Why Air Sealing Matters
Even a well-insulated home can waste energy if air leaks aren't addressed. The average home has enough gaps, cracks, and holes to equal leaving a window open year-round. Air sealing stops conditioned air from escaping and prevents outside air, moisture, dust, and allergens from entering.
Common Air Leak Locations
- Attic penetrations: Wiring holes, plumbing stacks, recessed lights, attic hatches
- Rim joists: The junction between foundation and framing — a major leak point
- Windows and doors: Gaps in weatherstripping and caulking
- Ductwork: Leaky ducts in unconditioned spaces waste 20-30% of heated/cooled air
- Electrical outlets: Especially on exterior walls
- Recessed can lights: Each unrated fixture is a direct hole in your ceiling
Our Air Sealing Process
- Assessment: We identify air leak locations using visual inspection and diagnostic tools
- Prioritize: We focus on the biggest leaks first for maximum impact
- Seal: Using caulk, spray foam, weatherstripping, and rigid materials as appropriate
- Verify: We confirm results and ensure proper ventilation is maintained
