Signs Your Home Has Air Leaks

Some homes are more tightly constructed than others. How do you know if yours could use an insulation performance boost? Here are some common indicators:

• Drafty rooms: Feeling unpleasant drafts while the windows and doors are closed suggests air leaks.
• High energy bills: Inexplicably high heating or cooling costs may indicate your HVAC system is compensating for escaping air.
• Uneven temperatures: Noticeable temperature differences between rooms may result from localized air leaks.

Common Areas for Air Leaks

All buildings tend to leak in the same places. Pay close attention to these particular spots:

• Attic floor: Gaps around plumbing vents, recessed lighting, and the attic hatch are common culprits.
• Windows and doors: Cracks between the frame and the wall and gaps when the window or door closes can allow air to pass through.
• Exterior wall penetrations: Electrical outlets, switch plates, vent openings, and utility lines can be hidden sources of air leaks.
• Basement: The junction where the concrete foundation meets the wood framing is a common leakage point.

Why Air Seal Before Installing New Insulation?

If you’re thinking of adding or upgrading your home’s insulation, seal the air leaks first. Insulation slows heat transfer but doesn’t stop air movement, meaning conditioned air can still escape. Taking the time to seal your home offers these benefits:

• Improved insulation effectiveness and enhanced energy efficiency
• Lower utility bills resulting from reduced heat loss
• More consistent indoor temperatures across all rooms
• Protection against mold growth and structural damage caused by moisture infiltration
• Less wear and tear on HVAC equipment for a longer lifespan

Tips for Sealing Attic Floor Penetrations

The attic is a common place to retrofit existing homes with more insulation. But first, follow these air-sealing tips to enhance insulation performance:

• Identify leaks: Remove existing insulation, if present, and check for gaps around anything that penetrates the floor, including plumbing vents, electrical wiring, chimney chases, and recessed light fixtures.
• Use appropriate materials: Caulk is suitable for small gaps less than 1/4 inch wide, while expanding spray foam is better for larger openings.
• Seal recessed lights: Install airtight, insulated covers over recessed lights to prevent air leakage.
• Seal the attic hatch: Insulate the attic access door and attach weatherstripping to create an airtight seal.
