Inspect signs in daylight and after dark
Daytime review reveals fading, cracks, corrosion, loose trim and damaged graphics. Night inspection reveals failed modules, colour shifts, hotspots and timing problems. Photograph each elevation from the same location so changes can be compared over time.
What to record
Maintain an inventory with sign type, location, installation date, electrical circuit, access method and known component specifications. This reduces diagnosis time and helps teams order compatible replacement parts.
- Loose panels, fasteners or letter faces
- Water entry, staining or corrosion
- Dark or uneven illuminated sections
- Peeling vinyl and damaged wrap edges
- Vegetation, snow or objects blocking visibility
Prioritize safety-related conditions
A loose face, leaning ground sign, exposed wiring or blocked emergency information requires prompt attention. Do not ask unqualified staff to open energized cabinets or work at height. Isolate the area if necessary and arrange an appropriate sign or electrical service provider.
Set inspection frequency according to exposure and consequence. A high pylon beside traffic, an illuminated rooftop sign and a temporary interior graphic do not carry the same risk. Record completed repairs with photographs, parts used and the next review date so maintenance history remains useful when staff or contractors change.
