Project scope: One kitchen sink cabinet

Install one selected under-sink drinking-water filter at an accessible existing sink cabinet with compatible supply and a separate dispensing tap if selected.

The fictional project is set in Kingston, Ontario. Cedar & Beam Builders and Jordan Taylor are example names, not a contractor and client case study. The matching guide (https://quicklyestimates.com/en-ca/guides/how-to-estimate-under-sink-water-filter/) explains how measurement, product selection and site conditions affect the estimate.

The 7 CAD cost lines

The table uses the exact items, quantities and unit rates in the app-exported PDF. Multiply each quantity by its rate to check the amount. These chosen figures demonstrate the document; they are not surveyed prices or suggested rates for Kingston, Ontario.

Under-sink water filter installation example · CAD Work item | Quantity | Unit rate | Amount |

Cabinet and supply check | 1 job | C$190.00 | C$190.00 |

Filter kit allowance | 1 each | C$590.00 | C$590.00 |

Tap and connector allowance | 1 set | C$265.00 | C$265.00 |

Mount and pipe filter | 1 each | C$420.00 | C$420.00 |

Counter opening allowance | 1 job | C$205.00 | C$205.00 |

Flush and leak test | 1 job | C$190.00 | C$190.00 |

Cleanup and instructions | 1 job | C$105.00 | C$105.00 |

Illustrative subtotal | C$1,965.00 |

Check the arithmetic

- Filter kit allowance: 1 each × C$590.00 = C$590.00.
- Tap and connector allowance: 1 set × C$265.00 = C$265.00.

The rounded line amounts add to C$1,965.00 . The PDF's tax field is 0%, so its illustrated total stays C$1,965.00 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.

Measurement to verify: Measure cabinet clearances, pipe arrangement, service access and tap-hole plan. Product decision: Separate filter kit, tap and connector allowances; note future cartridge service is outside the quote.

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.

Assumptions and exclusions

Confirm supply isolation and cabinet space before drilling the counter or fitting the unit.

Outside this example: No whole-house treatment, water quality guarantee or countertop replacement.

A countertop that cannot accept the tap needs another product or scope. 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. Confirm a change and update the estimate before adding work that was not in the base scope.
