Air sealing is the foundation of any effective attic energy upgrade, and it's a step many insulation companies skip. At Montebello Attic Insulation, we treat air sealing as a separate, dedicated service because no amount of insulation can compensate for unchecked air movement. Warm air in winter and hot attic air in summer travel through gaps around recessed lights, plumbing stacks, HVAC boots, and top plates — and those leaks drive up your energy bills significantly.
Our technicians use canned spray foam, two-component foam, and fire-rated caulk to seal every identifiable bypass in your attic floor. We pay special attention to areas around the attic hatch, interior wall top plates, and any ductwork penetrations. In older Montebello homes, these gaps can add up to the equivalent of leaving a window open year-round. Sealing them properly before adding insulation ensures that the insulation can do its job as designed.
Air sealing is frequently paired with our attic insulation installation service for the greatest energy impact. Many customers report noticeably more consistent room temperatures and reduced HVAC run times within days of completing both services together.
