THE ESTIMATING ANSWER
For one existing counter opening, start with a defined scope and measurement basis. Measure the cutout, bowl depth, cabinet clearance and waste alignment before selecting the product. Separate sink, basket waste and fitting labour; identify whether tap reuse is confirmed. Price the listed tasks separately and state the condition that would require a revision: A cutout that does not fit or damaged counter edge changes the base scope.
This guide uses a fictional project in Winnipeg, Manitoba: One existing counter opening. 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
Replace one sink at an existing countertop opening with a selected compatible sink, new waste connection parts and final seal. Retain the existing tap where suitable. Measure the cutout, bowl depth, cabinet clearance and waste alignment before selecting the product. 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: Measure the cutout, bowl depth, cabinet clearance and waste alignment before selecting the product.
2. Build a product and labour schedule
Separate sink, basket waste and fitting labour; identify whether tap reuse is confirmed. This example has 7 distinct lines, including measure and countertop protection, old sink removal, sink product allowance. Use actual supplier prices and labour inputs for a customer job; the displayed amounts are fictional document inputs.
Selections to confirm: Separate sink, basket waste and fitting labour; identify whether tap reuse is confirmed.
3. Sequence the work and handoffs
Confirm the countertop material and shutoff access before the old sink is lifted. 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 the countertop material and shutoff access before the old sink is lifted.
4. Set a change boundary
A cutout that does not fit or damaged counter edge changes the base scope. The example excludes countertop replacement, new tap purchase or concealed cabinet repair. Record the discovery, agree the revised work and update the estimate before adding it to the job.
If the job changes: A cutout that does not fit or damaged counter edge changes the base scope.
Review the Canadian job address
Verify the existing water, waste and fixture connections on site. Confirm who handles any required trade work, approvals and inspections for this address; this fictional document does not decide them.
Count the actual units, site visits and selected products separately. A count in this example is a document input, not a substitute for inspecting the real property. 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 sink removal: 1 each × C$175.00 = C$175.00.
- Sink product allowance: 1 each × C$620.00 = C$620.00.
Adding all 7 rounded line amounts gives C$1,750.00. 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 |
|---|---|---|---|
| Measure and countertop protection | 1 job | C$130.00 | C$130.00 |
| Old sink removal | 1 each | C$175.00 | C$175.00 |
| Sink product allowance | 1 each | C$620.00 | C$620.00 |
| Waste and connector allowance | 1 set | C$155.00 | C$155.00 |
| Sink fitting and seal | 1 each | C$350.00 | C$350.00 |
| Drain reconnection and test | 1 job | C$210.00 | C$210.00 |
| Disposal and clean-up | 1 job | C$110.00 | C$110.00 |
| Illustrative subtotal | C$1,750.00 | ||
Scope and pricing boundaries
Replace one sink at an existing countertop opening with a selected compatible sink, new waste connection parts and final seal. Retain the existing tap where suitable.
Outside this example: No countertop replacement, new tap purchase or concealed cabinet repair.
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
- Measure the cutout, bowl depth, cabinet clearance and waste alignment before selecting the product.
- Separate sink, basket waste and fitting labour; identify whether tap reuse is confirmed.
- Confirm the countertop material and shutoff access before the old sink is lifted.
- A cutout that does not fit or damaged counter edge changes the base scope.
Check the business, client, property, dates, line extensions and notes. The kitchen sink replacement 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.
