Central Construction Fence & Deck - Seattle's Local Privacy Fence Installation

Seattle's frequent rain and shade create the perfect environment for moss and algae to grow on fence surfaces. If left unchecked, moisture can seep into the wood, causing rot. During new deck construction, we can install proper spacing, use treated or naturally rot-resistant woods, and add drainage gaps that reduce moisture buildup on nearby fences. This helps keep moss from taking hold and extends the life of both your deck and fence.

Yes, fence post erosion and rot are very common in Seattle because of our wet soil and freeze-thaw cycles. Signs include soft or flaking wood near the ground line, leaning posts, or visible moss growing at the base. For deck repair, we can replace rotted posts with pressure-treated lumber or install concrete footings to lift wood away from moist soil. For your fence, we use galvanized post anchors and gravel bases to improve drainage and prevent future erosion.

If more than 30% of your deck boards or support posts show deep rot, structural cracks, or extensive moss damage, replacement is often more cost-effective than repeated repairs. In Seattle, we see many older decks where the original wood wasn't rated for our damp climate. A full deck replacement allows us to start with advanced moisture barriers, composite materials, and proper flashing that resists moss and rot long-term. We can also redesign the layout to improve sunlight exposure and airflow—two natural moss deterrents.
