Deck Construction Process: Start to Finish
1. Framing the Deck
We began by constructing the structural framework using pressure-treated lumber. This included installing the ledger board against the house, rim joists, and internal joists to form a solid platform. Joist hangers and structural screws were used for maximum stability and compliance with building codes.
Materials: Pressure-treated 2x10s
Fasteners: Joist hangers, galvanized screws
Spacing: Joists spaced 16” on center for optimal support
2. Sheathing and Waterproofing
Once the frame was in place, we installed the plywood sheathing as the deck substrate. This was followed by a detailed waterproofing process. We used a vinyl deck membrane to create a fully waterproof surface that protects the framing below from moisture and rot.
Sheathing: ¾” exterior-grade plywood
Waterproofing: Vinyl membrane system (heat-welded seams for full protection)
Flashing: Integrated wall and edge flashing to direct water away from the structure
3. Surface Finishing
With the membrane installed, we trimmed the perimeter, sealed all edges, and detailed all corners and transitions. The finish is seamless, slip-resistant, and UV-protected, ideal for year-round exposure.
Benefits: Waterproof, low maintenance, long lifespan
Detailing: Heat-welded seams, vinyl drip edge, and wall upturns
4. Railing Installation
To complete the deck, we installed a glass railing system. The posts are powder-coated aluminum, and the panels are tempered safety glass. The system was surface-mounted directly onto the finished membrane using specialized flashing brackets to maintain waterproof integrity.
Posts: Surface-mounted with base plates and flashing
Glass: Tempered, clear safety panels
Hardware: Stainless steel brackets, corrosion-resistant fasteners
Conclusion
The completed deck is a fully waterproof, low-maintenance outdoor living space built to last. Each phase was executed with careful attention to detail — from the framing to the final railing installation — ensuring long-term performance and safety.
