Lead flashing replacement and step-flashing make-good around chimney stacks. Common London Victorian-terrace leak source.
What we replace, end to end
Old lead flashing removed. Brickwork raked out and re-pointed where needed. New Code 4 or Code 5 lead flashing dressed to the chimney and roof. Step-flashing into the brick mortar joints. Lead sealant applied at the wall-to-lead joint. Photograph record of the completed work. If water is already coming through the ceiling, our roof leak emergency team can make the area safe first.
