What Our Clients Say

How Is A Blower Door Test Conducted?

For blower door test in Cape May city, NJ, all outside doors and windows are closed properly, and inside doors are kept open to balance air pressure throughout the space. One chosen exterior door is equipped with an adjustable aluminum frame and fabric panel for test installation. A calibrated fan is then attached to the frame and used to depressurize the home to 50 Pascals, which is about the same as a steady 20 mph wind pushing against the structure.

As the fan removes air from inside, exterior air flows in through leaks and gaps in the building envelope. A sensitive nanometer is used to monitor and compare the pressure difference between the blower fan and the home’s interior air. These results are transformed into air changes per hour (ACH), an indicator of the home’s airtightness and its efficiency in NJ conditions.

Preparing for a Blower Door Test in Cape May city, NJ

Before conducting blower door test in Cape May city, NJ, we make sure all heating, cooling, and ventilation fans are switched off. We then perform a brief inspection throughout the home to make sure all exterior doors and windows are tightly shut — even those opening to garages, basements, or spaces outside the thermal envelope. Once the home is prepared, we mount the blower door fan and frame in a central exterior doorway and depressurize the building to 50 Pascals to measure air leakage precisely. When the home reaches negative pressure, outside air infiltrates through openings, making leaks visible. With the help of a thermal imager, we can uncover leaks and weak spots by spotting temperature differences across walls, ceilings, and surfaces near unconditioned spaces. Our team brings chalk, spray foam, and weatherstripping supplies to every job, enabling us to collaborate with homeowners or contractors to seal visible air leakage areas immediately. Once sealing is finished, we conduct an instant retest to ensure the desired blower door score is reached, confirming compliance with Cape May city, NJ building codes.
