We also offer additional services such as replacing half doors with UPVC, cutting through timber doors and panels, or upgrading your existing cat flap to a newer model.
Can you cut into my existing glass?
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.
Microchip vs. Classic Cat Flap ?
Conventional cat flaps lack selective access, leaving your home vulnerable to unwanted visitors like foxes and stray cats. One of the most common issues is other cats entering your home and causing problems, such as spraying. In contrast, microchip cat flaps offer a secure solution. These flaps use a scanner to read your pet’s microchip, allowing only programmed cats to enter and exit. This provides reassurance to owners that only their pets can access the home, ensuring a safe and secure environment for both you and your cat. Read our full guide on choosing the right cat flap

Measuring Your Glass

Cat Flap Installation Costs
Fitting cat flaps into small windows is more cost-effective, as double glazing is charged per square meter; the smaller the glass, the lower the price.
Glass Production Lead Times
We advise customers that it is best to book a survey ten days before you are ready to proceed, to allow time for glass manufacturing.
