Fitting into timber and composite doors
Timber doors are the simplest home for a cat flap: the opening is marked out, cut cleanly and the flap screwed in place with a neat finish on both faces. Composite doors can usually take a flap too, though the cutting needs more care to keep the skin and core intact and the finish tidy.
Panelled doors need a moment of thought about which panel the flap sits in, since cutting through a moulding or a joint weakens the door and looks wrong. We mark out the position with you before any cutting starts.
The flap is positioned at the right height for your cat and clear of any panels, locks or glazing bars in the door.
Glass doors and windows need a glazier
If you want a cat flap in a glass door or window, that is a job for a glazier rather than a carpenter, since glass and sealed double-glazed units cannot simply be cut on site. A glazier can supply a new unit with the opening made in the factory, and we are happy to say so honestly rather than attempt something outside our trade.
Once the new glazed unit is in, we can fit the flap itself and make good any surrounding timberwork, so the job still finishes with us even if the glass part goes elsewhere.
Cat flaps through walls
Where a door is not an option, a cat flap can go through an external wall with a tunnel liner. It is a bigger job than a door fitting, since the wall has to be cored and made good inside and out, but it suits utility rooms and kitchens where the door position does not work.

Choosing the flap
Basic four-way locking flaps suit most homes, while microchip flaps only open for your own cat, which keeps neighbouring cats and wildlife out. We fit flaps you have bought or advise on a suitable model for the door and your cat.
If the door itself needs attention at the same time, such as easing or adjustment, our door trimming and internal doors pages cover that work.
Booking an installation
Have the flap on site or ask us to supply one. Request a free quote or call 07735 852901.
Most door installations are finished in a single short visit, and the flap is tested with the door opening and closing properly before we leave, so your cat can start learning it straight away.
