The Challenge: A Rotted Wood Deck
The existing wood deck had developed rot and needed replacement. Because this was an elevated deck with stairs, the completed outdoor space also required dependable access and railings suited to its second-story design.
The homeowners chose to replace the deteriorated wood deck with composite decking to reduce ongoing maintenance.
Homeowner Goals for a Low-Maintenance Outdoor Living Space
The main goal was to upgrade from wood to composite decking. The homeowners wanted a new deck that would improve their outdoor living space while reducing the sanding, sealing, and maintenance normally associated with traditional wood.
Their preferred design included:
- A 250-square-foot second-story deck
- Trex Transcend composite decking
- Matching composite railings
- A 12-step staircase
- A clean, practical style for family outdoor living
The Solution: Trex Transcend Composite Decking
Our team completed the deck installation using Trex Transcend decking products for the main deck surface, along with matching composite railings and a staircase connecting the elevated deck to the area below.
This material choice addressed the homeowners’ main goal: replacing the deteriorated wood surface with a lower-maintenance alternative.
