Cat Flaps In Addington

Attempting to cut into an existing sealed double glazed unit yourself, or using a fitter who is not experienced with glass, will almost certainly break the seal between the two panes. Once that seal fails, moisture enters the unit and causes the familiar cloudy misting effect that cannot be cleaned away. A broken sealed unit also loses its thermal insulation, increasing heat loss and energy costs. In a double glazed cat flap installation in Addington, the only correct solution is to replace the sealed unit entirely with a new toughened glass unit that has the cat flap aperture already fitted.

An ill-fitting cat flap also creates practical problems beyond the aesthetics. Draughts, rainwater ingress, and gaps around the frame are common results of flaps that have not been sized or seated correctly. In the wetter autumn and winter months that affect south London, even a small gap around a poorly fitted pet door can cause damp issues over time. Professional fitting ensures the flap is sealed, level, and properly secured. For related work such as replacing a damaged or misted pane while a cat flap is being installed, our Double Glazing service covers the Addington area in full.

Toughened glass is the standard for double glazed units, and any replacement pane used in a cat flap installation should meet the same specification as the original unit. Montrose Glass uses toughened glass as standard for sealed unit replacements, keeping your windows compliant with current building regulations and safe for your household.
