Pool / patio enclosures get moldy, and often have a build up of leaves. A simple power washing will bring back the look it once had. Below is a picture of mold on a gutter; every time it rains the gutters drip fungus spores onto the pool deck below. The mold spores that dripped on the pool decks and patios will cause large green and black deposits of Saprophytic Fungus to grow in that area. This fungus arrives and collects on decks and other exterior surfaces (such as pools, patio furniture, etc.) from airborne spores. Once attached to a surface fungus, it begins to feed on the dead organic matter including any organic materials used in the manufacturing process of the item it has attached itself to. In effect, it begins to break down every surface it attaches itself to. Gemini Pressure Washing, in conjunction with chemical cleaning, actually removes and kills, algae, mold, mildew, and fungus that causes this destructive discoloration.
