This Trex Transcend deck replacement in Seattle, WA, transformed a rotted wood deck into a new 350-square-foot outdoor space. The project included extending the existing layout, working around challenging angles and elevation changes, and modifying the area beneath the deck for storage. Trex Transcend decking, matching composite railing, and skirting completed the multi-level design. A five-person crew finished the project in approximately 1.5 weeks.

Deck Repair Seattle: Why Full Replacement Was Needed
The original wood deck had rotted, so limited deck repair was not sufficient. Deck resurfacing would not have addressed the planned extension or the structural changes involved in creating the new multi-level layout. Its location on a sloped yard also created challenging angles and elevation changes for the new deck construction.
Homeowner Goals and Planning With a Custom Deck Builder
The homeowner wanted to upgrade from wood to Trex Transcend decking and extend the deck. Another goal was to make better use of the area underneath it by modifying that space for storage.
For this Seattle outdoor project, the right design needed to combine a larger usable surface, multiple levels, composite materials, storage below, and a layout suited to the property’s changing elevations.
The Trex Deck Installation
As the deck contractor, our team replaced the rotted deck and extended the layout to create a 350-square-foot composite deck. The new configuration follows the sloped yard’s changing elevation and complex angles. This Seattle deck shows how we design decks around actual site conditions rather than applying a standard rectangular layout.
We installed Trex Transcend railing around the deck and used skirting to finish the lower portion of the project. We also modified the under-deck area for homeowner storage.
Composite Deck Materials Used
| Material | Use |
| Trex Transcend decking | Main deck surface |
| Trex Transcend composite railing | Railing system |
| Skirting | Lower deck finish around the modified storage area |
Composite boards are made from wood-plastic blends and synthetics. Composite decking requires less routine maintenance than real wood, making it a practical material for homeowners seeking long-term performance from an outdoor living space. Most composite decks last 25 to 50 years if installed correctly.
Our Deck Construction Process
The deck construction scope included replacing and extending the rotted deck, installing Trex Transcend decking and railing, adding skirting, and modifying the space below for storage. Five crew members completed the deck installation while working with the yard’s different elevations and angles.
Project Timeline
