Installing a cat flap requires the correct approach depending on the type of door or panel involved.
For double-glazed and toughened glass doors, a replacement glass unit must be manufactured with a precision-cut opening before installation. For UPVC infill panels and timber doors, a cat flap can often be installed directly into the existing panel or door, providing a cost-effective and efficient solution.
Our experienced team will assess your existing door and recommend the most suitable installation method to ensure a secure, weatherproof, and professional finish.
