Blower Door Testing

Find the Leaks. Improve Comfort. Save Energy.

Sealing cracks, gaps, and openings is one of the most cost-effective ways to improve your home’s energy efficiency. The first step is identifying exactly where air is escaping. While some drafts are easy to notice, many air leaks are hidden and require a more thorough evaluation.


Air leakage can contribute to uncomfortable rooms, uneven temperatures, and higher energy bills. Before investing in major energy-efficiency upgrades, such as new windows or insulation, consider scheduling a home energy audit and blower door test. A blower door test helps pinpoint areas of air leakage and provides valuable insight into how your home is using—and losing—energy.


Schedule your home energy audit and blower door test today. We are a trusted home energy contractor proudly serving the Fox Cities and surrounding areas, helping homeowners improve comfort, efficiency, and energy savings.

Why Air Sealing Matters

  • Lower energy consumption and utility costs. 
  • Prevention of moisture condensation problems. 
  • Reduction of uncomfortable drafts caused by cold air infiltration. 
  • Determination of ventilation needs for improved indoor air quality.
