Ways to Stop Pet Door Drafts in Winter Months

According to Green America, drafty windows and doors can increase your heating bill during the winter months by around 20 percent. You don’t need to be a mathematician to know how that could take big bucks out of your pocket every month. However, there’s another type of door that can contribute to heat loss: your pet door. Yes, your pet door – you know the flap that you have installed in your back door so that Rover can go in and out of the house as he so pleases? Most pet doors are just that: flaps of plastic that work about as well as a poncho at keeping the cold out and the heat in, which leads to serious pet door drafts in winter.

What You Can Do to Stop the Drafts

When you go to assess your windows and doors for drafts, don’t forget about the pet door. Here are some ways to stop pet door drafts in the cold winter months:

  • Size up your surroundings. Depending on your home’s layout, stopping those pet door drafts may not even require reinstalling your pet door. For instance, many older homes are designed so that the back door is positioned between the dining room and kitchen, and can be closed off from the two rooms by doors. If you intend to use your pet door during the winter months and have a similarly designed home, just make sure that the appropriate doors are shut when the pet door is in use, so the drafts stay confined around the back door area. You’ll still likely notice a slight increase in your heating bill during the winter, but it won’t be an alarming increase.
  • Seal off the pet door. While this might not be convenient for your dog, temporarily sealing the pet door will reduce the pet door drafts in winter. Again, you’ll have to let Rover outside to do his business yourself if your pet door is disabled, but the minor inconvenience may be more desirable than the spike in your energy bill.

Thermo Panel 3e is the best pet door for drafts due to the design of the Endura FlapBuy a more efficient flap or pet door. Sometimes the answer to how to winterize dog door installations is to start over.  Just as dual-pane windows are much more energy efficient than single-pane windows, the same concept applies to pet doors. There is already a dual-pane insulated glass panel pet door, known as the “Thermo Panel” on the market. It tends to be more expensive than a conventional pet door, but as with dual-pane windows, the up-front investment pays for itself in energy savings over time.

In short, following these suggestions could decrease your loss of heat in winter months, and help keep your energy bill expenses in check, in turn saving you money.

    Our pet door is installed right next to the kitchen so it is always freezing in the mornings. Thanks for the tips!

    We have the electric doggy door and it dose not work well in the winter. When it gets down to 30 degrees it won’t close right away and will go up and down until it finally closes. I do love the doggy door but wish you could make it better for winter use.

    Even though our dog door is in our laundry room with another door to close going into the living room I always do the following in winter (Maryland). Buy fleece (on sale) cut to fit door which is metal and does have a window. I double layer the fabric and use strong magnets to hold up fabric. I cut out (only on three sides) the dog door and use a magnet to hold up the fabric when I want the dogs to use door I bring down the fabric at night and use the metal security panel up against the door at night to help block air from coming in. I also use blankets to strop drafts at the bottom of door. This year some of my magnets on the flaps came off and it was way to cold glue them back on so I put some insulation form that is flat with a sticky back on the metal door frame to stop drafts. When the weather warms up I just remove the fabric and use again next year. You would be surprised to learn the different ways of using fleece to keep your home warm or cool.
