Chimney stack repairs in Portadown
Damp on a chimney breast in a Portadown home often starts at the top of the stack, where cracked flaunching or failed pointing lets rain in. Fixing the stack and capping unused flues usually stops it at the source.

How we usually approach 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
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
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.
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.
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
- Cracked or missing flaunching around the top of the stack
- A stack visibly leaning when you look along the roof ridge
- Bits of brick, mortar or render landing in the garden or gutter

Questions about chimney stack repairs in Portadown
How much will chimney stack repairs cost in Portadown?
Guide prices for chimney stack repairs in Portadown start from about £440 per stack, including VAT, on Northern Ireland rates. Your fixed written price follows photos or a survey and depends on the extent of the work and access.
Do you cover Portadown?
We do. Portadown and the surrounding area are covered, including nearby Craigavon and Banbridge. A free initial assessment from your photos is the first step.
Is the ground in County Armagh prone to subsidence?
County Armagh has glacial drumlin till over older rock, with soft ground and peat near Lough Neagh. 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.
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.
