Choice of materials

Our window frames are manufactured in our Dagenham site for clients in Greater London, meaning that you can easily choose whether you would like your window replacement to be in aluminium or UPVC.

Energy efficient window replacement

Our double glazed windows are ideal for keeping in heat, meaning that your new windows can actually help your home become more energy efficient. They are a secure, sound-reducing option, cutting down on street noise.

Types of glass available

There are multiple glass options for your new windows. K-Glass combats heat loss, making the double glazing as effective as triple glazing. If your window is below 800mm, or you would simply like the security of a stronger glass, choose toughened glass. Decorative textured glass is the best option when privacy is needed, but is also a stylish way to let light into internal rooms.

Affordable and reliable new window installation

We are Fensa registered, meaning that your new window installation will be carried out to high standards. You can be certain of receiving friendly, efficient service and a quality result with DDG Windows.
