How Pet Doors Could Affect Your Energy Bills

Pet doors make outside visits more convenient for homeowners and their four-legged family members, but could have negative effects on your budget. Whether you already have a pet door installed, or you’re considering adding one, it’s important to consider how the door can affect your household energy bills.

How a Pet Door Impacts Your Home’s Energy Efficiency

Heating and cooling account for almost half of the energy used in the average home, so inefficiencies, like air leaks, matter. Since a pet door creates a sizable opening in your home’s conditioned envelope, it can easily let your heated air escape in the winter, and allow hot outdoor air in when you’re cooling your home in the summer.

Focus on Efficiency When Choosing a New Pet Door

If your pet door installation is still in the planning stage, following these suggestions can help you prevent unnecessary energy waste by making it as efficient as possible from the get-go.

When you’re comparing ready-made pet doors, look for one that:

  • Is well-insulated and made of rigid materials,
  • Seals securely against the elements,
  • Is designed to function well in warm and cold weather.

Eliminate Leaks Around an Existing Pet Door

If you already have a pet door installed that you know is wasting energy, you can easily take steps to make it more efficient:

  • Remove the pet door frame from your door first, install foam weatherstripping all around the opening, then reinstall the frame and add a bead of silicone caulk around its perimeter.
  • Cover the pet door flap(s) with adhesive-backed rubber insulation cut to the right size. If possible, add magnets on each side and corner of the flap to keep the wind from blowing it open.
  • Depending on the design of your pet door, you can also install a self-adhesive brush strip all around the opening to further reduce drafts.
