Moss, algae and the green film
Rain, shade and mild temperatures mean green growth shows up on concrete, pavers, decks, north-facing fences and siding around Vancouver. It also makes steps and walkways slippery, which is a bigger problem than how it looks.
Concrete and pavers
These take stronger pressure. On pavers, washing can wash out some of the joint sand, so plan to top it up afterwards.
Decks and fences
Wood needs a lighter touch. High pressure raises the grain and leaves marks. Let the wood dry for a few days before you stain or seal it.
Siding
We use low pressure and rinse downward so water does not get pushed behind the boards.
What we do not wash
Roofs. Pressure strips the granules off shingles and shortens their life. If moss is growing on your roof, a roofer is the right person to call.
