Building a deck in Lincoln County is not the same as building one in the Willamette Valley. The Oregon Coast puts more stress on outdoor structures than almost anywhere else in the Pacific Northwest. Salt-laden air corrodes standard fasteners within a few years. Over 60 inches of rain per year saturates wood framing and accelerates rot. Sustained winter winds of 40 to 60 mph put lateral loads on railings and overhead structures that inland decks never face.
Every material choice we make accounts for these conditions. We use stainless steel or triple-coated structural screws rated for coastal exposure. Ledger board connections get self-adhering flashing tape and proper spacing to prevent moisture trapping against the house sheathing. Joist tape goes on every horizontal framing member to stop water from pooling on the top edge of joists, which is the number-one cause of premature deck framing failure on the coast.
Fiberon composite decking is engineered for exactly this environment. The boards have a protective PermaTech cap layer that resists moisture absorption, UV fading, and mold growth. Unlike natural wood, composite will not cup, split, or check after repeated wet-dry cycles. The color holds for the life of the product without sanding or restaining. For homeowners who want a deck that looks the same in year ten as it did the day it was built, composite is the clear choice for coastal Oregon.
We also design for drainage and airflow. Proper joist spacing, adequate ground clearance, and strategic placement of ventilation gaps beneath the deck surface keep air moving and moisture from accumulating. In areas prone to standing water, we install under-deck drainage systems that channel runoff away from the foundation and protect the space below the deck for storage or additional usable area.
