How Much to Install a Pet Door in Glass?

Ever wished your furry friend could come and go as they please without you having to play doorman? 

A pet door in glass might just be the perfect solution! Whether you have a curious cat or an energetic dog, a well-installed pet door allows them the freedom to move between indoors and outdoors with ease. But when it comes to glass doors, installation isn’t as simple as cutting a hole—you need expert precision and the right materials to ensure safety and durability.

So, how much is a pet door for dogs and for cats? Let’s break it down below!

How Much to Install a Pet Door in Glass?

Installing a pet door in a glass door requires professional expertise, as glass is delicate and needs precise cutting or full replacement. The cost of installation depends on factors such as the size of the pet door, the type of glass, and whether you are modifying an existing glass panel or replacing it altogether.

How Much Does It Cost to Install a Doggie Door?

Dog doors come in a variety of sizes to suit different breeds. The cost of installing a dog door in a glass panel typically falls between AUD 350 and AUD 1,000, depending on the following factors:

  • Size of the pet door: Larger pet doors require more complex installation, which can increase the cost. Common sizes include small (20cm x 25cm), medium (30cm x 40cm), and large (40cm x 60cm), with extra-large options for bigger breeds.
  • Cutting into existing glass vs. replacing glass: Cutting into toughened or double-glazed glass requires a specialist, and in many cases, a full replacement of the glass panel is necessary.
  • Type of glass: Standard glass is cheaper, while double-glazed or toughened glass costs more to modify or replace. Laminated glass is another option, which adds an extra layer of security and insulation.

How Much Does It Cost to Install a Cat Door or Cat Flap?

Cat doors are generally smaller than dog doors, making them slightly more affordable. The cost to install a cat door in glass ranges from AUD 250 to AUD 800, depending on similar factors:

  • Size of the cat door: While smaller than dog doors, larger cat doors for multiple pets can cost more. Typical sizes include small (15cm x 20cm) and large (20cm x 25cm), ensuring your feline friend has enough space to pass through comfortably.
  • Cutting vs. replacing the glass: If the existing glass is toughened, you may need to replace it entirely, which will increase the cost. Toughened glass cannot be cut once installed, so a new pane is required in this case. 
  • Type of glass: Double-glazed glass is more expensive to replace than single-glazed glass. Laminated glass is also an option, offering better insulation and noise reduction.

Types of Glass for Pet Door Installation

When installing a pet door in glass, choosing the right type of glass is crucial for durability and efficiency. Here are the most common types used:

  • Single-glazed glass: The most affordable option, but less durable and offers minimal insulation.
  • Double-glazed glass: Consists of two layers of glass with a sealed air gap, providing better insulation and noise reduction. This type of glass is more expensive but ideal for homes in extreme climates.
  • Toughened glass: This type of glass is heat-treated to enhance strength. It is highly durable but cannot be cut once installed, meaning a new pane must be ordered.
  • Laminated glass: Features a plastic layer between two sheets of glass, offering additional security, noise reduction, and UV protection. While pricier, it’s an excellent choice for households concerned about safety and energy efficiency.

Benefits of a Pet Door

Installing a pet door in glass offers numerous benefits for both pet owners and their furry friends:

  • Freedom for pets: Your pet can enter and exit as needed, reducing the need for you to open the door constantly.
  • Reduced accidents: Pets can relieve themselves outside instead of waiting for you to let them out.
  • Improved mental and physical health: More time outside keeps pets active and entertained.
  • Convenience: No more interrupted work or sleep to open the door for your pet.
  • Security options: Many pet doors come with lockable features to prevent unwanted intruders.
  • Energy efficiency: High-quality pet doors installed in double-glazed or laminated glass help maintain indoor temperatures, reducing energy bills.

Why Opt for Pro Installation of a Pet Door Over DIY?

While some pet owners might consider a DIY approach, installing a pet door in glass is best left to professionals. Here’s why:

  • Glass is fragile: Cutting toughened or double-glazed glass requires expert tools and knowledge. Attempting it yourself could result in cracks or breakages.
  • Precision is key: Incorrect measurements can lead to an ill-fitting door, affecting insulation and security.
  • Safety concerns: Handling glass without the right equipment can lead to injuries.
  • Warranty and insurance: Many professional installations come with a guarantee— offering peace of mind if anything goes wrong.
  • Custom solutions: Professionals can install pet doors in a variety of glass types and ensure a seamless fit without compromising the integrity of your door or window.
