Sealing earns its keep on the ocean front where salt attacks concrete, on lagoon-side slabs in Narrabeen that stay damp, and on steep, mossy driveways in Seaforth and Beacon Hill where grip matters.

The Northern Beaches packs surf beaches, four coastal lagoons, the Pittwater estuary, Middle Harbour and national park bushland into one council area, so concrete sealing is never one method for everyone. The table shows how we adjust it by condition and how often it is usually needed.

Conditions Suburbs What we are dealing with How often
Ocean-front and first-ridge Manly, Queenscliff, Freshwater, Curl Curl, North Curl Curl and Collaroy and 6 more Salt film on glass within a fortnight, rust-run from every fixing, and black cyanobacteria on the shaded south and east walls; sealing keeps it out of the surface re-seal every 3 to 4 years
Lagoon and estuary Dee Why, Narrabeen, North Narrabeen and Warriewood Green algae and black mould on the shaded elevations, lichen on stone and pavers, and moss in any joint that stays damp; sealing keeps it out of the surface re-seal every 3 to 5 years
Pittwater waterfront and slopes Bayview, Church Point and Clareville Tannin and leaf-litter staining, lichen and moss on sandstone, green film on timber and pool surrounds, and mould under deep eaves; sealing keeps it out of the surface re-seal every 3 to 5 years
Plateau and bushland edge Elanora Heights, Ingleside, Terrey Hills, Duffys Forest, Belrose and Davidson and 3 more Gutters full of eucalypt leaf and bark, moss and lichen on shaded roofs, paving and tennis courts, and red clay staining on concrete after storms; sealing keeps it out of the surface re-seal every 5 to 7 years
Harbourside Middle Harbour Fairlight, Balgowlah Heights, Clontarf, Seaforth and North Balgowlah Mould and algae on render and painted brick, lichen on sandstone retaining walls, and tannin staining from the tree canopy over paths and driveways; sealing keeps it out of the surface re-seal every 4 to 6 years
Hillside and village Balgowlah, Cromer, Beacon Hill, Allambie Heights, Collaroy Plateau and Bilgola Plateau Salt haze on glass that faces the ocean, mould on the shaded render, and dull, lichen-spotted concrete driveways and paths; sealing keeps it out of the surface re-seal every 4 to 6 years

Our method in the Northern Beaches

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

The slab is cleaned and dried for two days, moisture-tested, and sealed with a penetrating silane or siloxane for a natural look or a film sealer for colour and sheen. Edges are cut in by brush and the sealer is rolled or sprayed evenly.

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 · 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.
