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?
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.
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.
What to look for before calling about chimney stack repairs
- Chimney pots that are loose, tilted or cracked at the base
- Bits of brick, mortar or render landing in the garden or gutter
- 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 Spennymoor
How much will chimney stack repairs cost in Spennymoor?
Guide prices for chimney stack repairs in Spennymoor start from about £460 per stack, including VAT, on North East rates. Your fixed written price follows photos or a survey and depends on the extent of the work and access.
Do you cover Spennymoor?
Yes, Spennymoor is covered, along with postcode districts DL16. We also cover nearby Bishop Auckland and Durham.
Is the ground in County Durham prone to subsidence?
Much of County Durham sits on the Durham Coalfield, worked for centuries, often under a cover of glacial clay. Many former pit villages have recorded mine workings, and coal mining searches are standard for property here. Only an investigation can say why a particular building has moved.
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.
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.
