Tyrone has glacial till over varied rock, with a small historic coalfield around Coalisland near Dungannon.
Parts of County Tyrone lie on a former coalfield, so a coal mining search is worth checking if movement has no obvious cause. What you mostly find across County Tyrone: market-town terraces, rural houses and post-war estates.

Which repair method suits a home in County Tyrone?
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
Stack restraint or strapping
A stack that has leaned slightly but is otherwise sound can be restrained with stainless straps or ties fixed back to the roof structure or the gable. This stops further movement without taking the stack down, and is often combined with repointing.
Best for: Slightly leaning stacks with sound brickwork
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 when we carry out chimney stack repairs in County Tyrone?
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.
Do you need approval for chimney stack repairs in Northern Ireland?
In Northern Ireland, the Building Regulations (Northern Ireland) 2012 apply and the council’s building control service approves structural work such as underpinning; minor like-for-like repairs usually need no approval. The Party Wall Act does not apply in Northern Ireland, so work to shared walls depends on deeds and agreement with neighbours.

Chimney stack repairs in County Tyrone: questions and answers
Why do houses in County Tyrone crack?
Tyrone has glacial till over varied rock, with a small historic coalfield around Coalisland near Dungannon. Parts of County Tyrone lie on a former coalfield, so a coal mining search is worth checking if movement has no obvious cause. Only an investigation on site can say why a particular building has moved.
How much will chimney stack repairs cost in County Tyrone?
On Northern Ireland rates, chimney stack repairs starts from about £440 per stack, including VAT. The written price depends on the extent of the damage, access and whether an engineer or building control is needed.
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.
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.
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.
