Dog Door FAQs
What Types of Doors Can Dog Doors Be Installed In?
We install dog doors in a range of materials, including glass, timber, steel, and screen doors. We also offer installation in double-glazed glass, although only certain products are suitable.
How High Should a Dog Door Be Installed?
The bottom of the door should generally sit just below your dog’s chest. We’ll help determine the perfect height based on your dog’s leg length and your door style.
I’m Installing My Own Dog Door – What Size Should I Get?
Measure your dog’s shoulder height and width before choosing a size. The door should be large enough for your dog to pass through without crouching or squeezing.
Does the Dog Door Have to Be Installed in a Door?
Not at all. We can install dog doors in fixed glass panels, sliding glass doors, or even in walls, giving you flexible options that suit your space.
Are Large or Extra-Large Dog Doors Secure?
Yes. We offer lockable flaps and microchip-activated dog doors that only open for your pet. This helps prevent unwanted animals—or people—from gaining access.
Do You Offer Microchip Dog Doors?
Yes. If needed, we can install microchip activated cat doors for smaller dogs. We don't offer microchip options for larger dogs.
Will a Dog Door Affect My Home's Energy Efficiency?
Modern dog doors are designed with weather seals and durable flaps to minimise drafts and heat loss. We install quality products that help keep your home comfortable year-round.
Can You Install a Dog Door in a Sliding Glass Door?
Yes, we can install pet doors in single-glazed and double-glazed sliding doors, but this often involves replacing the glass with a toughened panel that includes the pet door.
What If I Have More Than One Dog?
No problem. We’ll recommend a door size that suits your largest dog while still allowing smaller pets to use it easily.
How Long Does a Dog Door Installation Take?
Most installs are completed in one visit. Once your custom glass panel is ready, installation typically takes around 1–2 hours.
