What Is Air Sealing?
Air sealing is the process of identifying and closing gaps, cracks, and penetrations that allow air to move in and out of your home.
Even a well-insulated home can lose significant energy through hidden air leaks. Sealing these leaks helps create a tighter building envelope, allowing your insulation and HVAC system to perform more effectively.
Common Air Leaks We Seal
Our air sealing services include:
Attic bypasses and penetrations
Plumbing and wiring penetrations
Recessed lighting fixtures
Exhaust fan openings
Attic hatch openings
Rim joists and band joists
Crawl space penetrations
Basement air leaks
Gaps around ductwork
Every home is different, which is why we perform a thorough inspection before recommending solutions.
Benefits of Professional Air Sealing
Lower Energy Bills
Air leaks force your heating and cooling system to work harder. Sealing these leaks can help reduce energy waste and lower monthly utility costs.
Improved Comfort
Air sealing helps eliminate drafts and maintain more consistent temperatures throughout your home.
Better Indoor Air Quality
Reducing unwanted air movement can help limit dust, allergens, and outdoor pollutants entering your living space.
Increased HVAC Efficiency
A tighter home means your HVAC system doesn’t need to work as hard to maintain comfort.
Helps Keep Pests Out
Many of the openings used by air leaks can also become entry points for rodents and insects.
Air Sealing & Insulation Work Best Together
Many homeowners focus only on adding insulation. However, insulation performs best when air leaks have already been addressed.
For this reason, Xanvria often recommends air sealing before:
Air sealing and insulation together create the most effective energy-saving system.
