Door Pet Flap Installation in South London

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.

Glass Pet Flap Installation – South London Specialists

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.

Wall Pet Flap Installation in South London

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.

Can you fit a cat flap into my existing double glazing?

We don’t cut existing sealed units. For glass installations, we replace the pane with a new made-to-measure sealed unit manufactured with the correct hole.

How long does it take?

Door installs are often around 2 weeks (availability dependent). Glass installs typically involve survey/confirmation plus manufacture, often around 3–4 weeks in total.
