You can install a pet door through a wall. The PlexiDor dog doors and cat door are available for door or wall installation. The door kit makes it easy to install the pet door through a standard house door. A somewhat handy person can do this themselves and it doesn’t take long.

The house door isn’t always the best place for the pet door – sometimes a wall fits better. The PlexiDor wall kits can be installed in cement, stud, brick or block walls up to 12 inches thick. The kits come with an aluminum tunnel to connect the interior and exterior frame.

When you install a pet door through a wall it can be trickier than installing through a door – it is more difficult to make a hole in the wall than through a door. (An important tip is cutting from the outside – keep the mess outside the house!) You also need to check if it’s a load-bearing wall or not.

This video shows how to install a PlexiDor through a door and through different forms of walls. It begins with installing through a door. Wall installations start around 9 minutes in and will go through the installation process through different wall materials.
