Cat Flap Fitter.

Our mission is solving the problem of allowing your cat or dog access to the outside world. Having a cat meowing to be let out  is frustrating. We will be fast, friendly and professional to solve this problem and get your pet access to the outside world.

Offering a bespoke service, the glass is made to measure and the cat flap is fitted as part of our service.

Not sure which cat flap or pet door you need? We stock a range of cat flap and dog door options and are happy to advice the best option for you and your pet.

If you are looking for a more cost effective option for a half glass upvc door then your glass can be replaced with a upvc panel and the cat flap fitted that way instead.

Furthermore, we can advise you on the best method of installing your cat flap or pet door, because sometimes all options are not obvious at first glance. Installation can be into a window or a door, be it double glazing, upvc panel or a wood/timber panel.

Most of all, we know that you are keen to get your pet it’s freedom and so we will work quickly to turn around your order.

The typical lead times for a cat flap installation is 5 to 7 working days from when obtaining the exact measurements of your glass. This is the length of time it takes the glass manufacturer to produce the new double glazed unit.

Free Cat Flap Fitting Estimates

For all cat flap installation into glass and double glazed units, we will need to measure the exact width, height & cavity of glass. We are more than happy to survey free of charge.

Customers are advised that its best to get us to survey ten days before you are ready to commit.

Installation into existing double glazing units? ​

Double glazing cannot be modified as the glass is toughened, air tight and made to measure. A brand new unit will be required.

After survey a new double glazed unit for your cat flap is then made by a double glazing manufacturer.

They will cut out a hole for the cat flap in both pieces of glass before they go to be toughened and made into a double glazed sealed unit.
