Two things drive the work out here. Salt and damp sea air keep surfaces from drying out properly, so paths, courtyards and driveways in shaded terrace laneways grow moss and algae faster than they would inland. And a lot of the surfaces themselves are old sandstone, tessellated tile or heritage brick, which will not take the same pressure as a modern concrete driveway. Getting a surface clean matters less than getting it clean without damaging it, and on this side of the city the second part is where the judgement is.
Two things decide how fast growth comes back on an Eastern Suburbs roof: how much sun that face gets, and how close you are to the water.
Salt haze off the beach settles on everything and leaves a film that rain does not rinse away. Algae feeds on it, so the black streaking shows up first on the southern and eastern faces, where the roof stays damp longest. On the sunny north face the same roof can look almost clean.
A lot of the older stock here is terracotta that has lost its glaze on the weather side. Once the glaze has gone the tile is porous, and lichen anchors into the surface rather than sitting on top of it. That is the point where pressure stops being the answer: blasting an unglazed terracotta tile takes the face of the tile along with the lichen. These roofs get treated first and then soft washed.
Sandstone is the other Eastern Suburbs surface that needs restraint. Heritage paving and sandstone walls are soft, and they get a fraction of what a concrete driveway gets.
We look at what the surface actually is before deciding on pressure. Sandstone, heritage brick and old tessellated tile all behave differently.
Not every surface should be pressure cleaned. If a lower-pressure method is the right call for your paving, we will tell you.
Garden beds, painted surfaces, windows and neighbouring property are protected before we start.
Moss, algae, lichen and general grime are removed from the surface rather than just wetted down.
We think about where the water and material go, which matters on terraces where paving drains straight into a shared area.
We go over the finished surface with you before we pack up.

We look at the surfaces, and give you a price before any work starts.
We protect the surrounding areas, clean the surfaces, and tidy up before we leave.
Older sandstone and heritage paving need care, and full pressure will damage them. We assess the surface first and adjust the method, and if pressure cleaning is not the right approach for that material we will say so rather than take the risk.
Not always. High pressure on a tiled or aged roof can drive water under the tiles and strip surface coating, so it is not something we apply by default. We look at the roof first and recommend the method that suits it.
Shade and salt air. Courtyards and laneway paving through the Eastern Suburbs often stay damp, and damp plus low light is what moss and algae need. Cleaning removes it, but a surface that never gets sun will regrow faster than one that dries out.
If a path or courtyard has gone green and slippery, it is worth sorting before someone slips. Call our Bondi Beach team on 0452 223 327 or send the form for a free quote.

Australian standards and Code requirements we work to, with the source for each.
Observatory Hill has averaged around 1,213 mm of rain a year on records kept since 1858. Everything on the roof, from panels and skylights to gutters, has to keep working through that volume of water and the grit it carries off the surface.
NSW work health and safety law requires a safe work method statement for construction work where a person could fall more than two metres. Single-storey gutter and roof work clears that line, which is why the job is planned, harnessed or edge-protected before anyone gets on the roof.

SafeWork NSW reports that most serious and fatal falls happen from roofs, ladders and building edges at four metres or under, and a fall from two metres can kill. A single-storey Sydney house is squarely inside that range.

Pressure cleaning in the Eastern Suburbs has its own rules: heritage areas, salt air and tight access all change how the job is done. Everything below links to the council or standard it comes from, so you can check it yourself.
The National Construction Code puts a home within 100m of breaking surf in the harshest corrosion category. Between 100m and 200m an AZ200 or AM150 coating is required, and only past 1km does the standard category apply. That changes fixings, flashings, gutters and downpipes.

The roof finish is often the most visible part of the building.

Roofs in the Eastern Suburbs corrode faster because many streets sit close to breaking surf, and salt attacks steel sheeting, fixings, flashings and gutters. The National Construction Code puts a home within 100m of breaking surf in the harshest corrosion category, requires an AZ200 or AM150 coating between 100m and 200m, and only applies the standard category beyond 1km.
In the Eastern Suburbs it depends on the council and on whether the house sits in a heritage conservation area. Waverley Council lists 17 heritage conservation areas, including Bondi Beach, Charing Cross and Queens Park, where roof material and colour are assessed and most external work needs consent. Woollahra Council’s DCP does not permit concrete roof tiles in the Paddington conservation area, and Randwick treats repainting an already painted surface as maintenance that does not need consent.
Not on every roof plane in the Paddington conservation area: Woollahra Council does not allow skylights on the front or side roof planes there, caps any skylight on the main roof at 1.5 square metres and limits rear planes to 25 per cent transparent material.
