Air Sealing

• In addition to insulating your home, air sealing the shell of your home (including its outer walls, ceiling, windows, doors, and floors) is often the most cost effective way to improve energy efficiency and comfort. 
• ENERGY STAR estimates that a homeowner can save up to 20% on heating and cooling costs (or up to 10% on their total annual energy bill) by sealing and insulating.
• Many air leaks and drafts are easy to find because they are easy to feel — like those around windows and doors. 
• Holes hidden in attics, basements,and crawlspaces are usually bigger problems. Sealing these leaks with caulk, spray foam, or weather stripping will have a great impact on improving your comfort and reducing utility bills.

Visit our interactive energy house on our website to see where air sealing is most commonly done.

Although air sealing is important, air sealing alone does not replace the need for proper insulation throughout your home, which reduces the flow of heat from a warm space to a cool space.

Our team employs trained HERS raters to determine the air sealing and other upgrades needed to ensure a home is not wasting energy, and saving a homeowner money.
