How to Prevent Drafts

Invest a small amount of your time and money to fix air leaks and you'll trim your heating and cooling bills by making your home energy efficient while raising your status as a green neighbor.

Instructions

  • Step 1: Locate drafts Locate drafts in your home by feeling for cold air leaks at any opening, especially near utility connections, lighting, dryer vents, and mail chutes.
  • Step 2: Investigate joining materials Investigate joining materials for drafts at the place where building materials connect, paying special attention to windows, door frames, around chimneys and the foundation.
  • TIP: Close fireplace dampers when fireplaces are not in use to prevent drafts and reduce heat loss, trimming up to 30 percent from your annual heating costs.
  • Step 3: Seal leaks Seal air leaks you find to prevent drafts using caulk, spray foam, or weather stripping available from most home improvement stores.
  • TIP: Use caulk to prevent drafts around outside faucets, ceiling fixtures, water pipes and stationary windows. Apply weather stripping around movable windows and doors.
  • Step 4: Add attic insulation Add insulation to your attic, the main source of a home's heat loss. Make sure insulation performance is suitable for your climate.
  • Step 5: Add storm windows Add storm windows to prevent drafts, or put plastic over our windows.
  • Step 6: Seal ducts Seal easily accessed heating and cooling ducts with metal tape or mastic sealant to maximize these systems and to ensure your home is not only draft free, but also comfortable and energy efficient.
  • FACT: Sealing and insulating the shell of your house provides an average savings of 10 percent on your annual energy bill.
