Why does the ground in Wiltshire matter for chimney stack repairs?
Swindon, Wiltshire: about 200,000 residents across postcode districts SN1, SN2, SN3. We also take enquiries from nearby Calne (13 miles), Cirencester (14 miles) and Carterton (16 miles).
Clay soils are found in parts of Wiltshire. Ground movement here is more often linked to soils, drains and trees than to mining. Across Wiltshire, most homes are stone cottages, railway terraces in Swindon, and large post-war and new-build estates.
What to expect when we carry out chimney stack repairs
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.
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.

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
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
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.
Your chimney stack repairs questions
How much should I budget for chimney stack repairs in Swindon?
Guide prices for chimney stack repairs in Swindon start from about £515 per stack, including VAT, on South West 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 Swindon?
We do. Swindon and the surrounding area are covered, including nearby Calne and Cirencester. A free initial assessment from your photos is the first step.
Why do houses in Wiltshire crack?
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.
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.
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.
