Chimney stack repairs in Gloucester
Before repairing a stack at a Gloucester 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.

How do local ground conditions affect chimney stack repairs in Gloucester?
Gloucester (GL1, GL2, GL4) has around 130,000 residents and sits in Gloucestershire. Nearby places we cover include Cheltenham (7 miles), Stroud (8 miles) and Tewkesbury (9 miles).
Parts of Gloucestershire have clay that can shrink near trees in dry spells. Parts of Gloucestershire lie on a former coalfield, so a coal mining search is worth checking if movement has no obvious cause.

How we usually approach chimney stack repairs
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
What happens during chimney stack repairs, step by step?
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.
What to look for before calling about chimney stack repairs
- Damp patches on the chimney breast inside, especially after rain
- Mortar washed out of joints, leaving bricks standing proud
- A stack visibly leaning when you look along the roof ridge

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.
Questions about chimney stack repairs in Gloucester
How much should I budget for chimney stack repairs in Gloucester?
Guide prices for chimney stack repairs in Gloucester 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 Gloucester?
We do. Gloucester and the surrounding area are covered, including nearby Cheltenham and Stroud. 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.
What if a chimney breast below has been removed?
Where the breast has gone but the stack is still on the roof, how that stack is now held up is a structural question. Cracking in nearby ceilings or a dropped stack are warning signs. An independent chartered structural engineer should assess it before any repair, and we can arrange one.
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.
