Blower Door Test in Folsom, NJ

Detect hidden air leaks and improve efficiency with professional blower door test in Folsom, 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. Excessive air changes force constant reheating or recooling, driving up energy use and reducing overall home efficiency. Excessive air circulation may cause drafts, discomfort from leaks, and indoor problems like condensation, mold, and moisture damage. A blower door test in Folsom, NJ helps uncover these issues early, enabling homeowners and builders to detect air leaks, enhance energy efficiency, and ensure a more comfortable, long-lasting home.

What Our Clients Say

How Is A Blower Door Test Conducted?

To complete blower door test in Folsom, NJ, all exterior openings are sealed, and interior doors are kept open to ensure equal airflow throughout the property. Technicians select one central exterior door and install an adjustable aluminum frame along with a fabric panel for 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 air is drawn out by the fan, it causes outdoor air to infiltrate through existing leaks and gaps in the structure. A sensitive nanometer helps us measure and compare the pressure created by the fan with the interior 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?

Homes in Folsom, NJ are typically required to follow the 2015 International Energy Conservation Code (IECC) or the most recent version adopted locally. To meet efficiency standards in most areas, homes should record 3 air changes per hour or less on a blower door test. Achieving this goal during your blower door test in Folsom, NJ promotes energy savings and demonstrates adherence to local building rules.

Why Do I Need A Blower Door Test?

The State of NJ, together with many cities and counties, enforces the IECC (International Energy Conservation Code), which calls for blower door test on new or renovated residential properties. We often work with home builders, contractors, and homeowners requiring blower door test in Folsom, NJ to meet local energy codes and obtain permit approval.

  • Install an effective air barrier, for example Tyvek or Zip Sheathing, and make certain all seams are sealed with durable tape.
  • 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.
  • Properly seal all connections between conditioned and unconditioned zones, including basements, crawl spaces, and attics.

Preparing for a Blower Door Test in Folsom, NJ

Preparation for blower door test in Folsom, NJ begins with switching off the HVAC system, as well as any bathroom and kitchen exhaust fans. Next, we inspect each room to confirm all exterior doors and windows are properly closed — including any leading to garages, basements, or other spaces beyond the thermal envelope. Once all openings are sealed, we place the blower door frame and fan in a central exterior door. The fan then lowers the pressure to 50 Pascals for precise leakage measurement. Once depressurization occurs, outdoor air enters the home more aggressively, revealing leaks more clearly. 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. Our team provides on-site repair using chalk, spray foam, and weatherstripping, working with homeowners or contractors to fix visible air leakage problems. We can retest right after sealing to check whether the desired blower door score has been met, ensuring full compliance with Folsom, NJ energy standards.
