FIXED-FEE QUOTE WITHIN 48 HOURS.
What sets the price of cleaning a building by drone, how it compares with rope access, gondola and scaffolding, and what to send us for a quote.
What Drives the Price
Every Skyline quote is a fixed fee for the whole job, built from the same six inputs. Two of them, facade area and soiling, decide most of the number. Height matters far less than it does for rope access, because the aircraft climbs a 55-story tower as readily as a 5-story one.
Facade area. The square meters we actually wash. A 20-story office tower is typically around 8,000 m². Floor plate and number of stories are enough for an estimate.
Surface material. Glass curtain wall cleans fastest. Stone, terracotta and textured concrete hold more grime and need slower passes at a pressure calibrated for the surface.
Soiling level. A facade cleaned last year is a maintenance wash. One that has not been touched in five years is a restoration and takes more passes.
Access and airspace. Where the ground team can stand, where the water supply is, and whether the site sits inside controlled airspace that needs additional CAAP coordination.
Timing. After-hours and weekend windows are available for hotels and occupied offices. They change the schedule, not the safety case.
Frequency. A quarterly or twice-yearly program is quoted as a whole and keeps every clean a maintenance wash rather than a restoration.
Where the Money Goes
| Skyline Drones | Rope access | Scaffolding or gondola | |
|---|---|---|---|
| Crew at height | None | Every shift | Every shift |
| Setup before cleaning starts | 30 min – 1 hour | Rigging and roof anchors, per drop | Days to weeks of erection |
| Cleaning rate | 1,000 – 2,000 m² per hour | ~100 m² per hour | ~100 m² per hour |
| 20-story tower, end to end | 2 – 4 days | 3 – 4 weeks | 4 – 6 weeks including erection |
| Permits and paperwork | CAAP flight permit, filed by Skyline | Work-at-height permits, anchor certification | Scaffold permits, street occupation |
| Tenant and public disruption | None, access maintained | Roof access, drops past windows | Blocked entrances for the duration |
| Insurance exposure | Aviation liability, no fall risk | Fall risk on every drop | Fall and collapse risk |
| How cost moves with height | Flat, flight time only | Steeply, more drops and rigging | Steeply, more tiers and ties |

Pricing Questions
Pricing depends on building height, facade material, surface area and access conditions. As a rule of thumb, drone facade cleaning matches or beats rope-access pricing on buildings above 30 meters, because the labor, scaffolding and insurance overheads of working at height are removed. We provide a fixed-fee quote within 48 hours of receiving a building photo and address.
Mobilization, the CAAP flight permit and risk assessment, airspace coordination, the pilot crew and ground team, deionized water and calibrated spray for your facade material, third-party liability cover for the job, and a completion report with before-and-after imagery. There is no scaffolding, rigging or rope-crew line item.
Less than you would expect. A drone climbs a 55-story tower as readily as a 5-story one, so height mostly affects flight time rather than crew size or rigging. Rope access and scaffolding costs scale steeply with height, which is why the drone advantage grows above 30 meters.
Yes. Tell us the frequency you want, whether quarterly, twice a year or annual, and we quote the program as a whole. Recurring clients get priority scheduling in their preferred windows, including after-hours and weekend slots that avoid tenant disruption.
The building address, the number of stories, the facade materials if you know them, a photo of one or two elevations, and your preferred timing. From that we can price most buildings without a site visit. Complex facades get a free site assessment before the fixed fee is issued.
