A slippery, green slime often coats the north-facing vinyl siding in Bel Air. It feels like a thin layer of soap when touched, which usually indicates organic film rather than just surface dust.
Recent field behavior shows this buildup trapping moisture against the siding.
✅ Texture: Slimy, velvet-like organic growth.
✅ Visual: Dull, dark streaks in shaded areas.
✅ Behavior: Algae holding onto textured vinyl grains.
✅ Symptom: Discoloration that doesn't brush off.
Pressure washing removes this layer without scrubbing. We use specific pressures to ensure the vinyl doesn't warp or crack under the stream.
