Blower Door Test in Stratford, NJ

Protect your energy investment and verify airtightness with advanced blower door test in Stratford, NJ. Our licensed professionals help homeowners, builders, and contractors identify air leaks, enhance comfort, and achieve NJ energy compliance.

What Is A Blower Door Test?

A blower door test is conducted to assess air changes per hour inside a home or structure, ensuring the right balance between air leakage and fresh airflow. 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 Stratford, NJ makes it easier to locate leaks and inefficiencies early, ensuring lasting comfort and reduced energy waste.

What Our Clients Say

How Is A Blower Door Test Conducted?

To execute blower door test in Stratford, NJ, exterior windows and doors are secured shut, while interior doors are left open to distribute air evenly. One main exterior door is identified, and an adjustable aluminum frame with a fabric panel is securely attached. 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 extracts air, exterior air begins entering the house through any unsealed spaces or cracks. Using a nanometer device, we assess how the pressure from the fan differs from the home’s natural air pressure. The data collected is translated into air changes per hour (ACH), showing the home’s airtightness and overall energy efficiency in NJ conditions.

What Is A Passing Blower Door Test Score?

In Stratford, NJ, energy efficiency standards for homes are based on the 2015 International Energy Conservation Code (IECC) or more recent updates approved by the jurisdiction. Typically, a passing blower door test result is 3 air changes per hour or lower, which indicates good energy efficiency. Meeting this level during your blower door test in Stratford, NJ supports energy efficiency and verifies that your home meets local codes.

Seal all penetrations in exterior walls using caulk or spray foam.
Ensure doors and windows are properly installed, caulked, and weather-sealed.
Close gaps and penetrations between conditioned zones and unconditioned sections like attics, basements, and crawl spaces.
Local jurisdictions frequently publish compliance checklists — the Philadelphia version can be downloaded here.

Preparing for a Blower Door Test in Stratford, NJ

Getting ready for blower door test in Stratford, NJ involves turning off all heating, cooling, and exhaust ventilation systems. We proceed with a quick home walkthrough, checking that every exterior door and window is tightly shut — including ones that lead to unfinished or unconditioned spaces outside the thermal envelope. After ensuring the home is airtight, we install the blower door frame and fan in a central exterior door and depressurize the house to 50 Pascals to record airflow and leakage data accurately. Once the structure is depressurized, outside air penetrates more actively, exposing any leaks and weak points. A thermal imager helps us identify air leakage points by revealing temperature shifts in walls, ceilings, and surfaces adjoining unconditioned areas. We come prepared with chalk, spray foam, and weatherstripping, allowing us to assist homeowners or contractors in sealing visible air leakage points on the spot. We conduct a quick retest after sealing to verify that the desired blower door score has been achieved and that your home adheres to Stratford, NJ energy efficiency codes.
