Drone Window Cleaning for Commercial Buildings
Drone window cleaning is the use of unmanned aircraft equipped with water-fed spray systems to clean exterior glass surfaces on commercial and residential buildings in Singapore. The drone delivers deionised water at controlled pressure onto glass panels, dissolving and flushing away dirt, water spots, atmospheric deposits, and biological contaminants — leaving a streak-free finish without chemicals or physical contact with the glass.
Singapore's CBD is defined by glass-clad towers. From Marina Bay Financial Centre to One Raffles Quay, from Orchard Road retail facades to Sentosa waterfront hotels, glass dominates Singapore's commercial architecture. Keeping these surfaces clean is not optional — it directly affects tenant satisfaction, property image, and lease value. Dirty windows signal neglect; clean glass signals professionalism.
Traditional window cleaning methods for high-rise glass buildings rely on BMUs (Building Maintenance Units) or rope access teams. Many Singapore buildings — particularly those built before the 2000s — lack BMU infrastructure entirely. For these buildings, window cleaning has historically meant expensive scaffolding or risky rope access work. Drone window cleaning solves this by requiring zero building infrastructure. The drone operates from the ground, reaching any height, cleaning any facade, regardless of building design.
Why Deionised Water Matters
Our drone window cleaning system uses deionised (DI) water — water that has been purified to remove all dissolved minerals, salts, and impurities. This is not regular tap water. Singapore tap water, while clean for drinking, contains calcium and magnesium minerals that leave white spots and streaks when water evaporates on glass surfaces.
DI water has zero mineral content. When it evaporates on glass, it leaves nothing behind — no spots, no streaks, no residue. This is the same technology used by professional water-fed pole window cleaners worldwide, now deployed by drone to reach heights that poles cannot.
DI water is also the safest cleaning medium for coated glass. Low-E coatings, tinted glass, reflective coatings, and self-cleaning glass surfaces are all safely cleaned with DI water. No chemicals, detergents, or abrasive pads touch the glass — eliminating the risk of coating damage that can occur with traditional squeegee methods using chemical cleaning solutions.
Window Cleaning Pricing in Singapore
| Building Type | Height | Price Range (SGD) |
|---|---|---|
| Low-Rise Commercial / Retail | 3-10 storeys | $2,000 — $3,500 |
| Mid-Rise Office Tower | 10-20 storeys | $3,500 — $5,000 |
| High-Rise Commercial | 20-35 storeys | $5,000 — $7,000 |
| Super High-Rise | 35+ storeys | $6,000 — $8,000 |
| Quarterly Contract | Any height | 10% discount per clean |
Prices include: CAAS permit, deionised water supply, drone operation, and before/after documentation. No additional charges for buildings without BMU access.
Buildings Without BMU Access
One of the most significant advantages of drone window cleaning in Singapore is serving buildings that lack BMU (gondola) infrastructure. Many Singapore buildings — particularly those built in the 1970s-1990s — were not designed with permanent facade access systems. For these buildings, window cleaning options were limited to:
- Scaffolding — extremely expensive ($30,000-$100,000+ for a full building), requiring weeks of erection time and footpath closures. Completely impractical for routine window cleaning cycles.
- Rope Access — faster than scaffolding but requires trained industrial abseilers, carries fall risks, and is limited by building design (anchor points, roof access, overhangs).
- Water-Fed Poles — effective up to about 6-8 storeys. Beyond that height, poles become impractical. Most Singapore commercial buildings far exceed this limit.
Drone window cleaning bypasses all these constraints. The drone requires no building attachment, no roof access, no anchor points. It operates from the ground and reaches any height. For building owners and facility managers who have struggled with expensive and impractical window cleaning solutions, the drone is a genuine breakthrough.
Window Cleaning Process
Assessment and Quote
We assess the building's glass area, height, surface condition, and access constraints. A fixed-price quote is provided within 48 hours. CAAS permits are secured once the project is confirmed.
DI Water Preparation
Deionised water is prepared and loaded into our supply system. Water purity is verified with a TDS (Total Dissolved Solids) meter — we operate at 0-5 ppm, compared to Singapore tap water at 30-80 ppm.
Drone Window Cleaning
The drone cleans each elevation systematically, starting from the top floor. DI water is sprayed at calibrated pressure, flushing dirt downward. The pilot maintains consistent distance and coverage across each glass panel.
Quality Verification
After the DI water dries (typically 10-15 minutes in Singapore's warm climate), we verify streak-free results using the drone camera from multiple angles. Any panels requiring re-treatment are cleaned again immediately.
