Peace of Mind for You and Your Pet

At Pet Flaps UK, we have taken our love and care for pets to new heights. We know that it’s important for your pet to be able to get in and out safely and without taxing their bodies, and we know it’s important for you to have peace of mind knowing that your pet and your home are safe at all times. That’s why we offer cat flaps and dog doors for composite doors. Composite doors are safe and secure, but they are also complex if you want to install a pet door. Our team is trained to work with composite doors of all kinds. We can install a pet door into your composite door without compromising the safety and security of your door. When you work with inexperienced installers to put a pet flap in your composite door, you risk damaging both the door and the flap.  Give our professional team a call instead!

Why should you Hire Professionals for your Pet Door Installation?

A lot of people don’t think about the types of doors they have when they decide to install a flap for their pets. Then, when they call an installer, the installer refuses to do the work because it turns out they have a composite door. Installing a pet door for composite doors isn’t exactly a walk in the park. These types of doors are more complex than uPVC, and of course, more complex than plain wooden doors. Take a look at a few reasons why it’s important to make sure you hire professionals for your pet door installation:

Special Locking Mechanisms

 Many composite doors have unique locking systems for added security. Your composite door could be set up with a Yale locking cylinder or multiple locking systems. These systems have to be carefully assessed and nimbly avoided in the pet door installation process. If the installers don’t know what they’re doing, they could damage the locks and compromise your home’s security.

Voided Warranties

 Did you know that you could void the warranty of your composite door if you have a pet door installed? That’s why we have partnered with Rockdoors to learn the intricacies of their doors so we can install pet flaps without voiding the warranty. All you have to do is give us the serial number of your door, schedule an installation time, and we will contact Rockdoor so they can update your warranty.

Ease of Installation

 Many pet door installation companies have a very hard time installing flaps into composite doors, which means the job may take longer than it should. You may even be charged more due to the installer’s lack of experience with composite doors. When you work with a professional company like Pet Flaps UK, you can rest assured that the job will get done in a timely and safe manner.
