Why Full Deck Replacement Was Needed
In this Sammamish project, the existing structure no longer met performance and longevity expectations. Rather than surface-level repairs, a full rebuild allowed for:
• Proper structural framing
• Improved load support and stability
• Updated stair access and layout
• Long-term resistance to moisture and wear
For projects like this, Deck Construction & Replacement Services is often the most reliable approach when framing and foundational components need to be rebuilt.
Moisture Protection and Structural Integrity
Given the moisture exposure common in Sammamish, additional protection measures were included:
• Proper flashing installed at ledger connection
• Joist tape applied across framing members
• Siding repaired around ledger board as needed
These steps help prevent long-term water intrusion and extend the life of the structure.
Stairs, Access, and Layout Improvements
The project included multiple stair systems to improve usability and flow:
• Two 4-foot-wide side staircases
• One main staircase
• Concrete footings poured at stair bases
All stairs were rebuilt for consistency, safety, and long-term durability.

The finished deck features TimberTech Terrain composite decking, chosen for its durability and low maintenance.
