How we work

When it comes to installing cat flaps for glass, we use a very special process that ensures high-quality results every time. There are four steps involved in that process that span from the initial on-site assessment to the first time your feline walks through its new pet flap. The four steps include:

Get in touch

There’s no need to wait for an in-person consultation. You can get an online recommendation from one of our experts with some simple measurements and photos. From your answers and submissions, we’ll provide a list of our top recommendations for the best cat flap or dog door for your pet.

Initial Site Visit & Evaluation

A specialist will visit your home, inspect your glass door, and take measurements. This helps us in the manufacturing of the replacement panel of glass. At this point, we can also give you a quote.


Manufacturing New Glass Panel

We will make a panel of glass that perfectly fits your door’s specifications, including where the cat flap will go. Then, we temper the glass making it four to five times more durable than untempered glass. This tempering process is performed twice on double-glazed glass.


Replace Your Door’s Glass

We return to your home, remove your existing glass panel, and replace it with a new one. This new glass will fit your door just like new, except it will have a hole placed perfectly for your pet flap.


Fit the Cat Flap

With the new panel of glass placed, we can install the cat flap into the door and let your cat come and go anytime.
