Render, brick and cladding each react differently to water, so we plan the clean around the wall surface rather than one setting for the whole building. On homes, strata blocks and commercial frontages, a low-pressure soft wash with specialised solutions clears black mould, green growth, sill streaks and street grime while render, paint and mortar stay as they were. It suits walls due for a repaint, a sale, a new lease or a strata maintenance round.
In September 2026 we carried out a house wash on this rendered two-storey home with a double garage in Leichhardt. Grey streaking and mould had settled across the rendered gables, and both were lifted.
Cement and acrylic render is porous and textured, so algae and dirt sit inside it; a solution that soaks in cleans it far better than a jet that scours the top. Bagged and painted brick keep their coating when the rinse stays gentle, and face brick is washed without wearing back the mortar joints. Fibre-cement and weatherboard-look cladding have laps and joins that water should never be driven into. Metal, aluminium and composite panels are rinsed with the seams and sealant in mind, and painted masonry facades on older shops and offices get the same patient approach.

The marks on a facade depend a lot on which way it faces. Shaded and south-facing walls grow black mould and algae, the base of a wall turns green where splashback keeps it damp, and dirty streaks run down from sills, ledges and parapets every time it rains. Street-facing walls collect traffic grime and soot, and buildings near the coast carry a film of salt. A high-pressure jet can etch render, push water in behind cladding and peel paint, so our crew keeps the pressure low and lets the solution loosen the build-up. Cleaning will not mend cracked render or bring back faded paint, but it does show clearly what needs repair before a painter starts, an agent lists the property or a strata committee plans its next round of maintenance.

What owners, strata managers and building managers ask us before booking a clean of render, brick or cladding.
Sound render and paint come through a low-pressure wash unharmed, because the specialised solution breaks down the growth and the rinse only carries it off. Damage usually starts when someone uses a narrow, high-pressure jet close to the wall. If a coating is already chalky or lifting, show us at the quote so we can plan around it.
Yes. Cladding boards and panels overlap or meet at joins, so we apply and rinse working with the direction of those laps instead of spraying up into them. Keeping the pressure low is what stops water being pushed into the wall cavity, where it can do real harm.
It is worth doing. Paint grips poorly over mould, algae and grime, and painters generally want a clean, dry surface to work on. Ask your painter how long they want the walls left to dry, and book the clean with enough time before their start date.
We do. As well as family homes, we clean apartment blocks, townhouse complexes, shopfronts and office buildings. If your strata committee or property manager works to a planned maintenance schedule, we can quote the facade clean to fit it.
Sometimes, and only partly. Efflorescence is salt carried out of masonry by moisture, and rust marks come from metal fixings or water running off them, so neither is the organic growth a soft wash is built for. We look at them at the quote and give you an honest view of whether cleaning will help. If moisture keeps feeding them, they tend to return until that is fixed.
Not necessarily. What we need is access to every wall, so leave side gates unlocked, close the windows and keep pets inside. It helps if someone can walk round with the crew at the end, but a phone call and the before-and-after photos also work.
Yes. Ultimate Exterior Clean holds $10 million public liability cover, and team members are certified to work safely at heights, which matters on upper-storey walls, gables and parapets.
No, and we would rather say so up front. A wash removes what is sitting on the wall; it does not fill cracks, reattach drummy render or restore colour that the sun has bleached out. What it does give you is a clear look at those faults so a renderer or painter can quote accurately.

Dust and grime settle on flat ledges, then rain washes them down the wall in narrow trails. Over time those trails darken and can hold mould. A soft wash usually lifts them well, though the ledges will keep collecting dirt between cleans.
Our products are biodegradable and eco-friendly, and they are safe around gardens, pets and children. We are happy to send product details with the quote if your building or business has rules about chemicals on site.
Yes. Aluminium, steel and composite panels are common on newer apartments and commercial buildings, and they mark easily with traffic film and salt. We rinse them gently and keep water away from the sealed joints between panels.
Yes. Every job comes with before-and-after photos, which are handy to file with strata or property maintenance records.
