Glass Doors & Windows Catflap Installation

Catflap fitting in Glass Doors and Windows

Adding a cat flap to a glass door or window is an excellent way to give your pet the freedom to come and go without leaving doors open or constantly letting them in and out. Unlike timber or uPVC doors, however, glass requires a completely different installation process. At Coastal Cat Flaps, we provide specialist cat flap fitting in glass doors and windows, ensuring a safe, precise and professional installation that preserves the strength, appearance and performance of the glazing.

Specialist Glass Cat Flap Installation

Glass cannot simply be cut once it has been toughened or double glazed. Attempting to drill or cut an existing sealed unit will almost certainly cause the glass to shatter. Instead, a brand-new glass panel or double-glazed sealed unit is manufactured with a precision-cut aperture specifically designed to accommodate your chosen cat flap.

Once the replacement glass has been produced, we remove the existing pane and install the new unit before fitting the cat flap. The result is a secure, weatherproof installation that looks neat and integrates seamlessly with your existing door or window.

Suitable for Double Glazing and Patio Doors

Cat flaps can be fitted into many different types of glazing, including:

  • Double-glazed patio doors
  • French doors
  • Full-height glazed doors
  • Fixed glass side panels
  • Conservatory doors
  • Selected double-glazed windows

Before any work begins, we assess your existing glazing to determine the correct specifications for the replacement unit. Every pane is manufactured to match the thickness, size and style of the original glass wherever possible, maintaining the appearance and insulation of your home.

Maintain Security and Energy Efficiency

Replacing the glass rather than modifying the existing unit ensures that your property’s insulation and weather resistance are maintained. A professionally manufactured sealed unit continues to provide excellent thermal performance while supporting the cat flap securely.

Modern glass units also retain the safety features required for external doors, giving you confidence that your installation complies with current glazing standards where applicable.

Compatible with Manual and Microchip Cat Flaps

Whether you prefer a traditional manual cat flap or a sophisticated microchip-operated model, we can fit a wide range of designs into replacement glass panels. Microchip cat flaps are particularly popular for glazed doors, allowing only your own pets to gain access while helping prevent visits from neighbouring cats or other unwanted animals.

If you’re unsure which cat flap is most suitable, we’ll be happy to explain the available options and recommend a solution based on your pet, your home and your budget.

A Made-to-Measure Solution

Because every glass panel is individually manufactured, no two installations are exactly the same. Measurements must be taken accurately before the replacement glass is ordered, making professional surveying an important part of the process. This ensures the finished installation fits perfectly and operates smoothly for many years to come.

Although replacing the glass means installations take longer than fitting into other materials, the end result is a clean, attractive solution that avoids compromising the original glazing.

FAQs

Can a cat flap be installed in any type of door?

Cat flaps can be professionally installed into most types of doors, including uPVC doors, composite doors, wooden doors and glazed doors. They can also be fitted into suitable wall panels and other locations where a conventional door installation isn’t practical.

The installation method will depend on the construction and material of the door. At Coastal Cat Flaps, we assess the best position and fitting method to provide a neat, secure and professional cat flap installation while minimising disruption to the existing door.

Can you install a cat flap into double glazing?

Yes. We provide professional cat flap installation into double-glazed doors and windows. However, a hole cannot simply be cut into an existing toughened double-glazed unit, as this would cause the glass to shatter.

Instead, a new toughened double-glazed sealed unit is manufactured with the correctly sized hole incorporated during production. Once ready, the existing glass unit is removed and replaced with the new panel before the cat flap is professionally fitted. This provides a safe, neat and permanent solution without compromising the integrity of the glazing.

How long does cat flap installation take?

A straightforward cat flap installation into a uPVC, composite or wooden door can usually be completed during a single visit, with the fitting itself typically taking around one to two hours, depending on the door construction and type of cat flap being installed.

Installations into double glazing require additional preparation because a replacement sealed glass unit normally needs to be measured and manufactured before fitting. We can advise on the expected timescale when providing your quotation.

Do you fit dog flaps?

Yes. As well as specialist cat flap fitting, Coastal Cat Flaps also provides professional dog flap installation for suitable doors, panels and other locations.

Dog flaps are generally larger than cat flaps, so careful consideration needs to be given to the size and construction of the door and the appropriate flap for your dog. We can advise on a suitable installation and professionally fit the dog flap to provide your pet with convenient access to your home and garden.
