Signs It Is Time for Fence Washing

Over time, outdoor exposure turns natural wood fences a dull grey and leaves dark streak stains or green algae growth near the soil line. You might notice one side of your fence line looks significantly darker than the other due to shade from trees or neighbouring structures. When timber loses its natural tone or shows spots of dark grime, surface fibers are holding onto moisture, mildew spores, and oxidized wood particles that rain alone will not clear away.

If a weathered or soiled fence goes unwashed, trapped dirt and mildew retain moisture against the pickets and support posts. This constant dampness leads to timber rot, splitting, and loosening around fasteners over time. Applying new stain or sealant directly over unwashed, grey wood locks in organic material and prevents the stain from penetrating deep into the fibers, which causes premature peeling and uneven color patches.

When we arrive at your property, we walk both faces of the fence line to inspect the wood grain, board condition, and soil clearance. We check whether you have natural timber, composite, or vinyl, and identify areas with thick algae or mold buildup. We then use soft-wash methods and dedicated detergents to clean both sides of the fence safely without splintering or marking the wood. For weathered timber, we use a brightening step that resets the wood to its original color, creating a clean, uniform surface for future staining.

Regular washing keeps your fence line clean, delays wood decay, and makes stain application far more durable. Contact us if you would like to discuss your fence washing project.
