Composite decking designed and installed for Mandurah homes. WA Maintenance builds practical outdoor living spaces using low-maintenance composite decking selected to suit your property, lifestyle and the coastal conditions found throughout Mandurah and the Peel Region.
Composite decking for outdoor living in Mandurah
A well-planned deck can turn an unused outdoor area into a comfortable space for entertaining, relaxing and moving between the home and garden. Composite decking provides the appearance of timber without the same regular sanding, oiling and staining routine required by many natural timber products.
WA Maintenance considers the complete structure, not just the visible boards. Ground conditions, access, drainage, ventilation, deck height, subframe design and connections to the home all influence how the finished deck performs. As a qualified carpenter, Martin brings practical building knowledge and careful attention to each residential project.
Benefits of composite decking
- Lower routine maintenance: composite boards generally do not require regular oiling or staining.
- Consistent appearance: choose from a range of colours, profiles and wood-look finishes.
- Outdoor durability: quality products are designed to handle sun, rain and regular use.
- No timber splinters: a useful consideration for family entertaining areas.
- Versatile design: suitable for ground-level decks, alfresco extensions, poolside areas and garden platforms, subject to the site and product specifications.
Choosing the right composite decking
Composite boards vary in composition, surface texture, profile, warranty conditions, fixing systems and price. Colour is important, but it should not be the only consideration. Darker boards can become warmer in direct sunlight, while the surrounding architecture and amount of shade will affect how a colour looks throughout the day.
We can discuss board orientation, edge details, transitions, ventilation and the relationship between the deck and existing doors, paving or landscaping. Product selection is confirmed for the individual project so the materials and installation method work together.
Composite decking or timber decking?
Composite decking suits homeowners who want a timber-style appearance with less ongoing maintenance. Natural timber offers its own character and can be sanded and refinished over time, but usually needs more frequent care. The best choice depends on the appearance you prefer, exposure to weather, maintenance expectations and budget.
Our main Decking Mandurah page covers our broader decking service. During the quotation, we can discuss whether composite or timber is the more practical fit for your home.

- Design and material selection: the layout, boards, subframe and finishing details are confirmed for the scope.

- Completion: the deck is checked, the work area is cleaned and maintenance guidance is provided.
Composite decks for different spaces
Alfresco and entertaining areas
Composite decking can create a comfortable connection between indoor and outdoor living areas. Board direction, finished height and transitions deserve careful planning so the deck feels integrated with the home.
Poolside decking
Pool surrounds require particular attention to drainage, ventilation, fixing requirements and the chosen product’s suitability for wet areas. Slip characteristics and surface temperature should also be considered when selecting boards.
Garden decks and platforms
A small garden deck can provide a level seating area or make better use of a sloping or awkward part of the property. Access beneath the deck and future landscaping requirements are considered during planning.
Built for Mandurah’s coastal environment
Mandurah properties can experience strong sunlight, wind, salt exposure and seasonal moisture. Product selection, appropriate fixings, board spacing and ventilation all matter. We install composite decking in accordance with the requirements of the chosen system and the conditions of the site.

Frequently asked questions
How much does composite decking cost in Mandurah?
The price depends on the deck size, height, access, ground conditions, subframe requirements, board selection, stairs, edges and other finishing details. A site-specific quote provides a much more accurate figure than a generic square-metre rate.
Does composite decking get hot?
All decking can warm up in direct sunlight. Colour, board composition, exposure and shade affect surface temperature. Lighter colours and thoughtful placement may help, but product-specific information should be considered before selection.
Does composite decking require maintenance?
Composite boards generally require less maintenance than timber, but they still need routine cleaning and care. Following the manufacturer’s instructions helps protect the appearance of the deck.
Can composite decking replace an old timber deck?
Sometimes, but the existing structure must be assessed first. Reusing a subframe is only appropriate when its condition, spacing, levels and construction are suitable for the selected composite system.
