Say whether you know the gutter type or finish, and describe visible wear, marked outside faces or earlier changes. You do not need to identify a material by scraping it or climbing to inspect it. Wider ground-level views show the gutter position and surrounding boards; a safely available detail can add useful context. If information is uncertain, explain that rather than selecting a cleaning method yourself.
Name main runs, extension and conservatory gutters wanted. Include earlier clearance and known repairs. The request should say which channels and surfaces need attention, without assuming a single room or roofline label includes every adjoining component.
