Repair options we may recommend

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 to expect when we carry out chimney stack repairs

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.
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.

Your chimney stack repairs questions

How much should I budget for chimney stack repairs in Helensburgh?

Guide prices for chimney stack repairs in Helensburgh 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.

Can you survey a property in Helensburgh?

Survey visits to Helensburgh are by arrangement because of travel and access. We can still give a free initial view from photos, and we tell you any travel cost before a visit is booked.

Why do houses in Argyll and Bute crack?

Argyll is hard rock with thin glacial soils and raised beaches along the coast; mainland towns such as Helensburgh and Oban sit on steep coastal slopes. Only an investigation can say why a particular building has moved.

Can a leaning stack be straightened?

Not by pushing it back, because the brickwork would crack. A slight lean on a sound stack can be restrained so it moves no further. A pronounced lean is fixed by taking the stack down to sound masonry and rebuilding it plumb.

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.
