What Is Air Infiltration Sealing?
- Identifying and sealing gaps and cracks in a building’s envelope where unwanted air enters or escapes.
- A crucial step in preparing new builds or remodeled spaces for inspection and qualification for rebates.
- Reduces drafts, improves energy efficiency, and helps meet IECC code compliance.
Uncontrolled air leakage is most often identified through professional blower door testing, which measures how much air is entering or escaping the building envelope and highlights areas for targeted sealing work.
Why Air Sealing Is Important
Air leaks are one of the biggest sources of energy loss in both residential and commercial buildings. Without proper sealing:
- HVAC systems work harder
- Indoor comfort is inconsistent
- Blower door testing often fails
- Utility bills increase
Our team performs detailed insulation inspections to ensure the thermal barrier is continuous and work done during sealing delivers lasting performance. We use proven methods to seal common infiltration points like framing joints, utility penetrations, attic bypasses, and rim joists—ensuring a tight building envelope and smooth inspection process.
