We work with homeowners, developers and commercial clients across East London, offering a full range of glazing solutions – from sleek aluminium frames to low-maintenance UPVC systems. Our Dagenham manufacturing base sits right at the heart of East London, meaning fast turnaround, short lead times and a team that has spent decades working across the area’s diverse mix of properties.
Replacing your windows is one of the most impactful upgrades you can make to a home. Improve thermal efficiency, reduce noise and refresh the look of your property from the outside in.
East London’s housing stock is one of the most varied in the country – Victorian and Edwardian terraces in Walthamstow and Leyton, post-war estates in Barking and Dagenham, Georgian and period properties in Bow and Bethnal Green, and a wave of new build developments across Stratford, Canary Wharf and the Olympic Park corridor.
That variety means there’s no single right answer when it comes to glazing, and it’s exactly the range our team has spent over 40 years navigating.
Slim profiles, excellent strength and a broad choice of RAL colours. Aluminium windows are the go-to for homeowners who want a premium finish that lasts. Available in casement, bay, picture, tilt & turn, shaped, and gable frames.
From the Victorian terraces of Walthamstow to the modern developments around Stratford and Canary Wharf, our aluminium windows deliver the same premium finish and exacting standard regardless of property type – and from our Dagenham site, we’re never far from the job.
A practical, cost-effective choice that doesn’t compromise on performance. Available in a wide range of styles, colours and finishes – from square and rectangular to arched and circular frames – with each and every window can be tailored to your exact measurements.
Across East London’s large and varied residential stock – from Barking’s post-war semis to the converted terraces of Leyton and Forest Gate – uPVC remains the most practical and popular choice for straightforward replacement projects. Our flush casement options work particularly well on the Victorian and Edwardian properties common across the area.
Our heritage windows capture the look of traditional steel designs using modern materials by delivering the same timeless aesthetic with far better thermal performance and security.
East London has a number of active conservation areas – in Walthamstow Village, parts of Bow, Bethnal Green and Wanstead – where our heritage range is the appropriate and often required solution. The steel-look profiles preserve the character planners expect while delivering the thermal performance homeowners need.

All our windows & doors are built in our Dagenham manufacturing site
Doors take more wear than almost anything else in a home, and across East London’s varied housing stock the right choice varies considerably. We supply and fit the full range across the area – from heritage-influenced composite front doors on period terraces in Walthamstow, to aluminium bi-folds for extended properties in Stratford and Leyton. Our team will guide you to the right product for your home and street.
Whether you’re upgrading an original entrance or replacing something that’s simply past its best, our team will help you get it right.
High-performance, built to last, and exceptional security. Available in a wide range of RAL colours and configurations – from bi-folds to front entrance doors – and made to order for a precise fit.
Rear kitchen extensions are widespread across East London’s Victorian and Edwardian terraces, and aluminium bi-fold and sliding doors are consistently the most popular choice for opening these spaces to the garden. Everything is made to measure at our Dagenham site, which is never far from the job.
A reliable, low-maintenance option that performs well on both security and insulation. Available in a range of styles, finishes, and colours to suit all property types.
A practical and popular choice right across East London’s large and varied housing stock – from terraced rentals in Leyton and Manor Park to owner-occupied semis in Barking and Dagenham. Reliable, low maintenance and well priced, with competitive lead times from our nearby Dagenham manufacturing site.
Our GRP composite doors offer the look of a solid timber door without the warping, swelling or repainting that comes with real wood. The outer skin is moulded from glass reinforced plastic, giving it exceptional durability and a finish that holds its colour and texture year after year.
Consistently popular across East London’s Victorian and Edwardian terraces for front door replacements, where the composite range in heritage colours works naturally with the original London stock brick and tiled entrance paths common across E10, E11, E17 and the surrounding postcodes.
A roof lantern is one of the most effective ways to flood a kitchen extension or garden room with natural light. DDG Windows supplies and installs aluminium roof lanterns across East London, available in a variety of sizes and glazing options to suit your project and budget.
Our roof lanterns are thermally broken as standard, keeping heat in during winter and reducing solar glare in summer - meaning your new space is comfortable year-round.
Our team regularly carries out installations across East London, covering Stratford, Hackney, Bow, Bethnal Green, Stepney, Poplar, Canary Wharf, Docklands, Walthamstow, Leyton, Leytonstone, Forest Gate, Manor Park, Ilford, Barking, Dagenham, Romford, Chadwell Heath, Hornchurch and the surrounding areas.

DDG Windows has been based in Dagenham since 1983 – right at the eastern edge of the capital – and East London is the area we know better than anywhere.
Some areas have active conservation designations and Article 4 restrictions that affect glazing choices, while others are straightforward permitted development. Our team knows which is which, and we’ll always check what applies to your specific property before recommending a product.
Whether your home is a period terrace in a conservation area or a modern flat in a new development, the advice we give will be based on genuine local knowledge rather than a generic product pitch.

Usually within 48 hours of your enquiry or site visit. Our Dagenham manufacturing base sits right in the heart of East London, so we can arrange surveys quickly across the area and turn quotations around without delay.
It depends on the scope of the job and site conditions, but as a general guide our two-man installation teams typically fit three to six windows per day. We'll give you a clearer timeline once we've completed your site survey - for larger East London properties with multiple replacement windows or doors, we'll factor that into the schedule upfront.
We'll confirm your style choices, glass spec, opening configurations and colour options, then put everything into a formal order. A deposit is required and a site survey will be booked so we can take accurate measurements before manufacturing begins at our Dagenham facility.

East London has several active conservation areas - including Walthamstow Village, parts of Bow and Bethnal Green - where planning restrictions can limit what replacement glazing is permissible. In practice this usually means like-for-like replacements in appropriate materials, which often points to our heritage window range. We'll check what applies to your specific address during the initial consultation and advise accordingly.
