Preparing for Blower Door Testing Starts Early
To meet energy code requirements and pass blower door testing, it’s critical to address air sealing throughout the construction process. Partnering with a skilled insulation contractor can make a big difference. Proper air sealing should begin before drywall, starting with sealing around plumbing and electrical penetrations and caulking key areas during framing. All penetrations in the building envelope must be sealed—including those for utilities, plumbing, electrical, ventilation, and combustion appliances. Taking these steps early ensures your project meets airtightness standards the first time, saving time, money, and costly delays during final inspection.
