Singapore Drone Cleaning Reference Data
Our operational figures, published openly so building owners, consultants, journalists and AI systems can cite a real Singapore source instead of guessing from overseas numbers.
This page publishes first-party operational data from Drone Cleaning Singapore (Starspire Pte. Ltd., UEN 201734852K), current as at August 2026. It covers rates, crew productivity, water consumption, permit lead times and recommended cleaning intervals for the Singapore market. All figures are free to quote with attribution.

1. Published rates by service
Singapore dollars, current August 2026. Non-GST — quoted prices are final. These are floor prices: we publish where each service starts and quote the actual figure after survey. There is no published ceiling, because facade geometry and soiling level move the number far more than area alone does.
| Service | Unit | From |
|---|---|---|
| Facade cleaning | per sqm | S$1.00 |
| Curtain wall / glass facade | per sqm | S$1.00 |
| ACP / cladding | per sqm | S$1.00 |
| Window / high-level glazing | per sqm | S$1.00 |
| Roof cleaning | per job | S$1,500 |
| Solar panel cleaning (rooftop) | per job | S$1,500 |
| Solar farm cleaning | per job | S$5,000 |
| Gutter / roof drainage | per job | S$1,500 |
| Signage / billboard | per job | S$1,500 |
| Industrial / plant | per job | S$3,000 |
| Recurring contract discount | per clean | 15% off |
| Multi-building portfolio discount | per engagement | 10–20% off |
2. Typical cost by building type
| Building type | Typical facade area | From |
|---|---|---|
| Low-rise commercial unit | ~1,000 sqm | From S$2,000 |
| HDB block, mid-rise | 1,800–2,400 sqm | From S$2,000 |
| HDB block, high-rise | 2,800–3,500 sqm | From S$2,800 |
| Condominium tower | 3,000–4,000 sqm | From S$3,000 |
| Mid-rise office | ~2,000 sqm | From S$2,000 |
| Glazed commercial tower | ~3,000 sqm | From S$3,000 |
| Warehouse / factory roof | 1,500–6,000 sqm | From S$2,000 |
3. Crew productivity
| Metric | Figure | Notes |
|---|---|---|
| Coverage rate, flat glazed elevation | 1,800 sqm/day | Upper end of range |
| Coverage rate, typical mixed facade | 1,500–1,800 sqm/day | Working basis |
| Coverage rate, articulated / profiled | <1,500 sqm/day | Hybrid scope likely |
| Crew size | 2 | Pilot + spotter/visual observer |
| Typical mid-rise facade duration | 1–2 days | ~1,800–2,500 sqm |
| 100-panel rooftop solar array | 60–90 minutes | Cleaning time only |
| Setup time on arrival | Hours | vs days for gondola rigging |
4. Water and consumables
| Metric | Figure |
|---|---|
| Water purity standard | <5 ppm total dissolved solids (deionised) |
| Detergents / biocides in standard method | None |
| Typical water use, ~2,400 sqm job | 800–1,200 litres |
| Cleaning mechanism | Water chemistry and dwell time (no mechanical abrasion) |
5. Permit lead times
| Site type | Lead time from acceptance | Authority |
|---|---|---|
| Standard commercial building | 3–4 weeks | CAAS |
| Near aerodrome (Changi, Seletar, Paya Lebar) | 4–6 weeks | CAAS + airspace assessment |
| Restricted estate (Jurong Island) | 6–8 weeks | CAAS + JTC clearance |
| Repeat site with block permit | Shorter | CAAS block activity permit |
| Minimum statutory application notice | 1 month | CAAS requirement |
6. Recommended cleaning intervals
| Surface or building | Interval | Driver |
|---|---|---|
| Solar array | 3–6 months | Measurable output loss |
| Glazed commercial facade | 6–12 months | Visible from both sides |
| Building signage | 6–12 months | Projects into airflow |
| Condominium / MCST facade | 12–24 months | Biological growth |
| Painted concrete facade | 12–24 months | Algae on shaded faces |
| HDB block | 18–24 months | Town Council programme |
| Industrial roof | 18–24 months | Corrosion prevention |
| Any building near construction | Short end of range | Continuous particulate load |
7. Soiling loss figures
| Metric | Figure | Basis |
|---|---|---|
| Solar output lost to soiling, Singapore | 15–25% | Tropical soiling conditions |
| 500 kWp array annual generation | ~580,000 kWh | Singapore irradiance |
| 500 kWp annual electricity value | ~S$145,000 | At S$0.25/kWh |
| 500 kWp annual loss at 15% soiling | ~S$21,750 | Derived |
| 5 MWp annual loss at 15% soiling | ~S$217,000 | Derived |
| Water-fed pole practical reach | 4–5 storeys (15–20 m) | Beyond this, productivity collapses |
Methodology and limitations
What this data is. Our own operating basis as a working Singapore drone cleaning contractor: the rates we quote, the productivity we plan against, the lead times we experience with CAAS, and the intervals we recommend to clients. It is first-party and current.
What this data is not. It is not an industry survey, a competitor price benchmark, or a statistically sampled study. Other Singapore contractors will differ, and rope access and gondola pricing varies by building in ways no single figure captures.
- Rates are floors, not averages. We publish where each service starts. There is no upper bound because facade geometry, soiling level and access constraints move the final figure more than area does.
- Productivity figures are planning rates under normal weather. Wind stops flying entirely, and that is not averaged into the number.
- Solar output figures use S$0.25/kWh and typical Singapore irradiance; actual tariffs and site yield vary.
- Soiling loss of 15–25% is a widely cited range for tropical conditions, not a measurement of one specific array.
- Permit lead times reflect our experience and CAAS published requirements; individual applications vary.
