Project Overview

Make it easier to let your pet in and out of the house by installing a pet door. We’ll show you how to install a pet door into an existing door. Continue to Step-by-step instructions.

Step by Step Instructions

1 Remove the door
2 Working out how to position the pet door
3 Mark the template on the door
4 Drill holes in the door
5 Cut out the opening
6 Attach the pet door
7 Re-hang the door
  • Step 1. Remove the door

    You can install a pet door while the door is still attached to its frame, but we’ve taken ours off to make it easier. We’ve placed it onto a workbench and rested the door on some timber offcuts to avoid cutting the workbench when we use the jigsaw.

  • Step 2. Working out how to position the pet door

    Make sure the pet door is at the right height for your pet to get in and out. To do this, measure the distance from the underside of your pet’s stomach to the floor. Mark that distance from the bottom of the door at two points so that the pet door is square.

  • Step 3. Mark the template on the door

    Cut out the pet door template which is supplied in the kit. Line it up with the two marks you’ve made on the door and trace around it.

  • Step 4. Drill holes in the door

    Place masking tape around the edges of the template lines you drew on the door. This will help to protect the door when you cut it. Use a cordless drill and the right sized drill bit to drill four holes in each corner of the template that you’ve marked on the door. 

  • Step 5. Cut out the opening

    Put on your safety glasses, dust mask and ear muffs. Insert the jigsaw into one of the holes you drilled and cut out the opening for the pet door.

  • Step 6. Attach the pet door

    Place both sides of the pet door into the hole on either side of the door. Secure it to the door with the screws provided in the kit.

  • Step 7. Re-hang the door

    Re-hang the door in the door frame. Now, all you need to do is train your pet to use its new door and enjoy not having to let your pet in and out all of the time.

Please make sure you use all equipment appropriately and safely when following the advice in these D.I.Y. videos. You need to be familiar with how to use equipment safely and follow the instructions which came with the equipment. If you are unsure, you may feel it is safest to consult an expert, such as the manufacturer or an expert Bunnings team member.
