Blower Door Testing in Gypsum, CO

Delivering airtight, energy-efficient homes and buildings since 1997, InsulVail partners with homeowners and builders across Summit, Eagle, Garfield, and Pitkin Counties to diagnose and seal hidden air leaks using industry-standard blower door testing.

What Is a Blower Door Test?

A blower door test is a diagnostic procedure that measures the airtightness of a building’s envelope. A calibrated fan is mounted in an exterior doorway to create a pressure difference, either drawing air out to induce negative pressure or blowing air in to create positive pressure. As the house pressurizes or depressurizes, the equipment records airflow rates, pinpointing gaps, cracks, and leaks that drive energy loss and moisture intrusion.

Frequently Asked Questions

Do I need a blower door test?

While new construction codes often require verification of airtightness, blower door testing is equally valuable for existing homes, energy retrofits, or pre-sale inspections to uncover hidden leaks and optimize performance.

What’s the difference between calibrated and uncalibrated tests?

Calibrated blower doors quantify total leakage (CFM50), enabling you to demonstrate code compliance and measure improvements. Uncalibrated units only locate leaks without providing an airtightness metric.

How should I prepare my home for testing?

Close all exterior doors and windows, open interior doors, seal fireplace dampers, and ensure wood or pellet stoves are cold. Our team will guide you through every step to guarantee accurate results.

How long does the test take?

Most tests, including setup, diagnostics, and teardown, are completed within 60–90 minutes, with a comprehensive report delivered the same day.
