The jobs
Sealing requests come from steep concrete driveways in Mosman, Seaforth, Northbridge and Whale Beach, exposed aggregate around newer homes in Dee Why, Lindfield and Randwick, coloured concrete faded by the northern sun, and sandstone paving and pool surrounds in Vaucluse, Avalon Beach and Hunters Hill. Homeowners post first seals on new concrete, resealing where the old coat has worn thin, stripping of milky or peeling sealer, stain removal and anti-slip treatments for slopes and pool edges. Pre-sale refreshes are common, often alongside a house wash.
Sealing an existing surface is maintenance, not building work, so a contractor licence rarely applies and our checks concentrate on identity and ABN, public liability insurance and photos of local jobs that have held up over time, with references from those clients. On the call we ask about preparation and products: how you clean and strip, how you manage rinse water so none enters stormwater, when you use penetrating sealers rather than film-forming coatings, how you handle efflorescence and curing time on new concrete, and what you do about slip resistance on steep driveways. We also ask how you store and dispose of solvents.
Homeowners expect a quote that spells out preparation, product, coats and the finish they will get, matt or gloss, and a straight answer about how long it should last in their conditions rather than a promise. They expect plants, walls, garage doors and pool water protected from overspray, the driveway usable again when you said it would be and no sealer tracked onto tiles. If a surface is not worth sealing, they expect to be told. Those who get that come back for the reseal and send their neighbours.
What we check for this trade
Frequently asked questions
Not for cleaning and sealing an existing driveway or paving. Laying new concrete, repairing it structurally or paving work valued over 5,000 dollars is building work that requires a Building Commission NSW contractor licence. If you offer both, tell us and we will check the licence.
We do not specify products. We ask that you choose by surface and exposure, follow the manufacturer's data sheet on preparation, coverage and curing, and be able to explain the choice to the homeowner. Penetrating sealers on sandstone, slip additives on steep slopes and proper stripping before recoating are the things we listen for.
Kept out of the stormwater system. Blocking drains, using vacuum recovery or diverting rinse water to lawn and garden are all accepted, as is sewer disposal where arranged. Letting slurry or degreaser run to the street gutter is an offence under NSW environmental law and would end a place in the network.
Yes. Steps, pool surrounds, courtyards and paths come through as often as driveways, sometimes alongside a house wash or deck job. You can set a minimum job size when you apply, and decline anything that does not suit.
