Local context — leadwork in Welwyn Garden City
Leadwork is our biggest USP and the kind of work that's hardest to find done properly in Welwyn Garden City. The whole garden city core is a conservation area with restrictive covenants held by the Howard Trust — like-for-like tile colour, matching ridge and unchanged chimney pot profile are non-negotiable, and we handle Trust liaison at quote stage. We work to Lead Sheet Association guidance on every job — code 4 for cover flashings, code 5 for valleys and abutments, code 6+ for bay and dormer roofs — and we weld on site rather than relying on mastic.
We work across AL7, AL8 with easy access from A1(M) Junction 4 and A414.
