Window Repairs in the North London Area

Much of the work we do in the North London area focuses solely on window repairs. Some property owners make the expensive mistake of replacing their existing windows when window repairs would just as easily have helped. North London Windows replaces broken glass, repairs damaged frames and replaces broken locking mechanisms. We can undertake window repairs on installations with aluminium, uPVC or wooden frames.

We dispatch our glaziers to complete work on your property and we never use external contractors to perform window repairs on our behalf. You only deal with our company and nobody else – and that’s a promise! Save money today by enquiring about window repairs over the phone. We’ll be happy to advise you.

Our team can also repair windows for garden rooms and outbuildings.

Double Glazing for North London Homeowners

National double glazing companies advertised in the media have, in the past, done little to help our industry. Their high-pressure approach to sales, and their expensive pricing, have left behind a trail of dissatisfied customers. At North London Windows, we undertake double glazing installations at fair, competitive prices without the unwelcome sales pitch.

We install sealed double glazing with a high energy rating. Double glazing plays an important part in retaining heat and lowering utility costs. It also boosts property kerb appeal and adds welcome resale value to your North London home. Only the best products, with the highest ‘U’ and ‘R’ values, are good enough for our customers.

North London Windows can fit double glazing in casement, bow, tilt-and-turn and sash windows, and in French, patio and bi-folding doors. Composite doors also come with your preferred choice of glass. We can even use double glazing when performing window repairs or building garden rooms.

Bi-Folding Doors and Patio Doors

The slim profiles of bi-folding doors make them less obtrusive than traditional patio doors. For property owners in North London who are looking to achieve a sleeker and more modern finish, our aluminium bi-fold doors achieve the desired look without compromising strength or visibility. Bi-folding doors have amazing versatility for those trying to find the perfect blend between interior décor and exterior landscaping themes.

North London Windows can undertake installations in all surrounding parts of our main trading area, including Barnet, Enfield, Islington and Tottenham. We also specialise in patio doors, helping our North London customers to combine indoor and outdoor space with tailored installations that integrate perfectly with a property’s current architecture.

North London’s Leading Choice for Composite Doors

Flexible design options and exceptional durability are key factors that make composite doors so popular with property owners in the North London area. We can supply and install high-end composite doors with uPVC, thermoplastic, wood or aluminium skins, complete with hardwood cores and colour impregnated skins that blend in seamlessly with double glazing and other design elements around your property.

Composite doors never warp, provide exceptional security and have minimal maintenance requirements. Proven to be the most energy-efficient doors available in today’s modern and environmentally aware marketplace, our range of composite doors also gives our valued North London customers an extensive range of colour and styling options.

And with garden rooms available too, just a single call does it all.
