Every December, the same thing happens on Sydney buildings. The glass gets squeezed in on the 23rd. The facade slips to January. Someone decides the gutters can wait until after the break.
Then the site sits empty for close to two weeks in the hottest, highest UV part of the year, with everything that was left on the glass quietly baking in the sun.
This is not a cleaning article. It is a deadline article. Christmas cleaning in Sydney has a cut-off point that arrives well before Christmas itself, and most buildings work to the wrong date.
The building closes on 24 December. External trade work on it stops earlier than that, and the gap between the two is where most December plans fall apart.
Access work runs in blocks, not in slots. Rope access crews, elevated work platforms and building maintenance units are committed to consecutive days across multiple sites. Once a building is inside a crew’s December run, it is inside it. What does not happen is a new job being bolted on between the last full working week before Christmas and the first week of January, because by then the crews are off, the inductions are closed and the gear is booked elsewhere.
That is the practical deadline. Not 24 December. The point where your building is already committed to a schedule or already left out of one.
Based on how the month runs across Sydney commercial and strata sites, the shape of it is fairly predictable.
| Window | What is happening | What it means for you |
|---|---|---|
| Early December | Last realistic point to add a new job to a December schedule | Book now or plan for January |
| Mid December | Crews at full capacity on pre-booked work | Only committed jobs get done |
| 24 to 26 December | Sites closed, no access, no inductions | Nothing moves |
| 27 Dec to 1 January | Skeleton staffing, emergency response only | Problems get worse, unattended |
| From 4 January | First full working week of 2027 | Every postponed job lands at once |
Windows shown are the typical pattern across Sydney sites rather than fixed industry dates. Weather, site access and individual building rules all shift them.
If you manage the building, this is the list that should be signed off before the last person leaves.
Most of that work sits under a commercial window cleaning scope. Render and painted surfaces should be handled by soft washing, never high pressure.
Here is the part that turns a cleaning job into a capital expense.
January is the hottest month in Sydney, with a mean maximum of 26.0 degrees Celsius and a record high of 45.8. UV sits in the extreme range for much of it. Any mineral deposit left on glass when the building empties gets hit by both at once, and instead of sitting on the surface it bonds to it.
Bonded mineral deposits become hard water etching. Etching is permanent. There is no chemical or pad that brings etched glass back, only replacement.
The same window does three other things at once:
None of it gets rinsed, because there is nobody on site to notice. Three quiet weeks in January is not a neutral period. It is the period when the cheapest problem to fix becomes the most expensive one.
Solar is worth separating out. Dust, pollen and ash cut output, and bird droppings are worse because a shaded cell drags down the cells around it in the same string. Our solar panel washing service uses deionised water so nothing is left behind to attract the next layer.
It looks cheaper, because January is quieter on paper. In practice it costs more, for two reasons.
Capacity is tighter, not looser. Every job postponed out of December lands in the same fortnight. The buildings that booked early get the good slots. The ones that waited take what is left.
Remediation is not a clean. If glass has etched over the break, you are no longer buying a clean. You are buying glass replacement, and that conversation is an order of magnitude different from the one you would have had in November.
We are not going to pretend a rush job is better than a scheduled one. A crew pushing to finish before the 24th, on hot glass, in direct sun, is how you get streaks and rework. If December has gone, January is the right answer.
If you are fitting this into a single day before the break, the briefing matters more than the cleaning.
For how access lead times run on larger buildings, the guide to scheduling high-rise window and facade work covers it in more detail.
Then book the second week of January, and leave December alone.
The buildings that panic-book the last week before Christmas usually end up paying for it twice: once for the rushed clean, and again for the rework after the streaks show up in January light. A properly scheduled clean in the second week of January, before the peak heat really settles in, will look better and last longer than anything squeezed in on the 23rd.
The only exception is entry and lobby glass. That is quick, it does not need access equipment, and it is the thing every tenant and visitor sees first. If you can only do one thing, do that one.
Some do, on skeleton crews, but capacity is limited and it is usually reserved for contracted buildings and emergency work. Access equipment is generally not available for new bookings in that week. Plan as if the industry is closed from 24 December to 4 January, because in practical terms it mostly is.
Earlier than the committee meeting that approves it. By early December the December schedule is usually committed, so the realistic answer is that a December booking should be made before December. If your next committee meeting is in late November, that meeting is the last useful one for the year.
Yes, early in the morning. Cleaning solution flashes dry in direct sun and leaves streaks, and cold water on glass that has been in the sun all afternoon creates thermal stress. Our crews start at first light in summer for exactly this reason.
Because the damage is cumulative and invisible until it is not. Mineral deposits bond under UV, dust and ash bake into a film, and salt crystallises. None of it looks dramatic in week one. By March it is a restoration job rather than a clean.
For a commercial or strata site, typically entry and lobby glass, external glass and frames, facade and render, balustrades, car park and bin bay concrete, signage, and solar panels. Balcony drainage staining and condenser runoff are usually quoted as extras because they are surface-specific.
Before. January is peak generation month, so soiling during January costs you the output you were counting on. Cleaning in early December means the panels are working at full capacity through the period that actually matters.
We clean commercial and residential windows, facades and solar panels across Greater Sydney. If your building needs to be sorted before the shutdown, talk to us now rather than in the last week of December.
