How to Fix Drafts in Your House

Drafts in your house can not only make it uncomfortable but also result in higher energy bills. If you notice a chilly breeze or feel cold spots in certain areas of your home, it’s time to tackle those drafts. Here are some effective ways to fix drafts and improve the overall comfort and energy efficiency of your house.

1. Locate the Drafts: Start by identifying the source of the drafts. Common culprits include windows, doors, vents, and electrical outlets. Hold a lit candle near these areas and observe if the flame flickers, indicating an air leak.

2. Seal the Windows and Doors: Apply weatherstripping or caulk around windows and doors to seal any gaps. Use adhesive-backed foam tape for windows and door sweeps for the bottom of doors. Additionally, consider using draft stoppers or door snakes to further prevent drafts.

3. Insulate Electrical Outlets: Drafts can enter your home through electrical outlets on exterior walls. Install foam gaskets behind outlet covers to insulate against air leaks.

4. Install Window Film: Apply heat-shrink window film to single-pane windows. This plastic film creates an additional barrier against drafts and helps with insulation.

5. Add Insulation: Check your attic, walls, and basement for proper insulation. Insulate these areas using fiberglass batts, spray foam, or blown-in insulation. Adequate insulation can significantly reduce drafts and heat loss.

6. Seal Ductwork: Leaky ducts can contribute to drafts and energy loss. Inspect your ductwork and seal any gaps or cracks with foil tape or mastic sealant. This will improve airflow and prevent drafts from entering your home.

7. Use Draft Stoppers: Place draft stoppers at the base of exterior doors to block drafts. These can be purchased or easily made by sewing a long tube of fabric and filling it with rice or sand.

8. Install Storm Windows or Doors: If you have single-pane windows or old doors, consider installing storm windows or doors. These provide an extra layer of insulation and effectively block drafts.

9. Insulate Attic Access: Attic hatches or pull-down stairs can be significant sources of drafts. Add weatherstripping or foam insulation around the edges to create a tight seal.

10. Close Unused Rooms: If you have rooms that are rarely used, close the vents and keep the doors closed. This will redirect the air circulation to other areas of your home, reducing drafts in unused spaces.

11. Use Window Treatments: Heavy curtains or blinds can help insulate your windows. Close them at night to prevent drafts and open them during the day to let sunlight in and naturally warm your home.
