What should you know about the ground under Tyne and Wear?
Tyne and Wear lies on the Durham and Northumberland coalfield, with old shallow workings recorded beneath parts of Newcastle, Gateshead and Sunderland, mostly under a cover of glacial clay.
Historic coal workings are recorded beneath parts of Tyne and Wear, and a coal mining search is worth checking where movement is unexplained. Typical buildings in Tyne and Wear: Tyneside flats and terraces, Victorian villas, inter-war council estates and post-war semis.

Methods for chimney stack repairs
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
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
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
- Bits of brick, mortar or render landing in the garden or gutter
- Cracked or missing flaunching around the top of the stack
- Mortar washed out of joints, leaving bricks standing proud
Do you need approval 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
Does the ground around Newcastle upon Tyne cause cracking?
Tyne and Wear lies on the Durham and Northumberland coalfield, with old shallow workings recorded beneath parts of Newcastle, Gateshead and Sunderland, mostly under a cover of glacial clay. Historic coal workings are recorded beneath parts of Tyne and Wear, and a coal mining search is worth checking where movement is unexplained. Only an investigation on site can say why a particular building has moved.
How much will chimney stack repairs cost in Tyne and Wear?
On North East rates, chimney stack repairs starts from about £460 per stack, including VAT. The written price depends on the extent of the damage, access and whether an engineer or building control is needed.
Why is my chimney stack leaning?
Most leaning stacks are caused by sulphate attack, where chemicals from old flue gases make the mortar expand more on the wetter side, so the stack bends away from the weather. Frost damage and failed pointing can make it worse. A recently leaning stack can also signal problems below.
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.
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.
