Driveway & concrete sealing across the North Shore
Driveways on the North Shore are rarely flat or sunny. On the harbour side they pitch steeply down from the ridge roads to garages tucked under houses, and on the Upper North Shore they run long distances under trees. Both settings punish a surface. Leaf tannin from gums and jacarandas leaves brown stains, shade grows black algae and moss that turn slippery when wet, and oil and tyre marks sink into unsealed concrete. Rebuilt homes tend to have exposed aggregate or coloured concrete, older ones pavers and sandstone flagging, and each needs a different sealer and a different amount of preparation before it goes on.
A vetted tradie starts with a clean, usually a pressure wash with a surface cleaner, and that water carries detergent and sediment, so it is captured or directed onto garden rather than down the street gutter in line with NSW stormwater law. Then comes the choice: penetrating sealers that soak in and leave the look unchanged, or film-forming sealers that add sheen and deepen colour. On a steep driveway the tradie should talk about slip resistance, because a glossy sealer on a slope is a hazard, and additives exist for exactly that reason. Sandstone needs a breathable product so moisture can escape. Weather matters too: no sealing onto damp concrete, before rain or in heavy dew.
Describe the surface, its approximate size, the slope and whether it is shaded, and add photos of stains or flaking old sealer. Vetted sealing tradies working across the North Shore pick it up and come back with written quotes that set out preparation, product and coats. There is no charge to post a job and no obligation to go ahead with anyone. Shared driveways in strata schemes need the owners corporation's sign-off first, and in heritage conservation areas it is worth choosing a finish that does not change the look of sandstone or old paving from the street.

Frequently asked questions
It can be if the wrong product is used. Film-forming sealers add gloss, and on a slope that gloss becomes a hazard in rain. A vetted tradie should offer either a penetrating sealer or, if you want the film-forming look, an anti-slip additive in it, and explain the trade-off between look and grip before you choose.
Usually most of them. Tannin from gum and jacaranda leaves responds to a proper clean with the right solution before sealing. Very old stains may fade rather than vanish. Sealing afterwards makes the next round of leaves far easier to wash off.
The tradie will set this in the quote because it depends on the product, the temperature and the humidity on the day. Foot traffic is usually allowed well before vehicles. On a shaded Upper North Shore drive, curing can take longer than the label suggests.
Yes, with a breathable penetrating sealer chosen for sandstone. A product that forms a film on the surface can trap moisture and cause the stone to spall. On heritage properties, pick a finish that leaves the natural colour and texture unchanged, and check with council before anything that alters the street view.
