Is Wiltshire prone to ground movement?
With roughly 17,000 people, Devizes spans postcode districts SN10 in Wiltshire. We also take enquiries from nearby Calne (6 miles), Melksham (6 miles) and Chippenham (9 miles).
Wiltshire has a mix of ground, with clay in some places and firmer rock in others. Ground movement here is more often linked to soils, drains and trees than to mining. Typical buildings in Wiltshire: Stone cottages, railway terraces in Swindon, and large post-war and new-build estates.
Which repair method suits a home in Devizes?
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
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
What happens when we carry out chimney stack repairs in Devizes?
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.
Weatherproof and clear
Caps or cowls are fitted where agreed, the roof around the stack is checked for slipped tiles, and debris is cleared from gutters. You receive photos of the finished stack taken from the scaffold, since it is hard to see from the ground.
Signs you may need chimney stack repairs
- Bits of brick, mortar or render landing in the garden or gutter

Rules for chimney stack repairs in England
In England, underpinning and other work that alters or strengthens a wall or foundation is building work under the Building Regulations (Part A, structure), so building control approves and inspects it. Like-for-like repairs often are not, and we tell you which applies before a price is agreed. Work to a party wall, or excavation close to a neighbour’s foundations, can also need a notice under the Party Wall etc. Act 1996.

Does the ground around Devizes cause cracking?
Southern Wiltshire is chalk, while the north around Swindon, Chippenham and Trowbridge sits on Oxford and Kimmeridge Clays that are prone to seasonal movement near trees. Bath stone was mined underground around Corsham. Only an investigation can say why a particular building has moved.
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.
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.
