Georgia's humidity and heavy rainfall create perfect conditions for green algae, black mildew and organic staining to spread across fence surfaces throughout the year. If your fence has turned green, grey or spotty, or feels slimy to the touch in damp weather, it is time to schedule professional Fence Washing. Wood fences are particularly vulnerable because moisture trapped in the grain promotes mold growth and accelerates rot, while vinyl fences stain easily and lose their bright appearance without regular cleaning. Southern Elite Exteriors recommends annual or biannual Fence Washing to maintain both the appearance and structural integrity of your fence.
