Why We Recommend Building a New Deck Over Re-Decking (We do not offer Re-Decking services)
We use premium materials from Armadillo Decking and Dekorators to craft your dream outdoor space. While re-decking can seem like a cost-saving shortcut, it often hides underlying problems like compromised framing or outdated materials. For safety, durability, and long-term value, we choose to exclusively build new decks using premium materials that meet modern codes and standards.

Why We Don’t Offer Re-Decking
Focuses on updating or enhancing current structures.

- ➖ Underlying structure may be compromised
- ➖ Limited layout/design options
- ➖ Doesn’t upgrade to new code standards
💡 Did you know? The structure or framing of your deck only accounts for about 12% of the total cost of a new build. If you’re already investing time and money into replacing the surface boards, why risk leaving an aging or potentially unsafe frame underneath? It’s often smarter, and safer, to start fresh and build it right from the ground up. That’s why we recommend (and only offer) complete new deck builds to ensure structural safety and long-term peace of mind.
Why a New Deck is the Smarter Choice
At STL Design & Build, we only build new decks—no shortcuts, no re-decking, just high-quality, long-lasting structures. While re-decking may seem like a shortcut, it often leaves you with outdated framing that could fail in the near future. When you build new, you gain confidence, customization, and long-term value.
- ✅ Built to Last: Enjoy peace of mind with a brand-new structure that meets modern code and safety standards.
