EXAMPLE AT A GLANCE
This fictional St. John’s, Newfoundland and Labrador attic air sealing example has 6 itemized costs and a C$2,488.00 total before tax or markup. The PDF, quantities, unit rates and scope assumptions match the table below.
Use this completed attic air sealing document to see how a specific job becomes a client-facing estimate. The project, business, customer and amounts are fictional. For the defined penetrations in one attic in St. John’s, Newfoundland and Labrador, 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. Record the existing air, moisture and ventilation conditions before selecting materials. Requirements and suitable assemblies depend on the building and location, so confirm them for the actual project. The figures are fictional CAD inputs, not a local price survey.
Project scope: Defined penetrations in one attic
Seal 18 accessible small attic penetrations and 120 linear feet of agreed top-plate joints after a site review. Include temporary insulation movement, approved sealant material allowance, application labour, documentation and cleanup. No new insulation or concealed opening repair.

Measure this work on the actual property before using any quantity. The illustration separates supplied products or materials from installation where the selection could change. A client should be able to compare each line with the agreed work, the selected products and the limits recorded in the notes.
The 6 itemized costs in Canadian dollars
Every row below is taken from the corresponding app-exported PDF fixture. Multiply the quantity by the unit rate to check the amount. These rates were chosen for this fictional example; they are not advertised prices or current averages for St. John’s, Newfoundland and Labrador.
| Work item | Quantity | Unit rate | Amount |
|---|---|---|---|
| Attic review and work marking | 1 job | C$235.00 | C$235.00 |
| Temporary insulation movement | 1 job | C$230.00 | C$230.00 |
| Small penetration sealing | 18 each | C$48.00 | C$864.00 |
| Top-plate joint sealing | 120 linear ft. | C$5.70 | C$684.00 |
| Sealant and backing allowance | 1 job | C$305.00 | C$305.00 |
| Documentation and cleanup | 1 job | C$170.00 | C$170.00 |
| Subtotal / example total | C$2,488.00 | ||
Two calculation checks:
- Small penetration sealing: 18 each × C$48.00 = C$864.00.
- Top-plate joint sealing: 120 linear ft. × C$5.70 = C$684.00.
The PDF shows a 0% tax entry, so the illustrated tax is C$0.00 and the total remains C$2,488.00. This only describes the example. Confirm the applicable tax treatment and any markup for the real job before issuing your estimate.
Assumptions that change the price
Count the penetrations and measure the specific joints planned for treatment. A vague attic-wide line makes it difficult to verify what the crew will actually seal.
Existing insulation may need careful movement and replacement around work locations. The example allows that effort without assuming wholesale insulation removal.
Match sealant and backing to the actual assembly and applicable requirements. The fictional material allowance must be replaced with a job-specific product list.
Outside this example: No blower-door testing, new insulation, concealed cavity repair, ventilation change or hazardous-material handling.
Record the existing air, moisture and ventilation conditions before selecting materials. Requirements and suitable assemblies depend on the building and location, so confirm them for the actual project. An allowance is a stated placeholder, not a promise to cover all work discovered later. If a selected product, quantity or hidden condition changes, update the affected line and explain the revision before proceeding.

Use the structure for a real job
- Replace St. John’s, Newfoundland and Labrador and the example scope with the actual site and customer details.
- Measure the work and confirm the product schedule with the client.
- Replace every fictional CAD rate with your own labour, supplier and subcontractor inputs.
- Check exclusions, approvals, tax, markup and the document’s validity period for the real project.
- Preview the final PDF and recheck the total before sharing.
- Map and count accessible openings.
- Measure joint lengths.
- Review material and assembly requirements.
- Separate testing and insulation.
Common questions
Can attic air sealing be priced by floor area?
Area gives context, but identified openings, joint lengths and access define this example scope.
Is insulation part of air sealing?
Only if separately listed. This sample moves existing material temporarily but does not add new insulation.
