Aluminium and UPVC Windows in Barnet | First for Windows, Bi-Folds and Composite Doors

North London Windows has a showroom and factory in Chingford, just a few short miles from Barnet where we install bi-folding doors and composite doors. Property owners welcome the many benefits and advantages associated with our high-end products. We’ve made our name in double glazing and we also install sash windows, bi-folding doors, composite doors and garden rooms. Today, with a huge product range behind us, our company offers a responsive service, at competitive prices, using our own glaziers and fitters.

North London Windows is a FENSA registered company.

Composite doors are the perfect replacement for UPVC or wood, particularly for homes in Barnet where the doors have sustained damage or warped because of changing outdoor temperatures and wet weather conditions. The internal core of a composite door, made from hardwood, has foam surround protection. Much like our aluminium bi-folding doors, this makes composite doors resistant to distortion. Reinforced frames make it difficult for potential intruders to gain unlawful entry; a reassuring selling point for many.

Because we specialise in window repairs and can cut glass to size for casement, bay and sash windows at our factory, customers can have their composite doors finished with either double glazing or triple glazing.

Homeowners usually opt for bi-folding doors as an alternative to traditional French or patio doors because they offer unrivalled design opportunities. Our Barnet customers love their sleek and slimline design. Perfect for managing air control during the warmer summer months, homeowners also choose bi-folding doors because they come in attractive styles and colours which tie in with most architectural themes.

Most importantly, bi-folding doors double back on themselves, concertina fashion, to save on space when in an open position. This makes them especially suitable for garden rooms being used as summerhouses.

Window Repairs | Double Glazing in Barnet

Our team specialises in all aspects of double glazing, including window repairs. We install double-glazed units in Barnet to bespoke specifications. Every installation has an insurance-backed guarantee. North London Windows welcomes window repair work on double glazing, including the rectification of misted units. Instead of having to absorb the cost of replacement windows, customers can save money by having the glass replaced instead.

North London Windows fits new locks and hinges, and repairs window surrounds in aluminium, UPVC, steel and wood.
