We install high quality cat and dog flaps across South London and nearby areas including Croydon, Bromley, Wimbledon, Clapham, Dulwich, Greenwich, Lewisham, Sutton, Streatham, Balham, Peckham, Tooting, Sydenham, Crystal Palace, Battersea, Merton, Herne Hill, Camberwell, Kingston upon Thames, Epsom, Bexley, Orpington and surrounding postcodes.
South London properties vary widely—from Victorian terraces and 1930s semis to modern flats—so we offer custom pet flap installations designed to suit different wall types, doors, and glazing systems. Our experienced installers ensure a clean, secure finish every time, with minimal disruption to your home.
Door installations are one of the most popular options for South London homeowners. We install pet flaps into wooden, uPVC, and composite doors, carefully cutting and reinforcing the structure to maintain insulation and security. From cat flaps to very large dog doors, we’ll help you choose the right model for your pet and lifestyle.
Microchip pet flaps are particularly popular in built-up South London neighbourhoods, as they prevent other animals from entering your home. We supply and install leading brands and ensure the flap is positioned at the correct height for your pet’s comfort.


Many South London homes feature patio doors or glazed garden access, making glass pet flap installation an ideal solution. We never cut existing double glazing. Instead, we arrange for a made-to-measure toughened glass unit with a precision-cut hole for the pet flap.
This method preserves thermal efficiency, safety, and appearance. Glass installations are perfect for French doors, sliding doors, and full-height glass panels, and they offer a sleek, modern finish that blends seamlessly with your home.
For homeowners who want to keep their doors intact or prefer a discreet solution, wall pet flap installation is a great option. We install pet flaps through brick, block, and cavity walls using secure tunnel systems that have been created to cope with daily use.
Wall installations are common in South London homes with side access or garden-facing walls and can be adapted for both cats and larger dogs.
