How Much Does It Cost To Build A Composite Decking?

Today, composite decking has become the go-to-material for many homeowners for building a deck. This specific type of material resembles wood, but it is extremely durable and hardly needs maintenance. If you think that composite is right for your new deck, then you should look into certain factors that affect its cost.  

Deck Material & Size

The deck material and the size of your deck play the largest role in determining the cost of your composite decking. With average prices range from $100 – $350 per square metre, you can estimate what such a range computes to.


Another factor that affects the price of your decking is the labour. While experienced D-I-Yers can install decks on their own, contacting a licensed decking professional would be a great idea. While it can raise your total investment, you can enjoy a perfectly-finished product.

Material Type:

Polyethylene-based, Polypropylene-based and Polyvinyl Chloride (PVC)-based decking are the three main types of composite decking materials, but many homeowners prefer using PVC-based composite decking for a number of reasons. However, this particular type of material costs you 20% more than other two types of materials.

Solid Or Hollow Or Scalloped:

If you are looking for a light-weight yet strong decking board, you can go with hollow planks. On the other hand, if you want something heavier and durable, solid composite deck boards can be a good option. In addition to these two types of decking boards, you have budget-friendly scalloped deck boards. These planks have scalloped bottom, making them lighter and cheaper.

Additional Materials:

Apart from the actual cost of decking, the additional materials or add-ons you require can get expensive. When it comes to accessories, the options are limitless. Depending on your design, you can choose between post caps or a gate kit. Trim, end caps and handrails are other accessories that can raise the overall cost of your decking project.


While composite decks are made from plastic and wood, the manufacturers use a variety of techniques to make them look more realistic. The planks with finer details as the real timber will come with higher price tags. On the other hand, the decking planks with a little grains and common colour shade will be considerably cheaper.
