Lead Flashing Replacement
Lead is our specialism. Most chimney and abutment leaks are failed flashings — we strip, dress and re-fit new Code 4/5 lead the way it should be done.
- Code 4 & Code 5 milled lead
- Soakers, step flashings & aprons
- Valleys, gulleys & cover flashings
- Lead-welded box gutters & dormers
- Patination oil finish
- 100-year+ life when laid right
Why lead fails (and why most replacements fail again)
Original lead doesn't fail — it lasts 80–100 years. What fails is mortar fillets and cement 'flashings' that builders use as a shortcut. When we replace, we do the proper job: lead chased into the brickwork, wedged, pointed, and patinated.
Why thickness (Code) matters
Code 3 lead is too thin for anything except small soakers and won't last on exposed flashings. We use Code 4 for most domestic work, Code 5 on chimneys, valleys and anywhere the wind catches.
FAQs
Why is lead so expensive?+
Material cost — milled lead is a significant raw-material item. But it's a once-in-80-years job when done properly, so the lifetime cost is actually low.
Can you weld lead on site?+
Yes — full lead welding for box gutters, dormers and complex junctions. It's how a proper lead detail should be made, not folded and bedded in mortar.
