How to Quote a Staircase Build in Australia
A staircase is a run of joinery that has to carry people and meet the code. Here's how to quote a staircase build so the balustrade, the compliance and the fiddly site work all land in your price.
A staircase is small in footprint and heavy on detail. Treads, risers, stringers, newel posts, a handrail and a compliant balustrade all have to come together to the millimetre — and pass the code. The quotes that lose money treat it like a simple joinery job and forget the balustrade, the waste and the hours. Here's how to quote a staircase build so the number holds.
What a good staircase quote covers
A staircase is more parts than it looks. Before you price it, list every component and every bit of site work:
- Treads and risers — the visible timber, priced per step by species.
- Stringers — the structural sides carrying the load, priced per lineal metre.
- Newel posts, handrail and balustrade — the biggest compliance and cost item, given its own section.
- Demolition — removing an existing stair, where it's a renovation.
- Site prep — scribing to uneven floors and walls, always slower than it looks.
- Finishes and hardware — stain or varnish, brackets and fixings, specified in writing.
- Waste removal — offcuts and demolition spoil, usually a skip or tip runs.
Give the balustrade its own line. It's the part most likely to be underquoted and the part the code cares about most — height, gaps and glass all have rules, and they all cost.
Staircase material costs in 2026
Timber and glass prices move, so quote from current supplier pricing. As a starting point for the main components:
| Component | Typical cost | Notes |
|---|---|---|
| Hardwood treads (spotted gum, merbau) | $30–$80 each | Priced per step |
| Structural timber for stringers | $80–$150/lin m | Carries the load |
| Timber balusters | $10–$50 each | Adds up fast on a full run |
| Glass balustrade panels | $100–$300 each | Must comply with AS 1288 |
All up, a basic straight timber staircase runs around $3,000–$8,000, an L- or U-shaped design $8,000–$15,000, and a custom build in premium hardwood, steel or glass can pass $15,000 — up to $25,000 for architectural work.
Working out labour
Labour is where staircase quotes go wrong, because the fiddly work hides in plain sight. A basic straight timber staircase takes roughly 20–40 hours for a skilled carpenter; complex or custom-fabricated designs can demand 60–100+ hours. Price labour at $70–$120/hour and adjust for anything that isn't square and simple.
- Custom fabrication, curved strings and glass balustrades take far longer per step — don't blend them into a basic rate.
- Renovations mean scribing to out-of-square walls and worn floors; add hours for it.
- Prefabricating off site and having all materials on hand before you start saves real time — factor the efficiency in, not the chaos.
- Allow for set-up, clean-up and travel; they're hours you'll work whether or not you quoted them.
Compliance and Australian Standards
A staircase is a code item, not just joinery. Build the compliance into the design before you price it, because it dictates dimensions and materials.
- The NCC sets tread and riser dimensions and requires a consistent going and rise across the flight.
- Balustrade height and gaps must meet the code — generally 1m minimum above the floor, with restricted openings; loads follow AS 1170.1.
- Glass balustrades must comply with AS 1288; get the grade and thickness right on the quote.
- Where accessibility applies, AS 1428.1 governs — relevant on commercial and some shared-access jobs.
Common mistakes that eat your margin
- Quoting off plans without a site visit. Uneven floors, out-of-square walls and tight access all add hours. Measure on site so the surprises are the customer's, not yours.
- Underquoting the balustrade. It's the slowest, most compliance-heavy part of the stair. Price it as a separate item, never folded into a per-step rate.
- Forgetting waste and transport. Demolition spoil, offcuts and moving prefabricated sections cost money. Leave them out and they come straight off your margin.
- No written sign-off on finishes. Species, stain and hardware are where scope creep lives. Get the choices confirmed in writing before you order.
- Ignoring the code dimensions. Get a going, rise or balustrade gap wrong and it's a rebuild. Design to the NCC first, then price what complies.
Pro tips for a staircase quote that holds
- Always inspect on site before quoting — a staircase is unforgiving of a bad measurement.
- Use a simple 3D drawing or sketch so the customer sees exactly what they're getting.
- Add a 10–15% contingency on renovations, where hidden problems are the norm.
- Specify species, finish and hardware in writing to keep scope creep out.
- Check the NCC and any council requirements for tread, riser and balustrade dimensions before you price.
- Quote the balustrade as its own line so the customer can weigh timber against glass.
ServiceYak keeps your per-step, stringer and balustrade rates in a reusable kit, so you can itemise a staircase quote — treads, strings and a compliant balustrade — and send a clean PDF the same day you measure.
Frequently asked questions
How much does a staircase cost in Australia?
A basic straight timber staircase runs roughly $3,000–$8,000, an L- or U-shaped design $8,000–$15,000, and a custom build in premium hardwood, steel or glass can pass $15,000, reaching around $25,000 for architectural work.
Should I quote a staircase per step or as a lump sum?
Itemise it. Price treads and risers per step, stringers per lineal metre and the balustrade as its own line. An itemised quote is easier to defend and easier to adjust when the customer changes the timber or picks glass.
What standards apply to a residential staircase?
The NCC sets tread and riser dimensions and consistency; balustrade height and gaps must comply, with loads to AS 1170.1; glass balustrades follow AS 1288; and AS 1428.1 applies where accessibility is required. Design to the code before you quote.
