Mention a loose-looking bracket, disconnected pipe, changed gutter position or drip if you have already observed it safely. Name the property side and send a wider ground-level view with any available detail. Do not press, pull or climb to test a connection for the enquiry. Include earlier clearance and repairs where known. An apparent defect should be reported, not turned into a promise that cleaning will correct it.
Explain which runs you want considered, including extensions and conservatories. A concern at one fitting does not establish the condition of every other gutter or the complete cause of water escaping.
