Which repair method suits a home in Johnstone?
Repointing and brick repairs
Eroded joints are raked out and repointed in a mortar suited to the brick, often a lime-based mix on older stacks. Spalled or cracked bricks are cut out and replaced with matched reclaimed or new bricks. On many stacks this, with new flaunching, is all that is needed.
Best for: Upright stacks with weathered joints and some damaged bricks
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 Johnstone?
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.
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.
Chimney stack repairs in Johnstone: questions and answers
What is the price of chimney stack repairs in Johnstone?
Guide prices for chimney stack repairs in Johnstone 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.

Does the ground around Johnstone cause cracking?
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.
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.
Why is my chimney stack leaning?
Most leaning stacks are caused by sulphate attack, where chemicals from old flue gases make the mortar expand more on the wetter side, so the stack bends away from the weather. Frost damage and failed pointing can make it worse. A recently leaning stack can also signal problems below.
