Commercial Window Cleaning Costs in Melbourne
What actually sets the number on a window cleaning quote, building type by building type, and how to read three quotes that look nothing like each other. Every job we price comes back as a fixed figure in writing.
- Fixednot hourly
- 24 hoursfor a written price
- Exclusionsnamed, not hidden
Commercial window cleaning cost is the hardest thing to publish honestly, because the same building can be quoted three ways and all three can be correct. A twelve storey office block might be cleaned from a building maintenance unit in two days, from ropes in three, or from a boom lift in five, and the price follows the method rather than the glass. So any page that puts one rate against one building type is guessing.
What this page does instead is show you the machinery behind the number. The four things that move every quote, how the access methods compare on real buildings, where a program beats a one-off, and how to compare three quotes that arrive in three different formats. By the end of it you should be able to look at a price and know whether it is cheap because the contractor is efficient or cheap because something has been left out.
We quote fixed prices rather than hourly rates, which puts the risk of a slow day on us rather than on you. Every quote names what is included, what is excluded and how many visits it covers. If you want the whole service explained rather than just the money, start at commercial window cleaning in Melbourne and come back here once you know which method your building needs.
One thing worth saying at the top. The cheapest quote in a set of three is usually cheapest for a reason, and the reason is rarely efficiency. Further down there is a section on exactly what gets stripped out to reach that number, written plainly, because a building manager who signs an uninsured contractor is the one carrying the consequence.
What is the real commercial window cleaning cost for a Melbourne building?
It is quoted per job, not per window, and the figure tracks the access method far more than the glass area. A shopfront is minutes of work. The same glass thirty storeys up is a day of rigging, which is why we price your building rather than publish a rate card.
| Building type | Priced by | What the figure assumes |
|---|---|---|
| Shopfront or single tenancy | Per visit | Street level, outside only, inside a round with neighbours |
| Office suite, internal glass | Per visit | Partitions, entry glass and meeting rooms, after hours if needed |
| Mid-rise facade to eight storeys | Per visit or per elevation | Pole or boom access, hardstand available for the machine |
| High rise facade | Per drop or per square metre | Rope or building maintenance unit, anchors certified and current |
| Strata apartment building | Per clean, per building | Common areas plus external glass, balcony access agreed |
| Factory or warehouse | Per visit, high glass separately | Floor access for a lift, or shutdown timing |
Read the units before you read the figure. A rate that looks high per visit can be low per year, and a low hourly rate means nothing if nobody will say how many hours the job takes. Fixed pricing exists to remove that ambiguity, which is why we use it even on buildings where an hourly rate would probably earn us more.
The units matter as much as the numbers. High rise work is usually priced per drop, which is one vertical line of glass from roof to ground, or per square metre of facade. Mid-rise is often per elevation, because the machine has to be repositioned for each face of the building. Retail and office interiors are priced per visit, since the work is measured in how long a person is on site rather than how much surface they cover.
That is also why square metre comparisons between buildings mislead. A tower with a thousand small punched windows costs more per square metre than a tower with a smooth curtain wall of the same area, because every frame, every seal and every transition is hand work. Panes, not area, is the honest measure, and it is the one we count when quoting a facade.
What are the four things that set the price?
Access method, glass area and pane count, how often we come, and what condition the glass is in. Access is the biggest by a wide margin, and it is the one nobody expects.
- Access methodWhether the glass is reached by hand, pole, platform, cradle or rope. This is the single largest variable and can double a quote on the same building.
- Glass area and panesHow much surface, split into how many pieces. A hundred small windows take longer than the same area in six large ones.
- FrequencyMaintained glass is faster than neglected glass, so the price per visit falls as the interval shortens.
- ConditionHard water staining, silicone residue, construction debris and years of neglect all add time to the first clean.
The four drivers do not carry equal weight, and it helps to know the order. Access can swing a quote by a factor of three. Pane count and condition usually move it by a third or so. Frequency changes the per visit figure rather than the total. If you only interrogate one line on a quote, make it the access method.
Access dominates because it is where the labour goes. On a high rise job, most of the day is rigging, checking, moving anchor lines and descending, and only a fraction is actually cleaning glass. Two buildings with identical glass area can differ by a factor of three simply because one has usable roof anchors and the other needs a cradle brought in.
Glass area matters in a simpler way, but only once access is settled. Two towers with the same footprint can carry very different amounts of glass depending on how much of the wall is solid, and a fully glazed building has more surface on every floor than a punched facade of the same height. That difference shows up as days on site rather than as a rate.
Pane count is the driver most people underestimate. Every pane has four edges, and edges are where water sits and where marks show. A heritage building on Flinders Lane with divided windows takes several times as long as a modern facade of the same size, which is why two buildings side by side can be quoted very differently.
Condition only bites once. Where a facade has gone untouched for years, the opening visit is about lifting bonded marks rather than rinsing away dirt, and we price it higher and explain the difference. Every visit after it costs less, which is the single strongest argument for putting a building on a schedule rather than calling when it looks bad.
On a tower, which is cheaper: rope, platform or scaffold?
Rope access almost always, on cost and on time. A rope crew needs no street closure, no machine hire and no build time, which is where the money goes on the other two methods.
A boom lift has to be transported, positioned, and given ground that can carry it. In the CBD that often means a permit, a traffic plan and a lane closure, and those costs arrive before anyone touches a window. Mobilisation can exceed the cleaning on a short job, which is why a small boom job sometimes costs more than a larger rope job on the same street.
Scaffold is worse again for window cleaning, because it is priced to be erected, hired by the week and dismantled. It makes sense when other trades are using it as well, and almost never when the only task is glass. If scaffold is already standing for a facade repair, cleaning the windows while it is there is genuinely cheap, and we will say so.
Timing pushes the same way. Permits and traffic plans are booked in advance and cannot be moved easily, so a boom job that loses a day to weather loses the permit with it. A rope crew blown off one morning comes back the next without anything being rebooked, which matters in a Melbourne spring when three usable days in a row is not guaranteed.
Rope access wins on the maths because the equipment arrives in a van. There is no hire clock, no street occupancy and no build. Two technicians can start within an hour of arriving and work any elevation without repositioning anything at ground level, which is why it suits repeat work better than any other method.
- Rope access: no hire, no permit, fastest to start.
- Building maintenance unit: cheapest where the building already has one.
- Boom lift: hire, float and often a permit before any glass is cleaned.
- Scaffold: only sensible when another trade is paying for it.
- The building decides, not the contractor's preference.
Where a building already has a cradle, that is usually the cheapest option of all, because the machine is on the roof and maintained by the owners corporation. The catch is availability and certification. A unit that is out of inspection cannot be used, and the cost of getting it recertified often lands on the same budget as the cleaning. How each method is actually worked is set out under high rise window cleaning, with the technique itself under rope access window cleaning.
Is a program cheaper than booking each clean?
Per visit, yes, and by a margin most buildings do not expect. Scheduled work is quicker because the glass never gets bad, the crew already knows the building, and the slot is already reserved.
The time difference is real rather than a discount. A facade cleaned four months ago needs washing. Leave the same facade two years and every pane has to be worked over before it will clear, the joinery cleared out and the ledges emptied, which can be double the hours for an identical finish.
There is also the setup cost, which is fixed no matter how dirty the building is. Rigging a roof, running lines, setting exclusion zones and doing the paperwork takes the same time whether the glass is filthy or nearly clean. Spreading that cost over more visits is what brings the per visit figure down.
Programs also remove the quoting cycle. Every one-off job needs an assessment, a quote, an approval and a booking, and that administration has a cost even when nobody invoices for it. A building on a calendar skips all of it, which is worth as much to a busy facility manager as the money.
Program costs, inclusions and terms all sit on the scheduled window cleaning programs page, down to the fact that rates hold for the term and nothing locks you in.
The same clean costs less per visit once the building is on a calendarHow do you compare three window cleaning quotes?
Put them side by side on scope rather than price. Most quotes that look different are actually describing different jobs, and the gap usually sits in access, inclusions and what happens when weather stops the work.
| Check | Why it matters | What a straight answer looks like |
|---|---|---|
| Access method named | Half the price sits here | Rope, cradle, boom or pole, stated for each elevation |
| Elevations included | Rear faces get quietly dropped | All four named, or the excluded one written down |
| Inside and out | Often assumed by one side only | Says which faces of the glass are covered |
| Frames, sills and tracks | Changes the finish completely | Included or excluded, in words |
| Public liability cover | You carry the risk if it is missing | Certificate of currency attached or offered |
| Method statement | Required for height work | Site specific, not a generic template |
| Weather policy | Wind stops rope work regularly | Rebooked at the same price, in writing |
| Number of visits | Annual totals hide the per visit rate | Visits and dates spelled out |
Run that list over three quotes and most of the price gap explains itself. The common pattern is that the cheapest quote covers three elevations, outside only, with frames excluded, while the dearest covers everything and says so. Once the scopes match, the real difference between contractors is usually far smaller than the first look suggested.
Watch for annual totals presented without a visit count. A quote reading one figure for the year tells you nothing until you know whether it buys two cleans or six, and two contractors quoting the same annual number can be a long way apart on the rate. Ask for the per visit figure and the schedule, then compare those instead.
Ask for the certificate of currency rather than accepting the word insured. It takes one email, it names the insurer and the expiry date, and it is the single document that matters most if something goes wrong at height. The wider list of what to check before appointing anyone is in our guide on how to choose a commercial window cleaner.
Why does the cheapest quote usually cost more?
Because the saving comes out of things you cannot see on the day: insurance, training, certified equipment and the time it takes to do a job properly. Those costs do not disappear, they just move to you.
Public liability cover is the obvious one. A contractor working at height above a public footpath without it is a risk the building owner ends up carrying, and the amount at stake dwarfs the difference between two quotes. It is worth checking even when the price looks normal, because plenty of quotes say insured without ever producing a document.
Then there is time. Glass can be made to look acceptable quickly and badly: skip the frames, leave the sills, run a squeegee across the middle of each pane and move on. It photographs fine and looks wrong within a fortnight, because everything that was left behind runs down the glass with the first rain.
Equipment is the quieter risk. Rope gear has a service life and a retirement date, anchors need certification, and platforms need current inspections. All of that is a running cost, and the quotes that ignore it are cheaper because someone decided the paperwork was optional.
Subcontracting is the last thing worth asking about. Some quotes are cheap because the company winning the work is not the company doing it, and the margin between the two comes out of the crew's time on your building. That is not automatically a problem, but you should know who is turning up and whose insurance covers them.
None of this means the dearest quote is the right one. It means the price has to be read next to the scope, and a contractor who cannot show insurance, a method statement and a straight answer about access is not actually cheaper.
- No certificate of currency means the risk sits with the building.
- Frames and sills excluded is the most common hidden cut.
- Rear elevations dropped because nobody looks at them from the street.
- Generic method statement with the building's name typed in.
- Variations later for work a fixed quote should have covered.
How do you get a fixed price?
Send the address, the number of storeys, roughly how the glass is reached and how often you want it done. Most buildings can be priced from that plus a look at the facade.
Anything above about eight storeys is worth a site visit, because anchors and roof access decide the method and the method decides the price. Either way the answer comes back in writing with the exclusions named. Start with get a quote.
- Fixed price, not an hourly rate that drifts.
- Written reply within 24 hours of the details arriving.
- Exclusions listed in the quote rather than discovered later.
- Insurance and method statements sent with the price, not on request.
