Where a stack lets water in
A chimney stack takes the full force of Berkshire weather, sitting exposed above the roofline where wind and rain drive into aging mortar joints and cracked flaunching.
- Cracked mortar and crumbling bricksFrost and rain erode lime and cement mortar between chimney bricks. Once rainwater enters the joints, winter freezes push the bricks apart, causing internal damp along the breast inside houses in Thatcham and Newbury.
- Flaunching failure around chimney potsThe concrete flaunching at the top of the stack holds the chimney pots firm and sheds rainwater away. When it splits, water flows down the flue or into the core of the masonry.
- Damaged lead flashing at the roof junctionWhere the brickwork meets the roof tiles or slates, worn lead soakers and cover flashings allow run-off to slip underneath, rotting roof battens and dampening ceiling plaster below.
What happens on the day
We check the chimney from roof level to understand how far weathering or damp has penetrated the masonry.
- Visual check and assessmentWe inspect the brick courses, check the mortar joints for depth of erosion, examine the condition of the flaunching and test whether pots are loose in their beds.
- Access and safety setupWe arrange safe ladder or scaffold access to reach the stack without putting weight on adjoining roof tiles or slates.
- Cleaning back and repointingWe rake out perished mortar cleanly to a sound depth, clear dust and debris, and repoint using mortar suited to your property's age and brick type.
- Capping and clearingWe rebed the pots in fresh flaunching sloped to push water away from the stack, clearing away all chipped mortar and broken brick debris from the roof and gutters.

Chimney questions
How do I know if my chimney stack needs repointing?
Look for mortar sand collecting in your gutters, visible gaps between bricks, moss growing in joints or damp staining on ceilings around the chimney breast inside.
What is chimney flaunching?
Flaunching is the angled mortar or concrete bed at the top of a chimney stack. It holds the chimney pots in place and directs rainwater off the top of the brickwork.
Do you need scaffolding to repair a chimney?
Small repairs on accessible roof slopes can often be completed from specialised roof ladders. Taller stacks, steep pitches or major rebuilding work require scaffolding to work safely.
Can cracked chimney pots be replaced during repointing?
Yes. If a pot is fractured or missing, we can fit a replacement chimney pot and bed it into the fresh flaunching while carrying out the masonry work.
How does chimney damp travel inside the house?
Water penetrates porous or open mortar joints during prolonged rain. It then soaks downward through the brickwork core and shows as brown stains on interior plaster.
