Why Air Sealing Your Attic Before Insulating Matters

At Dave Hoh’s Home Comfort & Energy Experts, we believe in the science behind comfort. As a BPI-certified team, we take pride in educating homeowners on why proper air sealing should always come before insulating your attic.

As colder weather arrives and you start layering up, remember—you shouldn’t have to feel uncomfortable inside your own home.

During every attic inspection, we look for clear signs of air leaks. Dust or dark streaks on insulation often indicate air movement, as escaping air carries dirt through gaps and cracks. Our team carefully pulls back insulation to check for leaks around pipes, vents, chimneys, wiring, and top plates. Every small gap adds up—and collectively, these leaks can be like leaving a window open four to six inches all year long.

This wasted air makes your home harder to heat or cool, forcing your HVAC system to work overtime and driving up energy costs. By identifying and sealing these leaks, we stop conditioned air from escaping and improve your home’s overall comfort and efficiency.

We always take time to talk with homeowners about drafty rooms, uneven temperatures, or high energy bills, as these are common signs of attic air leaks.

At Dave Hoh’s Home Comfort & Energy Experts, we offer free home evaluations throughout Monmouth and Ocean County, NJ. Our BPI certification means we follow proven building science standards to seal your home properly—using professional-grade foam sealants to close gaps, eliminate drafts, and prepare your attic for insulation. Once the attic is airtight, insulation can truly do its job—keeping warmth in and energy waste out.
