Black pebble-wash is algae, and it is slippery when it rains
Singapore driveways grow a film of algae and moss that a garden hose will not cut. The same film is how an older resident slips on the porch.
| What you see | Likely cause | What to do first / typical cost |
|---|---|---|
| Tyre marks and a green film on pebble-wash | Algae in the aggregate, not mud | Car porch and apron: S$280 to S$520 |
| The boundary wall is black before a repaint | Mould feeding on the old paint | Wall wash and biocide: S$350 to S$680 |
| The condo PES scupper overflows | Silt and algae in the drain | Patio and scupper: S$280 to S$550 |
| The side drain smells and holds water | Silt, and a mosquito site | Full bundle with desilting: S$650 to S$1,450 |
