Chimney & Abutment Lead Flashing — Boldon
Failed flashing shows up as a chimney-breast stain or a slow drip at an extension abutment — usually two or three winters after the last "quick fix". Proper Code 4 dressed into a chased joint and pointed with sand:cement doesn't come back for decades. We're regularly on roofs close to the A19, through West Boldon and East Boldon.
- Code 4 or Code 5 lead as the location demands — no thin turn-up stuff
- Chased into a fresh mortar joint, not silicone-glued to the render
- Stepped, soaker and back-gutter details all dressed by hand
- Sand:cement pointing finish, not mastic
- Old lead recycled and credited off the invoice where the weight justifies it
- Patination oil applied to prevent white-carbonate staining on new lead
Code 4 vs Code 5 vs Code 6

Lead flashing replacement in Boldon — FAQs
Can you just point the mortar rather than re-lead?+
Only if the lead itself is sound and it's only the joint that's failed. Nine times out of ten the lead has hardened and cracked too — a fresh point over cracked lead lasts one winter.
How long does new lead flashing last?+
30–50 years for Code 4 in a normal exposure. Longer with patination oil applied at install to stop the initial white staining that runs onto tiles below.
Do you cover the chimney pot and cowl too?+
Yes — if the pot needs re-flaunching or a cowl fitting, we price that separately in the quote so you can choose to include it or not.
Which Boldon postcodes do you cover?+
NE35 – NE36 — plus South Shields, Jarrow, Sunderland.
