HDB Facade Cleaning by Drone
Block facades, high-rise ledges and common-area elevations cleaned from the air — one to two days per block instead of a week of gondola rigging above people's homes.
Drone cleaning of an HDB block typically starts from S$2,500, at S$1.00-1.60 per square metre of elevation. HDB is the strongest residential case for drone work because the alternative disrupts residents for days. In October 2025 MND and HDB trialled drones for washing high-rise ledges, citing reduced risk and cost.
Key takeaways
- Price: From S$2,500 per block, S$1.00-1.60/sqm.
- Duration: one to two days per block, versus a week or more to rig a gondola.
- Commissioned by the Town Council — individual residents cannot appoint a facade contractor.
- High-rise ledges are the specific problem drones were trialled on: awkward, dangerous, and slow by any other method.
- Permits: CAAS Activity Permit filed at least one month ahead; we handle it.

Why HDB suits drone cleaning
An HDB block is a tall, repetitive, largely flat elevation with continuous painted concrete and regular openings. That geometry is close to ideal for a drone: few deep recesses, no complex cladding transitions, and long uninterrupted runs the drone can cover in systematic passes.
The stronger argument is disruption. Rigging a gondola on a residential block means noise, restricted corridor access, and workers moving past bedroom and living-room windows for days. Every one of those is a complaint to the Town Council. A drone crew works from ground level for one to two days and leaves.
High-rise ledges: the specific problem
Ledges are the reason drone cleaning entered HDB estates at all. They accumulate bird soiling, windblown litter and biological growth, they are visible from every unit above, and they are genuinely hazardous to reach — a worker on a ledge at height is the exact scenario Singapore's workplace safety regime exists to prevent.
A drone reaches a ledge in seconds with no anchor point, no harness and no one leaning over a parapet. That is why the MND and HDB trial focused on ledge washing specifically rather than whole-facade cleaning.
Who commissions the work
Facade and common-area cleaning on HDB estates is managed by the Town Council, which holds responsibility for common property and appoints contractors. Individual flat owners cannot commission facade cleaning for a block, though they can raise the request through their Town Council or grassroots channels.
For managing agents, the practical advantage of a drone quote is that it is a single fixed number with a short site window — easier to table at a council meeting than a multi-week access programme with its own risk assessment.
HDB facade cleaning cost
| Block type | Approx. elevation area | Typical price (SGD) |
|---|---|---|
| Low-rise block (up to 5 storeys) | ~1,200 sqm | S$2,500 |
| Mid-rise block (10-16 storeys) | ~1,800-2,400 sqm | From S$2,500 |
| High-rise block (20-30 storeys) | ~2,800-3,500 sqm | From S$2,800 |
| Ledges only | varies | From S$1,800 |
| Multiple blocks, one estate | - | 10-20% volume discount |
Estate-wide engagements are where the economics improve sharply: one mobilisation, one permit cycle, and a crew that is already on site. See the pricing page for the full rate card.
Managing resident disruption
- Notice period — we provide advance notice text for Town Council circulars and lift-lobby notices
- Ground exclusion zone below the working elevation, moved progressively rather than closing the whole block
- Laundry and window advisories — residents on affected faces are asked to retract poles and close windows for the working window only
- Scheduling around peak hours where the block fronts a busy void deck or walkway
Frequently asked questions
Can drones clean HDB blocks in Singapore?
Yes. HDB blocks are among the best-suited buildings for drone cleaning because gondola and rope access disrupt residents for a week or more. The Ministry of National Development and HDB trialled drone washing of high-rise HDB ledges in October 2025.
How much does HDB facade cleaning cost with a drone?
Drone cleaning of an HDB block typically starts from S$2,500 depending on block height and elevation area, at a rate from S$1.00 per square metre. Final price is fixed after survey.
Who authorises facade cleaning on an HDB block?
The Town Council manages common property on HDB estates and appoints cleaning contractors. Individual residents cannot commission facade cleaning. Drone operations additionally require a CAAS Activity Permit filed at least one month ahead.
Does drone cleaning disturb HDB residents?
Far less than conventional access. There is no scaffolding, no gondola rigging and no workers passing windows over several days. A typical block is completed in one to two days, with a ground exclusion zone rather than sustained disruption.
