Driveway sealing in Dee Why
Strata driveways make up much of the work here: wide concrete runs from the street to carports or a basement ramp, marked with oil drips, tyre scuffs and moss along the shaded edge, with the top coat worn pale by sand. Ramps need grip, so broomed or exposed-aggregate finishes are common and any sealer has to keep that texture. The cottages west of Pittwater Road have single driveways in plain or coloured concrete, faded by sun, and newer houses have pavers or exposed aggregate at the entry. Near the beach, salt crystallising in the surface lifts fine grit from the concrete over time. A clean and seal protects the surface, holds colour and makes oil easier to remove.
A vetted tradie degreases the oil, treats moss, pressure cleans the surface, strips failed old sealer where needed and waits for the concrete to dry completely. On ramps and steep drives the choice is a penetrating product that leaves texture alone, or a film-forming sealer carrying a grit additive; a glossy finish is ruled out. On a strata drive the work is staged so residents keep access to part of the car park. Wash water and degreaser are captured or steered onto garden beds, not down the drains toward the lagoon, as NSW pollution law requires. Fibro garages or fences beside a cottage driveway are not pressure washed. The owners corporation approves any work on a shared drive.
Post a photo from the street, another showing the surface up close and, for a building, the number of spaces and whether the ramp leads to a basement. Vetted sealing tradies who work around Dee Why, Narraweena and Collaroy receive the job and price it for you directly. It should state the sealer and finish, coats, preparation and oil removal, the staging plan for a shared drive, drying time before cars return, and run-off handling; for strata, it should be made out to the owners corporation. You pick from the quotes, and no fee is charged to homeowners or committees for the matching.

Frequently asked questions
Yes, if the tradie stages it in sections and residents move cars as asked. The quote should set out the sequence and how long each section is closed, so the committee can notify owners.
Degreasing lifts most fresh oil; old stains that have soaked in fade but may not disappear. After sealing, fresh drips stay on top and wipe off far more easily.
It needs grip above all. Ask for a penetrating sealer that keeps the broomed texture or a film product with an anti-slip aggregate. A smooth, glossy ramp is a hazard in the wet.
During a dry spell with a mild forecast and light winds, so sand is not blown onto the fresh coat. The tradie will check conditions and may shift the date if an onshore wind or rain is due.
