How Often Should You Pressure Wash Your Driveway or Paving? Experts Explain
For most homes, an annual clean is ideal. But "most homes" hides a lot. How often your paving really needs pressure washing comes down to three things: climate, traffic and the type of paving.
1. Climate and shade
Moisture drives moss and algae. Gauteng's summer rains, and any paving that stays damp in the shade of trees, walls or buildings, grow organic matter much faster. In humid or heavily shaded spots, cleaning every six months keeps moss and algae under control.
In the dry winter months the problem changes: red Highveld dust works into the paving and dulls it.
2. How much use it gets
A driveway with three cars in and out every day, plus visitors, delivery vans and the odd oil leak, will need more attention than a quiet garden path. Busy residential driveways and complex entrances often benefit from a clean every six to nine months.
3. Paving type
- Concrete pavers are durable but porous, and they absorb oil and dirt.
- Clay brick is softer, so it needs gentler cleaning, but it often looks dramatically better afterwards.
- Natural stone and slate need careful, low-pressure cleaning and benefit from sealing.
Quick guide
| Property | Suggested frequency |
|---|---|
| Typical home, sunny driveway | Once a year |
| Shady, damp or tree-covered paving | Every 6 months |
| Busy complex driveways and entrances | Every 6–9 months |
| Commercial and retail properties | Quarterly |
| Before selling or a big event | A few weeks before |
The key principle
Watch your surfaces. If you see green or black patches, weeds in the joints, slippery spots or fresh oil stains, clean before the contaminants cause permanent staining or surface damage. Regular cleans are quicker, cheaper and kinder to your paving than one big rescue job.
