Install Cat Flaps in Glass Doors | Maidenhead Glazing

Cat Flaps in glass

Maidenhead Glazing Services offers a professional cat flap installation service for French doors, back doors, patio doors, and other glazed panels across Maidenhead, Marlow, Henley, Ascot, Slough, and the wider Berkshire and Thames Valley area. Whether you want to give your feline friend the freedom to come and go, or you're a landlord looking to add a pet flap for tenants, our experienced glaziers can cut a clean, accurate opening and fit a brand new pane of glass complete with a pre-cut hole to suit your chosen cat flap.

Because modern double-glazed units and single safety panes are almost always made from toughened or laminated safety glass, it is not possible to cut a hole into the existing pane once it has been manufactured. Attempting to drill or cut toughened glass will cause it to shatter. That's why we replace the existing glass with a new, purpose-made pane that is toughened to British safety standards and supplied complete with the correct sized opening for your cat flap — so the whole installation is safe, guaranteed, and building-regulations compliant.

We work with all the popular cat flap and pet door brands, including SureFlap, Sure Petcare microchip cat flaps, Cat Mate, PetSafe, and Staywell, and we can accommodate most standard and large sizes. If you have a microchip-enabled cat flap that requires a specific cut-out, simply let us know the make and model when you call and we'll ensure the new glass is manufactured to the exact specification. We also install dog flaps and small pet doors in glass panels on request.

Our mobile glazing service means we come to you, measure up on site, and order the new toughened glass to fit your door frame precisely. Once the new pane is ready, we return to fit the glass and install your cat flap, leaving everything clean, secure, and ready for your pet to use. The whole process is typically completed across two short visits, and because we only replace the glass, it is far more affordable than replacing the whole door.

Cat Flap Installation in Maidenhead

We install a range of cat flap types to suit different homes and pets. Glass pane cat flaps are our most common request — a new toughened pane is manufactured with a pre-cut opening to suit your chosen flap, then fitted into your existing door frame. For doors where the glass isn't being replaced, we can also fit door-mounted cat flaps into uPVC panels and composite door skins, cutting a clean, accurate opening on site. Microchip cat flaps, which read your pet's implanted chip to allow access only to your cat, are increasingly popular and we're fully set up to accommodate the specific cut-out dimensions each model requires.

The glass cutting process for cat flap installation is more involved than it sounds. Because modern double-glazed units and single safety panes are almost always toughened or laminated, the existing glass cannot be drilled or cut after manufacture — attempting to do so will shatter the pane. Instead, we measure the opening, order a brand new pane of toughened safety glass manufactured complete with the correct sized hole for your cat flap, and fit it in place of the old pane. The result is a safe, guaranteed, and building-regulations compliant installation.

Cat flap installation in Maidenhead is compatible with a wide range of door types, including uPVC French doors, aluminium sliding and bi-fold doors, composite back doors, and timber panels. We work with all the leading brands — SureFlap, Sure Petcare, Cat Mate, PetSafe, and Staywell — and can accommodate most standard and large sizes. If you're unsure whether your door is suitable, simply tell us the make and model when you call and we'll confirm the best approach for your setup.
