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.
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 certified experts 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.
