Don Valley moss and algae: Homes near the Don Valley ravine develop moss, algae, and lichen on north-facing driveways, walkways, and patios. This isn't just cosmetic — biological growth makes surfaces dangerously slippery. Pressure washing alone removes the visible growth but doesn't kill the root structure. It grows back within months. Effective treatment requires a biological pre-treatment (sodium hypochlorite or oxygen bleach) before pressure washing to kill the organism, then purified rinse to prevent rapid regrowth.
