Attic Air Sealing

What This Service Involves

Even a deep layer of insulation underperforms when air leaks let heated indoor air pour into the attic. We locate and seal top plates, penetrations, recessed lights, and the attic hatch so the ceiling plane becomes airtight. In our climate, stopping that airflow also prevents warm moisture from condensing on the cold roof deck and feeding mold. Air sealing is the essential companion to insulation and one of the most cost-effective efficiency upgrades.

Benefits

Stops costly heated-air leakage; Prevents attic condensation and mold; Boosts the real performance of insulation; Improves comfort and reduces drafts; Frequently qualifies for utility incentives

Our Process

1) Diagnose leak locations across the ceiling plane; 2) Seal penetrations, top plates, and fixtures; 3) Insulate and gasket the attic access hatch; 4) Verify tightness before adding insulation

What Affects the Cost

Attic size and number of penetrations; Complexity of framing and fixtures; Materials such as foam and fire-rated sealant; Access and working clearance; Coordination with insulation work

Best Time of Year

Air sealing is ideal in fall before heating season, though it delivers value in any season.
