Driveway sealing in Killara
Driveways on Killara's big blocks often run thirty or forty metres from the street to a garage behind the house, with a turning circle or a second branch to a side gate. Clay and concrete pavers, exposed aggregate and coloured concrete are all common, and some have sandstone edging or a paved apron at the gate. Shade from gums and oaks keeps the surface damp, so moss and algae spread, and leaf tannin and acorns leave brown blotches. Roots heave pavers and crack slabs. White efflorescence appears on pavers and coloured concrete after wet weeks. Sunny sections of coloured concrete fade while the shaded sections hold their tone, so the colour reads as patchy.
A vetted tradie cleans first with a surface cleaner, a biocide for moss and the right treatment for efflorescence, then lets the surface dry out fully, which under heavy shade may take more than a day. Pavers and sandstone get a breathable penetrating sealer; exposed aggregate suits a low-build product; coloured concrete can be restored with a colour-enhancing acrylic in two coats. On a sloping drive, a non-slip additive is sensible. Cleaning run-off and sealer wash-up cannot go to stormwater, so it is diverted onto lawn or captured. Lifted pavers are relaid first, and any root cutting near a protected tree is checked with Ku-ring-gai Council. In a conservation area, resealing needs no consent.
Photograph the full run of the driveway and close-ups of stains, lifted pavers and efflorescence, and tell us the surface type if you know it. Vetted, independent tradies who seal driveways in Killara and across Ku-ring-gai take the job and quote directly after inspecting. Expect the quote to list the cleaning steps, the sealer and coats, drying and curing times, slip rating on slopes and how run-off is managed. Cars stay off until cured, which on a long drive may mean a day or two of kerbside parking; most Killara streets allow it, though some are narrow. The matching service is free for homeowners.

Frequently asked questions
Usually. After a thorough clean, a colour-enhancing sealer deepens the remaining pigment and evens out sunny and shaded sections. It will not recreate colour that has worn away, so ask for a test patch first.
A sealed surface stops tannin soaking in, so the marks rinse off rather than set. Existing stains are treated during the clean. Regular sweeping still helps under oaks and gums.
Yes. Relaying the heaved section first gives a flat, safe surface and avoids sealing a tripping hazard. If roots from a protected tree are involved, the tradie checks with council before cutting any.
Typically a day to clean and dry and another to seal, longer in winter or after rain. You can walk on it after a few hours and drive on it after a day or two, product permitting.
