Cat Flap Fitting in North London

Montrose Glass provides cat flap fitting in North London and is available 24 hours a day, 7 days a week, 365 days a year. Whether you need a cat flap fitted into glass, a uPVC door, a timber door, or a wall, our glaziers carry out the work on site with no call-out fee.

North London covers a wide spread of housing stock, from the Victorian terraces of Islington and Holloway to the Edwardian semis of Muswell Hill and the newer builds around Wembley and Barnet. Many of these properties have original timber frames, older single-glazed windows, or more recent double glazing, each requiring a slightly different approach to pet door installation. Our glaziers are familiar with all of these property types and carry glass that can be cut and prepared on site, meaning many cat flap installations in North London are completed in a single visit.

What Does Cat Flap Installation in North London Involve?

Cat flap fitting in North London covers several different installation types depending on where the flap is going. In a single-glazed window or door panel, the glazier cuts a hole in the existing pane and fits the pet door directly. In a uPVC or timber door with a solid panel, the hole is cut into the panel itself. When fitting a cat flap into a wall, the job involves cutting through the masonry and fitting a tunnel to bridge the wall thickness. Each of these options is straightforward for a qualified glazier and can usually be completed on the day.

Fitting a cat flap in glass into a double glazed unit requires a different process. A sealed unit cannot simply be drilled or cut on site because doing so would break the airtight seal between the panes and cause the unit to mist. Instead, Montrose Glass supplies a new toughened glass sealed unit with the cat flap hole pre-cut and the flap already fitted, then installs it into your existing frame. Our vans are stocked with glass that can be cut and prepared, and many jobs are completed on site without a second visit. We offer a range of flap types including microchip cat flaps, locking cat flaps, and standard four-way locking options, so you can choose the level of security and access control that suits your household.

Why Does Professional Cat Flap Fitting Matter in North London?

Cutting into an existing sealed double glazed unit without replacing it breaks the seal between the two panes. Once the seal is gone, warm air carrying moisture gets in and the unit mists from the inside, which cannot be cleaned and means the unit needs replacing anyway. Beyond the misting, a poorly fitted cat flap in double glazing creates a gap that allows draughts and rainwater into the frame, causing damage to the surrounding structure over time. In a conservation area, such as parts of Highgate or Crouch End where planning conditions can apply to alterations, it also matters that any work is carried out neatly and to a standard that does not affect the appearance of the window.

Professional cat flap installation in North London by a qualified glazier removes these risks. When a new double glazed cat flap unit is supplied and fitted correctly, the window remains fully weatherproof, the thermal performance is maintained, and the frame is not compromised. The same applies to a Double Glazing replacement more generally: the quality of the installation determines how long the unit performs. Using an experienced cat flap glazier in North London means the job is done once, to a standard that protects your home and satisfies your insurer.

Montrose Glass have experience in installing cat flaps for windows in Glaziers in North London 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.
