Chimney stack repairs in Exeter
On older houses around Exeter, many stacks lean slightly away from the prevailing weather. That is usually sulphate attack in the mortar, and the repair depends on how far the stack has moved and how sound the brickwork still is.

How do local ground conditions affect chimney stack repairs in Exeter?
With roughly 130,000 people, Exeter spans postcode districts EX1, EX2, EX3, EX4 in Devon. Neighbouring towns we cover: Exmouth (9 miles), Tiverton (12 miles) and Newton Abbot (14 miles).
Shrinkable clay is less common in Devon than in south-east England. Old metal-mine shafts and workings are recorded in places, so mining searches are routine for some properties. Across Devon, most homes are cob and stone cottages, Victorian terraces in Exeter, Plymouth and Torbay, and post-war estates.
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.
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.
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
- Chimney pots that are loose, tilted or cracked at the base
- Damp patches on the chimney breast inside, especially after rain
- Mortar washed out of joints, leaving bricks standing proud

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
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
What is the price of chimney stack repairs in Exeter?
Guide prices for chimney stack repairs in Exeter 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.
Do you carry out chimney stack repairs in Exeter?
Yes. We take enquiries from across Exeter, including EX1, EX2, EX3, EX4, and from nearby places such as Exmouth and Tiverton. Send photos for a free initial view and we will tell you what happens next.
Does the ground around Exeter cause cracking?
Devon's ground is mostly older mudstones, sandstones and granite, so shrinkable-clay subsidence is less widespread than further east. Older solid-walled and cob buildings, steep sites and retaining walls are the more common structural concerns. Only an investigation can say why a particular building has moved.
Do I need scaffolding for chimney repairs?
In almost all cases, yes. Safe work on a stack needs a stable platform at stack height, which usually means scaffold. Ladders and roof ladders do not give a safe place to repoint, lift pots or rebuild brickwork.
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.
