Driveway sealing in Newport
Newport driveways are a slope problem first. Hillside homes above the beach and on the Pittwater side have long, steep concrete and exposed aggregate drives, some shared between neighbours, and the sections under tree cover stay green and slick for most of winter. Salt reaches the lower drives and leaves efflorescence on concrete and pavers, and on waterfront blocks tyres bring in sand and grit. Coloured concrete fades on the open, north-facing sections and holds its colour in the shade, which looks patchy. Sandstone paving and steps between levels take on tannin stains from leaf litter and lichen where damp.
A vetted tradie pressure cleans the surface, treats moss and algae with a biocide so it does not return within weeks, lifts oil and tannin stains, and lets the slab dry before sealing. On steep sections the sealer choice matters: a sealer with grit added, or a penetrating product that leaves no glaze, keeps the drive safe in the wet. Coloured concrete gets a colour-enhancing acrylic, exposed aggregate and pavers a product suited to the stone, sandstone a breathable impregnator. Wash water on a slope wants to run straight into the gutter, so the tradie bunds the kerb and diverts it onto garden to comply with state pollution law.
Post the job with a photo taken from the street and another from the garage, an idea of its length, the surface type and whether it is shared, and the job is matched with vetted tradies who regularly seal driveways on the peninsula. They get in touch directly with a written quote, free to you, and nothing obliges you to accept. The quote should set out the cleaning, any crack or spall repairs, the sealer and its finish, how many coats, how long cars must stay off, and how run-off is controlled. If the drive is shared, both households will want the same information before the day is booked.

Frequently asked questions
No, provided the sealer suits the gradient. Tradies use penetrating sealers or add a non-slip grit to film-forming ones on slopes. Say the gradient worries you and the quote will name the finish.
It slows it a great deal. The clean removes the growth, the biocide kills the spores and the sealer denies them a foothold. Overhanging branches that keep the drive wet can still be pruned within council limits.
Yes, and doing both halves together usually makes sense. Both owners need to agree on the product and the day, since neither car can use it while the sealer cures.
The tradie places bunds or sausages across the kerb line, directs water onto lawn or garden, and vacuums or sweeps up what is left. Stormwater drains here lead to the beach or Pittwater, so nothing but rain should enter them.
