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 uses a fictional project in Winnipeg, Manitoba: One straight flight and landing. Its matching estimate and PDF give each scope decision a visible CAD cost line. Use the document to understand the structure; verify the actual building, product schedule, labour and supplier inputs before preparing a client quote.
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.
Measurement basis: Count individual treads and risers, record widths and measure the landing separately; roll layout affects purchasing.
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.
Selections to confirm: Separate carpet roll allowance, underlay and stair fitting labour.
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.
Work sequence: Confirm old covering removal and safe use of the stairs during work.
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.
If the job changes: Curved steps or unsound stair edges change the fitting pattern and preparation.
Review the Canadian job address
Inspect the existing substrate, access and product selections at the property. Check any local trade or municipal requirements that apply and record unresolved conditions before preparing the final client document.
The carpet allowance line uses 155 sq. ft., approximately 14.4 m². Keep the actual site measurement and the supplier’s selling unit together when you replace this quantity. The example amounts are fictional CAD document inputs, not current rates for Winnipeg, Manitoba or another community. A site visit and current supplier information are needed to replace them.
Work through the itemized calculation
Check each extension of quantity and rate in the paired PDF. Two lines from this project are:
- Old stair covering removal: 13 steps × C$23.00 = C$299.00.
- Carpet allowance: 155 sq. ft. × C$6.25 = C$968.75.
Adding all 7 rounded line amounts gives C$3,241.75. The PDF shows 0% tax and the same total before any markup. The sample shows 0% tax only to make the arithmetic visible. Determine any applicable GST, HST or PST and markup for the actual work before sharing a quote.
| Work item | Quantity | Unit rate | Amount |
|---|---|---|---|
| Stair template and protection | 1 job | C$180.00 | C$180.00 |
| Old stair covering removal | 13 steps | C$23.00 | C$299.00 |
| Carpet allowance | 155 sq. ft. | C$6.25 | C$968.75 |
| Underlay and gripper allowance | 1 job | C$290.00 | C$290.00 |
| Stair carpet fitting | 13 steps | C$73.00 | C$949.00 |
| Landing fitting | 48 sq. ft. | C$7.50 | C$360.00 |
| Thresholds and cleanup | 1 job | C$195.00 | C$195.00 |
| Illustrative subtotal | C$3,241.75 | ||
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.
Keep the product allowance, installation work and any unresolved condition visible as separate decisions. If access or the selected product changes, update the affected quantity or rate and explain the revision before the client relies on the estimate.
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 the business, client, property, dates, line extensions and notes. The stair carpet installation PDF example shows one way to present them. Its short PDF note lists the brief's scope exclusions; the fuller project limits above should guide your own scope.
