Materials and Tools Needed

First off, let's talk about the materials and tools you'll need. The choice of materials was crucial for longevity and compliance with my "no cut, no dig" rule.

Pressure-treated lumber: Essential for outdoor projects as it withstands the elements. I opted for this for all my deck pieces.
Deck blocks: A game-changer for avoiding digging. They provide a stable base without needing to disturb the soil.
Screws specifically for pressure-treated wood: To ensure the decking boards remain secure over time.
Weed barrier fabric: To prevent weed growth under the deck.
Tools: A drill (or two to speed up the process), a tape measure, a simple saw (only if minor adjustments are needed), and a level.

Why These Materials?

Pressure-treated lumber is resistant to rot, making it ideal for outdoor use.
Deck blocks remove the need for concrete and digging, streamlining the process.
Weed barrier fabric is a must to keep the area under the deck low maintenance.

Step by Step Instructions

Learn how to build a DIY floating deck with our step-by-step instructions. From planning to laying deck boards, build your perfect outdoor space.

Step 1: Planning and Preparation

I evaluated my backyard and decided on a 14-foot by 8-foot deck. Drawing a plan helped me visualize the project and calculate the materials. Remember to account for the space between decking boards for water drainage and expansion.

Step 2: Laying the Foundation

Placing the deck blocks: I spaced the blocks according to my plan, ensuring they were level. This step is crucial for the stability of the deck.
Adjusting blocks: It's likely you'll need to reposition them slightly to ensure everything is perfectly aligned.

Step 3: Assembling the Frame

Building a rectangle with your outer boards: This forms the perimeter of your deck.
Marking joist placement: Every 16 inches, to ensure even support across the deck.
Assembling off-ground: To make sure the frame was square, I assembled it adjacent to its final position.

Step 4: Positioning the Frame

Once the frame was complete, I moved it onto the deck blocks. This required some muscle but ensured that the frame was elevated from the ground.

Step 5: Laying the Deck Boards

Placement: Starting from one edge, I laid the decking boards across the joists, leaving a small gap between each for drainage.
Securing: Each board was secured with screws into the joists. An important tip is to have the 'frowny' side of the boards facing down to prevent water collection.

Mistakes to Avoid

Not planning for the weed barrier first: I had to partially disassemble the frame to place my weed barrier. Do this before laying down your deck blocks.
Forgetting internal support: Initially, I neglected to place a few deck blocks for additional support in the center. This was a misstep, easily corrected but best avoided.

Customization Ideas for Your Floating Deck

Building a floating deck is not just about functionality; it's also an opportunity to add a personal touch and enhance the aesthetics of your outdoor space. Here are some customization ideas that can make your deck unique and inviting:

Planters and Greenery:

Built-in Planters: Consider incorporating built-in planters into the deck design. They can be filled with flowers, herbs, or small shrubs, adding life and color to your deck.
Vertical Gardens: If space is limited, vertical gardens are a great way to include greenery. They can also act as a natural privacy screen.

Seating Options:

Bench Seating: Adding bench seating around the perimeter of your deck not only provides ample seating but also maximizes space.
Swing Seats: For a playful touch, install a swing seat or hammock. It's perfect for relaxing and enjoying the outdoors.

Lighting:

Solar Lights: Solar-powered lights are eco-friendly and can be used to illuminate the deck at night without increasing your electricity bill.
String Lights: Hang string lights above your deck to build a cozy and warm atmosphere, ideal for evening gatherings.

Decking Patterns and Colors:

Herringbone Pattern: Lay the decking boards in a herringbone pattern for a visually striking effect.
Staining: Choose a stain color that complements your home's exterior and the natural surroundings.

Privacy Features:

Privacy Screens: Install lattice or horizontal slats as a privacy screen to build a more secluded area.
Outdoor Curtains: Hang outdoor curtains that can be drawn for privacy or opened to enjoy the view.

Entertainment Features:

Outdoor Kitchen/Bar: If you love entertaining, consider adding an outdoor kitchen or bar area to your deck.
Fire Pit: A fire pit can be a focal point and a source of warmth on cooler evenings.

Integration with Landscaping:

Stepping Stones: Build a path of stepping stones leading to your deck, blending it seamlessly with the garden.
Water Features: Incorporate a small fountain or pond near the deck for a tranquil ambiance.

Safety and Accessibility:

Handrails: If your deck is raised, ensure you have sturdy handrails for safety.
Ramps: Include a ramp for easy access, making your deck more inclusive for everyone.

Plan well, use quality materials, and mind details. These ideas are practical and let you showcase your style, making your deck a beloved part of your home.

Troubleshooting Common Issues

When building a floating deck, you might encounter a few hiccups along the way. Here's a guide to help you troubleshoot some of the most common issues:

Uneven Decking Boards:

Cause: This often happens due to an uneven foundation or warping of the wood.
Solution: Check the foundation for levelness and make adjustments. If the wood is warped, replace the affected boards.

Loose Railings or Posts:

Cause: Railings or posts can become loose over time due to weather conditions or the natural settling of the deck.
Solution: Tighten any loose bolts and screws. If necessary, add additional support or replace parts that are beyond repair.

Squeaky Boards:

Cause: Squeaks are usually caused by boards rubbing against each other or the joists.
Solution: Insert shims or use deck screws to secure the boards firmly to the joists.

Rotting Wood:

Cause: Wood rot is a result of moisture damage, often due to a lack of proper sealing or drainage.
Solution: Replace the rotted wood immediately to prevent further damage. Ensure that your deck has adequate drainage, and apply a water-resistant sealant.

Popped Nails:

Cause: Nails may pop up from the deck's surface, usually because of temperature changes causing the wood to expand and contract.
Solution: Remove the popped nails and replace them with deck screws, which are less likely to come loose.

Staining and Discoloration:

Cause: Stains can occur from leaves, dirt, or water, while discoloration may be due to sun exposure.
Solution: Clean the deck regularly and apply a stain or sealant that offers UV protection.

Cracks in the Deck:

Cause: Cracks can develop over time due to weathering or stress on the boards.
Solution: Fill small cracks with wood filler. For larger cracks, it's best to replace the entire board.

Mold and Mildew:

Cause: These grow in damp, shaded areas, especially if the deck is not cleaned regularly.
Solution: Use a mold and mildew cleaner designed for decks. Improve airflow and sunlight exposure to the affected areas.

Address issues quickly to keep your floating deck safe and beautiful. Regular maintenance prevents problems.
