Failing Pointing and Mortar
Weathered mortar joints let rain soak into the stack, which can lead to damp patches in the chimney breast and the rooms below. We rake out and repoint the affected areas with a mortar that matches the existing brickwork.


Common Problems
Weathered mortar joints let rain soak into the stack, which can lead to damp patches in the chimney breast and the rooms below. We rake out and repoint the affected areas with a mortar that matches the existing brickwork.
Where the stack meets the roof, lead or cement flashings can lift, crack or fail. This is one of the most common causes of leaks around a chimney. We assess each junction and repair or replace the flashing that needs it.
Chimney pots can crack, slip or come loose in strong winds. We check the pots, their bedding and the stack they sit on, then re-bed, repair or replace them so the flue stays safe and weatherproof.
The flaunching at the top of the stack sheds water away from the pots. When it cracks, water runs into the brickwork. We repair or renew the flaunching and capping so the top of the stack stays sound.
Our Work
A chimney stack takes the full force of the weather, so small faults in the pointing or flashing can quickly allow water into the building. Repairing the source of the problem, rather than covering the stain, keeps the stack sound and protects the rooms below.
We match mortar to the existing brickwork and keep the character of the property in mind. For a broader look at our work, see our chimney repair service.

Not usually. We inspect the stack and repoint only the joints that are failing. Matching the mortar to the existing brickwork is important, so we avoid repointing sound areas unless it is needed for a lasting repair.
