Driveway sealing in Darling Point
Driveways in Darling Point are either shared or steep, and sometimes both. Towers and walk-ups have entry driveways and basement ramps in concrete, marked by oil, tyre scuffs and moss where the ramp sits in permanent shade. Houses below Darling Point Road, Lindsay Avenue and Carthona Avenue have long private driveways falling toward the harbour, in exposed aggregate, coloured concrete, pavers or, on older estates, sandstone flagging. Mature trees drop leaves and sap that stain the surface, and the wet shade breeds algae that turns a slope dangerous. Salt air dulls coloured finishes near the water. Sealing restores colour and resists stains, but on these grades slip resistance comes first.
A vetted tradie pressure cleans the surface, captures the slurry so none runs down to the harbour, which NSW pollution law requires, and lets it dry fully before sealing. On a steep driveway the sealer must include a slip-resistant additive or be a penetrating type that leaves no film; ask which product is proposed. Acrylic or polyurethane systems suit exposed aggregate and coloured concrete; sandstone and pavers need a breathable penetrating sealer that does not trap moisture or change the colour, and on a heritage-listed property any visible change in finish is checked with Woollahra Council first. Strata ramps are sealed in stages so residents keep access while each section cures.
Post the job with photos that show the grade and the surface, say whether it is private or shared, and vetted driveway tradies who work on the point will contact you. Ramps and shared driveways sit on common property, so the quote is addressed to the strata manager. Written quotes set out cleaning method, sealer, slip performance, coats, curing time, access arrangements and run-off handling. Tradies in the network have been checked for identity, ABN, insurance and past work, and homeowners give feedback after each job. There is no charge for the matching and no obligation to hire.

Frequently asked questions
Cleaning off the algae helps immediately. Sealing helps only if the product is chosen for grip: a penetrating sealer or one with a slip-resistant aggregate added. A glossy film sealer on a Darling Point grade would be a mistake. Ask for a trial patch on the steepest part first.
Sometimes, using a breathable penetrating product that leaves the stone's colour alone and lets moisture out; film-forming sealers damage old sandstone. If the property is a heritage item or inside one of the point's conservation areas, check with Woollahra Council before anything that changes the appearance of the stone. Gentle cleaning alone is often the better choice.
By bunding the bottom of the driveway, vacuuming up the wash water and disposing of it properly, or diverting it onto lawn where it can soak in. On the point everything downhill is water, so this is a central part of the job and should be described in the quote.
Usually overnight at least, and longer in cool or humid weather; the product sheet sets the time. The tradie works in sections or over a weekend so the car park stays usable, and the building manager gives residents the exact times when each section is closed.
