THE ESTIMATING ANSWER
For one straight flight and landing, start with a defined scope and measurement basis. Count individual treads and risers, record widths and measure the landing separately; roll layout affects purchasing. Separate carpet roll allowance, underlay and stair fitting labour. Price the listed tasks separately and state the condition that would require a revision: Curved steps or unsound stair edges change the fitting pattern and preparation.
This guide follows one straight flight and landing in Perth, Western Australia. The matching itemised estimate and PDF show how the job brief becomes measured quantities and separate AUD amounts. The responsible role in this scenario is flooring contractor. Check the actual site, selected products, supplier figures and labour plan before issuing a client quote.
Cost to re-carpet stairs: count the flight and specify the finish
To estimate the cost to re-carpet stairs, prepare a stair schedule rather than using the room's floor area. Count treads and risers, measure widths and record landings, turns and any open sides. Identify whether the carpet covers the entire stair or forms a runner. These choices affect the purchasing layout and the amount of edge finishing included.
Separate old covering removal, carpet and pad allowances, fitting labour and landing work. Ask the supplier or installer to confirm the purchasing quantity from the chosen carpet width and pattern before ordering. A nominal number of steps cannot establish material quantity without dimensions. Keep any stair repairs or replacement of individual treads outside ordinary carpet fitting until their condition is assessed.
For a comparable quote, write down the agreed appearance at the edges, how the landing joins the adjoining floor and whether furniture or stored items must be moved. Explain who supplies decorative accessories when applicable. Stairs with damaged components or an uncertain specification need a separate assessment; increasing a carpet allowance cannot resolve the underlying scope or safety question.
A separate worked planning example
Independent illustrative arithmetic: a hypothetical flight of 12 steps at A$25.00 per step produces A$300.00 of fitting labour. An invented A$180.00 carpet allowance and A$60.00 removal line bring this limited scope to A$540.00. These hypothetical inputs are not market rates and do not replace the amounts in the linked PDF.
Cost and scope questions
Can I estimate stair carpet by the number of steps?
Use the step count for a clearly defined labour line, but measure tread, riser, width and landing details to establish the selected carpet purchase quantity.
Does a re-carpet quote include stair repairs?
That requires an explicit repair scope after assessment. Carpet fitting should not imply that damaged treads or structural stair problems are corrected.
1. Define the measured job
Fit selected carpet to one straight stair flight and landing, including underlay, gripper and finishing at two thresholds. Count individual treads and risers, record widths and measure the landing separately; roll layout affects purchasing. Record the measurements and existing condition in the estimate before turning quantities into line items. The scope should make clear why this is a separate project from a broader renovation or maintenance quote.
Measure for this job: Count individual treads and risers, record widths and measure the landing separately; roll layout affects purchasing. Put that measured basis beside the relevant PDF lines so area, fitted length and product purchase quantities stay distinct.
2. Build a product and labour schedule
Separate carpet roll allowance, underlay and stair fitting labour. This example has 7 distinct lines, including stair template and protection, old stair covering removal, carpet allowance. Use actual supplier prices and labour inputs for a customer job; the displayed amounts are fictional document inputs.
Choose before pricing: Separate carpet roll allowance, underlay and stair fitting labour. The fixture separates stair template and protection, old stair covering removal and carpet allowance rather than hiding all work in one figure.
3. Sequence the work and handoffs
Confirm old covering removal and safe use of the stairs during work. Show which task depends on access, a selected product or another trade. If that dependency is still open, label the price preliminary and identify the information needed before a firm quote.
Plan the handoffs: Confirm old covering removal and safe use of the stairs during work. Note which stage needs access, a selected product or another trade before the next stage can be priced confidently.
4. Set a change boundary
Curved steps or unsound stair edges change the fitting pattern and preparation. The example excludes stair structural repair, handrail work or adjacent room carpet. Record the discovery, agree the revised work and update the estimate before adding it to the job.
Change trigger: Curved steps or unsound stair edges change the fitting pattern and preparation. Record the revised task and quantity before it changes the amount your client sees.

The carpet allowance line uses 14.4 m². Keep the site measurement and supplier's selling unit together; a material purchase allowance can differ from installed coverage. The amounts are fictional AUD inputs, not current prices for Perth, Western Australia or another location.
Worked project calculation
The paired PDF has 7 cost lines. For example, Old stair covering removal is 13 step × A$22.86 = A$297.18; Carpet allowance is 14.4 m² × A$68.35 = A$984.24. Each amount comes from the stated quantity and unit rate, so you can trace the arithmetic back to the job scope.
| Work item | Quantity | Unit rate | Amount |
|---|---|---|---|
| Stair template and protection | 1 job | A$184.15 | A$184.15 |
| Old stair covering removal | 13 step | A$22.86 | A$297.18 |
| Carpet allowance | 14.4 m² | A$68.35 | A$984.24 |
| Underlay and gripper allowance | 1 job | A$292.10 | A$292.10 |
| Stair carpet fitting | 13 step | A$73.66 | A$957.58 |
| Landing fitting | 4.46 m² | A$82.00 | A$365.72 |
| Thresholds and cleanup | 1 job | A$196.85 | A$196.85 |
| Illustrative total | A$3,277.82 | ||
Adding every exact-cent line gives A$3,277.82. The PDF uses a 0% tax input only to make its fictional arithmetic visible. Confirm the GST treatment that applies to the actual job and set your own markup before sharing a client quote. A fictional rate is a document input, not a market quote or a recommended selling price.
Scope and pricing boundaries
Fit selected carpet to one straight stair flight and landing, including underlay, gripper and finishing at two thresholds.
Outside this example: No stair structural repair, handrail work or adjacent room carpet.
Separate product allowances, supply, installation, disposal and any specialist work where the actual project needs them. If access or a hidden condition changes, document the affected scope and agree a revised price instead of silently extending the base amount.
Before you send the estimate
- Count individual treads and risers, record widths and measure the landing separately; roll layout affects purchasing.
- Separate carpet roll allowance, underlay and stair fitting labour.
- Confirm old covering removal and safe use of the stairs during work.
- Curved steps or unsound stair edges change the fitting pattern and preparation.
Check business and client details, address, dates, scope, units, line amounts and PDF notes. The stair carpet installation PDF example shows how this fictional project is presented. Its short PDF note is not a substitute for the detailed exclusions above.
