What makes limestone cleaning different in Collaroy is sand-blasting and salt on the beachfront glass and render, rust streaks on every balustrade fixing, and green algae on the shaded south walls behind the dunes. Limestone and travertine pool surrounds near the ocean take salt and sunscreen as well as algae; we use an alkaline, acid-free clean and a poultice for rust and organic marks.

Beachfront homes and apartment blocks on Pittwater Road and Beach Road, famously exposed to east-coast lows, with Inter-war bungalows on the flat and larger homes climbing toward the plateau. We work around Collaroy Beach and the rock pool, Long Reef headland and golf course and Collaroy Plateau escarpment, on streets such as Pittwater Road, Beach Road, Anzac Avenue and Collaroy Street.

Field note from Collaroy. After an east-coast low the Collaroy beachfront glass carries sand as well as salt; we rinse before any pad touches it, or the sand scratches the glass. Local knowledge, and the reason we do not rush these jobs. Nathan G, Founder

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

In Collaroy we usually recommend limestone cleaning every 12 months, and the cycle is written on the quote.

Our method in Collaroy

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

Limestone dissolves in acid, so nothing acidic goes near it. We apply an alkaline cleaner to lift grime, a biocide for growth, and poultices left for up to 24 hours on organic and rust marks, then rinse with a wide fan below 800 psi. A penetrating sealer can follow once the stone is dry.

No acid under any circumstances
Low pressure only
Mortar and grout protected
Pool water shielded

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.
