This project involved a full exterior deck rebuild at a residential property in Washington, DC, using Trex composite decking and matching guardrail systems. The goal was a durable, low-maintenance deck that improves safety, longevity, and overall exterior appearance.
The existing structure was removed and replaced with a newly framed deck, upgraded stairs, and modern guardrails designed to meet current building code requirements.
Project Overview

Trex materials were selected for their durability, resistance to moisture, and long-term performance in DC’s climate.
Why Trex Deck Boards Were Used
Trex composite decking is commonly used in Washington, DC because it performs well in changing weather conditions. Unlike traditional wood, Trex boards do not rot, warp, or splinter and require minimal upkeep.
Key benefits include:
-
No staining or sealing required
-
Resistant to moisture, insects, and UV damage
-
Consistent appearance over time
-
Long manufacturer warranties
Guardrails and Safety Upgrades
The deck guardrails were installed using a Trex railing system with vertical black balusters. This setup improves safety while maintaining a clean, modern look that complements brick exterior homes common in DC.
Guardrails were built to meet local code height and spacing requirements for elevated decks and stairways.
Built for Washington, DC Conditions
Decks in Washington, DC are exposed to humidity, rain, heat, and seasonal temperature changes. Composite decking and PVC-based railing systems are ideal for these conditions because they resist expansion, moisture absorption, and surface deterioration.
This build prioritizes:
