If your driveway becomes slippery after rain, you’re not alone.
This is a very common issue for homeowners in Exeter, especially due to the damp climate. A slippery driveway isn’t just frustrating — it can also be a real safety hazard.
So why does it happen, and what can you do about it?
1. The Main Cause: Algae and Moss
The most common reason your driveway becomes slippery is the build-up of:
- Algae
- Moss
- Lichen
These thrive in damp, shaded environments — which makes Exeter the perfect place for them to grow.
When wet, these surfaces become extremely slippery.
2. Dirt and Organic Build-Up
Over time, dirt, leaves and debris settle into your driveway surface.
This creates a thin layer that:
- Holds moisture
- Encourages algae growth
- Reduces grip
Even if your driveway looks clean, this layer can still be there.
3. Shaded Areas Make It Worse
If your driveway doesn’t get much sunlight, it’s more likely to stay damp for longer.
This leads to:
- Faster moss growth
- More algae
- Longer drying times
Which all contribute to a slippery surface.
4. Why It’s a Problem
A slippery driveway isn’t just about appearance.
It can:
- Increase the risk of slips and falls
- Be dangerous for children and elderly people
- Create issues when parking or walking on the surface
It’s something that should be dealt with sooner rather than later.
5. How to Fix a Slippery Driveway
The most effective solution is professional pressure washing.
This removes:
- Built-up algae and moss
- Dirt and grime
- Surface contaminants
For block paving, re-sanding may also be needed after cleaning to restore stability.
6. Can You Prevent It?
Yes — regular maintenance helps a lot.
You can:
- Keep the area clear of leaves and debris
- Trim back overhanging plants
- Clean the driveway annually
This helps reduce build-up and keeps your driveway safer.
Final Thoughts
If your driveway feels slippery after rain, it’s usually due to algae and moisture build-up — especially in shaded areas.
The good news is that it can be quickly and effectively resolved with professional cleaning.
