THE ESTIMATING ANSWER
Estimate stair carpet installation by measuring the defined one straight flight and landing, separating product allowances from labour and setting out the work sequence and exclusions. This fictional Birmingham example uses 7 itemised lines totalling £2,066.79; its exact quantities and rates appear in the paired app PDF.
The worked job is one straight flight and landing in Birmingham. The written scope is: Fit selected carpet to one straight stair flight and landing, including underlay, gripper and finishing at two thresholds. Its matching itemised example shows how that description becomes quantities, allowances and a PDF. These figures are fictional inputs for learning the method, so check the real site, specification and supplier or subcontractor costs before quoting.
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. Record the measured basis next to the relevant cost lines, since a room count, fitted length and purchased product quantity may each use a different unit.
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. Keep a named allowance when the selection is open, and replace it once the actual product and delivery terms are known.
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. State which stage needs access or inspection before the next can begin, especially if a concealed condition might stop the 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.
Change trigger: Curved steps or unsound stair edges change the fitting pattern and preparation. If this happens, write down the revised quantity and responsibility before adding an item to the customer estimate.
Worked project calculation
The paired PDF has 7 cost lines. For example, Old stair covering removal is 13 steps × £14.40 = £187.20; Carpet allowance is 14.4 sq m × £43.05 = £619.92. Each amount is the stated quantity multiplied by its unit rate. Recheck whether a line describes installed work, a material purchase allowance or a distinct visit before changing its quantity.
| Work item | Quantity | Unit rate | Amount |
|---|---|---|---|
| Stair template and protection | 1 lump sum | £116.00 | £116.00 |
| Old stair covering removal | 13 steps | £14.40 | £187.20 |
| Carpet allowance | 14.4 sq m | £43.05 | £619.92 |
| Underlay and gripper allowance | 1 lump sum | £184.00 | £184.00 |
| Stair carpet fitting | 13 steps | £46.40 | £603.20 |
| Landing fitting | 4.5 sq m | £51.66 | £232.47 |
| Thresholds and clean-up | 1 lump sum | £124.00 | £124.00 |
| Illustrative total | £2,066.79 | ||
Adding the 7 exact line amounts gives £2,066.79. The PDF uses a 0% tax input and no markup solely to display this arithmetic. Decide the appropriate tax, overhead and profit treatment for an actual job; the fictional rates are not local averages or price recommendations.
Scope and price 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.
The role in this brief is flooring contractor. Confirm who supplies the selected products, makes the site safe, removes waste and signs off the work. Where opening up reveals a different condition, document it and issue a revised scope and price rather than silently extending the base estimate. Also check access, drying or curing time, and the client handoff described in the work sequence.
