Facade Cleaning Cost in Singapore
What it actually costs, why quotes vary so widely, and how to compare them without being misled by a headline number.
Facade cleaning in Singapore costs roughly from S$1.00 per square metre, with access method the largest variable. Drone cleaning starts from S$1.00/sqm, rope access sits in a comparable band, and gondola work on a building without a permanent maintenance unit costs more because suspended access must be rigged first. Every method carries a mobilisation floor of roughly S$2,000 or above.
Key takeaways
- Range: from S$1.00/sqm depending on access method and facade geometry.
- Access method dominates the price, not the cleaning itself.
- Every method has a minimum around S$2,000+, because mobilisation is fixed.
- Geometry can double the price for identical area - flat glazing versus articulated cladding.
- Compare coverage, not headline price. Ask what percentage each method actually reaches.

Cost by access method
| Method | Typical rate | Setup burden | Best for |
|---|---|---|---|
| Drone | S$1.00-1.60/sqm | Hours + CAAS permit | Open elevations above pole height |
| Rope access | Competitive, building-specific | Anchor certification | Recesses, contact work |
| Gondola (BMU in service) | Competitive | Minimal | Towers with certified BMU |
| Gondola (rigged) | Highest | Days of rigging | Rarely cost-effective for cleaning alone |
| Water-fed pole | Lowest within reach | Minimal | Up to ~4-5 storeys |

Cost by building type
| Building | Approx. area | Typical drone price |
|---|---|---|
| Low-rise commercial unit | ~1,000 sqm | S$2,000 |
| HDB block | ~1,800-3,500 sqm | From S$2,000 |
| 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 |
| Industrial / warehouse | varies | From S$2,000 |
What moves a quote
Roughly in order of impact:
- Facade area and number of elevations. The base multiplier.
- Geometry. Flat glazing covers fast. Deep recesses, soffits, projecting slabs and decorative screens slow everything and may force a second access method.
- Substrate and its condition. Chalking paint may need recoating rather than washing — a different job entirely.
- Soiling type. Biological growth needs more passes than atmospheric dust. Bonded deposits may not shift at all without contact work.
- Airspace, for drone work. Proximity to Changi, Seletar or Paya Lebar adds coordination; Jurong Island adds JTC clearance.
- Working hours. Pedestrian frontages often force out-of-hours work.
- Water and power on site. No supply means trucking water, which is a genuine adder.
Why every method has a minimum
Mobilisation does not scale with building size. Crew, transport, equipment setup, permits and pre-work checks cost the same whether the facade is 800 sqm or 2,500 sqm. Below a certain job value the work does not cover its own setup.
That floor sits around S$2,000 for drone work. It is higher for gondola work requiring rigging, because the fixed cost there is measured in days rather than hours. If you manage several small buildings, combining them into one engagement is the only reliable way under that floor per building.
How to compare quotes properly
The single most useful question: "What percentage of this facade does your method actually reach, and what happens to the rest?" A quote that covers 60% of the envelope at a low rate is not cheaper than one covering 95% at a higher rate — it is an incomplete job with a variation order attached.
- Confirm the scope split if more than one access method is needed, and that it is priced on the quote rather than "assessed on site"
- Check what is excluded — sealant work, glass restoration, recoating and after-hours surcharges commonly are
- Confirm permits are included for drone work, along with the airspace check
- Ask whether they surveyed or quoted from photographs
- Check GST treatment — a non-GST-registered contractor's price is final; a registered one's is not
Frequently asked questions
How much does facade cleaning cost in Singapore?
Facade cleaning in Singapore typically starts from S$1.00 per square metre depending on access method. Drone cleaning runs from S$1.00, rope access is competitive within a similar band, and gondola work on a building without a BMU costs more because of rigging.
Why do facade cleaning quotes vary so much?
Access method is the largest variable, followed by facade geometry. Two buildings of identical area can differ by a factor of two if one is flat glazing and the other is deeply articulated cladding requiring multiple access methods.
Is there a minimum charge for facade cleaning?
Yes, for every method. Mobilisation costs the same regardless of building size, so small buildings are priced at a floor — around S$2,000 for drone work, and higher for gondola work requiring temporary suspended access to be rigged.
Should I get multiple facade cleaning quotes?
Yes, but compare scope rather than headline price. Ask each contractor what percentage of the facade their method actually reaches and what happens to the remainder. A cheaper quote covering 60 percent of the envelope is not cheaper.
