Concrete Sealing in Upper North Shore

Sealed concrete stays clean three times longer and never develops the deep oil stains that ruin a driveway. We clean, moisture-test and apply the right sealer for the finish: penetrating for a natural look, acrylic for wet-look colour, or polyurethane for traffic areas.

Concrete 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 concrete sealing specifically, the surfaces we meet most in Upper North Shore are driveways, gutters, long driveways, pool decks, pool surrounds, render. Concrete is cleaned, allowed to dry to below 5 percent moisture and tested.

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 concrete 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

Concrete is cleaned, allowed to dry to below 5 percent moisture and tested. Penetrating silane-siloxane sealers are sprayed and back-rolled; acrylic and polyurethane sealers are rolled in two thin coats with a slip additive where required around pools. The surface is closed to traffic for 24 hours.

Moisture test prevents cloudy sealer failure
Slip additive on pool and wet areas
Masking of adjoining stone and garden
Weather window checked 48 hours ahead

Google review · Pressure 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.
