Air leaks are one of the biggest culprits of energy inefficiency in homes, allowing conditioned air to escape and outside air to infiltrate. This not only drives up energy bills but also creates uncomfortable indoor conditions. By addressing air infiltration, you can maintain a consistent indoor temperature—keeping your home warmer in the winter and cooler in the summer. Beyond temperature control, air sealing reduces outdoor noise, creating a quieter and more peaceful living environment.

Air sealing is the process of identifying and eliminating air leaks in your home. These leaks often occur in less obvious areas and can go unnoticed for years. Proper air sealing not only improves energy efficiency but also enhances overall comfort and reduces wear and tear on your heating and cooling systems. Below are the key steps typically involved in a thorough air sealing project:

*Seal Existing Insulation Gaps: Cracks or openings in insulation are sealed to stop unwanted airflow. This step ensures the insulation performs effectively.

*Caulk Wall, Ceiling, and Floor Joints: Air leaks at structural joints are sealed with caulk to create a continuous air barrier.

*Seal Around Plumbing, Wiring, and Ductwork: Penetrations for plumbing, electrical wiring, and ductwork are common sources of air leaks. These are sealed with caulk or expanding foam.

*Weatherstrip Doors and Windows: Adding weatherstripping to doors and windows ensures tight seals, preventing drafts and energy loss.

*Install Door Gaskets: Pliable gaskets are installed at the bottom of exterior doors and thresholds to block air movement.

*Fill Larger Gaps: Expanding foam is used to seal larger gaps around baseboards, portals, and other areas.

*Use Foam Gaskets Behind Outlet Covers: Foam gaskets are placed behind wall-mounted outlets and switch plates to reduce air leakage in these often-overlooked areas.

*Seal Around Heat Sources: Fire-resistant materials, such as sheet metal or furnace cement caulk, are used to seal air leaks around furnaces, water heaters, and chimneys.

Fireplaces, while charming, are a major source of air leaks. Homeowners can minimize these leaks by keeping the flue damper closed when the fireplace isn’t in use. For added insulation, consider installing a fireplace flue plug or an inflatable chimney balloon.

To ensure your home is as airtight as possible, it’s recommended to hire a professional for a comprehensive energy efficiency assessment. This process identifies hidden air leaks and provides tailored solutions to enhance your home’s energy performance.

Proper air sealing not only saves money on energy bills but also improves comfort, reduces noise, and enhances the longevity of your HVAC systems. Investing in professional air sealing services is a smart step toward a more energy-efficient and comfortable home.
