What Our Clients Say

How Is A Blower Door Test Conducted?

In blower door test in Lincoln Park, NJ, every exterior door and window is shut, while interior doors stay open to allow uniform airflow inside the building. An adjustable aluminum frame and sturdy fabric panel are installed in one central exterior door to prepare for testing. A calibrated fan is used to depressurize the home through the frame to 50 Pascals, representing the same pressure as a 20 mph wind.

When air is drawn out by the fan, outdoor air seeps in through unsealed joints and hidden cracks. A sensitive device called a nanometer measures how the fan’s pressure relates to the home’s internal air pressure. The pressure data is turned into air changes per hour (ACH), a measure of how efficiently and tightly the home is sealed in NJ.

What Is A Passing Blower Door Test Score?

Properties in Lincoln Park, NJ must meet the efficiency guidelines of the 2015 International Energy Conservation Code (IECC) or the latest version adopted locally. An efficient home in most regions will achieve 3 air changes per hour or less during a blower door test. Reaching this target in your blower door test in Lincoln Park, NJ helps maintain lower energy bills and fulfills local code obligations.

Why Do I Need A Blower Door Test?

Both NJ and local jurisdictions adopt the IECC energy code, making blower door test mandatory for new and renovated residential structures.

How To Pass A Blower Door Test:

Anticipate potential air leaks before testing begins.
Choose Tyvek or Zip Sheathing as your air barrier and check that all seams are securely taped to maintain airtightness.
Install correctly rated insulation with the proper R-value and confirm it’s well positioned in every part of the building envelope.
Seal all penetrations in exterior walls using caulk or spray foam.
Ensure doors and windows are properly installed, caulked, and weather-sealed.
Seal every transition point between conditioned and unconditioned environments, including attics, crawl spaces, and basements.
Many local municipalities issue code compliance checklists — the Philadelphia example is available here.
Local Energy Audits provides on-site leak detection and sealing using advanced thermal imaging tools, caulk, and spray foam./li>

Preparing for a Blower Door Test in Lincoln Park, NJ

Before conducting blower door test in Lincoln Park, NJ, we make sure all heating, cooling, and ventilation fans are switched off. Next, we conduct a quick walkthrough of the home, confirming that all exterior doors and windows are securely closed — including those to unfinished basements, garages, or any area outside the thermal envelope. With all openings sealed, we place the blower door frame and fan in a main exterior door and use it to depressurize the structure to 50 Pascals for precise testing results. When depressurization is complete, outside air flows in swiftly, allowing easy detection of leakage spots. 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. Equipped with chalk, spray foam, and weatherstripping, we can directly assist homeowners or contractors in resolving visible air leakage problems on-site. After completing sealing improvements, we retest immediately to ensure the desired blower door score is met and the home complies with efficiency standards in Lincoln Park, NJ.
