Specialist exterior building cleaning across Sydney CBD, North Sydney, and Parramatta. Rope access certified technicians, pressure washing, and glass curtain wall specialists. Annual programs and one-off restorations. Free quotes within 24 hours.

Pro Clean Corp delivers professional building facade and exterior cleaning services across Sydney, restoring commercial towers, retail buildings, and strata complexes to their original appearance with specialist high-rise cleaning techniques. Sydney's urban environment subjects building exteriors to traffic pollution, salt air, biological growth, and graffiti that accumulates year-round and degrades both appearance and material integrity.
Our rope access certified technicians, elevated work platform operators, and pressure washing specialists safely clean glass curtain walls, cladding, brickwork, concrete, and architectural features at any height. We are $20M insured, police-checked, and have served 1,200+ clients across Sydney CBD, North Sydney, Parramatta, and all high-rise precincts. We offer one-off facade restorations as well as annual maintenance programs with no lock-in contracts.
Safe, cost-effective high-rise facade access without expensive scaffold installation.
Pure-water-fed pole systems and abseiling for streak-free glass facade results.
Surface-specific solvents that eliminate graffiti from brick, concrete, cladding, and glass.
Structured programs to maintain building presentation and prevent long-term material degradation.

The method is chosen by the building, not by the contractor's preference. Height, anchor provision, street frontage, pedestrian exposure, the substrate and the tenancy hours between them narrow the options to one or two. On most Sydney commercial buildings we end up combining two — abseil for the tower face, a boom for the podium and awnings.
Rope access is the fastest way onto a tall, uninterrupted face when the roof already has certified anchor points and a documented anchor register. Technicians descend on a working line with an independent back-up line, so there is no single point of failure, and they can stop anywhere on the drop to work a stubborn area rather than repositioning a machine. It is quiet, it needs almost no ground footprint, and it leaves the loading dock and car park free — which is often the deciding factor in a CBD tower where the alternative is closing a lane. The constraints are real though: the anchors must be current and certified, wind stops the work well before it stops a boom, and a facade with deep vertical fins or projecting sunshades can be genuinely awkward to reach on rope.
An elevated work platform suits low and mid-rise buildings, podium levels, awnings, signage bands and any facade where operators need to carry equipment — a pressure unit, a soft wash lance, restoration chemicals — rather than just a bottle and a squeegee. Knuckle booms reach over landscaping and around parapets that a straight boom cannot. The trade-offs are ground-side: you need hardstand capable of taking the outrigger loads, a traffic and pedestrian management arrangement if the machine sits on a footpath or in a carriageway, and often a council permit for a road occupancy. All operators hold the relevant high risk work licence for the platform class, and the machine's log book and pre-start records travel with the job.
High pressure is the wrong first answer on most facades. Biological growth, atmospheric grime and the black streaking that runs from sills and copings are chemical problems, not force problems, and the pressure needed to blast them off render, aged sandstone or a painted surface is also the pressure that erodes the surface, drives water past sealant joints and voids coating warranties. Soft washing applies a dwell-time chemistry at low pressure, lets it work, then rinses — it removes the organism rather than the top millimetre of substrate, and it stays clean for longer because the growth is killed rather than knocked off. High pressure still has a place: concrete carparks, loading docks, hardstand, unpainted precast and heavy carbon deposits on non-porous surfaces. The judgement call is made surface by surface, and it is worth asking any contractor which one they intend to use and why before they arrive with the machine.
Routine glass cleaning is either pure-water-fed pole from ground level for the lower floors or abseil above that, using deionised water that dries without spotting so no drying pass is needed. Restoration is a different job. Glass that has been rained on through a construction phase, sat under a leaking coping, or been exposed to run-off from concrete or steel picks up mineral staining and corrosion etching that no detergent will touch; that is treated with a cerium-based or acid restoration system, tested on an inconspicuous pane first, and it will not save glass where the etching has gone through the surface. Curtain wall work also means respecting the gaskets and structural silicone joints, keeping solvents off the sealant, and cleaning the frame and pressure plate rather than only the vision panel. Buildings with a dedicated window cleaning schedule rarely need restoration at all.
Substrate dictates both the chemistry and the pressure. A test patch is done on every building before the main clean begins, and on heritage or coated surfaces it is photographed and signed off with the building owner first.
Deionised water systems for routine cleaning; restoration chemistry only where mineral staining or run-off etching is present. Gaskets and structural silicone kept clear of solvents.
Tolerant of higher pressure where unpainted, but porous enough to hold biological growth deep in the surface — soft wash first so it does not return within a season.
Low pressure and near-neutral chemistry only. Acid and aggressive pressure open the grain, accelerate salt attack and permanently change the colour. Common on Sydney heritage frontages.
Neutral pH detergent, soft brushes and rinsing in panel runs. Alkaline products dull the coil coating and streaking on ACP is very hard to correct once it starts.
Soft washing with a controlled dwell. High pressure blows out the render at control joints and around penetrations, and the repair costs more than the clean.
Efflorescence, mortar smear and lichen respond to targeted treatment rather than blanket pressure. Mortar joints are checked for erosion before any pressure is applied.
Facade cleaning is work at height, which under the NSW Work Health and Safety Regulation 2017 is high risk construction work — and that carries obligations for the building owner and the strata committee, not only for the contractor. A Safe Work Method Statement must be prepared before the work starts, must be specific to your building rather than a generic template with the address changed, and must be available on site for the duration. Ours covers the access method, fall arrest and rescue arrangements, exclusion zones, chemical handling and the emergency response, and it is issued for review before mobilisation rather than produced on the day.
Three things are worth confirming in writing on any facade quote. First, anchor points: roof anchors and static lines require periodic certification, and if your building's register is out of date that has to be resolved before rope access can proceed — a contractor willing to abseil off uncertified anchors is telling you something about the rest of their work. Second, the ground: pedestrian exclusion zones, spotters, overhead protection and a traffic management plan where a footpath or lane is affected, plus any council permit. Third, cover: we carry $20M public liability, all staff hold current National Police Clearances, and certificates of currency go to the building manager or strata manager before the first visit rather than on request afterwards.
Water capture and run-off matter too. Chemistry rinsed off a facade reaches the stormwater system unless it is contained, so wash water is managed to the requirements of the site — bunding and collection at ground level where the building drains to a street pit, and neutral-pH products selected wherever containment is not practical. Strata committees receive a completion report with the SWMS, the products used and dated photographs, which is the document that ends up in the minutes. See also strata cleaning Sydney for the common-area programme that usually sits alongside a facade schedule.
We use a combination of rope access techniques, elevated work platforms (EWPs), and extended water-fed pole systems depending on building height, architecture, and access constraints. All work at height is performed under a documented Safe Work Method Statement with appropriate fall arrest systems and pedestrian exclusion zones in compliance with NSW WHS Regulations.
We clean all commercial facade types including glass curtain walls, aluminium composite cladding (ACP), precast concrete, face brick, rendered surfaces, terracotta, sandstone, and painted masonry. Our technicians select appropriate cleaning methods and products for each specific material to ensure effective cleaning without surface damage.
Yes. We provide professional graffiti removal from all exterior building surfaces including brick, concrete, painted walls, cladding, and glass. We use surface-specific solvent and anti-graffiti systems that fully remove vandalism without damaging the underlying substrate. Anti-graffiti protective coatings can also be applied after removal.
For most Sydney CBD and inner-city buildings, we recommend annual facade cleaning to address atmospheric pollution and biological growth before it causes material degradation. Buildings adjacent to heavily trafficked roads, near water, or in industrial areas may benefit from bi-annual cleaning. We offer annual maintenance programs with scheduled visits and priority response.
Yes. We work regularly with strata managers and body corporate committees to deliver facade cleaning for residential and mixed-use strata buildings across Sydney. We provide detailed quotes, SWMS documentation, insurance certificates, and completion reports suitable for strata committee records and AGM presentations. Call 1300 494 983 to discuss your building.
