Air Sealing Services in Louisville, KY
Air leaks are one of the biggest causes of drafts, uneven temperatures, and wasted energy. Liberty Insulation KY provides professional air sealing to help reduce leakage in attics, crawlspaces, and other common problem areas—supporting better comfort and efficiency year-round.
Common Places Homes Leak Air
Many air leaks are hidden. We focus on the spots that commonly cause drafts and energy loss—especially in older homes. Air sealing pairs well with attic insulation, crawlspace insulation, and spray foam (when appropriate).
Attic Penetrations
Gaps around lights, wiring, plumbing vents, and attic hatches can leak conditioned air.
Basement & Crawlspace Leaks
Rim joists and crawlspace openings can be major draft sources—especially in winter.
Room-to-Room Imbalance
Leaks can cause hot/cold spots, making HVAC work harder to keep temperatures stable.
Humidity Pathways
Air movement can carry moisture into building cavities, increasing comfort and air quality issues.
HVAC Loss
Leaky homes often waste heated/cooled air—air sealing can help keep conditioned air where it belongs.
Seal + Insulate
Air sealing is most effective when combined with proper insulation levels and good ventilation practices.

Air Sealing FAQs
Quick answers to common air sealing questions.
Does air sealing really reduce energy bills?
Air sealing can help reduce heating/cooling loss by limiting unwanted airflow. Results vary by home and leakage level.
Is air sealing the same as insulation?
No. Air sealing stops air movement through gaps/cracks. Insulation slows heat transfer. They work best together.
Where do most homes leak air?
Common areas include attic penetrations, rim joists, crawlspaces/basements, and openings around plumbing or wiring.
