Facade cleaning costs in 2025: why drone cleaning cuts the insurance line by 70%
In brief: Drone cleaning runs NT$50–100/㎡ for the base service, 10–25% above rope access on unit rate. But insurance falls 70–80%, access equipment hire falls to zero, and labour falls 60–65%. On a 10,000㎡ building the total comes out NT$200,000–220,000 lower — 25–35% — with time on site down from 5–7 days to 2–3.
As construction has advanced, Taiwan's tall buildings have multiplied and the demand for facade cleaning with them. The traditional methods are slow, labour-intensive and carry real safety exposure. Drone facade cleaning has changed that materially in recent years.
What follows analyses current market rates and explains why drone cleaning, despite a slightly higher unit rate, comes out 25–35% cheaper in total — with the insurance line falling by 70–80%.
What drone facade cleaning is
Cleaning drones carrying a pressure lance and an environmentally sound detergent clean a building's facade precisely, from the air, with nobody climbing or riding a cradle. The safety improvement is substantial and the operation is considerably quicker.
The main advantages
1. A step change in safety
Traditional facade cleaning puts workers at height, with the fall risk that carries. Drone cleaning removes that exposure entirely, and with it the great majority of the occupational accident risk.
2. Materially faster
The aircraft moves quickly to wherever needs cleaning, with no scaffold to erect and no cradle to install. Across our own projects, the time on site is a fraction of what a traditional method needs.
3. Lower environmental impact
Drone cleaning uses less water and less detergent than traditional methods.
4. Better value
The unit rate may be slightly higher than traditional methods, but once time, labour and safety exposure are counted the overall economics are better.
5. Wider reach
The aircraft reaches positions traditional methods struggle with — unusual facade geometry, curtain walling, towers.
How a job runs
Step one: site survey and assessment
Our team attends site and assesses:
- Building height and structure
- Facade material and how heavily soiled it is
- The surroundings and the flying conditions
- Working hours and weather constraints
Step two: the cleaning plan
From the survey we produce a plan covering:
- Which aircraft type
- Which cleaning agent
- The working schedule
- The safety measures
Step three: preparation
Before work begins:
- Flight authorisation applied for as required
- Safety exclusion zone established
- Cleaning equipment and materials prepared
- Pre-flight checks completed
Step four: the work
- The aircraft follows the planned route
- A trained operator monitors throughout
- Cleaning parameters adjusted in real time
- Quality confirmed as the work proceeds
Step five: acceptance
- The result inspected
- Before-and-after photography
- A written report
- Client sign-off
Facade cleaning rates in 2025, compared
Before looking at how pricing works, here is the full cost comparison between rope access and drone cleaning.
Full cost comparison
| Cost item | Rope access | Drone cleaning | Difference | Change |
|---|---|---|---|---|
| Base service | NT$45–80/㎡ | NT$50–100/㎡ | — | 10–25% higher unit rate |
| Work-at-height insurance | NT$15,000–30,000 per job | NT$3,000–8,000 per job | NT$12,000–22,000 | 70–80% lower |
| Access equipment hire | NT$20,000–50,000 per job (cradle, scaffold) | NT$0 (equipment included) | NT$20,000–50,000 | 100% lower |
| Labour | NT$80,000–150,000 per job (6–10 crew) | NT$30,000–60,000 per job (2–4 crew) | NT$50,000–90,000 | 60–65% lower |
| Time on site | 5–7 days | 2–3 days | — | 60–70% shorter |
| Disruption to building operation | High — areas must close | Minimal — no closure needed | Not quantifiable | Substantially lower |
| Follow-up cost | High — uneven results need re-cleaning | Low — systematic coverage | — | 30–40% lower |
| Total (10,000㎡ building) | NT$650,000–900,000 | NT$450,000–680,000 | NT$200,000–220,000 | 25–35% lower |
Why the insurance line falls so far
Rope access involves people working at height, which requires substantial personal accident cover — typically 15–20% of the total cost. With drone cleaning:
- Nobody works at height — the operator flies from the ground, so no work-at-height cover is needed
- Equipment insurance costs less — cover for the aircraft is far cheaper than cover for people
- The risk profile is lower — insurers price accordingly
- Liability cover stays in place — we carry NT$10 million public liability and NT$5 million employer's liability regardless
A worked example:
- A 15-storey commercial building in Xinyi District, 12,000㎡
- Insurance on the traditional method: NT$28,000
- Insurance on drone cleaning: NT$6,500
- Saved: NT$21,500, a 77% reduction
How pricing works
Drone facade cleaning is priced against the following:
1. Area to be cleaned
The primary basis, calculated per square metre. Larger areas attract better unit rates.
2. Building height
Taller means harder and riskier, and the rate rises accordingly.
3. Facade material
Different materials need different treatment:
- Curtain wall glazing — comparatively straightforward
- Tiled facades — cleaned with a neutral agent
- Stone facades — need a specialist agent
- Metal facades — need corrosion-aware treatment
- Specialist coatings — need gentle cleaning
4. How heavily soiled
Heavier soiling means more passes and more cleaning agent, and a higher figure.
5. Operational difficulty
- Complexity of the surroundings
- Weather constraints
- Constraints on working hours, including night work
- Any special safety requirements
Indicative rates
In Taipei:
- Typical commercial or residential buildings: NT$50–100/㎡
- Curtain wall buildings: NT$50–80/㎡
- Structurally unusual buildings: NT$100–150/㎡
Note: these are indicative. The actual figure follows a site survey.

Frequently asked questions
Q1: Is drone cleaning more expensive than traditional methods?
A: On unit rate, drone cleaning runs 10–25% higher. On total cost — insurance, access equipment hire, labour and time on site together — it typically comes out 25–35% lower. The insurance line in particular falls by 70–80%. More detail: drone facade cleaning.
Q2: Why is the insurance so much cheaper?
A: Rope access requires substantial personal accident cover for people working at height. With drone cleaning the operators are on the ground, so no work-at-height cover is needed — only equipment and liability insurance. We carry NT$10 million public liability and NT$5 million employer's liability regardless of method.
Q3: Is drone facade cleaning safe?
A: Yes. Our operators are professionally trained and licensed, the aircraft are maintained on schedule, and full liability insurance is carried. Against traditional work at height, the safety improvement is substantial and the occupational accident risk approaches zero.
Q4: How often is cleaning needed, and does the cost mount up?
A: Every three to six months as a general rule, depending on:
- Where the building sits — urban or suburban
- The surroundings — traffic volume, nearby construction
- Climate
- Facade material
The interval is the same whichever method is used, but the cost per clean is lower with drone cleaning, so the long-run total is lower too.
Q5: What weather stops work, and does that affect the price?
A: Work does not proceed in:
- Rain, or with rain imminent
- Wind above Beaufort force 5
- Poor visibility
- Thunderstorms
We account for weather when quoting and schedule flexibly. Weather delays do not attract additional charges.
Q6: Could it damage the facade? Would repair cost extra?
A: No. Cleaning pressure and agents are set carefully so that the facade cleans effectively without damage. We carry public liability insurance, and any damage would be covered without additional cost to the client.
Q7: What do we need to prepare, and are there hidden costs?
A: Very little. We handle the technical and safety arrangements. What we need from you:
- A water and power connection point, at no charge
- Help notifying residents where necessary
- The working window reserved
Our quotations are itemised in full, with no hidden costs.
Q8: On a large building, does the cost become alarming?
A: No. Rates are tiered, improving with area:
- Under 5,000㎡: NT$80–100/㎡
- 5,000–10,000㎡: NT$70–90/㎡
- Over 10,000㎡: NT$60–80/㎡
And because the savings on insurance, equipment and labour scale with the job, the economics on a large building are better still.
Q9: Can we pay in instalments?
A: We accept a range of payment terms:
- Payment in full, with a 5% discount
- 30% deposit on signature, 70% on completion
- Instalment arrangements can be discussed on large projects
Q10: What does the price include? Will there be additions later?
A: The standard service includes:
- ✅ Site survey and 3D model
- ✅ The full cleaning operation
- ✅ Before-and-after photography and a report
- ✅ Public liability and employer's liability insurance
- ✅ Basic aftercare
Unless you request additional services — a specialist cleaning agent, night working — there are no further charges.
