Drone Window Cleaning Singapore
High-level glazing, atria and skylights cleaned with deionised water from S$1.00 per square metre — for the glass that is awkward to reach and not worth rigging access equipment for.
Drone window cleaning in Singapore starts from S$1.00 per square metre of glazed area. Deionised water below 5 ppm dries streak-free with no squeegee or contact drying, which is what makes unattended aerial glass cleaning viable at all.
Key takeaways
- Rate: from S$1.00/sqm glazed area.
- Streak-free because DI water has no minerals to leave behind.
- Best use: glazing your regular cleaner cannot reach without rigging.
- Bundle it. Combining with facade or roof work in one visit is far cheaper.
- Not a fix for etching. Mineral staining etched into glass needs restoration, not washing.

Where drone window cleaning makes sense
Most buildings already have a window cleaning arrangement that works for accessible glazing. Drone cleaning is not trying to replace that. It is for the glass that arrangement cannot reach:
- Upper-storey glazing on buildings with no gondola track or davit provision
- Atrium and skylight glass where internal access means scaffolding over an occupied space
- Sheltered or recessed elevations that pole systems cannot reach from the ground
- One-off cleans where rigging access equipment costs more than the cleaning itself
- Buildings between cycles needing a clean before an event, inspection or handover
Why deionised water matters on glass
Tap water in Singapore carries dissolved minerals. Sprayed onto glass and left to evaporate, those minerals stay behind as spotting and streaking — which is why washing glass with untreated water and no squeegee looks worse afterwards, not better.
Deionised water below 5 ppm total dissolved solids has effectively nothing left to deposit. It dissolves soiling, runs off, and dries clear with no contact drying required. That property is the entire technical basis for aerial glass cleaning.
Drone window cleaning cost
| Scope | Typical price (SGD) | Notes |
|---|---|---|
| Small glazed elevation | S$1,800 | Minimum mobilisation |
| ~1,800 sqm glazing | From S$1,800 | One to two days |
| Atrium / skylight only | From S$1,800 | Priced on access complexity |
| Bundled with facade cleaning | Single mobilisation | Far cheaper than separate visits |
For most buildings the practical question is whether the glazed area justifies a dedicated mobilisation. If you are also cleaning the facade or roof, combining them into one visit is substantially cheaper.
What this will not remove
Hard-water mineral staining that has etched into the glass surface, cement or grout runoff, and scratch damage are not cleaning problems — they are restoration problems. Our parent business Lion City Glass handles those directly, so if the survey shows etching rather than soiling we will point you there rather than sell a wash that cannot fix it.
Frequently asked questions
How much does drone window cleaning cost in Singapore?
Drone window cleaning starts from S$1.00 per square metre of glazed area, with a minimum mobilisation of about S$1,800. Combining window cleaning with facade or roof work in one visit is substantially cheaper than separate jobs.
Does drone window cleaning leave streaks?
No. Deionised water below 5 ppm has effectively no minerals to deposit. It dissolves soiling, runs off and dries clear with no contact drying or squeegee needed. Untreated tap water is what causes streaking.
Can a drone clean windows on any building?
Most, but not all. Open glazed elevations work well. Deeply recessed windows, glazing under heavy overhangs, and buildings inside restricted airspace near Changi, Seletar or Paya Lebar may need alternative access or extra coordination.
