How Often Should You Pressure Wash Your Driveway?

Once a year is the right interval for most driveways in Newcastle. That said, three things shorten the gap.

1. Overhanging trees

Eucalyptus and melaleuca drop sap, bark, and tannin-stained water year-round. If you have one over your driveway, you will notice black streaking within six months of a clean. Clean every six months, or live with it.

2. Oil leaks

Motor oil does not come off with a garden hose. Fresh oil can be lifted with a commercial degreaser applied before the pressure wash. Oil that has been baking in the Newcastle sun for twelve months is much harder — multiple treatments and mechanical agitation may be needed. If a car leaks regularly, clean as soon as the leak is fixed. Waiting makes the job harder and the stain permanent.

3. Commercial driveways and car parks

Higher foot and vehicle traffic means faster soil build-up. Most commercial sites benefit from quarterly cleaning. This also matters for OH&S — a greasy car park is a liability.

When pressure washing is the wrong call

Pressure washing is not appropriate for driveways with:

• Cracked or spalling concrete where water will get under the slab
• Freshly poured concrete under 28 days old
• Pavers with failing sand joints — the water will wash the sand out entirely

If your driveway fits any of these, speak to a concreter before booking a clean. We will tell you the same thing.

What a professional clean actually does

A standard driveway pressure wash removes surface soil, algae, moss, and light staining. We pre-treat with a biodegradable degreaser for oil, then pressure wash at the right PSI for the surface type. Concrete and exposed aggregate handle higher pressure than terracotta or sandstone pavers.

The result is not just cosmetic. Algae and moss hold moisture against the surface and accelerate surface cracking over time. A clean driveway lasts longer.

How much does a driveway pressure wash cost in Newcastle

A standard driveway pressure wash costs $299–$599. Size is the biggest factor — a single-car driveway sits at the lower end, a double or extended driveway toward the top. Heavy oil staining adds time and cost regardless of size, as the concrete needs degreaser pre-treatment and additional passes.
