Installation into existing double glazing units? ​

Alterations to double glazing are unviable due to the tempered and airtight glass, which is precisely cut. A new unit is the indispensable remedy.

Following the survey, a proficient double glazing manufacturer crafts a new double-glazed unit tailored precisely for your cat flap.

They will intricately cut out a hole for the cat flap in both glass pieces before they proceed to the toughening process and the creation of a double-glazed sealed unit.

Microchip V Classic Cat Flap ? ​

The traditional cat flap doesn’t offer selective access, which can make your home open to the entry of other creatures like foxes that may intrude and disturb your cat. A widespread challenge is the entry of other cats that can lead to territorial spraying and marking of your space. Featuring a scanner, the microchip cat flap reads your pet’s microchip and allows entry exclusively for cats that have been designated 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 most common location for fitting a cat flap, typically either as 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 is desirable as the cost of double glazing is calculated per square meter, the smaller the pane of glass the cheaper the job.

Lead Times

We recommend that customers schedule a survey with us at least ten days prior to their commitment.
