Make every part of the junction work
Masonry checked first
We assess bricks or stone before treating failed joints alone.
Lead details traced
We inspect flashing, chases and the route water takes onto the roof.
Roof covering included
We check adjacent slates or tiles for defects that could keep leaking.
Separate mortar, masonry and flashing defects
Weathered chimney joints, damaged masonry and failed leadwork can all cause damp around the same part of a property. We attend homes in Grasmere to inspect the stack and exposed roof junction directly, rather than choosing a repair from the position of an indoor stain. Our formal bricklaying training supports careful repointing, while wider roofing experience helps us assess flashing and nearby coverings. This matters because fresh mortar won't seal split lead, and sound flashing can't make loose masonry stable.
Build a repair from compatible details
Where repointing is suitable, unsound mortar is removed and compatible replacement material installed with an appropriate joint finish. Lead repairs must direct water onto the roof covering while allowing normal movement. Slates, tiles, chases and flaunching are checked for related defects so the repaired area works as a complete junction. For work in Grasmere, send photographs of the chimney, roof and internal staining, plus access information. We then inspect the property and match the scope to the condition found.
Frequently asked questions
Will repointing stop damp around my chimney?
It may when water is entering through failed joints and the masonry is otherwise sound. Similar damp can come from leadwork, flaunching or roof coverings, so we inspect those details before treating mortar as the only cause.
Can leadwork and repointing be repaired together?
Yes, where both contribute to the defect or are failing within the same roof junction. Coordinating the work helps ensure renewed joints, flashing and adjoining roof materials direct water away as intended.
Why does chimney mortar fail faster than wall mortar?
The stack is highly exposed to rain, wind and frost from several sides. Once joints open, retained moisture can speed deterioration. Mortar choice, preparation, joint finish and curing conditions all influence the durability of repair work.
