THE SHORT ANSWER
Estimate an exterior entry door by the measured opening, selected prehung unit, threshold details and surrounding finish. Keep product, fitting and weather closure visible rather than quoting a bare door price.
This guide follows a fictional one prehung entry door in Brandon, Manitoba. The linked exterior entry door replacement PDF example shows the scope and 7 separate costs in Canadian dollars. Treat it as a worked document, then use measurements, supplier quotes and labour inputs from your own project.
1. Identify the replacement assembly
Record opening dimensions, swing, sill and hardware selection. A slab-only job differs from this prehung replacement in both product and labour.
2. Inspect the existing opening
The sample assumes suitable framing and adjacent finishes. Hidden deterioration or enlargement requires a separate inspected scope before proceeding.
3. Detail weather and hardware work
List threshold, weatherstrip and handle fitting responsibilities. Clarify which components come with the selected unit so allowances do not duplicate supplier packages.
4. Define finish and disposal
State whether casing, paint, exterior trim and old-door disposal are included. The touch-up allowance here is limited, not a full wall or siding refinish.
Review the Canadian project address
For the one prehung entry door in Brandon, Manitoba, the example uses the measured trade units shown in its PDF. Residential jobs may mix square feet, linear feet, counts and supplier units; keep each line’s measurement basis visible. Check exposure, access, drainage and any concealed water damage at the property. Confirm the selected product and local approval requirements before setting the final scope. The figures are fictional CAD inputs, not a local price survey.
Describe which products the customer supplies and which the contractor supplies. State how any site condition outside the visible scope will be assessed and priced. Do not copy an allowance from another city or assume a sample’s tax entry establishes the treatment for this client.
Work through the exterior entry door replacement quantities
The matching PDF lets the client check each extension of quantity and unit rate. For this example, two useful checks are:
- Existing door and frame removal: 1 each × C$335.00 = C$335.00.
- Prehung entry door allowance: 1 each × C$1,460.00 = C$1,460.00.
Adding all 7 lines gives a C$3,670.00 illustrative subtotal. The PDF records 0% tax and C$3,670.00 as its total, before any markup. These are chosen sample inputs, not prices observed in Brandon, Manitoba. The measurement basis matters as much as the rate: a material purchase allowance may be larger than the installed area, while a fixture count is not interchangeable with hours of labour.
Check the scope before sending
- Measure opening, swing and threshold.
- Confirm selected unit and hardware.
- Inspect framing and adjacent finishes.
- Define trim and disposal limits.
Outside the illustrated scope: No opening enlargement, structural repair, siding replacement, full repainting or specialty security system integration.
Check the business and client names, property location, dates, quantities, unit rates and notes. Confirm tax, markup and any required approvals for the actual job. If selections or site conditions are unresolved, label the line as an allowance and explain how it will be updated.
Common questions
Is an exterior door the same scope as an interior door?
No. Threshold and weather closure details need explicit consideration along with the selected assembly and opening.
Does the price include painting?
Only where stated. This example has a trim touch-up allowance but no complete door or wall repaint.
