Brrr! 🥶 Fill Those Air Gaps to Keep Your Home Warmer

When temperatures drop, even a well-heated home can feel chilly if cold air is sneaking in through small gaps and cracks. One of the most cost-effective ways to make your home feel warmer without turning up the thermostat is to seal those air leaks.

Air gaps allow cold outdoor air to enter and warm indoor air to escape. Over time, that draftiness makes rooms uncomfortable and forces your heating system to work harder. Sealing those gaps can improve comfort almost immediately.

Where to Look for Cold Air Leaks

Many homeowners are surprised by how many small openings exist in an average home. Common trouble spots include:

• Around windows and door frames
• Where plumbing pipes or vents pass through walls
• Gaps along baseboards or sill plates
• Around electrical outlet boxes on exterior walls
• In basements, crawl spaces, and utility rooms

A simple test: on a windy day, slowly move your hand around these areas and feel for drafts. You can also hold a tissue or incense stick and watch for movement.

Why Foam Sealant Works Well

Foam sealant is ideal for filling irregular cracks and gaps that caulk alone can’t handle. Once applied, it expands to fill the space, creating an airtight barrier that helps block cold air, pests, and moisture.

For smaller gaps and everyday household projects, Burton’s is featuring the DAP Home Seal Foam Sealant.

DAP® Home Seal™ is an all-purpose foam designed for small cracks and voids, suitable for both indoor and outdoor use. It can be applied in temperatures ranging from 30° to 120°F, making it practical even during colder months.

• Ideal for gaps and cracks up to 1 inch
• Blocks drafts, insects, and pests
• All-season cure for extended usability
• Reusable adapter and bonus straw for less waste
• Water-resistant
• Class 1 fire-rated
• Interior and exterior use
• Paintable and sandable once cured

Tips for Best Results

To get the most benefit from foam sealant:

• Apply a small amount—foam expands more than you think
• Wear gloves and protect nearby surfaces
• Allow proper curing time before trimming or painting
• Use foam for gaps; use caulk for thin seams and joints

Sealing air gaps won’t eliminate rising heating costs entirely, but it can noticeably improve comfort, reduce drafts, and help your home retain heat more efficiently.
