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

What should you know about the ground under Saltash?
Saltash is in Cornwall and takes in postcode districts PL12. About 16,000 people live there. Neighbouring towns we cover: Plymouth (4 miles), Bodmin (22 miles) and St Austell (25 miles).
Clay shrinkage is less of a concern in Cornwall, so other causes such as drains, poor footings or older walls are checked first. Old metal-mine shafts and workings are recorded in places, so mining searches are routine for some properties. Across Cornwall, most homes are granite and slate-stone cottages, cob buildings, Victorian terraces and post-war estates.
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.
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.
What to look for before calling about chimney stack repairs
- Mortar washed out of joints, leaving bricks standing proud
- Chimney pots that are loose, tilted or cracked at the base
- Damp patches on the chimney breast inside, especially after rain

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
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
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 Saltash
How much should I budget for chimney stack repairs in Saltash?
Guide prices for chimney stack repairs in Saltash 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 Saltash?
Yes, Saltash is covered, along with postcode districts PL12. We also cover nearby Plymouth and Bodmin.
Why do houses in Cornwall crack?
Cornwall is mostly granite and slate with little shrinkable clay, so clay subsidence is less common than in the south-east. Historic tin and copper mining has left shafts and workings in places such as Camborne and Redruth, and mining searches are routine there. 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.
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.
