The short answer
How often your drive needs it
How often should a driveway be power washed?
Once a year or every two years for most Limerick drives. Shaded, north-facing or tree-covered paving greens up faster and may need it every year, because Shannon Airport gets rain on 223 days a year.
| Your drive | How often | Why |
|---|---|---|
| Open, sunny block paving | Every 1–2 years | Dries quickly; weeds in the joints are the main problem |
| Shaded, north-facing or under trees | Every year | Stays damp, so algae and moss grow faster |
| Light concrete or sandstone | Every year | Shows green and black spots sooner |
| Cars parked daily | Every 1–2 years | Oil and tyre marks build up |
| Sealed drive | Less often | Sealer slows staining and regrowth |
Signs it's time
When a drive needs a clean
- A green film that's slippery when wet.
- Weeds or moss in the joints or along the edges.
- Black spots on sandstone or concrete that don't brush off: usually lichen.
- Blocks rocking or sinking, a sign the joint sand has gone.
- Oil or rust marks spreading.

Questions
Questions we get asked
How often should a driveway be power washed?
Once a year or every two years for most Limerick drives. Shaded, north-facing or tree-covered paving greens up faster and may need it every year, because Shannon Airport gets rain on 223 days a year.
Can you power wash a drive too often?
Yes. Every wash takes some joint sand out of block paving and wears soft stone and tarmac a little. Most drives don't need it more than once a year.
How do I keep a drive clean between washes?
Brush it regularly, clear leaves before they rot on it, pull weeds from the joints early and wipe oil spills while they're fresh.
How often should a house be soft washed?
Less often than a drive. A soft wash kills the algae and lichen rather than just stripping them, so it lasts longer.
Is a yearly clean cheaper than leaving it?
Not always, but a very green or stained drive takes longer and may need stain treatment, €20–€50 extra.
