Keep loose masonry and water outside
Above-roof defects checked
We assess mortar, masonry, pots, flaunching and the roof junction.
Roof covering protected
We plan access and stack work with the surrounding roof in mind.
Repair or removal clarified
We explain when a stack is serviceable and when removal may suit better.
Repair the exposed structure above your roof
A chimney stack takes the full force of rain, wind and frost. Missing mortar, loose bricks or stone, cracked flaunching and leaning masonry can let water in and create a risk of debris falling onto the roof or ground. We assess the above-roof structure, including its pots, joints, top finish and junction with the roof. Damp around a chimney breast may start at any of these points, so the visible indoor mark isn't enough to diagnose it. Our experience across chimneys and roofing helps us inspect the whole exposed area and choose work that suits the stack's actual condition.
From local masonry work to rebuilding
A serviceable stack may only need local masonry replacement, repointing or repair to its flaunching. Where deterioration or movement is more extensive, controlled rebuilding may be the sounder choice. We consider safe access, protect the surrounding roof covering and finish the repaired junction against the weather. If the stack is redundant or structurally unsuitable, removal may be considered instead of repeated repairs. For a chimney stack repair in Kendal, we explain why repair, rebuilding or removal best fits what we find.
Frequently asked questions
What are the signs of a failing chimney stack?
Open mortar joints, cracks, loose masonry, damaged flaunching, leaning sections and debris on the roof or ground all need attention. Internal damp near the chimney may also point to a stack or flashing defect, although inspection is needed to confirm the cause.
Can only part of a chimney stack be rebuilt?
A localised section may be rebuilt when the remaining stack is stable and sound enough to retain. We assess the extent of deterioration and how new masonry will connect with the existing structure before recommending a partial or wider rebuild.
When is chimney removal better than repair?
Removal may be considered where a stack is redundant, badly deteriorated or unsuitable to retain. The decision also depends on structural connections, flues and roof making good. We assess those points rather than treating demolition as a simple roof-level job.
