Facade glazing cleaned by rope access, building maintenance unit or swing stage, whichever the building is actually rigged for. Towers, strata buildings and mid-rise commercial facades across the Sydney CBD, North Sydney, Parramatta and the eastern and inner suburbs. Police-checked, directly employed crews and 20 million public liability cover.
High rise window cleaning in Sydney is performed by rope access, a roof-mounted building maintenance unit, or a swing stage, depending on what the building is rigged for. Most commercial towers run two to four external cleans a year. Every job is quoted after a site assessment that confirms anchor points, access routes and ground level exclusion zones.
The access method is not a preference, it is a property of the building. Sydney towers built or refurbished in the last three decades usually carry a building maintenance unit on the roof, a davit or cradle rig designed for the facade it sits above. Where the unit exists, has a current inspection record and reaches the elevations in question, it is the fastest and least disruptive option, because the crew works from a stable platform and the street below stays open.
Rope access takes over where the cradle stops. Older buildings without a unit, facades with deep reveals, blade walls, angled curtain wall or plant screens, and buildings where the cradle cannot track past a setback all get worked on twin ropes from certified roof anchors. It is quieter, needs far less set-up time, and reaches geometry a rigid platform never will. The trade-off is a tighter weather window and a mandatory ground level exclusion zone below every drop.
Swing stage and elevated work platforms cover the rest, which in practice means podium levels, setbacks, atrium roofs, awnings and anything up to roughly the height a boom can reach from a hardstand. Low-level glazing, shopfronts and ground floor curtain wall are handled from the ground with water-fed poles running filtered water, which dries without leaving mineral spotting and avoids putting a person on a ladder over a footpath. Most Sydney buildings need at least two of the four, and the scope should say which method applies to which elevation.
Site assessment first, then a scope that names the access method for every elevation. No lock-in contract.

Permanent anchor and static line systems on Australian buildings are installed and periodically recertified against the height safety standards, and the test record is held by the building owner or the facility manager rather than by the cleaning contractor. The first thing we ask for is that record. If it has lapsed, the clean waits until a height safety engineer has retested the system, because a certificate that expired two years ago tells you nothing about the bolt in the concrete today.
The same applies to a building maintenance unit. Cradle rigs carry their own inspection and load test regime, and an overdue unit is not usable no matter how recently it was driven. Where a building has neither a current anchor system nor a serviceable cradle, the honest answer is that the facade cannot be cleaned safely from above and the scope moves to elevated work platform access from the ground, which changes the cost and the traffic management requirement significantly.
Below the building, the ground level plan matters as much as the roof. Every drop needs an exclusion zone with barriers and a spotter, and in the CBD that frequently means a footpath occupancy approval from the City of Sydney, a pedestrian diversion, and work timed to avoid the morning and evening peaks. Buildings with a loading dock, a childcare tenancy, a school route or an outdoor dining licence underneath need the zone designed around them. We put this into the scope at quoting stage rather than discovering it on the first morning.
Sydney glass gets dirty in patterns you can predict from a map. Buildings within the marine aerosol band, roughly the harbour foreshore and the coastal strip from Manly through the CBD to Maroubra, collect salt that attracts moisture, holds dust against the pane and leaves a haze that is obvious in low afternoon sun. Salt also sits in the glazing gaskets and the drainage channels, which is why a proper external clean flushes the frames and not only the glass.
Traffic corridors produce a different film. Brake dust and diesel particulate bond to glass with an oily carrier that plain water will not lift, so facades on the Pacific Highway at North Sydney and Chatswood, on Parramatta Road, and around the Anzac Bridge approaches need a detergent stage rather than a rinse. Construction is the third variable. Any building within a block of an active site collects cement dust, and cement dust that is left to weather etches glass permanently. That is a reason to bring a clean forward, not to postpone it until the development finishes.
Bird pressure is the last one, and it is worse than most building managers expect on harbourside and park-facing towers. Droppings are acidic, they mark glass and anodised frames within days in summer heat, and on ledges and sunshades they build up into a genuine hygiene problem for anyone doing plant maintenance. Where a facade has a persistent problem we flag it for proofing rather than pretending a quarterly clean will fix it.
A residential strata tower and a commercial office tower are the same engineering problem and completely different jobs to run. In strata the glass is in front of somebody's bedroom, so drops are scheduled with written notice, crews work on a published floor sequence so residents know which day affects them, and balcony access is negotiated lot by lot rather than assumed. Committees also expect the invoice to separate common property glazing from anything a lot owner is responsible for, which is a scoping question more than a cleaning one. Buildings on a broader common property programme normally fold this into their strata cleaning schedule.
Commercial towers are easier on access and harder on timing. Tenants sign leases that promise a presentable building, and the facade is the most visible part of that promise, so the programme usually runs on a fixed annual calendar agreed with the facilities manager and reported against. Internal glass is coordinated with the after-hours office cleaning round so the same building is not disturbed twice in a week. Portfolio owners running several assets at once tend to manage the whole thing through a single facilities management cleaning arrangement.
Mixed-use podiums sit awkwardly between the two. A retail base with a residential tower above means two stakeholders, two sets of trading hours and two tolerances for water on the ground. Shopfront glazing has to be done before the centre opens, the residential levels after a reasonable hour, and neither can happen while the other is under a drop. Getting that sequence right in the scope is what keeps a podium job to one mobilisation instead of three.
A useful high rise contractor tells you when washing will not help. Glass that has been sitting under a leaking planter or a poorly detailed spandrel joint develops mineral staining that has migrated into the surface, and no amount of detergent brings it back. Concrete slurry, render splash and welding spatter from a neighbouring site fuse to the pane. Scratches from a previous contractor using the wrong blade or working a dry pane are permanent. All of these are restoration or replacement decisions, and pricing a routine clean as though it will fix them wastes the building's money.
What we do instead is record the defective panes at the first clean, elevation by elevation, and hand the list back with the completion report so the owner can price restoration separately and track whether the damage is spreading. It also protects both parties: a pane that was already scratched before the first drop is documented as such.
The facade itself often needs more than the glass. Precast, painted render, aluminium cladding and stone all hold atmospheric grime that makes clean glass look worse by comparison, and that work belongs to a building facade cleaning scope run on a longer cycle. Hardstands, awnings and entry paving are separate again and usually pair with high pressure cleaning while the access equipment is already on site.
The sequence is the same on every building. A site assessment confirms the access method per elevation, the anchor and cradle documentation, the ground conditions and the trading hours that constrain the work. That produces a written scope with drop counts and a calendar. Before mobilisation the building receives the safe work method statement, the insurance certificates, the crew list and the tenant notice text so nothing has to be chased on the morning.
On the day the crew sets the exclusion zone first and the ropes second. Work runs top down so the elevation is not recontaminated, frames and sills are done with the glass rather than left, and each completed elevation is signed off before the rig moves. Weather is checked at height, not from the footpath, and a stood-down day is rescheduled rather than rushed.
Afterwards the building gets a completion report naming what was cleaned, what was stood down, the defective pane list and the next scheduled visit. Facades where the interior is being cleaned on the same programme are coordinated with the general window cleaning round so the tower reads clean inside and out on the same week.

There are three access methods and the building decides which one applies. A building maintenance unit, the roof-mounted cradle rig many Sydney towers already own, is used where one exists and has a current inspection record. Rope access, where technicians descend on twin ropes from certified roof anchors, suits buildings with no cradle or with facade geometry a cradle cannot reach. Swing stage or elevated work platform is used for lower and mid-rise facades and for setbacks and podium levels. On most buildings the final scope mixes two of the three, because no single method reaches every pane.
Two to four externals a year covers most Sydney commercial towers. Buildings within a few kilometres of the coast, from Barangaroo through Circular Quay to Bondi Junction, carry a salt film that dulls glass noticeably within a quarter and usually justify quarterly. Towers on arterial corridors such as Parramatta Road, Victoria Road and the Pacific Highway pick up brake dust and diesel particulate at a similar rate. Inland office parks in Norwest, Macquarie Park and Rhodes generally hold up on a half-yearly external cycle with internals done alongside the interior cleaning schedule.
Wind is the most common cause of a lost day. Suspended access and rope work have wind speed limits set in the safe work method statement and the rig manufacturer documentation, and crews stand down when the reading at height exceeds them regardless of what the weather looks like at street level. Lightning, heavy rain and extreme heat also stop work. Building side issues stop it too: an anchor point without a current test record, a cradle overdue for inspection, or a ground level exclusion zone that cannot be established because of a delivery dock or a pedestrian route that has not been managed.
Yes, and it is normally scheduled separately from the external drops. Internal glass is done after hours or on a floor-by-floor rotation coordinated with the tenants, because desks, monitors and cabling sit hard against the glass line and need to be worked around rather than moved. Atrium glazing, void balustrades and internal light wells are their own scope again and often need a boom lift or a rope descent inside the building. We map the internal and external programmes onto the same annual calendar so the whole facade reads clean at once.
A written scope for a Sydney high rise names the access method for each elevation, the number of drops or cradle runs, the pane count or glazed area, the frequency, the hours the work will run, and who is responsible for ground level exclusion zones and pedestrian traffic management. It also states what is excluded, which is usually anchor point testing, cradle servicing, glass restoration for scratched or stained panes, and any scaffolding. We provide the scope in writing after a site assessment rather than quoting from a photograph of the building.
Yes, and almost every Sydney tower we quote stays fully occupied through the programme. External drops run in the early morning and through the day with the floors below the working zone barricaded and spotted. Internal glass runs after hours. Retail podiums and food tenancies are done before opening so no water falls near an open shopfront. The building manager receives a drop schedule in advance so tenant notices, dock bookings and lift access can be organised without a scramble on the day.
