What Affects Staircase Cost?
- Staircase type: The biggest cost driver is the style of stair being built or upgraded. A handrail or banister only job starts at $2,500 per flight, while straight timber is $9,000, feature timber L or U stairs are $14,000, steel stringer designs are $18,000, and spiral or curved feature stairs reach $28,000 per flight.
- Access and build conditions: Pricing changes depending on whether the work is in an open new build, a replacement in place, or a tight-access occupied home or outdoor area. Open new build or easy access uses the base rate, replacing an existing staircase is charged at 1.2 times the base rate, and tight access or occupied conditions are charged at 1.4 times the base rate.
- Number of flights: This calculator is priced per flight, so total cost increases with each additional flight. A single straight timber flight is $9,000 in an easy-access new build, while two similar flights would double that before any access multiplier is applied.
- Scope of work: Costs are lower when the job is limited to stair railing installation or staircase handrail installation on an existing stair, rather than a full structural stair rebuild. Handrail or banister only work is priced separately from complete staircase installation because it does not include full stair construction.
Staircase Cost - Frequently Asked Questions
For one flight in an open new build or easy-access setting, staircase builders typically charge $9,000 AUD for a straight timber staircase. More complex options increase to $14,000 AUD for a feature timber L or U staircase, $18,000 AUD for a steel stringer or modern design, and $28,000 AUD for a spiral or curved feature staircase. Displayed estimate ranges are generally shown at plus or minus 15% around the midpoint.
Staircase handrail installation is priced at $2,500 AUD per flight in an open new build or easy-access scenario when the job is handrail or banister only. If the handrail is being replaced on an existing staircase, the 1.2 multiplier applies, bringing the midpoint to $3,000 AUD per flight. Tight access, occupied homes, or outdoor conditions use the 1.4 multiplier instead.
For stair railing installation where you are replacing or installing a handrail or banister only, the base price is $2,500 AUD per flight. If it is a replace-in-place job on an existing staircase, that becomes $3,000 AUD per flight using the 1.2 multiplier. In tight-access or occupied conditions, the midpoint increases to $3,500 AUD per flight.
Banister installation is much cheaper than a full stair rebuild because it covers handrail or balustrade work only. The base price is $2,500 AUD per flight, compared with $9,000 AUD for a straight timber staircase, $14,000 AUD for a feature timber L or U design, $18,000 AUD for a steel stringer staircase, and $28,000 AUD for a spiral or curved feature stair.
Yes. Replacing an existing staircase in place uses a 1.2 multiplier on the base rate, so a straight timber staircase increases from $9,000 AUD to $10,800 AUD per flight. The same rule means a steel stringer or modern staircase increases from $18,000 AUD to $21,600 AUD per flight.
Tight access, occupied homes, or outdoor conditions use a 1.4 multiplier, which can noticeably lift the final price. For example, a straight timber staircase rises from $9,000 AUD to $12,600 AUD per flight, while a spiral or curved feature staircase increases from $28,000 AUD to $39,200 AUD per flight. The same multiplier applies to handrail-only jobs, taking them from $2,500 AUD to $3,500 AUD per flight.
