Ensure your property meets energy codes and maintains efficiency through expert blower door test in Margate City, 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 helps calculate air changes per hour in your property. This natural air exchange process refreshes the indoor environment with new air. Too many air changes can negatively impact efficiency, as every replacement of indoor air demands additional heating or cooling energy. Too frequent air changes can produce drafts and discomfort from leaks, while also increasing the risk of condensation, moisture, and mold. A blower door test in Margate City, NJ locates leaks and inefficiencies quickly, allowing homeowners to enhance energy performance and create a cozier living space.

What Our Clients Say

How Is A Blower Door Test Conducted?

To carry out blower door test in Margate City, NJ, exterior doors and windows are fully closed, and interior doors are left open for even air distribution in the home. A central door to the outside is selected, and an adjustable aluminum frame with a fabric cover is installed there. A calibrated fan is installed onto the frame, creating a pressure difference of 50 Pascals, comparable to a continuous 20 mph wind blowing on the home.

As the fan removes air, outside air naturally flows inside through leaks, joints, and other gaps. A precise nanometer instrument allows us to compare the pressure generated by the fan to that within the house. These readings are then converted into the total number of air changes per hour (ACH), revealing how airtight the home is and how well it performs in the NJ climate.

What Is A Passing Blower Door Test Score?

In Margate City, NJ, homes are designed to meet or exceed the 2015 International Energy Conservation Code (IECC) or the latest locally adopted standards. An acceptable blower door test result in most areas is 3 air changes per hour or less, demonstrating solid energy performance. Passing this threshold during your blower door test in Margate City, NJ ensures both energy savings and full compliance with local regulations.

Use an air barrier system such as Tyvek or Zip Sheathing and verify that each seam is properly sealed with tape.
Apply insulation of the correct R-value and make sure it fits snugly in all areas 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.
Eliminate air leaks by sealing all openings between conditioned areas and unconditioned spaces, including basements and attics.

Preparing for a Blower Door Test in Margate City, NJ

Before starting blower door test in Margate City, NJ, we turn off all heating, air conditioning, and exhaust fans in bathrooms and kitchens. Next, we check the home thoroughly to ensure all exterior openings — even those leading to garages or unfinished basements — are securely closed and within the thermal envelope. After sealing the home, the blower door fan is installed in a central exterior doorway and used to lower pressure to 50 Pascals to measure airflow and leakage effectively. Once the home is depressurized, outside air starts infiltrating more forcefully, making it easier to spot air leaks. Using a thermal imager, we locate inefficiencies by observing temperature differences in walls, ceilings, and surfaces separating conditioned and 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. We can retest right after sealing to check whether the desired blower door score has been met, ensuring full compliance with Margate City, NJ energy standards.
