Sealing Drafts: A Simple Way to Enhance Your Home’s Comfort and Efficiency

Sealing Drafts: A Simple Way to Enhance Your Home’s Comfort and Efficiency 

As a real estate agent, I often remind homeowners that small improvements can make a big difference, especially when preparing a property for sale. One such improvement is sealing drafts around windows, doors, and other areas. Not only does this enhance energy efficiency, but it also creates a more comfortable living environment—something potential buyers will notice and appreciate.

Why Sealing Drafts Is Important

Drafts occur when gaps or cracks allow outside air to enter your home and indoor air to escape. These leaks can:

• Increase Energy Bills: Heating and cooling systems work harder to compensate for air loss.
• Reduce Comfort: Drafty spaces feel colder in winter and hotter in summer.
• Contribute to Moisture Issues: Gaps can let in rain or condensation, potentially causing damage.
• Impact Noise Levels: Drafts can allow outside noise to seep into your home.

By addressing drafts, you’re improving your home’s efficiency, comfort, and overall value.

Common Sources of Drafts

• Windows and doors
• Electrical outlets
• Baseboards and trim
• Attic hatches
• Chimneys and vents

Step-by-Step Guide to Sealing Drafts

1. Identify Drafty Areas

To find drafts:

• Use Your Hands: Feel for cool air near windows, doors, and other potential problem areas.
• Perform a Candle Test: Hold a lit candle near suspected draft points. If the flame flickers, you’ve found a draft.
• Try a Thermal Leak Detector: These devices help pinpoint air leaks.

2. Gather Your Supplies

You’ll need:

• Weatherstripping
• Caulk (and a caulking gun)
• Foam sealant
• Door sweeps
• Draft stoppers or foam gaskets for outlets
• Utility knife or scissors

• Weatherstripping: Install adhesive-backed weatherstripping around window and door frames to create a tight seal.
• Caulking: Apply caulk to seal gaps around stationary parts of windows and doors. Be sure to use weatherproof caulk for exterior gaps.
• Door Sweeps: Attach a door sweep to the bottom of exterior doors to block drafts.

4. Insulate Outlets and Switches
Drafts can seep in through electrical outlets and light switches, especially on exterior walls. Install foam gaskets behind outlet and switch covers to block air leaks.

• Attic Hatch: Install weatherstripping around the attic hatch and use an insulated cover if necessary.
• Chimney: Use a chimney balloon or flue seal to block drafts when the fireplace is not in use.

Maintenance Tips

• Inspect your home for drafts at least once a year, preferably before winter.
• Replace weatherstripping and caulking as needed to maintain a strong seal.
• Clean and maintain sealed areas to ensure they remain effective.

Benefits for Home Sellers

Sealing drafts not only reduces energy bills but also makes your home more appealing to buyers. Energy efficiency is a top priority for many buyers, and demonstrating that your home is well-maintained can give you a competitive edge.
