What Mosman balconies actually need

Mosman is mostly 1960s and 70s brick walk-ups through the Military Road corridor, alongside newer luxury blocks closer to Balmoral. The balustrades are typically rendered masonry with painted metal railings on the older blocks, frameless glass on anything built this century.

The recurring problem here is southern-aspect balconies that sit in shade most of the day and never fully dry through winter, so the floor tiles green up long before the north-facing ones do.

a lot of Mosman blocks are three-storey walk-ups with no lift, so gear has to come up stairs and there is no service corridor to work from, which is why a self-contained system matters more in Mosman than the marketing usually admits.

Every balcony clean covers everything

Floors

Tiles, stone or concrete cleaned and the grout lines treated, not just rinsed over.

Glass & sliding doors

Balustrade glass and doors cleaned, then blade-finished so they are clear rather than smeared.

Walls & ceilings

Soft washed at low pressure and pre-treated for mould and algae, so growth is killed rather than wiped off.

Frames & tracks

Door tracks, frames and drainage points cleared out, which is where the grit and growth actually sit.

Balustrades

Original render and metalwork treated appropriately for their age.

Strata-compliant

$20M public liability, certificate of currency with every quote, and no runoff for building management to manage.

Why water recovery matters in Mosman

We are the only Sydney balcony service running the Mosmatic Venturi water recovery system.

The reason balcony cleaning gets refused in apartment buildings is almost never the cleaning. It is the water. Runoff goes over the slab edge onto the balcony below, down the facade, or into the car park, and the building ends up with a complaint instead of a clean balcony.

Our system captures the water at the head as we work. Nothing leaves your balcony. That is what makes it workable in dense blocks where your balcony overhangs someone else’s.

Frequently asked questions

Do you clean balconies in older Mosman walk-ups with no lift?

Yes. A large share of the blocks off Military Road are three-storey walk-ups. Our equipment is carried in, and the water recovery unit means we are not running hoses down a stairwell or leaving water anywhere it should not be.

My balcony faces south and the tiles have gone green. Can that come back?

Almost always. Green on a shaded Mosman balcony is algae sitting on the surface, not staining through it. It is soft washed and pre-treated rather than blasted, which lifts the growth without driving water into the grout or the membrane below.

How much does a balcony clean cost?

Standard balconies start at $295. The price depends on the size of the balcony, the surfaces involved and how much glass there is. Strata buildings doing multiple balconies together get bulk pricing. You get a written quote within 24 hours, agreed before we start, not an hourly rate that moves.

How long does a balcony take?

Most single balconies are done in two to three hours. A larger balcony with a lot of glass and stone can run longer. We work to the result, not the clock, and the quote is fixed either way.

Do I need to be home?

Only if access requires it. If the building or your neighbour can let us in, you do not need to take time off. We will confirm what we need when we quote.

Do you do whole buildings, not just single balconies?

Yes, and that is where it makes the most sense. Doing every balcony in a building in one visit is significantly cheaper per balcony than doing them one at a time, and it means the building presents consistently. We quote strata buildings at a set monthly price and can put it on a 12-month service agreement with locked pricing if the committee prefers a predictable number.

Are you insured?

Yes. $20M public liability. ABN 45 984 876 899. We provide the certificate of currency with every strata quote as a matter of course.
