Blower Door Test in Westville, NJ

Verify your home’s airtightness and meet energy-efficiency standards with a professional blower door test in Westville, NJ. Our experts help homeowners, builders, and contractors pinpoint air leaks, improve efficiency, and comply with NJ building energy standards.

What Is A Blower Door Test?

A blower door test calculates the rate of air changes per hour in a property, verifying that proper ventilation keeps air fresh and clean. If air changes happen too often, it forces your system to reheat or recool the air repeatedly, wasting energy and lowering performance. 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 Westville, NJ detects early-stage air leaks, enabling effective energy use and a more durable, comfortable living environment.

What Our Clients Say

How Is A Blower Door Test Conducted?

When performing blower door test in Westville, NJ, the technician ensures all exterior doors and windows are sealed and interior doors are open for steady air movement. A single main exterior door is fitted with an adjustable aluminum frame and attached fabric panel to begin the setup. A calibrated fan is fitted into the frame and depressurizes the home to 50 Pascals, mimicking the pressure caused by a 20 mph wind.

As air is drawn out by the fan, it causes outdoor air to infiltrate through existing leaks and gaps in the structure. Using a nanometer, we accurately compare the pressure difference between the fan output and the home’s interior. 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?

Residential buildings in Westville, NJ must adhere to the 2015 International Energy Conservation Code (IECC) or newer versions adopted by city or county regulations. In many locations, a result of 3 air changes per hour or less is required to verify the home’s energy efficiency level. Achieving compliance in your blower door test in Westville, NJ helps improve energy efficiency and meet all local code mandates.

How To Pass A Blower Door Test:

Anticipate potential air leaks before testing begins.
Choose an appropriate air barrier, like Tyvek or Zip Sheathing, and ensure all seams are accurately and securely taped.
Use insulation of the correct R-value and confirm that it’s tightly installed throughout every section 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.
Make sure to seal all separations between conditioned and unconditioned areas, including crawl spaces, basements, and attics.
Many local building offices offer a step-by-step checklist to confirm compliance — view the Philadelphia sample here.

Preparing for a Blower Door Test in Westville, NJ

Before conducting blower door test in Westville, NJ, we make sure all heating, cooling, and ventilation fans are switched off. 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. Once all doors and windows are sealed, we set up the blower door system in a centrally located exterior door and reduce air pressure to 50 Pascals to evaluate leakage. After the home is depressurized, incoming outdoor air becomes more intense, making leak points easy to locate. Using a thermal imager, we easily locate air leaks by noting temperature differences on walls, ceilings, and other surfaces adjacent to unconditioned spaces. Our technicians arrive with chalk, spray foam, and weatherstripping materials, ready to work with homeowners or contractors to fix visible air leakage problems right away. After sealing the leaks, we can immediately run another test to verify that the desired blower door score meets the local efficiency standards for homes in Westville, NJ.
