How To Build Floating Deck: Step By Step Guide

There is nothing quite like floating decks for turning your yard into a true oasis. These raised platforms, also known as floating decks, are built above the ground and create an attractive space for having fun outside, spending some quiet time alone, or enjoying the beauty of nature around you. Unlike typical floating decks that are attached to a house, they “float” free-standing. Floating decks can be relatively easy to build with the right approach.

Why Choose a Floating Deck

Floating decks are a great option with several benefits. One of the main advantages is their versatility – since they are not attached to any structure, they can be placed almost anywhere even on uneven or sloping terrains; this makes them particularly suitable for sites with poor drainage as there will be no need for extensive excavation works and concrete footings. Moreover, these types of decks offer chic contemporary lines that will refresh any outside space.

Planning Your Deck Vision

Before swinging a hammer, carefully evaluate your yard to pinpoint the ideal deck spot. Envision how you’ll primarily use the space – entertaining, peaceful lounging, outdoor dining? This will help determine the appropriate size and shape. Consider any potential obstructions like trees or landscape features. A relatively level area with adequate drainage is ideal.

Minding Your Permitting P’s & Q’s

Depending on your local municipality’s rules and codes, you may need to obtain a permit before construction can commence. Do your homework by checking with the appropriate authorities to understand any requirements or restrictions specific to deck projects where you live. Avoiding this step can result in Code violations and fines.

Choosing Built-to-Last Materials

The materials you select will significantly impact your deck’s final look, longevity, and maintenance needs. For framing, pressure-treated lumber is a classic, affordable option. When it comes to decking boards, wood-alternative composite products offer impressive durability and little maintenance. You’ll also need cement blocks or paving stones for the foundation, along with typical tools like saws, drills, levels, and more.

Establishing a Solid Foundation

To begin with, carefully map out your desired deck’s dimensions and mark the full footprint area. Furthermore, use a level to identify any significant high/low spots that may need minor grading or ground leveling. Moreover, laying down a weed barrier fabric helps prevent vegetation growth under the deck over time.

Placing the Foundation Blocks

Within the footprint area, position cement blocks or paving stones every 3-4 feet in a grid pattern. Additionally, take the time to level each block using a spirit level, shimming with gravel underneath as needed to achieve an even, stable surface across the grid.

Tying It All Together

With the blocks evenly positioned, install pressure-treated wood planks cut to span tightly between each block. Secure these planks to the blocks using either exterior-grade screws or construction adhesive to create a cohesive, level foundation framing.

Framing the Deck Platform

Laying the Support Structure

It’s now time to build out the deck’s support platform. Firstly, start by running pressure-treated lumber beams perpendicular across the foundation framing at 16-24″ intervals, depending on decking product span ratings. Additionally, level and secure beams using exterior screws/adhesive.

Assembling the Joists

Next, install joists perpendicular across the support beams at 16″ intervals to provide a sturdy surface for decking boards. Moreover, use joist hangers and exterior structural screws to attach each joist, ensuring the entire structure remains level and properly spaced throughout.

Framing the Outer Edges

To create a clean, finished edge around the perimeter, install a double-rim joist. Furthermore, these should be attached to the ends of each joist using joist hangers, providing a solid nailing surface for decking boards and any railing system.

Installing the Decking Surface

Before installing deck boards, make any necessary cuts to perimeter boards for proper fit. It’s also wise to perform a dry layout of all boards to check spacing, stagger pattern, and expansion gaps (particularly crucial for wood-alternative composite boards).

Securing the Deck Boards

Begin securing deck boards at the outer edge, working inward row-by-row. Follow the manufacturer’s guidelines for any required expansion spacing between boards and secure each plank to the joists using exterior-grade decking screws driven at an angled surface.

Putting on the Finishing Touches

With decking surfaces installed, add any desired decorative touches like fascia trim around the perimeter or contrasting inlay patterns with framed borders. This is also the stage to install railing systems if wanted for safety and aesthetics. As a final step, apply any recommended stains, sealants, or preservatives based on your decking material.

Caring for Your New Deck

Keeping it Looking Its Best

To maintain your deck’s gorgeous appearance, schedule regular cleaning into your outdoor maintenance routine. Use a dry brush, broom, or leaf blower to remove dirt, leaves, or debris that may accumulate. Every few months, give deck surfaces a more thorough scrub using a solution of mild detergent and water. Avoid using harsh chemical cleaners or high-pressure washers that can potentially damage the deck.

Conduct Annual Inspections

On an annual basis, perform a thorough inspection of every deck component – from surface boards down to the foundation footings. Check for any loose screws/fasteners, cracked or rotting boards, damage to framing, or stability issues with the foundation blocks/paving stones. Catching small problems early allows for quick fixes before more extensive repairs are required.
