Spring is the season that everyone is longing to enjoy but that feeling of excitement can easily fade away when you find out the winter season has left its mark on your decking.

Snow damages can result in minor repairs to major renovation work. But whatever repair job you need, you will always end up with one question: ‘how much does decking cost?

If you search how much does decking costs, you may see amounts ranging between $10,000 to $20,000. At first glance at this amount, you probably hesitate to pursue your renovation project because it’s very expensive. There are several factors that influence the decking cost. You just need to know all those factors so you can identify what your decking needs are and what’s not.

What are the factors that influence the decking cost?

Housing Lot Size in Square Metres

The first factor you should consider when deciding to repair or renovate your decking is the housing lot size. There are two reasons why this is important: one, there are some renovation services that require homeowners to seek approval to relevant authorities in their city. And second, the housing lot size is the deck builders’ basis to get an accurate quote for all jobs needed.

These are the following estimated average costs of decking job per square metre:

  • $3,806 to $5,487 for 10 square metre housing lot
  • $3,540 to $5,173 for 20 square metre housing lot
  • $3,672 to $5,292 for 30 square metre housing lot
  • $3,513 to $5,128 for 40 square metre housing lot
  • $3,695 to $5,360 for 50 square metre housing lot

Composite Decking or Timber Decking

Upon knowing the housing lot size, the next factor that you need to consider is choosing what type of decking you want to build. Do you want the conventional timber decking or the modern-age composite decking? Both have the same benefits – can improve your property’s overall value and durability.

You can expect that composite decking may sometimes cost higher than timber decking. But don’t make this a reason to stop you from choosing composite decking because it is a good investment in the long run – environmental-friendly and low maintenance.

Decking Materials

Now that you know what type of decking you want to build, you can now search for the materials for each type of decking and their cost. If you prefer to use timber decking, here are the most popular choices with their pricing range:

  • Jarrah – This material may range from $75 to $450 per square metre.
  • Treated Pine – This material may range from $50 to $200 per square metre.
  • Merbau – This material may range from $60 to $320 per square metre.
  • Blackbutt – This material may range from $88 to $400 per square metre.
  • Silver Top – This material may range from $69 to $70 per square metre.
  • Spotted Gum – This material may range from $70 to $400 per square metre.
  • Ironbark – This material may range from $58 to $450 per square metre.

But if you prefer to use composite decking, its average decking cost per square metre is $4 to $350 per square metre. The cost may still change depending on the brand type and the additional supporting materials it needs.
