Facade drone cleaning on Vancouver Island: the rules that decide it, the limits, and what moves the price

Facade drone cleaning is exterior building washing done by a water-fed drone flown from the ground, and we clean high-rise and commercial facades this way across Greater Victoria and the Capital Regional District.

On the south island the binding limit is airspace, not the method. A visual line-of-sight operation may not be flown within three nautical miles, about 5.6 km, of the centre of an airport, or within one nautical mile of the centre of a heliport (Canadian Aviation Regulations 901.47), and inside those distances a sheltered facade operation is permitted only under that facility's established drone procedure (CARs 901.73). A defence-operated aerodrome adds a second approval chain at the same three nautical miles, usable only with Department of National Defence authorisation (CARs 901.47(4)).

The pilot or a visual observer must also hold the aircraft in visual line-of-sight (CARs 901.11), so a four-sided tower is flown from several ground positions, and an elevation with no legal standing position is a coverage gap that belongs in the quote.

Cost follows height, not floor area. The Fixr window cleaning cost guide puts high-rise pane work at up to $85 per hour of labour, roughly $170 per hour once the required two-person crew is counted, and adds $3 to $5 per window from the third storey up. Estimates vary, so the real figure comes from a site assessment.

What the method takes off an island facade

A ground unit purifies and pumps the water, a tether hose carries it up, and the aircraft washes glass and cladding while the pilot flies from grade, so nobody is suspended over the building. The wash runs purified water at low pressure. Purified water dries without mineral spotting, which is why the glass needs no hand squeegeeing, and the low pressure suits the coated and sealed surfaces that a pressure washer can dull or drive water behind.

What comes off is the surface layer: salt film, airborne grime, organic staining and the algae that colonises shaded elevations. What does not come off is anything bonded into the substrate, etched glass, failed sealant or spalled concrete. Those are restoration work with a technician in contact with the envelope, not a wash. The method detail sits on the drone facade cleaning page; this one covers what changes when the building is on the island.

Why the aerodrome distances bite hardest here

Three nautical miles is a large circle to draw on a small island. Southern Vancouver Island carries an international airport on the Saanich Peninsula, a downtown harbour water aerodrome and hospital heliports inside a compact area, so a single commercial building can sit inside more than one buffer at once, each with its own established procedure to satisfy under CARs 901.73.

The defence rule is the one buyers do not see coming. It is a separate authorisation from a separate department, not a formality folded into the civil one, and it runs on its own timeline (CARs 901.47(4)). Ask whether any aerodrome near your building is a defence facility before a wash date is set rather than after.

Visual line-of-sight has a scheduling consequence too. Because the pilot or a visual observer must hold the aircraft in sight throughout (CARs 901.11), a tower is not one flight but several, repositioned around the building, and each position needs ground the crew may legally occupy. A courtyard elevation, a shared property line or a lane with no standing room is where the coverage gap appears.

The approvals behind the aircraft and the pilot

The aircraft's own approval. Registration is the floor. All drones weighing at least 250 g must be registered, and anything attached to a drone that pushes it to 250 g or more counts toward that weight (Transport Canada, registering your drone), which a cleaning aircraft carrying a pressurised tether clears many times over. Above that floor, Transport Canada runs an RPAS Safety Assurance rating system, and a drone must meet the relevant safety assurance requirements to conduct a specific advanced operation. Meeting the requirement for one operation does not make the aircraft fit for all of them (Transport Canada, choosing the right drone for advanced and complex operations). The separate standards cover operations in controlled airspace, near people and over people, so a model cleared to work near bystanders is not automatically cleared to work above them, and a sidewalk under an elevation is exactly that question.

The certificate the pilot holds and the survey they run. Transport Canada requires pilots to survey the area before the start of an operation and to determine whether the planned flight will be in or near controlled airspace, restricted airspace, or near any aerodromes, airports or heliports, using the Canada Flight Supplement, the Designated Airspace Manual and aeronautical charts (Transport Canada, where to fly your drone). Facade work close to a structure is a sheltered operation, which holds the drone no greater than 30 metres (100 feet) above the structure, less than 61 metres (200 feet) horizontally from it, and more than 30 metres (100 feet) from anyone not involved in the operation (Transport Canada, 2025 summary of changes to Canada's drone regulations). That is an Advanced privilege, not a Basic one.

An operator who has not looked at the airspace has not really quoted the job. Ask who obtains the authorisation and how far ahead of the wash date they do it.

Where we fly, and where the island line falls

We clean windows and facades across Greater Victoria and the CRD: Victoria, Saanich, Oak Bay, Esquimalt, View Royal, Colwood, Langford, Metchosin and Sooke. Location detail sits on the Victoria, Saanich, Oak Bay and Esquimalt pages.

That is a narrower area than "Vancouver Island", deliberately. Drone cleaning is a mobilisation-heavy service. A ground unit, a water supply, a pilot and a ground crew member have to reach the site, and a wind day pushes the flight to a contingency date. A tight service radius is what keeps a rescheduled flight cheap instead of expensive, and it is why an operator promising same-week coverage from Sooke to the north island should be asked how.

What coastal exposure does to an island building envelope

The island cleaning cycle is shorter than an inland one, and the reason is chemical rather than cosmetic.

Salt carried off the strait settles as a film on glass, aluminium composite panel, painted metal and precast concrete. That film is hygroscopic, so it holds moisture and airborne grime against the surface between rainfalls instead of letting them blow off. Steady winter rain then feeds algae and organic staining on the elevations that stay shaded, and on any track where a drip edge has shed water down the same line for years.

Two consequences matter to a budget. A waterfront or exposed tower soils faster than an inland one of the same age and glazing, so the cycles are not interchangeable across a portfolio. And a facade left uncleaned long enough moves from a wash into a restoration, which is a different trade at a different price.

What the method removes on the WorkSafeBC side

Rope access and swing stage are not unsafe. They are heavily regulated, and on an older island building that regulation is most of what makes them slow to mobilise.

WorkSafeBC requires a fall protection system wherever a worker could fall 3 m (10 ft) or more (WorkSafeBC, OHS Regulation Part 11). Rope work then adds its own requirements on top. A written rope access plan must be prepared and available at the workplace before a rope access system is installed or used, and it must set out the hazards, how they will be controlled, and a description of the system and its anchor locations. A permanent anchor must have an ultimate load capacity of at least 22.2 kN (5000 lbf) for each person connected to it, and it must be inspected at least once a year and tested, in accordance with CSA Standard Z91-02 (R2013) (WorkSafeBC, OHS Regulation Part 34).

That annual inspection is the part strata councils tend to miss when they compare methods. Anchors are not a one-time capital item. They are a recurring line with a recurring cost, and a building whose anchors have lapsed cannot be roped until they are re-certified, whatever the wash schedule says. For a strata whose roof carries no certified anchors at all, that single requirement is the whole story, and it is common on the mid-century concrete stock around Greater Victoria.

Drone cleaning moves the work off the envelope and onto an aircraft, which shifts the compliance burden from fall protection to aviation. Neither method escapes paperwork. What changes at street level is that there is no anchor load testing, no sidewalk closure under a suspended worker, and a shorter window in which residents keep windows shut and balconies clear.

What moves the price of an island facade job

Storey count is the obvious driver, and the published data agrees that height, not area, is what escalates. Beyond the high-rise hourly figures in the opening, the same cost guide puts ordinary glass at roughly $40 to $75 per hour, prices a single window at $8 to $40 depending on type and size, and adds $3 to $5 per window on the third and fourth floors alone, because reaching them needs ladders or lifts (Fixr, window cleaning cost guide). Those are third-party national figures, not our rate. The useful thing in them is the shape: the per-unit cost starts climbing at the fourth storey, long before a building is tall enough for anyone to call it a high-rise.

The quieter drivers are the ratio of glass to cladding, the soil condition after years without a cycle, whether the building sits under controlled airspace or inside an aerodrome distance, and how much of the elevation can be reached from grade. On most towers the podium and the first storey or two are still faster by pole from the sidewalk than by air, so a good quote splits the building rather than pricing it as one surface.

For a strata council, the useful framing is the depreciation report, which projects common property maintenance, repair and replacement costs over 30 years and must carry at least 3 cash-flow funding models for the contingency reserve fund over that period (Province of British Columbia, depreciation report requirements). A predictable wash cycle is a line a council can defend inside that projection. A neglected envelope that eventually needs restoration arrives as a special levy instead.

When facade drone cleaning is the wrong call on the island

Sustained wind postpones a flight, and on an exposed coastal site that happens more often than inland, so an island drone schedule carries a weather contingency date the way exterior painting does. A building that cannot get airspace authorisation for the window you need cannot be flown in that window. A facade needing contact work, sealant repair or restoration needs a technician on the envelope. And a low-rise building that already has certified, currently inspected permanent anchors can be quicker by rope.

Ask for both methods to be priced when the building supports both. An operator who will only quote one of them is selling a method rather than solving your building.

Get your island building looked at

Send the building address, the storey count and a rough sense of the elevation mix, and you get a written scope back for the work. No flat rate is published here, because a fourteen storey curtain wall tower inside an aerodrome distance and a six storey concrete walk-up in the suburbs are different flights with different airspace answers. Start with drone window and facade cleaning, or send the building details through the quote form.

Frequently Asked Questions

What is facade drone cleaning? Facade drone cleaning is exterior building washing done by a water-fed drone flown from the ground. A ground unit purifies and pumps water, a tether hose carries it up, and the aircraft washes glass and cladding while the pilot flies from grade, so no worker is suspended over the building. We clean high-rise and commercial windows and facades this way across Greater Victoria and the Capital Regional District.

How close to an airport or heliport can a cleaning drone fly? Under the Canadian Aviation Regulations a visual line-of-sight operation may not be flown within three nautical miles of the centre of an airport or within one nautical mile of the centre of a heliport, and a sheltered facade operation inside those distances is allowed only in accordance with the established drone procedure for that airport or heliport. Three nautical miles is about 5.6 km, so on the south island the check is building by building.

Why do island buildings get dirty faster? Coastal exposure. Salt film carried off the strait settles on glass and cladding and holds airborne grime against the surface, and steady winter rain feeds algae on the elevations that stay shaded. That drives a shorter cleaning cycle on a waterfront tower than on an inland one of the same age.

What does facade drone cleaning cost on Vancouver Island? No flat rate is publishable, because the flight, the airspace answer and the elevation mix differ building by building. As market context, the Fixr window cleaning cost guide puts high-rise pane work at up to $85 per hour of labour, and about $170 per hour once the two-person crew that work requires is counted. Those are third-party national figures, not our rate. Estimates vary, so the real number comes from a site assessment.

Does the drone itself need to be approved for the job? Yes. Transport Canada runs an RPAS Safety Assurance rating system, and a drone must meet the relevant safety assurance requirements to conduct a given advanced operation. Meeting the requirement for one operation does not make the aircraft fit for all of them, so the model flying your facade has to be declared for the operation being flown, not just registered.

When is rope access still the better method on the island? When the building already has certified permanent anchors, when the work needs contact with the envelope such as sealant repair or restoration, or when airspace authorisation cannot be obtained for the window you need. Ask for both methods to be priced when the building supports both.
