Pre-Installed Pet Doors

  • Secure, pre-installed dog and cat doors for maximum ease of installation
  • Storm door and sliding patio door options to fit your insulation needs

If you need a new door along with your pet door, doors with dog doors already installed are the way to go. We have two different categories of pre-installed pet door units: those in sliding glass doors, and those in storm doors with built-in dog doors (these are different from regular exterior doors with dog doors built-in). Browse our full selection of pre-installed pet doors and read more below to learn about the benefits of this installation style.
