Before we dive into the installation process, let’s take a closer look at Timbertech decking and its benefits. Timbertech composite decking is made of a blend of recycled plastic and wood fibers, providing a sustainable alternative to traditional wood decking. It is resistant to moisture, rot, and mold, making it an ideal choice for outdoor spaces. Additionally, Timbertech decking comes in a variety of colors and textures, allowing you to customize your deck according to your preferences.

Proper installation is essential to ensure the longevity and safety of your Timbertech deck. A poorly installed deck can result in structural damage, tripping hazards, and other safety concerns. Therefore, it is crucial to follow the manufacturer’s guidelines and local building codes when installing Timbertech decking.

Pre-Installation Preparation

Before you begin the installation process, there are a few essential steps you need to take to prepare for the project.

Gather Necessary Tools and Materials

To install Timbertech decking, you will need the following tools and materials:

  • Measuring tape
  • Chalk line
  • Circular saw
  • Drill
  • Hammer
  • Level
  • Safety glasses
  • Work gloves

In addition to these tools, you will also need Timbertech decking, fasteners, and substructure components such as joists, beams, and posts. Make sure to purchase the correct amount of materials based on the size and design of your deck.

Check Local Building Codes and Regulations

Before you start the project, it is crucial to check your local building codes and regulations regarding deck installation. Some areas have specific requirements regarding the height, size, and placement of decks, as well as the use of certain materials and construction methods. Failure to comply with these regulations can result in fines or legal issues.

Determine the Layout and Design

Before you start building, determine the layout and design of your deck. Consider factors such as the size, shape, and orientation of your outdoor space, as well as your lifestyle and preferences. You can use online design tools or consult with a professional to help you create a plan that meets your needs and budget.

Framing and Substructure

The framing and substructure of your deck are the support system that holds up the decking boards. Here’s how to install the framing and substructure for your Timbertech deck:

Install the Ledger Board

The ledger board is the first component you need to install. It is a horizontal board that attaches to your house and supports the deck’s weight. To install the ledger board, follow these steps:

  1. Mark the height and position of the ledger board on the house using a chalk line.
  2. Drill pilot holes into the house’s framing studs.
  3. Attach the ledger board to the house using lag screws.
  4. Use a level to ensure the ledger board is straight.

Install the Joists and Beams

Once the ledger board is installed, you can start building the substructure. The joists and beams are the main components of the substructure that support the decking boards. To install the joists and beams, follow these steps:

  1. Determine the spacing of the joists and beams based on the size and design of your deck.
  2. Cut the joists and beams to the appropriate length using a circular saw.
  3. Install the beams perpendicular to the ledger board using metal joist hangers.
  4. Install the joists parallel to the beams and attach them to the ledger board and beams using metal joist hangers.
  5. Use a level to ensure the joists and beams are straight.

Add Support Posts

If your deck is high off the ground, you will need to add support posts to the substructure. To add support posts, follow these steps:

  1. Determine the placement of the support posts based on the size and design of your deck.
  2. Dig holes for the support posts using a post hole digger.
  3. Insert the support posts into the holes and use concrete to secure them in place.
  4. Install post anchors on top of the support posts and attach the beams to them using metal brackets.

Installing Timbertech Decking

Now that the substructure is in place, it’s time to install the Timbertech decking. Here’s how to do it:

Choose the Right Fasteners

Timbertech decking can be installed using either hidden fasteners or face screws. Hidden fasteners provide a clean, seamless look, while face screws are visible but more secure. Make sure to choose the right type of fasteners based on your preferences and the design of your deck.

Choose the Right Installation Method

There are two installation methods for Timbertech decking: traditional face screws and the CONCEALoc® hidden fastening system. If you choose to use face screws, make sure to drill pilot holes to prevent the decking boards from splitting. If you choose to use the CONCEALoc® system, make sure to follow the manufacturer’s instructions carefully.

Start Laying the Boards

To start laying the boards, follow these steps:

  1. Place the first board against the house and secure it to the ledger board using fasteners.
  2. Use a chalk line to ensure the first board is straight.
  3. Install the remaining boards, spacing them evenly and using fasteners to secure them to the substructure.
  4. Cut and trim the boards as needed to fit around obstacles and edges.

Make sure to stagger the seams of the decking boards for a more attractive and stable deck.

Finishing Touches

Congratulations! You’re almost done with your Timbertech decking installation. The final step is to add some finishing touches to your deck to enhance its appearance and functionality.

Cut and Trim the Boards

Once you’ve installed all the decking boards, you may need to trim some of them to fit the edges of your deck. Use a circular saw to cut the boards to the desired size, and make sure to sand any rough edges. Additionally, you can use a router to create decorative edges on the boards for a more polished look.

Install Fascia Boards

Fascia boards are typically installed on the perimeter of the deck to cover the ends of the decking boards and provide a finished look. They also help to protect the substructure and prevent moisture from seeping in. Use screws to attach the fascia boards to the rim joists and ensure that they are level and flush with the decking boards.

Add Railing

If your deck is elevated or located in an area with a drop-off, you may need to install a railing for safety purposes. Timbertech offers a variety of railing options, including composite and aluminum railing systems, to complement your deck’s design. Follow the manufacturer’s instructions to install the railing securely and ensure that it meets local building codes.

Maintenance and Care

Now that your Timbertech deck is installed, it’s essential to maintain and care for it properly to prolong its lifespan and keep it looking its best.

Tips for Maintaining a Timbertech Deck

  • Keep the deck free of debris: Sweep or blow off leaves, dirt, and other debris regularly to prevent them from accumulating on the deck’s surface.
  • Move outdoor furniture and potted plants regularly: Leaving heavy objects in one spot for an extended period can cause indentations or discoloration on the deck’s surface.
  • Avoid dragging heavy objects: If you need to move heavy objects across the deck, use a dolly or lift them instead of dragging them.

How to Clean and Protect the Deck

  • Use a mild cleaning solution: Mix warm water and mild detergent in a bucket and use a soft-bristled brush to scrub the deck’s surface gently. Rinse thoroughly with a hose.
  • Avoid harsh chemicals: Do not use bleach, ammonia, or other harsh chemicals to clean the deck, as they can damage the surface and void the warranty.
  • Apply a protective coating: Timbertech recommends applying a protective coating to the deck’s surface every 1-2 years to prevent fading, staining, and water damage.

Regular Inspection and Repairs

Inspect your Timbertech deck regularly to identify any signs of damage, such as warped or loose boards, cracks, or rot. Address any issues promptly to prevent further damage and ensure the safety of your family and guests. Contact Timbertech’s customer service team for guidance on repairs or replacements.
