Drone Signage Cleaning
Building signage, roof-level logos and high billboards cleaned from the air — no boom lift on the forecourt, no road closure, no scaffolding for a two-hour job.
Drone signage cleaning starts from S$800 as a standalone job, and much less when added to facade cleaning on the same visit. Signage is a classic case where the access cost dwarfs the cleaning: mobilising a boom lift and closing part of a forecourt for a two-hour clean is disproportionate, which is why building signage often goes years untouched.
Key takeaways
- Price: From S$800 standalone; small addition alongside facade work.
- Access cost, not cleaning cost, is what makes conventional signage cleaning expensive.
- Isolate illuminated signage before any water is applied - coordinated with your FM team.
- Signage soils faster than facades - it projects into the airflow and attracts insects at night.
- Brand visibility is the actual deliverable; a soiled logo reads as a neglected building.
Why signage is a disproportionate job
A building sign is small. The problem is that it is usually mounted at the highest, least accessible point of the elevation, often overhanging a forecourt, entrance canopy or public footpath. Reaching it conventionally means a boom lift, a traffic management plan, and possibly an out-of-hours permit — for a clean that takes under two hours.
That imbalance is why signage tends to be cleaned only when the whole facade is done, and looks poor for years in between. A drone flies to it directly, cleans it, and leaves.
Illuminated and LED signage
Most commercial signage is illuminated, which introduces the one genuine constraint: the sign must be isolated and powered down before water is applied, and left to dry before re-energising. We coordinate that with your facilities team as part of scheduling.
Low pressure matters here too. Sign housings, LED modules and cable entries are sealed to shed rain, not to resist directed high-pressure water. Deionised water at low pressure cleans the face without testing those seals.
What we clean
- Building-mounted signage and logos at roof or parapet level
- Illuminated box signs and channel letters (isolated before work)
- High-level billboards and advertising panels
- Entrance canopy and podium signage above public circulation
- Directional and wayfinding signage on tall structures
Signage cleaning is usually best bundled with facade cleaning — the crew, permit and water setup are already on site, so the marginal cost is small.
Frequently asked questions
How much does drone signage cleaning cost in Singapore?
Drone cleaning of building signage and high-level billboards typically starts from S$800 as a standalone job, or a small addition when combined with facade cleaning on the same visit.
Can you clean illuminated signage safely?
Yes, with the sign isolated. Illuminated and LED signage must be powered down before water is applied, which we coordinate with your facilities team. Deionised water and low pressure avoid driving moisture into housings and seals.
Why does high-level signage get dirty so fast?
Signage sits proud of the facade and catches airborne particulates from all directions, while the illumination attracts insects at night. Sign faces often look soiled within months even when the surrounding facade still reads clean.
Signage let the building down?
Send a photograph from ground level. We can usually quote signage without a site visit.
