How to Install Garden Decking

Introduction

Installing garden decking can transform your outdoor space into a beautiful and functional area for relaxation and entertainment. Whether you want a simple platform for a garden chair or a full outdoor dining area, decking provides a great solution. This guide will walk you through the process of planning and building your wooden deck, making it a rewarding DIY project.

Required Tools and Materials

Before you start, ensure you have the following tools and materials:

  • Tools:
    • Measuring tape
    • Spirit level
    • Saw (hand saw or power saw)
    • Drill
    • Screwdriver
    • Spanner
    • Post-hole digger
    • Hammer
    • Paintbrush (for wood treatment)
  • Materials:
    • Decking boards
    • Joists
    • Concrete blocks or deck support posts
    • Screws (decking screws)
    • Wood preservative
    • Balustrade materials (if applicable)

Step-by-step Instructions

Step 1: Planning Your Deck

Begin by deciding on the size, shape, and location of your deck. Consider the following:

  • Access to sunlight and shade
  • Proximity to your house
  • Local regulations and planning permissions

Step 2: Preparing the Ground

Clear the area where the deck will be installed. Remove any grass, plants, or debris. Level the ground where necessary to create a stable base.

Step 3: Setting Foundations

You will need a solid foundation for your decking. This can be achieved using either concrete blocks or timber posts. For a solid structure:

  • If using concrete blocks, place them at intervals of no more than 1.2 metres.
  • If using timber posts, dig holes approximately 60 cm deep and set the posts in concrete.

Step 4: Installing Joists

Attach joists to the concrete blocks or posts. Ensure they are level and spaced according to the width of your decking boards (usually around 400-600 mm apart).

Step 5: Laying Decking Boards

Start laying the decking boards perpendicular to the joists. Leave a small gap (around 5 mm) between each board for drainage. Secure each board with screws.

Step 6: Adding Balustrades

If your deck is raised or you want to add a safety feature, install balustrades. Cut the balustrade posts and attach them securely to the corners and along the edges of the deck.

Troubleshooting Section

Here are some common problems you might encounter:

  • Deck boards warp: Ensure wood is treated properly and allow it to acclimatise before installation.
  • Joists squeak: Check that screws are tight and consider adding extra screws if necessary.

When to Call a Professional

While many homeowners can tackle decking projects, there are situations where it’s advisable to seek professional help:

  • If you lack experience in building or construction.
  • If your deck requires complex designs or custom features.
  • If you are unsure about local building codes and regulations.
