Why Install a Dog Door?

A dog door is more than a convenience — it gives your pup the freedom to head outside for a toilet break, play, or a bit of sunbathing, without needing to bark for attention. It also gives you peace of mind during long days or busy routines.

Modern dog flap installations are designed with durability and insulation in mind, helping you maintain energy efficiency and home security while keeping your pet happy.

Whether you have a small breed or a big adventurer, we can install a dog door that suits their size and habits.

What to Consider Before Installing a Dog Door

Every home and pet is different. Here are a few things to think about before you book your dog door installation:

Glass type and door configuration: Some setups—especially double-glazed units—may require special treatment or replacement glass.
Your dog’s size and breed: Choosing the right door size ensures your dog can use it comfortably and safely.
Locking and security: Many dog doors now include locking options to help you control when and how they’re used—perfect for night-time or when you’re away.

We work with a wide range of dog doors, including:

Standard flap doors for small to large breeds
Heavy-duty, weather-resistant dog flaps
Lockable dog doors for added security
