Drone Facade Cleaning
and Facade Inspection
No scaffolding, no road closures — crews operate from the ground throughout. From a facade health check that finds hollow tiles and cracks, through to the cleaning and protective coating that follow.

The Cost of a Single Tile
Incident
One tile falling on a person
Seven figures and up
Plus criminal liability, civil litigation, a collapse of community trust, and public-liability premiums that rise every year after.
And tiles never fall without warning. There are signs first: hollowing, cracking, seepage, corrosion.
These signs are invisible from the ground.
But visible from the air.
— 003 · Work in the Field
The buildings we've done — and the details to prove it.
Every job has its own constraint: an office that cannot stop trading, residents who need their laundry line, a fab that permits clean water only. Here is how we actually handled them.

What condition is your facade in?
Three questions, 30 seconds. Find out which risk group your building belongs to.
Q1 / 3
How old is your building?
— 005 · Facade Health Program
This isn't a one-off cleaning contract. It's an ongoing relationship.
And after the inspection? Diagnose, treat, track, budget — four phases in one annual cycle. Your building gets a medical record that grows every year; your CFO gets a five-year maintenance budget forecast.
01 · DIAGNOSE
Diagnose
A full-building scan in half a day. AI reads 13 classes of facade defects; infrared thermal imaging sees hollowing behind the tiles. What you get isn't a stack of photos — it's an asset health report with coordinates, severity grades, and trends.
02 · TREAT
Treat
The diagnosis decides what happens. Clean what needs cleaning, coat what needs coating, and what needs repair is handled by our own rope access team.
03 · TRACK
Track
Next year we come back and compare — not new photos, but the same wall against last year. Deterioration rate, spread direction, risk curve.
04 · BUDGET
Budget
You get a five-year maintenance budget forecast. This is what your CFO actually needs.
We will never recommend cleaning just to sell cleaning.
— 006 · Why Us
Others sell labour hours. We sell interpretation — and build our own machines.
INSPEK AI
In-House Defect-Reading AI
inspek — 13 fine-grained defect classes. Not a generic model; trained on real Taiwanese building facades.
IN-HOUSE R&D
Our Own Cleaning Drone · NDAA Compliant
Wind shear against a wall, nozzle recoil, multipath signal — no off-the-shelf airframe was designed for these. Our R&D team builds a purpose-built platform on an NDAA-compliant, non-PRC supply chain.
SAFETY
A Digitised Safety System
A written operating safety procedure, with risk assessments, checklists and work records digitally filed and traceable per job, in line with Taiwan's occupational safety and health regulations.
— 007 · Our Technology
We build the machines that clean and inspect.
Off-the-shelf drones were never designed to fly against a wall. We have our own R&D team — building for our own fleet, and taking on drone development work for outside clients.

— 008 · Enterprise-Grade Assurance
Hand your facade to a company, not to one person.
When high-rise facade work goes wrong, the building committee and the owner are the ones facing joint liability. We put the answer to "who carries the risk" into insurance policies and written procedure — not into verbal promises.

CAA REVIEW
Cleared under the CAA capability review
The company holds a Remote Drone Operator Capability Review approval from Taiwan's Civil Aeronautics Administration (valid through Dec 2027). The review assesses the whole organisation — personnel, equipment and operating capability — not just one pilot's certificate.
LIABILITY COVER
NT$10M public liability · NT$5M employer's liability
We carry NT$10,000,000 in public liability insurance and NT$5,000,000 in employer's liability insurance. Copies of both policies are available for inspection before you sign — coverage amounts and validity dates included.
SAFETY SYSTEM
Occupational safety written down, not improvised
On-site risk assessment before every job, pre-flight equipment checklists, defined wind-speed and weather abort thresholds, ground cordon and access control — all digitally filed and traceable per job, in line with Taiwan's occupational safety and health regulations. Crews stay on the ground throughout — zero fall exposure.
OWNED CAPABILITY
Our own AI, our own flight stack, our own fleet
inspek defect-reading AI and the GDS-Pilot flight controller are both developed in house, and the aircraft and thermal imaging hardware are ours. No outsourced pilots, no equipment rented for the day.

Below are the questions owners and management committees ask most. Feel free to contact us with anything else
It turns facade maintenance from a one-off contract into an ongoing management relationship. One cycle per year: diagnose (full-building scan and AI interpretation), treat (cleaning, coating, or flagged repairs based on the diagnosis), track (comparing the same wall against last year), and budget (a five-year maintenance forecast). Your building builds a medical record that grows every year.
