Chimney stack repairs in Cirencester
Before repairing a stack at a Cirencester property, we ask what lies beneath it. If a chimney breast has been removed inside, the support for the stack above needs checking by an engineer before any work on the roof.

Methods for chimney stack repairs
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
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
From first photo to finished repair
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.
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.
Symptoms that point to chimney stack repairs
- Mortar washed out of joints, leaving bricks standing proud
- Damp patches on the chimney breast inside, especially after rain
- 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.
Frequently asked questions
How much should I budget for chimney stack repairs in Cirencester?
Guide prices for chimney stack repairs in Cirencester 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 Cirencester?
We do. Cirencester and the surrounding area are covered, including nearby Stroud and Cheltenham. A free initial assessment from your photos is the first step.
Why do houses in Gloucestershire crack?
The Severn vale around Gloucester, Cheltenham and Tewkesbury is Lias and Mercia Mudstone clay, the Cotswolds are limestone, and the Forest of Dean has a historic coalfield. Parts of South Gloucestershire around Kingswood also lie on old Coal Measures. 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.
Is a leaning chimney dangerous?
A leaning chimney can become dangerous, because stacks are heavy and stand high above the roof. A slight, long-standing lean may be stable for now, but a lean that is worsening, or loose bricks and pots, should be looked at quickly. Keep people away from below if anything looks loose.
