Chimney stack repairs in Port Glasgow
Damp on a chimney breast in a Port Glasgow home often starts at the top of the stack, where cracked flaunching or failed pointing lets rain in. Fixing the stack and capping unused flues usually stops it at the source.

How we usually approach chimney stack repairs
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
Partial or full rebuild
Where the lean is pronounced or the brickwork is badly decayed, the stack is taken down to sound masonry, often to roof level, and rebuilt plumb with new flashings and flaunching. Original bricks are cleaned and reused where possible to keep the appearance.
Best for: Badly leaning or decayed stacks
What happens during chimney stack repairs, step by step?
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.
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.
Repair, restrain or rebuild
The agreed work is carried out: repointing, new flaunching and pots, restraint, or taking the stack down and rebuilding it. Lead flashings where the stack meets the roof are checked and renewed if needed.
Rules for chimney stack repairs in Scotland
In Scotland, underpinning and other structural alterations generally need a building warrant from the council’s building standards service before work starts, and a completion certificate at the end; small like-for-like repairs often do not. There is no Party Wall Act in Scotland; shared walls are covered by title deeds and, for flats, the Tenements (Scotland) Act 2004.
Questions about chimney stack repairs in Port Glasgow
How much will chimney stack repairs cost in Port Glasgow?
Guide prices for chimney stack repairs in Port Glasgow start from about £475 per stack, including VAT, on Scotland rates. Your fixed written price follows photos or a survey and depends on the extent of the work and access.
Do you cover Port Glasgow?
We do. Port Glasgow and the surrounding area are covered, including nearby Greenock and Alexandria. A free initial assessment from your photos is the first step.
Is the ground in Renfrewshire and Inverclyde prone to subsidence?
Renfrewshire has glacial till and Clyde alluvium with coal workings recorded in parts, while Inverclyde's towns climb steep slopes above the Clyde with many retaining walls. 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 if a chimney breast below has been removed?
Where the breast has gone but the stack is still on the roof, how that stack is now held up is a structural question. Cracking in nearby ceilings or a dropped stack are warning signs. An independent chartered structural engineer should assess it before any repair, and we can arrange one.
