Blower Door Test in Waldwick, NJ

Assess your home’s air sealing and energy standards with trusted blower door test in Waldwick, NJ. Our certified specialists support homeowners, builders, and contractors by locating hidden air leaks, improving efficiency, and achieving NJ energy code compliance.

What Is A Blower Door Test?

A blower door test checks the number of air changes per hour in your home, ensuring old air is replaced with new, clean air for a healthier environment. When the air changes too often, energy efficiency drops since the system must continuously reheat or recool the air inside. Too many air changes can create drafts and discomfort due to leaks and may also lead to condensation, moisture buildup, and mold growth indoors. A blower door test in Waldwick, NJ helps spot air leaks before they worsen, improving efficiency, comfort, and long-term structural quality.

What Our Clients Say

How Is A Blower Door Test Conducted?

While performing blower door test in Waldwick, NJ, technicians make sure exterior doors and windows are shut tight and interior doors are open for uniform pressure. A single main exterior door is fitted with an adjustable aluminum frame and attached fabric panel to begin the setup. Once the frame is in place, a calibrated fan is used to bring the home’s pressure down to 50 Pascals — about the same as a 20 mph wind on the structure.

As the fan expels air, the resulting pressure draws outdoor air in through hidden leaks and unsealed joints. Using a highly accurate nanometer, we compare the fan-induced pressure to the natural air pressure inside the home. These results are transformed into air changes per hour (ACH), an indicator of the home’s airtightness and its efficiency in NJ conditions.

What Is A Passing Blower Door Test Score?

Homes throughout Waldwick, NJ are required to satisfy the 2015 International Energy Conservation Code (IECC) or the most current version enforced by local regulators. In most cases, passing the blower door test means reaching 3 air changes per hour or less, proving efficient home sealing. Achieving this goal during your blower door test in Waldwick, NJ promotes energy savings and demonstrates adherence to local building rules.

Why Do I Need A Blower Door Test?

Preparing for a Blower Door Test in Waldwick, NJ

As part of preparing for blower door test in Waldwick, NJ, we power down the HVAC system along with kitchen and bathroom exhaust fans. Next, we carefully walk through the property to make sure all exterior openings — including those to basements, garages, or areas outside the thermal envelope — are closed properly. After sealing everything, we install the blower door frame and fan in a central exterior door and use it to depressurize the home to 50 Pascals for accurate airflow data. When the home reaches negative pressure, outside air infiltrates through openings, making leaks visible. By using a thermal imager, we can spot temperature variations in walls, ceilings, and other surfaces that indicate leaks into unconditioned areas. We’re equipped with chalk, spray foam, and weatherstripping materials, so we can partner with homeowners or contractors to repair visible air leakage problems right on-site. Once sealing is complete, we perform an immediate retest to verify that the desired blower door score is achieved and that your home meets all energy efficiency requirements in Waldwick, NJ.
