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.

The result is a sharp, minimal aesthetic that suits both new-build properties and renovations where simplicity is key. Thermally broken as standard, AluK flush windows achieve excellent U-values and meet or exceed current Building Regulations requirements for energy efficiency.

Heritage Aluminium Windows
Our heritage aluminium windows are designed to capture the character of traditional steel-framed windows from the Art Deco and Crittal eras, whilst delivering the thermal performance, security and low-maintenance benefits of modern aluminium. They are an ideal solution for period properties, industrial conversions, conservation area homes and any project where the proportions of a traditional window are required but modern standards must be met. Available with slimline steel-look profiles, authentic slim sightlines and a wide palette of classic and contemporary colours.
Every aluminium window we supply is made to measure at our Dagenham factory in East London. Rather than choosing from standard sizes, your windows are built precisely to fit your openings, giving clean lines, a draught-free seal and a considered finish.
Manufacturing in-house gives us complete control over quality. We work to tight tolerances and check every window before it leaves the factory, so it fits correctly first time, with no gaps, adjustments or supplier delays.
All windows are available with double or triple glazing, a choice of glass (including acoustic, solar control and obscure), and a full range of hardware finishes to suit your interior.
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.
Aluminium windows are generally priced higher than standard uPVC, reflecting the material cost, the precision engineering involved and the longer expected service life. However, the gap is smaller than many people expect, and when you factor in the lifespan of an aluminium window (40 to 60 years compared with 20 to 35 years for uPVC), the long-term cost can be comparable or lower. For homeowners seeking a premium finish, enhanced thermal performance and a product that will not need replacing for decades, aluminium frequently represents better value.
Modern aluminium windows incorporate thermally broken profiles, where a polyamide strip separates the inner and outer aluminium sections to dramatically reduce heat transfer through the frame. Combined with double or triple glazing, today's aluminium windows achieve U-values that meet or exceed the requirements of current Building Regulations (Part L). All of the aluminium windows we supply at DDG are thermally broken as standard.
With proper installation and minimal maintenance, aluminium windows can last between 40 and 60 years. Aluminium does not rot, warp, swell or corrode under normal environmental conditions. The powder-coated finish is durable and resistant to fading, chipping and UV degradation. Occasional cleaning with a damp cloth and mild detergent is all that is typically required to keep them looking good throughout their service life.
Yes. Aluminium windows can be powder-coated in virtually any colour from the RAL range, which comprises over 200 standard shades. Popular choices include anthracite grey (RAL 7016), black (RAL 9005), white (RAL 9010) and bronze, but we can accommodate any colour preference. We also offer dual-colour finishes, allowing you to choose different colours for the interior and exterior faces of the frame.
In most cases, replacing like-for-like windows in a standard residential property falls under permitted development and does not require planning permission. However, if your property is in a conservation area, is a listed building, or if you are changing the style, material or arrangement of windows significantly, permitted development rights may not apply. Our team can advise on this during your free survey. We work regularly across East London and Essex, including areas with conservation area designations.
The installation time depends on the number of windows being fitted and the complexity of the job. A typical residential installation of five to ten windows will usually be completed in one to two days. Our team arrives with all windows pre-measured and manufactured, so the process on site is efficient and minimally disruptive. We leave your home clean and tidy at the end of each day.
Yes. In addition to working with homeowners, DDG Windows supplies aluminium windows to builders, developers, contractors and architects across East London and Essex. Our in-house manufacturing capability means we can produce bespoke products to specification, within competitive lead times.
