Most limestone cleaning enquiries from Bilgola Plateau start with mould and lichen on shaded render and paving, leaf-filled gutters on the gully edges, and salt haze on the ocean-facing glass of the eastern edge homes. On the hillside homes limestone and travertine are mostly pool coping and terraces that go grey and spotty; an acid-free clean and a poultice for the rust spots restore them.

1960s to 1980s brick and tile family homes on a high plateau, extensively rebuilt as rendered two-storey homes with pools, tennis courts and frameless glass taking ocean or Pittwater views from the edges. We work around Bilgola Plateau shops on Plateau Road, Hewitt Park and the Bilgola Bends below, on streets such as Plateau Road, Allen Avenue, Bilambee Avenue and Bilgola Terrace.

Field note from Bilgola Plateau. The Plateau's gully-edge homes on Allen Avenue and Lentara Road lose a surprising amount of roof capacity to bark in the valleys; we treat the September gutter clear as non-negotiable on those blocks. Nathan G, Founder

Our method in Bilgola Plateau

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!

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.
