How to stop paths and decks getting slippery in winter
Why paths, decks and driveways go slippery in Christchurch winters, and how cleaning and simple changes make them safer.
- Algae and moss on damp, shaded surfaces cause most slips
- Cleaning removes the growth that makes surfaces slick
- More sun and airflow keep them drier for longer
Christchurch winters bring frost, damp and short days. Shaded paths and decks stay wet for long periods, which is exactly what algae and moss need.
Why surfaces get slippery
A thin layer of algae on concrete or timber turns slick as soon as it’s wet. Add frost and leaf litter, and you have a real fall risk, especially for children and older family members.
What helps
- Clean paths, steps and decks before winter to remove algae and moss
- Sweep away leaves regularly so they don’t hold moisture
- Trim plants that shade paths
- Check gutters and downpipes aren’t overflowing onto paths
- Consider anti-slip treatments or strips on steps
Cleaning decks without damage
Timber needs a gentler approach than concrete. A low-pressure wash with a wide fan, working with the grain, cleans without furring the timber. See our pressure washing page for how we handle each surface.
Frequently asked questions
How often should paths be cleaned?
Once a year, ideally in autumn before winter, is enough for most homes. Shaded areas may need it twice.
