Installation into existing double glazing units? ​

Double glazing retains its unalterable state due to the toughened, airtight glass that’s made to measure. A fresh unit will be the essential remedy.

Following the survey, a seasoned double glazing manufacturer skillfully produces a new double-glazed unit customized to fit your cat flap.

Before being toughened and turned into a double-glazed sealed unit, they will meticulously cut a hole for the cat flap in both glass pieces.

Microchip V Classic Cat Flap ? ​

The standard cat flap doesn’t ensure selective access, leaving your home potentially open to other creatures such as foxes that might enter and create disturbances for your cat. One of the most prevalent issues is the entry of other cats that can lead to spraying and marking your space. The microchip cat flap features a scanner that reads your pet’s microchip, allowing access exclusively to cats that have been designated for that specific cat flap. This assures owners that only their pet has the privilege to enter and exit the home.

We Fit Cat Flaps Into


Opting for the back door is the usual preference for cat flap placement, typically involving a full-length or half-length double-glazed unit or a UPVC panel.


Mostly we fit cat flaps into double glazed french doors and Patio doors,


We are professional glaziers and fit over twenty cat flaps into glass & double glazing each a week; we will always give you our honest opinion.


For all cat flap installation into glass and double glazed units, we will need to measure the exact width, height & cavity of glass. 


Fitting Cat Flaps into small windows is desirable as the cost of double glazing is charged per square meter, the smaller the pane of glass the cheaper the job.
