Driveway sealing in Clontarf
Most Clontarf driveways are short, steep and shaded, falling from the street to a garage tucked below road level. Exposed aggregate is the common finish because it grips; coloured concrete and sandstone or paver entry courts appear on rebuilt homes. In shade and harbour humidity, moss and black algae establish on the lower run and the edges, and the slope is treacherous when they are wet. Leaf and bark litter from gums and angophoras leaves brown tannin marks. Older film sealers go milky where water sits. A reseal every few years keeps the surface cleanable, slows the moss and stops oil and tannin from soaking in.
The tradie first pressure cleans the drive, kills the moss and algae with a treatment and lifts any oil, then holds off until the slab is dry all the way through. On a shaded Clontarf drive in winter that can take longer than a week of fine weather. For a steep gradient they will usually advise a penetrating sealer that leaves the texture alone, or a film sealer with a non-slip additive; a glossy finish on this slope is dangerous. Wash water and any stripped sealer are held back or sent onto garden beds instead of the drains that flow to the bay, as NSW law requires. Fibro sheeting on a nearby garage or fence is not pressure washed.
Send photos taken from the street and from the garage, plus one close enough to show the surface texture, and say how steep it is. Vetted tradies who seal driveways around Clontarf and the Manly area receive the job and quote you themselves, either from the photos or after measuring. Expect the quote to specify product and finish, coats, preparation steps, how long cars must stay off, and what happens to run-off. Ask what happens if rain arrives mid-job. You choose between the quotes, and nothing is charged to homeowners for the matching.

Frequently asked questions
Yes, but timing matters. The slab must be dry through, so the tradie will look for a run of fine days and may suggest waiting for spring. A moss treatment first is essential on a shaded Clontarf drive.
Not if the right product is chosen. A penetrating sealer keeps the stones' texture, and a film sealer can have grit added. Tell the tradie the gradient and ask for a non-slip finish.
That varies with the sealer and the weather; the tradie will give you a specific window in the quote. On a shaded drive in cool weather it is longer than on a sunny one, so plan parking on the street for that period.
Usually, if they are concrete or the same paving. Sandstone steps need a different product, and anti-slip is even more important on stairs to the water. List every surface in your post so the quote covers them.
