Short answer
A useful deck price covers the whole build, not just the boards. Compare the frame, footings, access, stairs, balustrades, finishes and approval responsibilities before comparing totals. AriJah provides project-specific quotes rather than a universal per-square-metre rate.
Start with the space you actually want to use
Before asking how much a deck costs, describe what it needs to do. A landing for a back door, an outdoor dining area and an elevated entertaining deck are different projects even when their floor areas look similar. Sketch the table, chairs, barbecue and path to the garden. Leave room to walk around furniture rather than measuring an empty rectangle.
For example, a proposed 4 m by 5 m platform has 20 square metres of floor area. That measurement is useful, but it does not describe its height, how you reach it or how it connects to the house. Treat it as the start of a brief, not a way to calculate a finished price from a generic internet rate.
Separate the visible finish from the supporting work
Deck boards are the part you see. Ask the quote to identify the proposed framing, footing work and fixing system as well. An existing frame should not be assumed reusable just because its boards can be removed. Its condition and suitability need assessment before a resurfacing budget becomes a replacement-deck budget.
Ask for materials to be named clearly enough to compare alternatives. A timber or composite label alone leaves plenty undecided: board profile, fastening method, edge finish and the supporting system can all differ. Our timber-versus-composite article covers the material decision; this checklist focuses on making the priced scope clear.
Account for access, demolition and the edges
Send a photo of the route from the street to the proposed deck as well as the deck area itself. Narrow side access, steps and an occupied garden change how materials and waste can move through the property. Point out items you want protected, such as paving, planting or an existing fence.
Stairs, handrails, balustrades, fascia and screening deserve their own discussion. They are easy to miss when a quote conversation centres on floor area. Write down whether removal of the old structure, waste disposal and making good adjoining surfaces are included. Do not assume that a roof, lighting or painting comes with the deck unless it is stated.
Compare three columns, not just three totals
Set up a simple comparison with one column for each contractor. Use the same rows: dimensions, materials, substructure, demolition, access, stairs, edge protection, finishing, approval-related work, exclusions and the total including applicable taxes. Put a question mark beside anything that is not described rather than treating it as included.
Then send each contractor the questions that remain. If one price includes removal and another does not, those totals are not yet comparable. The QBCC homeowner guidance linked below is a useful starting point for finding contractors and comparing quotes. The aim is a clear agreement about the result, not a competition to produce the lowest-looking number.
Improve the brief before cutting the budget
If the first scope is beyond your budget, identify priorities. Would a simpler shape or fewer decorative features still deliver the outdoor space you want? Ask for separately priced options so you can see what changes. Do not treat a necessary structural or safety component as an optional saving.
For a North Brisbane enquiry, send AriJah the suburb, approximate size, photos, access details and whether this is a new deck or a replacement. Include your preferred finish and budget range if you have one. These details help turn an initial conversation into a focused site assessment without pretending a photo alone can settle every construction detail.

Frequently asked questions
Can you give me a price from a photo?
Photos and dimensions help define the job, but site conditions and the supporting structure still need assessment before a reliable final scope and quote.
Is the cheapest deck quote the best value?
Not necessarily. First check that the materials, inclusions and exclusions are comparable. Ask for unclear items to be explained in writing.
Are these example dimensions a project price?
No. The 4 m by 5 m example only explains floor area. It is not an AriJah project specification, cost estimate or offer.
