Blower Door Testing For Penticton Builders
Blower-door airtightness testing for Penticton Part 9 builders: mid-construction diagnostics, final testing, readiness checks, and as-built reporting support.
Airtightness problems are expensive when the final occupancy test is the first time anyone measures the envelope. By then, drywall and finishes can hide the joints, penetrations, top plates, service chases, and membrane transitions that need attention. The safer path is to test while the air barrier is still accessible, then confirm the completed home at final.
Apollo sets up calibrated blower-door equipment, pressurizes or depressurizes the building, finds leakage paths, and works with the builder, site team, or insulator while they seal gaps during the test. Mid-construction testing produces a preliminary air leakage result, practical site feedback, and a real-time view of measured air leakage dropping. Final testing produces the airtightness result needed for the as-built package.
Timing: For Penticton projects, the City describes airtightness testing at mid construction and building completion. Book the mid-construction visit after the primary air barrier is installed and before insulation, vapour barrier, drywall, or board cover key details. Book the final visit when exterior openings, penetrations, and mechanical systems are complete enough for occupancy-stage documentation.
What to send: Send drawings or a share link, permit address, municipality or AHJ, current project stage, target inspection or occupancy date, site contact, and any City card, Step Code form, or AHJ instructions already issued. If you are not sure which visit you need, start with the mid-construction guide or the Penticton Step Code guide.
Use testing while leaks are still reachable.
- Test after the primary air barrier is installed and visible
- Walk likely leakage areas with the builder, site lead, or insulator
- Seal obvious leaks during the test when materials and authority are available
- Document the preliminary result and observations for the project file
- Use the findings to reduce final-test risk before finishes cover the details
Confirm the completed envelope for closeout.
- Schedule once exterior openings and envelope penetrations are complete
- Confirm the building can be set up for a stable airtightness test
- Coordinate with mechanical, ventilation, and as-built reporting timing where needed
- Capture construction changes that affect the final energy file
- Use the final result in the occupancy-stage documentation package
Make the visit productive before Apollo arrives.
- Windows and exterior doors are installed, latched, and reasonably sealed
- Temporary openings, attic hatches, and service penetrations are closed or ready for temporary closure
- Air-sealing materials are on site if active sealing is planned
- Someone familiar with the air barrier strategy is available for the walk-through
- Work that will cut new envelope penetrations is not still pending after the test
Avoid delays that make the result less useful.
- Testing too early, before the shell can hold pressure
- Testing too late, after leakage paths are hidden by insulation or finishes
- Missing site contact, access, power, or permission to operate openings
- Unclear air-barrier location or details that differ from the drawings
- Final test requested before mechanical penetrations or exterior openings are finished
What builders ask before booking.
When should the mid-construction blower-door test happen?
Schedule it when the primary air barrier is built and still visible, before insulation, vapour barrier, drywall, or board cover details that may need correction.
What is different about the final airtightness test?
The final test documents the completed building envelope for the as-built energy file, while the mid-construction test is diagnostic and focused on finding leaks while they are still repairable.
What does Apollo document?
Apollo documents the preliminary or final airtightness result, the testing context, and the builder-facing leakage observations needed to move the file forward.
Is this only for Penticton?
Apollo is based in Penticton and serves builders across the Okanagan-Similkameen, including nearby town and regional district projects.
