Why Seal Air Leaks?
Air leaks in your home’s walls, ceiling, doors, windows, and floors can lead to higher energy bills and less comfort. Keep warm air inside in the winter and prevent heat from invading your cool, conditioned space in the summer.
According to EnergyStar, properly sealing and insulating your home can
reduce heating and cooling costs by up to 20% or cut total annual energy expenses by up to 10%. Whether you’re a DIY homeowner or working with a contractor, sealing air leaks is one of the most cost-effective ways to save energy.
