Driveway sealing in Gordon

Gordon's older houses often keep two-strip concrete driveways with a grass or gravel centre, laid when cars were narrower, running beside the house to a garage at the rear. Renovated homes have coloured or exposed aggregate concrete and clay or concrete pavers; townhouse rows have shared paver drives; and the apartment buildings have concrete ramps and basement aprons that are common property. Shade from mature gardens breeds moss and algae, leaf tannin leaves brown marks, and roots crack slabs along the strips. Near Stony Creek, flying-fox droppings stain pale concrete. Pavers and coloured concrete show white efflorescence in wet months, and sunny sections fade while shaded ones stay dark.

A vetted tradie cleans first, treating moss with a biocide and efflorescence with the right product, and lets the concrete or pavers dry fully, which can take more than a day under heavy shade. Old plain concrete takes a penetrating sealer that resists stains without a glossy skin; coloured concrete takes a colour-enhancing acrylic; pavers and sandstone take a breathable sealer; and basement ramps need a product with a non-slip finish. Run-off from cleaning and sealer wash-up must not reach the stormwater system; it is directed onto garden beds or collected. The crossing between the kerb and the boundary is council land, so resurfacing it needs Ku-ring-gai Council's agreement, and shared drives need owners corporation approval.

Send photos along the whole driveway and close-ups of the surface, cracks and stains, and tell us whether it is a private drive, a shared townhouse drive or a strata ramp. Vetted, independent tradies who seal driveways in Gordon and across Ku-ring-gai receive the job and quote you directly after seeing it. The quote should cover cleaning steps, repairs to cracks or lifted pavers, the sealer and number of coats, drying and curing times, slip rating and run-off handling. Cars stay off until cured, so plan street parking away from the commuter crush near the station for a day or two. The matching service costs homeowners nothing.
