Assess the Existing Frame's Condition
Before considering any resurfacing, a comprehensive inspection of your existing deck frame is crucial. Look for signs of rot, insect damage, or significant structural weaknesses in joists, beams, posts, and ledger boards. Pay close attention to areas where wood meets the ground or is exposed to consistent moisture.
Check all connections, including fasteners and hangers, for corrosion or loosening. Any compromised components will need to be repaired or replaced. Even if the deck appears sound, an independent inspection by a qualified contractor can uncover hidden issues and ensure the frame is structurally adequate for continued use.
Verify Joist Spacing for Fiberon Decking
Fiberon composite decking, like most composite products, has specific maximum joist spacing requirements to prevent flexing or sagging.
Measure your existing joist spacing accurately. This can add complexity and cost to your project, but it is necessary for the warranty and performance of the decking. (S1)
Consider Material Compatibility and Fastening Systems
Fiberon offers both grooved-edge boards for hidden fasteners and square-edge boards for face fastening. Your choice of fastening system can influence the condition and material requirements of your existing frame.
Hidden fastening systems rely on clips that attach to the joists, requiring a stable and consistent surface. Face fastening involves screwing directly through the board into the joist. Ensure that the existing joists are sound enough to securely hold the chosen fasteners over time. If the joists are pressure-treated lumber, confirm that your chosen fasteners are compatible with treated wood to prevent corrosion.
Evaluate Overall Deck Design and Load Bearing
Beyond joist spacing, consider the overall design and intended use of your renewed deck. Will you be adding heavy features like a hot tub, an outdoor kitchen, or large planters? These additions significantly increase the load on the frame and may require reinforcement, even if the frame appears sound for standard foot traffic. Always consult with a structural engineer or a licensed contractor to confirm the frame's load-bearing capacity for your planned project.
Also, assess drainage and ventilation underneath the deck. Proper airflow is important for the longevity of both the frame and the new composite decking, helping to prevent moisture buildup. Ensure there is adequate space and that existing elements do not impede air circulation.
Worked Example: Joist Spacing Adjustment
The homeowner wants to install Fiberon Concordia decking, which requires 16 inches on center for a straight layout.
This adjustment requires careful measurement, proper attachment of new joists to the ledger and rim joist, and ensuring the new joists are level with the existing ones. This example highlights how frame reuse often involves modifications, not just a simple board replacement.
Always confirm specific joist spacing requirements for the exact Fiberon product line you choose, as these can vary.
Before you order
- Has the existing frame been thoroughly inspected for rot, insect damage, and structural integrity?
- Are all fasteners and connections sound, or do they show signs of corrosion or loosening?
- If joist spacing is too wide, have you planned for adding new joists and confirmed their attachment method?
- Is the frame material compatible with your chosen Fiberon fasteners (e.g., treated wood compatibility)?
- Will the overall deck design, including any new heavy features, exceed the frame's current load-bearing capacity?
- Is there adequate ventilation and drainage beneath the deck to prevent moisture issues?
- Have you consulted with a qualified contractor or structural engineer for a professional assessment?
- Are you prepared for potential frame repairs or modifications before installing new decking?
- Have you confirmed the exact Fiberon product line's specific installation guidelines for joist spacing?
Confirm installation details, approved uses and warranty terms in the current instructions for the exact product and profile. Your installer should verify the substrate, structure and applicable project requirements.
Questions to help you decide
What is the maximum joist spacing for Fiberon decking?
Always consult the specific installation guide for your chosen Fiberon product line to confirm exact requirements. (S1)
Can I install Fiberon decking directly over old wood deck boards?
No, Fiberon composite decking should not be installed directly over existing deck boards. The new decking needs to be installed directly onto a structurally sound frame with proper joist spacing and ventilation. Installing over old boards can trap moisture, lead to improper fastening, and void product warranties.
What if my existing frame is in poor condition?
If your existing deck frame shows significant signs of rot, insect damage, or structural weakness, it is generally not advisable to reuse it. Attempting to install new decking on a compromised frame can lead to safety hazards and premature failure of your new decking. In such cases, a full frame replacement is often the safest and most cost-effective long-term solution.
