As winter rolls in, the chill in the air can find its way into your home, making it feel colder and leading to higher energy bills. Drafts are one of the main culprits of heat loss, and they can occur in places you might not even think to check. Draft-proofing your home is a simple and cost-effective way to stay warm, save energy, and improve your comfort throughout the colder months. At Royal LePage® Atlantic, we want to help you keep your home cozy and efficient this winter. Here are some of the best ways to draft-proof your house and make sure your home stays warm and snug during the winter season:

1. Seal Gaps Around Windows and Doors

Windows and doors are prime areas for drafts to sneak in. Over time, weatherstripping can wear out, and gaps can form around frames, letting cold air in and warm air escape.

  • Weatherstripping: Replace old, cracked weatherstripping around doors and windows. There are many types to choose from, including foam tape, rubber seals, and adhesive-backed strips, all of which can easily be applied to prevent drafts.
  • Caulking: Check for gaps and cracks around window and door frames, particularly if the frames are older. Caulk is a great solution for sealing these small openings and keeping the cold air out.
  • Door sweeps: Install or replace door sweeps on exterior doors. These are inexpensive and highly effective at blocking drafts at the bottom of doors.

By sealing gaps, you can drastically reduce heat loss and improve your home's energy efficiency.

2. Use Draft Stoppers or Door Snakes

Draft stoppers, also known as door snakes, are long fabric tubes that can be placed at the base of doors or windows to block drafts. These are especially useful for doors that open frequently, like patio doors or interior doors to rooms you don't need heated.

  • DIY door snakes: You can easily make your own draft stopper by filling a tube of fabric with rice, beans, or old socks. Simply place it at the bottom of any door where drafts are a concern.
  • Removable options: Choose draft stoppers that can be easily removed or replaced when you want to open a door or window for ventilation. They are a simple, non-permanent solution to draft-proofing.

These easy-to-use solutions provide an extra layer of insulation and comfort, without any major home renovations.

3. Insulate Your Attic and Crawlspaces

Many homes lose a significant amount of heat through the attic or crawlspaces. Insulating these areas is a more permanent solution to keeping your home warm during winter and preventing cold drafts from seeping in.

  • Attic insulation: Make sure your attic is properly insulated with fiberglass or spray foam insulation. Insulating your attic can save you hundreds of dollars in energy costs and help prevent cold air from entering through the roof.
  • Crawlspaces: If you have a crawlspace under your home, check for insulation and ensure that vents are sealed to prevent cold air from creeping in. You can also use foam board insulation to cover the floors and walls of crawlspaces.

Proper insulation is one of the most effective ways to keep the warm air inside your home and prevent heat from escaping through your attic or crawlspaces.

4. Add Insulated Curtains or Window Film

Windows are often the most significant source of heat loss in a home. Installing insulated curtains or window film can provide an additional barrier to cold drafts, helping to keep your living space warmer.

  • Thermal curtains: These curtains are designed to block out the cold and prevent drafts from entering through windows. Look for curtains with thermal backing or insulated materials to maximize their effectiveness.
  • Window film: Clear plastic window film can be applied to windows to create an additional insulating layer. It works by trapping air between the film and the window, providing an extra buffer against drafts.

These easy and affordable additions to your windows can make a big difference in reducing drafts and keeping your home warm.

5. Check and Insulate Your Fireplace

Fireplaces are a charming addition to any home, but they can also be a source of drafts if not properly sealed. When you’re not using the fireplace, make sure it’s tightly closed and insulated.

  • Fireplace draft stoppers: Install a chimney balloon or draft stopper to seal the flue when it’s not in use. This prevents cold air from coming down the chimney and warm air from escaping up it.
  • Damper repair: If your fireplace damper doesn’t close properly, it could be letting cold air in. Have it inspected and repaired to ensure a tight seal when the fireplace is not in use.

Taking these small steps will prevent your fireplace from becoming a pathway for unwanted drafts.

6. Seal Floor Gaps and Use Rugs

Cold air can also enter through gaps in your flooring, especially in older homes. Sealing the gaps and adding rugs or carpets can help keep your home warmer.

  • Seal floor gaps: Use caulk or expanding foam to seal any gaps in the floors, particularly along the edges of walls or between floorboards. These small cracks can be an unnoticed source of drafts.
  • Add rugs and carpets: Placing rugs or carpets on bare floors can help insulate your home and add an extra layer of warmth. This is especially helpful in areas like hallways or living rooms.

These steps will help keep your floors warmer and make your home feel cozier during the winter.

7. Use Space Heaters Wisely

If you have a room that always feels colder than the rest of your house, a space heater can be an efficient way to provide extra warmth without needing to adjust the temperature for the whole house.

  • Energy-efficient space heaters: Choose space heaters that are energy-efficient and designed for the size of the room. Look for models with timers or thermostats to prevent overheating.
  • Positioning: Make sure the space heater is placed away from drafts, such as near windows or doorways, to maximize its heating efficiency.

Space heaters can be a great tool for warming up individual rooms, especially if you’re hosting guests and need to make certain areas more comfortable.

Conclusion: Stay Warm and Cozy This Winter

Draft-proofing your home is one of the most effective ways to keep it warm and energy-efficient during the colder months. By sealing gaps, insulating your home, and using creative solutions like draft stoppers and thermal curtains, you can significantly reduce heat loss and improve your comfort throughout the winter.
