Assess the Existing Substructure
Before selecting any new deck hardware, a comprehensive inspection of the existing substructure is essential. This includes joists, beams, posts, and ledger boards. Look for signs of rot, insect damage, cracks, or excessive deflection. Even if the visible decking is worn, a compromised substructure can lead to safety issues and premature failure of new decking materials.
Verify the spacing of your existing joists. If your existing joist spacing does not match the requirements of your chosen decking, you may need to add blocking or sister new joists, which will impact your hardware selection and overall project scope. For example, a wider joist spacing might necessitate thicker decking boards or a different fastening approach to prevent sagging.
Check the ledger board connection to the house. Ensure it is securely fastened and flashed properly to prevent moisture intrusion. Any issues here should be addressed before new decking is installed, as this is a primary structural connection.
Evaluate Existing Fastening Systems and Compatibility
Consider the type of fastening system currently in place. Is it face-screwed, or does it use a hidden clip system? If you plan to reuse any existing hardware, ensure its material is compatible with your new decking and any new fasteners. Mixing certain metals, for instance, can lead to galvanic corrosion, weakening connections over time.
If switching from face screws to a hidden clip system, verify that the new decking material is designed to accommodate such clips. Not all decking boards are grooved or profiled for hidden fasteners. Additionally, the specific clip system chosen must match the board profile and thickness. For instance, a clip designed for a thin composite board may not properly secure a thicker hardwood plank.
When planning a renovation, remember that the fastening system is an integral part of the overall deck assembly. Bring your material choice and any drawings to a Lumber Plus branch to ensure the fastening system can be checked as one package. This ensures all components work together effectively.
Material Compatibility for New Decking and Hardware
The choice of new decking material (hardwood, composite, PVC) dictates the type of hardware and accessories required. For example, hardwood decking often benefits from specific stainless steel fasteners to resist corrosion and minimize staining, especially in exterior applications. Composite and PVC boards may require specialized screws that prevent mushrooming or cracking.
Consider the environmental exposure of your deck. For coastal areas or regions with high humidity, corrosion-resistant hardware is a priority. Stainless steel (e.g., 305 or 316 grade) is generally recommended for its durability in challenging environments. Ensure any new structural connectors or fastening solutions are rated for the intended application.
Think about the finish you desire. If you are using a visible face-screw system, consider fasteners with color-matched heads or plugs that blend with the decking material. If a clean, uninterrupted surface is preferred, a hidden fastening system, which utilizes clips and screws that are concealed between boards, may be a better choice. These systems require specific installation tools and components.
Planning for Decking Installation Tools and Accessories
A renovation project may require specific installation and finishing tools tailored to your chosen material system. If you are moving to a hidden fastening system, you might need specialized drivers, spacers, and possibly a fastening tool designed for that particular clip type. For hardwood decking, pre-drilling and countersinking tools are often necessary to prevent splitting and ensure a flush finish.
Consider accessories that enhance the longevity and aesthetics of your renovated deck. This could include fascia support clips for a clean edge finish, integrated lighting options for stairs and railings, or cleaning and protection products for compatible wood products. These items should be planned alongside your primary hardware selection to ensure a cohesive project.
Hypothetical Renovation Example: Replacing Deck Boards on an Existing Frame
A homeowner is renovating a 10-foot by 12-foot deck. The original decking was pressure-treated pine, face-screwed, and is now severely weathered. The homeowner wants to upgrade to 1x6 (actual 0.75-inch by 5.5-inch) tropical hardwood decking and desires a hidden fastening system for a cleaner look.
The homeowner will need to remove all existing decking and fasteners, carefully inspecting the joists for any remaining damage or protruding fasteners.
For the new 1x6 hardwood, a compatible hidden clip system designed for 0.75-inch thick boards and appropriate for tropical hardwoods would be selected. These clips typically require a specific groove along the edge of the decking board; if the chosen hardwood does not come pre-grooved, a router accessory would be needed to create the necessary profile.
The project would require approximately 264 linear feet of 1x6 decking for the 120 square feet of surface (120 sq ft / (5.5 inches / 12 inches/ft) = 261.8 LF, rounded up). Additional hardware would include starter clips for the first board, end clips for the last board, and stainless steel screws for securing the perimeter and fascia boards. This example highlights the need to verify board dimensions, clip compatibility, and total quantities based on joist layout.
Before you order
- Inspect existing substructure (joists, beams, posts, ledger board) for integrity.
- Measure existing joist spacing and compare with new decking requirements.
- Identify current fastening system and assess its compatibility with new materials.
- Determine if new decking material is suitable for hidden clips or if face-screwing is preferred.
- Verify material compatibility between new decking and chosen fasteners (e.g., stainless steel for hardwoods).
- Consider environmental exposure (e.g., coastal) and select corrosion-resistant hardware.
- Plan for necessary installation tools and accessories (e.g., specialized drivers, spacers, routing bits).
- Account for perimeter, stair, and fascia fastening requirements.
- Budget for integrated lighting or maintenance products if desired.
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
Can I use my old deck screws with new composite decking?
It is generally not recommended. Old screws, especially if they are not specifically designed for composite materials, may not provide adequate holding power, could corrode, or might cause 'mushrooming' (raised material around the screw head) in the new decking. New composite decking often requires specialized screws that are color-matched, self-countersinking, and designed to prevent mushrooming. Always refer to the decking manufacturer's recommendations for compatible fasteners.
Do I need to replace my deck joists if they look okay?
While joists may appear fine, a thorough inspection is crucial. Look for soft spots, rot, insect damage, or excessive deflection. Even if visually sound, their structural integrity might be compromised. If joist spacing does not meet the requirements for your new decking, or if there's any doubt about their condition, it's safer to reinforce or replace them. Consulting with a professional or a Lumber Plus expert can help determine their suitability.
What are the benefits of a hidden fastening system for a renovation?
Hidden fastening systems offer a clean, fastener-free deck surface, which enhances aesthetics and can reduce the risk of splinters. They can also improve the longevity of the deck by allowing for better drainage and minimizing moisture traps around screw heads. However, they require specific grooved decking boards and may be more complex to install than traditional face-screwing. The initial cost of materials might also be higher.
