A small junction can cause a big problem
Chimneys interrupt the roof covering and create several possible routes for water. Deteriorated mortar, defective flashing or damaged details at the top of the stack can each need a different solution. We assess the visible condition and surrounding roof before proposing the work.
Pointing and masonry repairs
Weathered mortar joints can allow moisture into the stack. Where appropriate, defective joints can be prepared and repointed using a suitable material for the existing brickwork. Loose or damaged masonry may need additional work. The extent of repair and the access required are explained after inspection.
Lead flashing and weathering details
Stepped flashing, back gutters and the junction with the roof covering need to shed water correctly. A patch over the visible surface may not resolve a poorly formed junction beneath it. We discuss repair or renewal according to the condition of the lead and adjacent roof, aiming for a considered, durable detail.
Safe access comes first
Chimney work is often at the highest part of a property. Scaffolding or another appropriate access arrangement may be required, even where the visible repair is small. Send ground-level photographs and tell us about rear access or adjoining properties when requesting a quotation. Work involving an active flue may also need input from the relevant specialist.
