Chimney flashings
Front apron, side soakers and stepped cover flashings chased into the mortar joint and wedged, not smeared over the brick. The single most common leadwork job we do.

Lead is where most roofs actually leak. Get the flashings right and the rest of the roof looks after itself; get them wrong — or fill the joint with mortar and hope — and you'll be chasing the same damp patch for years.
Leadwork we carry out
Front apron, side soakers and stepped cover flashings chased into the mortar joint and wedged, not smeared over the brick. The single most common leadwork job we do.
Where an extension roof meets the house wall. Done properly in short bays so the lead can move without splitting.
Traditional lead-lined valleys on period Braintree and Bocking properties, replaced like-for-like at the correct code and bay length.
Cheeks, tops and aprons — often the fiddliest lead on a house and the first place a bodged repair shows.
Lead-lined box and parapet gutters on older buildings, with proper drips and expansion joints.
Cement fillets always crack. We cut them out and replace with code-graded lead — the fix that stops the call-backs.

Code 4 and code 5 lead, correctly wedged and pointed, including removal of the old flashing or fillet.

Doing it right
Local knowledge
Older housing means more chimneys, more valleys and more lead.
Multiple chimney stacks and lead-lined valleys, frequently with decades of mortar-fillet repairs to cut out first.
Single stack, simple flashings — a quick job that stops a persistent chimney-breast damp patch.
Where new work meets old wall. Done in bays, with the correct upstand height rather than the minimum that fits.
Traditional detailing and materials, matched to what's already there and to any conservation requirements.
