What Does Cat Flap Installation in Merton Involve?

Cat flap fitting in Merton covers a range of installation types depending on where you want the flap positioned. The most common locations are a uPVC or timber door panel, a single glazed window or side panel, a sealed double glazed unit, or an external wall. Each surface requires a different approach, and a qualified cat flap glazier in Merton will assess the most suitable option when they arrive at your property.

When the installation involves glass, whether that is a single pane or a double glazed cat flap in an insulated sealed unit, a new pane is cut and prepared with a pre-formed hole sized to the flap. This means the existing sealed unit is never drilled or cut on site in a way that compromises its integrity. The new unit is then fitted into your existing frame, keeping the installation weatherproof from the outset. You can also choose from a range of flap types, including microchip cat flaps that only open for your pet, locking cat flaps that can be secured at night, and standard magnetic flaps. Our glaziers will advise you on the right product for your home and your cat during the on-site visit, at no call-out charge.

Many of the Victorian and Edwardian terraces in areas such as Wimbledon Chase and South Merton have timber-framed doors with original or replacement glass panels alongside them. These side panels are a popular location for cat flap in glass installations, and our glaziers are experienced in working with both period timber frames and modern uPVC equivalents found across newer Merton developments.

Why Does Professional Cat Flap Fitting Matter in Merton?

Attempting to cut into an existing sealed double glazed unit will break the hermetic seal between the panes. Once the seal fails, warm air carrying moisture enters the cavity and condenses on the inner surfaces of the glass, causing the permanent misting that cannot be cleaned away. A misted unit needs full replacement, so a DIY attempt at cat flap in double glazing in Merton can easily create a more expensive problem than the one you started with. Professional pet door installation in Merton avoids this entirely because a glazier supplies a correctly manufactured replacement unit with the cat flap already fitted before it arrives at your home.

An ill-fitting flap is a separate but equally practical concern. A pet door that is poorly aligned or incorrectly sized for the aperture will allow draughts, rainwater, and even insects into your home. For Double Glazing installations in particular, the new toughened glass unit supplied by Montrose Glass is manufactured to the precise dimensions of your frame, so the finished installation is secure, insulated, and built to last. Professional glass cutting also ensures the edges of the aperture are clean and safe, which matters both for the integrity of the pane and for the safety of your pet passing through it regularly.

Montrose Glass have experience in installing cat flaps for windows in Merton to give your pet a custom entrance to your home where needed.

We used Montrose Glass for a construction project in London recently. They were fantastic. Service was great, as was the workmanship. The 2 glaziers are a credit to the company. Also, they turned up and carried out the works during heavy snowfall without complaint. We would definitely recommend them.

I needed to get some work done for quite a while on my house, but kept putting it off - after a couple of calls to Montrose Glass I felt comfortable discussing it and they made it so easy and simple that I\'ve decided to get it all sorted. Great service and I have already got them quoting my mums house and will have no worries referring them on in the future.
