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

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.
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.

Rules 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.

Questions about chimney stack repairs in Armagh

How much should I budget for chimney stack repairs in Armagh?

Guide prices for chimney stack repairs in Armagh 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.

Can you survey a property in Armagh?

Yes. We take enquiries from across Armagh, including BT61, and from nearby places such as Portadown and Dungannon. Send photos for a free initial view and we will tell you what happens next.

Why do houses in County Armagh crack?

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 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.

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.
