Most homeowners in Eurobodalla leave their driveway until it's visibly black with grime. By that point, you're not just dealing with surface dirt — you've got embedded algae, oil stains, and mould that's worked its way into the concrete. A regular cleaning schedule is far easier and cheaper than waiting for a full restoration job.
Here's the honest answer to how often you should be cleaning your driveway, based on surface type and your local conditions.
The Short Answer
For most homes in Eurobodalla: once every 12–18 months is the sweet spot. Coastal properties near salt air, homes under trees, or heavily used driveways may need it every 6–12 months.
It Depends on Your Surface
| Surface Type | Recommended Frequency | Why |
|---|---|---|
| Concrete | Every 12–18 months | Porous — absorbs oil and algae quickly |
| Exposed Aggregate | Every 12 months | Rough texture traps dirt and organic growth |
| Pavers | Every 12–18 months | Joints collect weeds and moss |
| Asphalt | Every 2 years | Less porous, but needs sealing after clean |
| Stamped Concrete | Every 12 months | Grout lines hold grime, needs gentle pressure |
Signs It's Time for a Clean Right Now
- Dark staining or black patches (algae or mould)
- Green tinge — especially in shaded areas (lichen growth)
- Slippery surface when wet — this is a safety issue
- Oil stains from vehicles
- Visible weed growth between pavers or cracks
- The driveway looks noticeably darker than when it was new
What Happens If You Leave It Too Long?
Algae and lichen aren't just cosmetic problems. They secrete acids that slowly break down concrete and tile surfaces. On pavers, organic growth in the joints accelerates cracking. On exposed aggregate, embedded grime is significantly harder to remove — and sometimes requires chemical treatments that cost more.
From a safety standpoint, algae-covered driveways become dangerously slippery when wet. This is especially relevant in coastal areas like Eurobodalla where humidity is high year-round.
Does Sealing After Cleaning Help?
Yes — significantly. Sealing concrete or pavers after a professional clean creates a barrier that makes future cleaning easier and pushes your next required clean out by 6–12 months. It also protects against oil penetration and UV fading. We can advise on sealing as part of our service.
DIY vs Professional Pressure Washing
Hiring a pressure washer and doing it yourself is possible, but there are a few risks:
- Too much pressure — hire equipment is often over-powered and can etch concrete or damage pavers permanently
- Wrong technique — uneven passes leave visible stripe marks
- No pre-treatment — skipping a degreaser or algaecide means the stains come back faster
- Safety — high-pressure water can cause serious injuries
A professional clean with the right equipment and pre-treatment products delivers better results that last longer — which ultimately costs less over time.
