Air sealing involves sealing gaps, cracks, and leaks in your home’s envelope (walls, windows, doors, ducts, etc.) to prevent air from escaping or entering. This can lead to better energy efficiency by reducing the load on your heating and cooling systems. The primary benefits include lower energy bills, improved indoor comfort, better air quality, and reduced strain on your HVAC system, leading to longer system life.

Signs that your home may need air sealing include:

• Uneven room temperatures or drafty areas.
• High utility bills despite regular HVAC maintenance.
• Visible gaps around windows, doors, or outlets.
• Rooms that feel humid or musty, especially in areas like the attic or basement. A professional air sealing inspection can identify hidden air leaks that you might not notice.

Air sealing works by minimizing the amount of unconditioned air entering or leaving your home. This reduces the need for your HVAC system to work harder to maintain a comfortable temperature. By sealing gaps, you reduce the loss of warm air in winter and cool air in summer, making your heating and cooling more efficient and ultimately lowering your energy bills.

Yes, air sealing can result in significant savings. According to the U.S. Department of Energy, sealing air leaks can reduce energy bills by up to 20%. By preventing air from escaping, your heating and cooling systems won’t have to work as hard, resulting in long-term cost savings.

While air sealing is a long-term solution, it’s not necessarily permanent. Over time, materials can degrade, and new leaks can form. However, with proper installation, the effects of air sealing can last many years. It’s advisable to have a check-up every 3-5 years, especially after major home renovations or extreme weather events that may cause new leaks.

While both air sealing and insulation help with energy efficiency, they serve different purposes:

• Air Sealing: Focuses on blocking air leaks to prevent drafts and moisture infiltration.
• Insulation: Helps maintain the temperature by resisting heat flow, keeping the heat inside during winter and outside during summer. Air sealing and insulation work hand-in-hand to optimize your home’s energy efficiency. Air sealing prevents air from escaping through gaps, while insulation helps to regulate temperature.

The air sealing process typically begins with a thorough inspection of your home to identify leaks. Once identified, the technician will seal these gaps with the appropriate materials. The process usually takes 1-3 days depending on the size of your home and the extent of sealing needed. The technician will focus on areas such as the attic, windows, doors, and around ducts.

Yes! By sealing gaps and cracks, you reduce the influx of allergens, dust, and outdoor pollutants like pollen or mold spores into your home. This can significantly improve indoor air quality, which is particularly beneficial for people with asthma, allergies, or respiratory issues. Additionally, reducing moisture infiltration can help prevent mold growth in the home.

Yes, air sealing can help reduce noise by closing the gaps that allow sound to travel between rooms or through walls. While insulation is the primary material used for soundproofing, air sealing complements it by preventing sound leaks through gaps and cracks, especially around windows and doors.

By sealing air leaks, your heating and cooling system doesn’t have to work as hard to maintain a comfortable temperature. This can lead to a more efficient HVAC system, reducing wear and tear and extending its lifespan. Additionally, air sealing can help maintain consistent temperatures throughout your home, eliminating hot or cold spots.
