Patio Doors London, Get A Quote

London Window Company supplies and fits patio doors for homeowners across London and the surrounding areas. From sliding doors in a compact terrace to large bi-fold panels opening onto a suburban garden, we cover a wide range of styles, materials, and sizes to suit what your home actually needs.

Every installation is carried out by our own fitting team. No subcontracting, no strangers turning up unannounced. Just a straightforward job done properly from start to finish.

What types of patio doors do you offer?

There are three main styles we fit regularly across London. Sliding patio doors are the most popular choice for smaller spaces, since the panels glide along a track rather than swinging open into the room. You can choose from two, three, or four panel layouts depending on the width of your opening, and they work particularly well in kitchens and living rooms that back onto a garden.

French doors open outward as a pair and suit homes where a traditional look matters. They create a wide, unobstructed opening and can include a low-level threshold, which makes them practical for anyone with mobility considerations. Bi-fold doors fold back on themselves in a concertina action and can span up to six metres, covering almost the full width of a wall when fully open. They come in two to seven panel configurations and are available in both uPVC and aluminium.

What materials are available, and does it make a difference?

Both uPVC and aluminium are solid choices, and the right one depends on your priorities. uPVC is a proven, low-maintenance material that performs well thermally and costs less than aluminium. It comes in a good range of colours including white, anthracite grey, black, and woodgrain foil finishes.

Aluminium frames are thinner, which means more glass area and a cleaner, more contemporary look. The slimline profile suits modern extensions and open-plan layouts particularly well. Both materials are powder-coated or finished to last, so there is no painting required and cleaning is straightforward.

How energy efficient are your patio doors?

All the patio doors we supply carry an A+ energy rating as standard. The sealed double glazed units are filled with argon gas, which improves thermal insulation compared to air-filled units. Warm edge spacer bars run around the perimeter of the glass unit, reducing cold bridging at the edges where heat loss is most likely to occur.

This matters in London homes because heating bills are a real concern, especially in older properties that already lose heat through the walls and roof. Upgrading to well-fitted, thermally efficient patio doors can make a noticeable difference to how warm a room feels through autumn and winter.

How secure are patio doors?

Security is built in as standard rather than offered as an optional extra. Every patio door we fit includes the following:

• Multi-point locking along the full height of the door, not just a single central lock point
• Anti-lift devices on sliding doors to prevent the panels being lifted out of the track from outside
• Toughened safety glass throughout, which is significantly harder to break than standard float glass
• Shootbolt locking at the top and bottom of French and bi-fold doors for added strength at vulnerable points
• Internally glazed units so the glass cannot be removed from outside the property

If you have specific concerns about security, particularly for a ground floor installation or a rear access point, just mention it when you call. We can discuss the options that make most sense for your property.

How long does fitting take?

Most patio door installations are completed in a single day. Bi-fold doors across a wider opening may take a day and a half, but in most cases your home is fully secured again before our team leaves in the evening.

Before the fitting date, one of our surveyors will visit to measure the opening accurately and confirm the specification. This means the doors are made to the exact size of your opening, which avoids delays on the day. From survey to installation, the typical lead time is a few weeks depending on the style and specification you choose.

What guarantee do I get?

Every patio door we supply and fit comes with a full ten-year guarantee. This covers the frames, the double glazed sealed units, and the hardware including locks and hinges. If something fails within that period, we will come back and sort it. No lengthy phone queues, no arguing over liability.

The guarantee is transferable if you sell your home, which is worth noting if you are thinking about the long-term value of the work.
