Chimney Repairs South Wales › St Mellons › Guide
Plenty of St Mellons homes have a small chimney that has never been used and does nothing except collect rain. Taking it down or making it shorter is often possible. The answer depends on what holds the stack up, how it sits on the roof and what the house needs afterwards.
Removal and reduction are different jobs
Removal means taking the stack down to below the roof line and making the roof good. Reduction means lowering it, leaving a shorter stack with a new cap. Reduction suits a stack that is still needed for a flue or shared with next door, while removal suits one that serves nothing at all. Which one is right depends on whether any flue is still in use, and on what sits underneath in the loft and the room below.
What we check before agreeing to anything
We assess first. A chimney breast can carry floor or roof weight, and taking out the stack above without thinking about that can cause trouble later. We look at the stack from a safe position, then at the loft and the breast in the room below. Structural support, Building Regulations or planning checks may apply, and we advise on these before work starts.
- Whether the stack is shared with a neighbouring house
- Whether the breast below supports anything above it
- Condition of the brickwork and mortar in the stack
- How the roof timbers are arranged around the chimney
- Whether any flue is still connected to an appliance
What the work involves
The stack is taken down by hand, course by course, with the roof below protected from falling debris. Scaffold or a tower is set up first, because a loose stack is not something to lean a ladder against. Once the stack is gone, the roof is made good with matching tiles, new timbers where needed and a watertight finish. If the flue stays open below, it is vented properly so the breast does not trap damp.
Shared stacks and neighbours
Many estate houses share a stack with the house next door. In that case both owners need to agree before anything changes, and who pays and how it is arranged is for the owners to settle between themselves. We do not give legal advice on that. What we can do is speak to the neighbour about access and scaffold, and explain exactly what will happen to their side of the roof.
What to ask before you book
Ask what will be done to the roof once the stack is gone, how the flue will be dealt with, and who deals with any checks that apply. Ask whether the breast below is being touched, because removing that is a separate structural job. A clear written quotation that describes each stage is the best protection against surprises.
- What will fill the gap in the roof
- How the open flue will be ventilated or sealed
- Whether any checks or permissions are needed
- Who is responsible for clearing the debris

Common Questions
Do I need permission to remove a chimney stack?
It depends. Some work may need Building Regulations or planning checks, especially where the breast below carries weight or the house is in a protected area. We assess the chimney first and advise on what applies before any work begins.
Can I remove just the part above the roof?
Yes, in many cases. Taking the stack down to roof level and covering the gap is a common job. The flue below then needs to be ventilated or sealed correctly, and the breast must be left sound, which we check when we inspect.
Will taking the stack down stop my damp problem?
If the stack was letting water in, removing it and making the roof good usually deals with that source. Damp can have other causes, so we check the loft and breast to be sure the stack really was the problem.
