Travertine Sealing in Upper North Shore

Travertine is the default pool-surround stone from Vaucluse to Palm Beach and it has one flaw: the holes. Algae, sunscreen and pool chemicals collect in the pits and the stone turns green and slick. Pressure washing opens the holes further. We clean travertine at low pressure with a biocide, fill or leave the holes as the client prefers, and seal with a breathable impregnator that keeps water and chemistry out of the pits.

Travertine Sealing across Upper North Shore

The Upper North Shore's large blocks, long driveways and tall trees make it the moss and leaf-litter capital of Sydney. We clean, treat and seal more driveways and tennis courts here than anywhere else. For travertine sealing specifically, the surfaces we meet most in Upper North Shore are driveways, gutters, long driveways, pool decks, pool surrounds, render. Travertine is cleaned with a hypochlorite biocide at low pressure and a soft brush, so the growth in the pits dies without the stone being eroded.

Ku-ring-gai Council. Ku-ring-gai Council is one of Sydney's greenest LGAs, with heavy tree canopy across Wahroonga, Pymble, Killara and St Ives. Roofs, gutters and driveways accumulate leaf litter, lichen and black algae quickly, and large blocks mean long driveways and tennis courts that benefit from professional cleaning and sealing. Many properties sit in bushfire-prone areas where gutter and roof debris removal is a safety task, not just an aesthetic one.

Hornsby Shire Council. Hornsby Shire Council is known as the Bushland Shire. Suburbs like Beecroft, Cherrybrook and West Pennant Hills carry dense canopy, so gutters, roofs and shaded driveways need regular debris removal and moss treatment, and many properties are designated bushfire-prone.

Suburbs we service for travertine sealing in Upper North Shore: Wahroonga, Pymble, Killara, Lindfield, Gordon, Turramurra, Warrawee, St Ives, Roseville.

Our method

How we clean it, and how we protect everything around it

Travertine is cleaned with a hypochlorite biocide at low pressure and a soft brush, so the growth in the pits dies without the stone being eroded. Stains are poulticed. If the client wants the holes filled, we grout them with a colour-matched filler and let it cure. After 48 dry hours and a moisture test, a penetrating sealer is applied in two wet-on-wet coats and residue removed before it hazes. We avoid gloss topical sealers on pool surrounds because they peel in chlorinated water and become slippery.

Pool water, skimmer and filter protected from debris and chemistry
Glass fencing and render masked
Sealing deferred in rain or extreme heat
Furniture lifted off the surface during the work

What clients say

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.
