Replacement parts for pet doors are available. Flaps being the most common. Security doors, magnets and locks my also be available.
When replacing flaps, we need the measurement of the flap itself not the measurement of the frame. Also make note of any words or logos on the flap.
Even if your door is old and dirty a new flap can bring it back to life. If your frame of the door is plastic, just make sure it is intact and has no cracks. Most dog doors have aluminum frames and are plenty durable to have the flaps changed out multiple times
You can email us a picture of the flap to help determine which brand it is or you can text message me a image as well.
