Building Pressure and Blower Door Testing

We provide building pressure and blower door testing services to quantify air leakage, verify air barrier continuity, and confirm that pressurization strategies perform as intended. Testing is performed using calibrated blower door equipment to measure whole building and zone level air leakage under controlled pressure differentials. This data provides a clear, defensible assessment of envelope performance and supports energy efficiency, moisture control, and occupant comfort.

During pressure testing, we use smoke tools and infrared thermal imaging to visually identify leakage paths and thermal defects at walls, roofs, penetrations, fenestration, and transition details. These techniques allow us to pinpoint deficiencies that are not visible during standard inspections and to distinguish between isolated defects and systemic air barrier failures. Testing can be performed during construction to support corrective work or on completed buildings to verify compliance with project requirements and applicable standards.

Results are documented with measured leakage values, annotated imagery, and clear recommendations for corrective action. Our process supports energy code compliance, commissioning and envelope verification, troubleshooting of comfort or pressurization issues, and long term durability planning. This service may be performed independently or integrated into a broader commissioning or energy performance scope, depending on project needs.
