Deck Estimate

What types of decks are we currently installing?

There are loads of new products coming into the decking market, so we have provided our top three types of decking that we are currently installing below.

HardieDeck™ decking is made from James Hardie’s premium fibre cement. It creates a clean look to connect a stylish interior environment with the outdoors, without risking damage from the elements. Smooth, wide gap-free boards and freedom of colour choice makes this cement decking a stunning outdoor floor.

Timber Hardwood Decking

If you are looking to extend your home with a new deck, or create additional room for living outdoors, we can help. We can design something that will look and function best, in the space that you have to work with. We work with a range of timber and alternative products.


The most popular timber decking choices we typically use are Treated Pine, Spotted Gum, Merbau, Jarrah and Blackbutt.

Millboard Decking

Millboard composite decking is hand-made in the United Kingdom & styled from real oak timbers, creating an incredible realistic look that captures the natural beauty of wood. But unlike traditional timber – which needs regular on-going maintenance like oiling & sanding to try and stave off rotting, mould, stains, warping, cupping, fading, splinters & a host of other undesirable effects – Millboard is totally different!

We can highly recommend Joel and his team at BTM Exteriors. Their workmanship is of an exceptionally high standard, their prices are very competitive, and they are super efficient. They were a pleasure to deal with, full of ideas & suggestions, always honest, and we would without hesitation employ their services again when required. The Hardiedeck they installed looks amazing…it complements our pool beautifully, and brings to life our alfresco area. It’s easy to keep clean, and much easier to maintain than a timber deck. It has without doubt added value to our home. We wish dealing with tradesmen was always this easy!” – Client Testimonial, Aug 2018
