

What we check before agreeing

We look at the stack from the ground and the loft first, then plan a closer inspection from scaffold. The goal is to understand what the brickwork is carrying before anyone lifts a brick, because a chimney that looks redundant can still be doing structural work in the roof or the floors.

  • How the stack sits on the roof and where it meets the ridge or gable.
  • Whether the chimney breast supports floors, ceilings or the roof timbers above.
  • The condition of the brickwork, which affects how safely it can come down.
  • Whether a neighbouring house shares the stack or flue.

Shared stacks on terraces and semis

A lot of Cwmbran stacks sit across two houses, with a flue for each side. Taking one side away without care can leave the other unsupported or open to the weather. We talk to neighbours about access and timing, but who pays and how the work is agreed is for the two owners to settle between themselves. We cannot give legal advice on it.

Regulations and support

Taking out a chimney breast, or part of one, can need structural support to be put in, and Building Regulations or planning checks may apply depending on the house. We tell you what we think is needed before the work starts, so nothing is a surprise on the day. Where support is needed, that has to be right before anything comes out.

How the work is done and what to ask

The stack is taken down course by course from scaffold, and the roof is made good with matching tiles or slates and a weathertight finish. Ask whoever quotes for you how the opening will be closed, how debris will be cleared and what happens to the flue below the roofline.

Ask too about ventilation, because a flue that is closed off with no air movement can cause damp in the breast below. A good quote also says who clears the debris, who arranges scaffold and what finish the roof will have where the stack used to stand.

  • Will the stack be reduced or fully removed?
  • What happens to the flue and chimney breast below the roof?
  • Is any structural support or Building Regulations check needed?
  • How will the roof be made good afterwards?

Should an Unused Chimney Be Capped or Ventilated in Cwmbran?Plenty of Cwmbran houses have a fireplace that was blocked up when the heating changed. Sealing a flue completely can cause its own damp, so here is how capping and ventilation work together.
Why Is There a Damp Patch by the Chimney Breast in Cwmbran?A brown stain or peeling paint beside a chimney breast is a common complaint in Cwmbran houses. The cause is often at the top of the stack, not in the room where you see it.
Can an Old Chimney Be Used for a Stove in Cwmbran?Cwmbran's post-war houses often have a chimney that has stood unused for decades. Some are worth bringing back for a stove. Here is what decides it, and what falls to us and what does not.

Common Questions

Can I take the stack down myself to save money?

No. Working on a chimney stack at height is dangerous, and a stack can be heavier and less stable than it looks. Look from the ground or the loft hatch, and call us for a proper look and an honest assessment.

Will removing the stack leave a hole in the roof?

Not when it is done properly. The opening is closed with roof timbers and finished to match the surrounding tiles or slates, so the roof is weathertight again. We explain how this will be done before we begin.

Do I need to tell my neighbour?

If the stack is shared, yes, and we speak to them about access and timing. Any agreement about cost or responsibility is for the owners to settle between themselves, as we cannot give legal advice on it.
