What Is A Blower Door Test?

A blower door test is performed to record air changes per hour in buildings, confirming that fresh air regularly replaces stale indoor air. Too many air exchanges make heating and cooling systems work harder, increasing energy consumption and lowering efficiency. Excessive air changes often cause drafts, discomfort, and humidity-related issues such as condensation and mold growth inside the home. A blower door test in Newark, DE 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 perform blower door test in Newark, DE, all exterior doors and windows are tightly sealed, while interior doors remain open to promote balanced airflow throughout the home. A central exterior door is picked, where the technician fits an adjustable aluminum frame and fabric panel for airtight testing. A calibrated fan mounted on the frame reduces the home’s pressure to 50 Pascals, simulating the force of a continuous 20 mph wind.

As the fan removes air from inside, exterior air flows in through leaks and gaps in the building envelope. A nanometer is used to detect and compare the pressure created by the fan with the air pressure inside the structure. The pressure data is turned into air changes per hour (ACH), a measure of how efficiently and tightly the home is sealed in DE.

What Is A Passing Blower Door Test Score?

In Newark, DE, energy efficiency standards for homes are based on the 2015 International Energy Conservation Code (IECC) or more recent updates approved by the jurisdiction. To meet efficiency standards in most areas, homes should record 3 air changes per hour or less on a blower door test. When your blower door test in Newark, DE meets this requirement, you ensure energy efficiency and maintain compliance with building codes.

Why Do I Need A Blower Door Test?

Throughout DE, the IECC (International Energy Conservation Code) is followed, making blower door test compulsory for new and renovated homes. Our certified technicians assist home builders, contractors, and homeowners with blower door test in Newark, DE to meet energy requirements and wrap up permit approvals. If any part of the HVAC system or ductwork sits beyond the building’s thermal envelope, a duct leakage test may be required. Learn more about energy code compliance.

Through blower door test in Newark, DE, homeowners can easily find leaks. When the fan reduces internal pressure, air movement through problem areas becomes noticeable, offering chances to save energy. Although it’s a short process, a blower door test produces a long-lasting impact by improving comfort and lowering energy costs throughout DE’ climate extremes.

How To Pass A Blower Door Test:

Anticipate potential air leaks before testing begins.
Use an air barrier system such as Tyvek or Zip Sheathing and verify that each seam is properly sealed with tape.
Fit insulation with the correct R-value and make sure it’s installed without voids across the entire building envelope.
Seal all penetrations in exterior walls using caulk or spray foam.
Ensure doors and windows are properly installed, caulked, and weather-sealed.
Close any gaps connecting conditioned and unconditioned spaces, such as those leading to basements, attics, or crawl spaces.
Many local building offices offer a step-by-step checklist to confirm compliance — view the Philadelphia sample here.
Local Energy Audits identifies and repairs leaks on-site using thermal imaging tools, caulk, and high-quality spray foam./li>
Over 90% of cases result in a passing score within two hours, along with complete permit documentation.

Preparing for a Blower Door Test in Newark, DE

To prepare for blower door test in Newark, DE, we start by turning off the heating and cooling system, along with all bathroom fans and kitchen 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 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 depressurization is achieved, the inflow of outside air intensifies, making air leaks easier to find and fix. A thermal imager allows precise detection of problem areas by mapping temperature contrasts in walls, ceilings, and surfaces facing unconditioned areas. We bring the tools and materials—chalk, spray foam, and weatherstripping—to work with homeowners or contractors in fixing visible air leakage issues immediately. 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 Newark, DE.

Blower Door Test for Contractors in Newark, DE

For contractors arranging blower door test in Newark, DE, most homes with professional insulation can handle small air leakage issues during the test itself. Using materials like chalk and spray foam, small leaks or gaps can typically be sealed right away during the test.
