Dog Door Installation Done Right: What Every Homeowner Needs to Know
A well-installed dog door gives your dog the freedom to come and go while giving you one less thing to worry about. No more scratching at the back door. No more interrupted meetings. No more acting as your dog’s personal doorman.
However, not all dog door installations deliver the same result.
A poorly installed dog door can create drafts, affect security, damage expensive doors, and leave your dog reluctant to use it. That’s why choosing the right dog door and the right installer matters.
At Pet Doors Ontime, we install dog doors into glass, double glazing, timber doors, and security screens throughout Australia. Over the years, we’ve learned that the best installations start with good advice, accurate measuring, and choosing the right product for the job.
What Should a Professional Dog Door Installation Include?
Many homeowners assume dog door installation simply involves cutting a hole and attaching a frame.
In reality, a professional installation involves much more.
First, the installer should assess your home and identify the best location for the pet door. While the back door often seems like the obvious choice, another location may provide easier access, a cleaner finish, or a better outcome for your dog.
Next, the installer should help you select the right pet door.
This step is critical because not every pet door suits every surface. Some pet doors work brilliantly in timber doors but perform poorly in glass. Others suit security screens but are too bulky for sliding doors.
Most importantly, the pet door needs to suit your dog.
Before choosing a model, we recommend reading our guide on How to Choose the Right Pet Door Size. Choosing the wrong size remains one of the most common mistakes homeowners make.
Where Can You Install a Dog Door?
One of the biggest misconceptions about dog door installation is that every surface can be treated the same way.
However, the installation process changes significantly depending on the material.
Dog Doors in Timber Doors
Timber doors remain one of the most popular and affordable installation options.
A solid timber door provides excellent structural support and can accommodate everything from small dog doors to extra-large pet doors for Labradors, Golden Retrievers, and German Shepherds.
Even so, accurate placement still matters. If the opening sits too close to a rail or stile, it can affect both the appearance and strength of the door.
If you’re considering a timber installation, read our guide to Timber Door Pet Doors: Pros, Cons & Costs.
Not sure whether your door is solid or hollow? Our article Can You Install a Pet Door in a Hollow Core Door? explains what homeowners need to know before cutting into their door.
Dog Doors in Security Screens
Security screens require specialised products and installation techniques.
Unfortunately, many pet doors sold online are not designed for security screens. As a result, poor installations can weaken the screen, affect appearance, and reduce durability.
For most security screen installations, we recommend products such as the Hakuna Super Tough Pet Door because it combines excellent strength, weather resistance, and a slim profile that works well with sliding screen doors.

Dog Doors in Glass
Glass installations require specialist knowledge.
Unlike timber, installers cannot cut a hole into existing toughened safety glass. Instead, glaziers replace the entire glass panel with a new piece of Grade A Toughened Safety Glass manufactured specifically for the pet door opening.
This process ensures the installation remains safe, compliant, and attractive.
If you’re considering glass, our guide What You Need to Know About Installing Your Pet Door Into Glass explains the process in detail.
You should also read Pet Door Safety Glass Replacement Explained to understand why replacing the glass panel is usually necessary.
Dog Doors in Double Glazing
Double-glazed units require an even more specialised approach.
Because double glazing forms a sealed insulated glass unit, installers cannot modify the existing panel. Instead, manufacturers must create a completely new insulated glass unit that incorporates the pet door opening.
Consequently, double-glazed installations require specialist measuring and manufacturing.
If your home features double glazing, read our guide to Installing Pet Doors Into Double Glazing before choosing a pet door.
What Is the Best Dog Door for Your Home?
Choosing the right dog door matters just as much as choosing the right installer.
For glass installations, many homeowners prefer premium options such as the Pet Doors Australia Premium Underbelly Pet Door. Manufactured in Australia from durable acrylic, it offers an exceptionally clean appearance in glass and includes features such as barrel bolt locks, optional double-glazing spacers, and secure lock covers.
When it comes to security screens and timber doors, the Hakuna Super Tough Pet Door remains one of the most versatile options available. Its weather-sealed flap, slim profile, and multiple size options make it suitable for most dog breeds.
And for larger dogs, the Hakuna Deluxe Aluminium Pet Door provides extra sizing options and a flexible flap that many timid dogs find easier to use.

Why Professional Dog Door Installation Matters
Although a dog door may look simple once installed, achieving a professional finish requires experience.
Professional installation helps prevent:
- Drafts around the frame
- Water leaks
- Incorrect sizing
- Glass damage
- Security concerns
- Poor flap operation
- Premature wear
Furthermore, professional installers understand how dogs actually use pet doors.
For instance, older dogs often benefit from lower entry heights and larger openings. If you have a senior dog, placement is extremely important.
What Affects the Cost of Dog Door Installation?
Several factors influence installation costs.
Installation Surface
Timber installations generally cost less because installers complete the work on-site.
By comparison, glass and double-glazed installations require custom-manufactured replacement panels.
Pet Door Size
Larger dogs require larger pet doors. As a result, larger openings often increase installation costs.
Pet Door Model
Premium pet doors with weather seals, security covers, and improved durability generally cost more than basic models.
Installation Complexity
Sliding doors, oversized dogs, security screens, and double-glazed units often require additional labour and planning.
However, homeowners should consider long-term value rather than focusing solely on upfront cost.
Dog Door Security: What Homeowners Should Know
One question we hear regularly is whether a dog door affects home security.
The answer depends on the product and installation quality.
For households concerned about security, we often recommend lockable pet doors or dedicated lock covers.
You can learn more in our article Why the Secure Lock Cover Is the Best Solution for Pet Door Security.
When properly installed, a quality pet door should provide convenience without compromising security.
Is a Dog Door Worth It?
For most dog owners, the answer is yes.
A dog door allows your pet to toilet when needed, enjoy outdoor access, and spend time in the fresh air without waiting for someone to open the door.
As a result, many dogs become calmer, more independent, and less anxious.
Many homeowners also tell us that a pet door becomes one of the most-used features of their home.
