Driveway sealing in Cremorne
Cremorne has two kinds of driveway. The houses and semis on Cranbrook Avenue, Murdoch Street and Bannerman Street have short, often steep drives in plain or coloured concrete, brick pavers or exposed aggregate, running past sandstone garden walls to a garage beside or under the house. The apartment blocks have shared ramps and forecourts in concrete that take every resident's car twice a day and slope down to basement garages. Both live under figs, jacarandas and street trees that drop tannin, and where shade lingers at the bottom, black algae makes the surface dangerous underfoot in rain. Oil drips, tyre marks and efflorescence on pavers complete the picture a sealer is asked to improve.
First the vetted tradie pressure cleans with a surface cleaner, treating oil and leaf stains first, and since every Cremorne street falls to the harbour, the dirty water is dammed and pumped or directed onto garden or into the sewer instead of the kerb, which is what NSW stormwater law requires. Next comes the product: penetrating sealers that leave the texture and look unchanged, or film-forming sealers that deepen colour and add sheen. On a sloping ramp or drive, a glossy film without an anti-slip additive is a hazard, so the quote should say which it is. Sandstone paths take a breathable penetrating sealer only. The work waits for dry concrete, no dew and a clear forecast.
Upload a photo looking down the drive and one looking up it, say what the surface is, roughly how big, and how shaded. Vetted sealing tradies who cover Cremorne pick the job up and write a quote itemising the clean, stain treatment, product, coats and the keep-off time. Matching is free, and every quote can be turned down. Where the surface is a shared ramp or forecourt, it is common property: the owners corporation gives the approval and the strata manager typically collects quotes against one scope, which we can put to vetted tradies. In the Cremorne and Cremorne Point conservation areas, keep sandstone and old paving looking natural from the street.

Frequently asked questions
Yes, and slip resistance is the main consideration because the ramp is steep and often damp. Ask for a penetrating sealer, or for an anti-slip additive if you want a film-forming finish. The ramp is common property, which means the owners corporation signs off, and the tradie plans the job so residents can still get cars in and out.
Shade and moisture let algae grow on the concrete, and leaves from figs and jacarandas add tannin. A proper clean removes it, and a sealer slows its return by closing the surface. On a permanently shaded section, an occasional wash between seals keeps it safe.
The bloom is efflorescence, salts migrating out of the pavers, and it should be cleaned off with a suitable treatment before sealing, not trapped under a coat. A breathable penetrating sealer is preferred on pavers for that reason. The tradie should mention this in the quote.
Your quote will state it, since product and weather decide it. Walking on it is usually fine well before driving on it, and a shaded Cremorne drive can take longer to cure than the label says. Plan parking on the street for that window.
