Installation into existing double glazing units? ​

Double glazing remains unalterable, as the glass is toughened, airtight, and precisely tailored. A completely new unit will be necessary.

After the survey, a skilled double glazing manufacturer intricately fabricates a new double-glazed unit customized to accommodate 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 provide selective access, making your home vulnerable to other creatures such as foxes that could enter and bother your cat. An often observed problem is the entry of other cats into your space, leading to territorial spraying and marking. Equipped with a scanner, the microchip cat flap reads your pet’s microchip and allows entry solely for cats that have been authorized for that specific cat flap. This gives owners the peace of mind that only their pet is granted access to enter and exit the home.

We Fit Cat Flaps Into


The back door is the go-to location for cat flap installation, often featuring either a full-length or half-length double-glazed unit or a UPVC panel.


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


We are experienced 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 offers benefits as the cost of double glazing is calculated per square meter, the smaller the pane of glass the cheaper the job.
