Air leaks in homes can significantly impact indoor air quality, insect and pest ingress, and energy efficiency:
1. Indoor air quality: Air leaks can allow outdoor pollutants, such as dust, pollen, car exhaust, and industrial pollutants, to enter the home, worsening indoor air quality. This can be especially problematic for individuals with allergies, asthma, or other respiratory issues. In addition, moisture can also enter through leaks, potentially leading to mould growth and further degrading air quality.
2. Insect and mouse ingress: Gaps and cracks in a home’s exterior can provide easy entry points for insects and other pests. Sealing air leaks helps to close off these entryways, preventing pests from entering the home and causing potential health-related issues or damage to the property.
3. Energy efficiency: Air leaks can substantially impact a home's energy efficiency. Leaks allow warm air to escape during the winter and enter during the summer, which forces heating and cooling systems to work harder to maintain comfortable indoor temperatures. This additional work results in higher energy consumption and increased utility bills.
Addressing air leaks is important for maintaining a comfortable, healthy, and energy-efficient home. It involves identifying and sealing gaps and cracks around windows, doors, and other entry points with caulking, weather stripping, and sometimes more substantial repairs or insulation improvements.
