Diagnostics

Airtightness Testing

Blower door testing to quantify leakage and support airtightness decisions across Alberta.

Fit and next step

Measure air leakage and decide whether to investigate further.

The quote request can start with the service selected. Files are still optional at intake.

When this is useful

  • You need a blower-door result or a baseline for improvement.
  • Drafts, cold rooms, or a missed airtightness target need evidence.
  • Corrections can still be made before finishes close access.

What you receive

  • A test result summary for the agreed building boundary.
  • Notes on test conditions, building stage, and assumptions.
  • Diagnostic observations and findings when leakage-location work is part of the agreed scope.

A blower door test gives you a measured leakage result under controlled pressure conditions. The number creates a baseline; the surrounding context makes it useful. Building type, project stage, attached geometry, and the reason for testing all affect how the result should be read.

The scope can stay simple when only a documented result is needed, or add diagnostic work when the decision depends on where air is moving.

Useful for

  • establishing an airtightness baseline
  • investigating drafts or uneven comfort
  • checking envelope corrections
  • planning a target before finishes close access
  • supporting an agreed documentation package

What the scope can include

  • test setup and a result summary
  • notes on the building boundary, conditions, and assumptions
  • diagnostic observations when leakage-location work is included
  • a short list of findings tied to the decision at hand

Good timing

  • before finishes close access points
  • when drafts or comfort complaints need evidence
  • when attached-building context affects interpretation

What to prepare

Share the building type, current project stage, reason for testing, and any target or documentation requirement already known. Note attached units, access limits, active construction, or previous test results. Drawings and earlier reports are helpful when available, but intake can begin without them.

Boundaries

One result does not locate every leak or explain every comfort problem. Distribution, ventilation, weather, access, and construction conditions may also matter. Any program, permit, or label decision stays with the responsible authority; this scope provides measurement and supporting context.

Next step

Request a quote with the building type, location, stage, and the decision the result needs to support. We can then confirm whether a result-only test or a diagnostic scope is the leaner fit.

FAQ

Frequently asked questions

Can airtightness be improved after finishes?
Often yes, but it is usually easier before the work is buried.
Do attached buildings test the same as detached homes?
No. Geometry and adjacency change how the result should be read.
