Factors that Influence the Cost of Timber Decking Installation Services

Cost of Timber Decking Installation Services

Here’s what to consider when budgeting for timber decking construction.

1. Timber materials

Timbers such as treated pine, Jarrah, Merbau, Blackbutt and Spotted Gum have varied prices and hardness levels. What you choose will largely affect the cost of timber decking. Opt for less expensive softwood such as treated pine to save you money.

In terms of dimensions, the thickness of your timber can have an impact on the cost. It helps to clearly define your requirements to know what type of timber will fit your budget and property needs.

2. Preparation work

Clearing any obstructions such as overgrown bushes, dead leaves and branches will influence the cost of decking.

Ground preparation includes removing the weeds and stabilising the soil. This helps to protect the timber deck from structural problems caused by weeds and pests.

After preparation comes manual digging to install concrete stumps and posts. It is crucial for a deck builder to dig holes in the correct position to ensure that no piping systems will be affected by the construction.

3. Size and location

The length and height of your timber deck can have an implication on how much you will be charged. A professional deck builder will have to initially assess your property and measure the area to provide you with estimates.

Site access is another aspect to check. Where do you plan to build your timber deck? Will it be freestanding or attached to your home? Any structural amendments that need to be done will add to your expenses.

Likewise, building elevated decks is more complex and risky, which may incur larger costs on labour.

4. Extra features

Any job that requires extra labour and materials will attract increased costs. Adding a staircase to a timber deck can make the job longer and more labour-intensive. Balustrading your deck can also impact on your decking cost.

These things should not be overlooked to carefully organise your finances.

How Do You Get Quotes from Timber Decking Builders?

An itemised quotation enables you to compare prices from various timber deck builders. Before hiring a qualified tradie to build and install your new deck, it’s important to:

  • Specify your project requirements to know the scope of work.
  • Check online reviews to see what clients are saying about their service.
  • Ask and verify if they carry updated licences and insurance.
  • Be wary of and clarify upfront charges.
  • Request for a written quotation (i.e. it should provide a breakdown of all items with corresponding costs, schedule, etc).

A clearly defined decking quote from a local deck builder should give you an overview of the price of installation.
