Look during rain if it is safe to do so

Dry-weather inspection can miss the behaviour completely. From ground level, observe whether joints drip, water overshoots the gutter or staining follows the wall below an outlet.

The damp patch can sit away from the blockage

A blocked outlet can make water rise along the gutter until it spills at the lowest edge. The internal stain may therefore appear below the overflow point rather than below the blockage itself.

Repeated wetting affects more than plaster

Saturated masonry can keep timber lintels, fascia ends or joist bearings damp. Repairing the gutter early can prevent a simple rainwater defect becoming a timber-decay problem.
