What makes sandstone cleaning different in Avalon Beach is salt and black growth on the headland homes' render and glass, moss and lichen on sandstone and timber in the shaded Careel Bay pockets, and mould on the village strata. Near the surf sandstone holds salt in its pores, which crystallises and powders the surface; we clean with biocide and low pressure, rinse thoroughly to flush the salt, and never use acid.

Mid-century modern and contemporary homes on the Bangalley and north Avalon headlands, Inter-war weekenders on the flat behind the village, and Careel Bay waterfront homes on the Pittwater side, with low-rise strata in the village. We work around Avalon Beach and the rock pool, Avalon village on Old Barrenjoey Road and Bangalley Head, on streets such as Barrenjoey Road, Old Barrenjoey Road, Bellevue Avenue and Marine Parade.

Field note from Avalon Beach. Avalon's mid-century houses on the headlands use off-form concrete, sandstone and timber that pressure washing would ruin; we treat them as conservation jobs, with test patches and the lowest effective pressure. Nathan G, Founder

Run-off in Avalon Beach. This part of the peninsula drains to Avalon Beach and Careel Bay. On every Avalon Beach sandstone cleaning job the kerb inlets are bunded and rinse water is captured or sent to garden, as Northern Beaches Council requires.

In Avalon Beach we usually recommend sandstone cleaning every 12 to 18 months, and the cycle is written on the quote.

Protecting the garden and drains during sandstone cleaning in Avalon Beach
Our method in Avalon Beach

How we do it, and what we protect while we work

Each wall or flight gets a test patch first. A quaternary ammonium biocide is laid on and kept wet for 20 to 30 minutes, the dead growth is brushed off with stiff nylon brushes, and the stone is rinsed with a wide fan under 500 psi held well back. Iron bleed and leaf tannin get a reducing poultice instead of acid.

Pressure capped at 500 psi on all sandstone
Lime mortar joints protected
Carved detail brushed by hand
Heritage documentation on request

Highly recommend The Prestige Standard, they cleaned my sandstone, it looks perfect!

Caspar Howard
Google review · Sandstone Cleaning

I recently had my brick pavers cleaned by Prestige Standard and I couldn't be happier with the results. The team was professional, punctual, and paid great attention to detail. My pavers went from looking dull and stained to fresh and almost brand new again.
