Why Dressing the Lead Lip Flat to the Brickwork Matters

A flush, void-free fit is essential for lasting lead flashing on any chimney stack. Once dressed flat, we apply a lead sealant that needs full, even contact with the brickwork to bond properly — any gap or high spot leaves the sealant bridging a void instead of adhering to solid brick, and that’s where leaks start. Getting this right is what separates chimney flashing that lasts for decades from one that needs repairing within a few years.
