Which repair method suits a home in Swansea?
Stack restraint or strapping
A stack that has leaned slightly but is otherwise sound can be restrained with stainless straps or ties fixed back to the roof structure or the gable. This stops further movement without taking the stack down, and is often combined with repointing.
Best for: Slightly leaning stacks with sound brickwork
Flaunching and pot resetting
Old cracked flaunching is broken out, pots are lifted and reset or replaced, and new flaunching is formed to a fall so water runs off. Unused flues can be capped with ventilated caps, which keeps rain out while letting the flue breathe.
Best for: Loose pots and cracked mortar at the top of the stack
What happens when we carry out chimney stack repairs in Swansea?
Look from the ground
Photos from the street and garden, ideally with a zoom, show us the lean, the pots, the flaunching and the state of the pointing. Damp patches inside are worth photographing too, as they help trace the route water is taking.
Check what is below
We ask whether any chimney breasts have been removed, and check the loft and rooms below for cracking. If a breast has gone without proper support, we recommend an independent chartered structural engineer before any stack work.
Scaffold to the stack
Safe access is set up with a working platform around the stack. On terraces we may need to agree access over a neighbour’s roof, and a council licence is arranged where the scaffold stands on the pavement.
Rules for chimney stack repairs in Wales
In Wales, the Welsh version of the Building Regulations applies. Underpinning and other work that alters or strengthens the structure needs building control approval and inspection; like-for-like repairs often do not. The Party Wall etc. Act 1996 applies to work on party walls and excavation close to a neighbour’s foundations.
Chimney stack repairs in Swansea: questions and answers
How much will chimney stack repairs cost in Swansea?
Guide prices for chimney stack repairs in Swansea start from about £460 per stack, including VAT, on Wales rates. Your fixed written price follows photos or a survey and depends on the extent of the work and access.
Do you cover Swansea?
Yes, Swansea is covered, along with postcode districts SA1, SA2, SA5. We also cover nearby Clydach and Gorseinon.
Is the ground in West Glamorgan prone to subsidence?
Swansea and Neath Port Talbot lie on the South Wales coalfield, with historic workings, tips and steep valley sides, and softer estuarine ground around the docks. Only an investigation can say why a particular building has moved.
Should I remove my chimney stack instead of repairing it?
It depends on whether you use the flue, the stack’s condition and how it relates to the house next door. Taking a stack down below the roofline changes the structure and the roof, and on a terrace it can affect your neighbour. We can price both options.
What is chimney flaunching?
Flaunching is the sloped bed of mortar on top of a chimney stack that holds the pots in place and throws rainwater off. When it cracks, water gets into the stack and pots can work loose. Renewing it is one of the most common stack repairs.
