Aluminium is one of the most versatile and durable materials available for window frames. Unlike timber, it will not rot, warp or crack. Unlike standard uPVC, it allows for far narrower profiles, which means more glass area, more natural light, and a cleaner, more architectural look. Aluminium windows are a popular choice for extensions, open-plan living spaces, contemporary new builds and the renovation of industrial or Art Deco-era properties.
For homeowners across East London and Essex, aluminium windows offer a compelling combination of performance, aesthetics and longevity that justifies the investment.

Available with slimline steel-look profiles, authentic slim sightlines and a wide palette of classic and contemporary colours.
Every aluminium window we supply is manufactured to measure at our facility in Dagenham, East London. This means you are not choosing from a catalogue of standard sizes. Your windows are built precisely to fit your openings, ensuring clean lines, a draught-free seal and a finish that looks considered rather than generic.
Manufacturing in-house also gives us complete control over quality at every stage. Our team works to tight tolerances, and every window is checked before it leaves the factory. When our installers arrive, the product fits correctly first time. There are no gaps, no remedial adjustments and no delays waiting on a third-party supplier.
All windows are available with double or triple glazing, a choice of glass specification (including acoustic, solar control and obscure options), and a full range of hardware finishes to complement your interior style.
Based in Dagenham, we are ideally situated to serve homeowners and commercial clients across the wider East London and Essex region. We regularly work across Romford, Ilford, Barking, Havering, Brentwood, Chelmsford, Basildon, Southend-on-Sea and surrounding areas, as well as throughout the London boroughs of Redbridge, Waltham Forest and Newham.
Being local means our team can visit your property quickly for a survey and measurement appointment, and our in-house installation team returns to complete the fitting with the same care and attention. We do not sub-contract. Every job, from the first visit to the final clean-down, is handled by DDG Windows staff.
Whether you are upgrading the windows in a Victorian terrace in Ilford, fitting aluminium frames in a new extension in Brentwood, or replacing commercial glazing in Romford, we can help. Our team understands the local planning landscape and can advise on conservation area requirements and permitted development.
DDG Windows is a family-run business established in 1983. With over 40 years of experience in the fenestration industry, we have built our reputation on product quality, honest advice and installation that is done properly, the first time. We are not a national chain or a call centre operation. We are a local business with a genuine team, a real factory and real accountability to the customers we serve.
