What makes sandstone cleaning different in Mona Vale is salt and rust on the headland homes, black growth on the south elevations of the strata blocks, and oil and algae on commercial and medical-precinct car parks. 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.

Headland homes on Surfview Road and Golf Avenue with the full ocean exposure, Inter-war and post-war homes across the village grid, and a growing stock of medium-density strata around Pittwater Road and Mona Vale Hospital. We work around Mona Vale Beach and the Basin rock pool, Mona Vale Headland and the golf course and Pittwater Place and the village, on streets such as Surfview Road, Golf Avenue, Bassett Street and Darley Street.

Field note from Mona Vale. Surfview Road is the first thing the southerly hits north of Long Reef; the homes there lose their glass clarity in ten days, and the ones on a six-week program look like different houses to the ones that call once a year. Nathan G, Founder

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

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

Our method in Mona Vale

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!

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.
