We work with homeowners, developers and commercial clients across Upminster, offering a full range of glazing solutions – from sleek aluminium frames to low-maintenance UPVC systems. Our Dagenham manufacturing site is just a short drive away, making us one of the most local glazing specialists serving the area.
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.
Upminster sits at the outermost edge of the Elizabeth line and has a distinctly different character to inner East London – larger plots, more detached homes, a quieter suburban feel, and a housing mix that ranges from solid interwar builds through to substantial modern detached homes on the roads around Corbets Tey and St Mary’s Lane. Getting glazing right here often means thinking carefully about scale and proportion.
DDG Windows offers a wide range of frame materials and styles to suit every type of property. Our team can guide you in choosing the perfect option for your home, balancing style, performance and budget.
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.
Upminster’s larger detached and executive homes are well suited to our aluminium window range – the slim sightlines and wide span of available sizes work particularly well on properties with generous elevations and picture windows. Available in any RAL colour, they’re a natural upgrade for homes that have outgrown their original white uPVC.
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.
For Upminster’s interwar and post-war semis, uPVC remains the most practical choice – offering strong thermal performance and low maintenance at a price point that makes sense. Our range includes options that sit sympathetically on older properties without compromising on modern performance.
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.
There are older cottages and period properties around Upminster’s historic centre and towards Cranham that benefit from our heritage window range. The steel-look profiles work particularly well on properties that want to retain an authentic appearance while gaining the benefits of modern glazing.

All our windows & doors are built in our Dagenham manufacturing site
With many of Upminster’s homes sitting on generous plots with formal front entrances and rear gardens opening onto extensions, doors here tend to be a considered choice rather than a quick replacement.
We supply and fit the full range across Upminster, from classic composite front doors to wide-spanning aluminium bi-folds for rear extensions.
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.
Aluminium bi-fold and sliding doors are a popular choice on Upminster’s larger homes, where kitchen extensions and garden rooms often call for wide, uninterrupted openings. Made to measure at our Dagenham site, they’re fitted by our own installation team with minimal disruption.
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 consistently popular choice across Upminster’s interwar and post-war properties – robust, low maintenance, and available in panel styles that suit the area’s predominantly traditional streetscapes. Competitive lead times from our Dagenham manufacturing base.
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.
Upminster homeowners looking to improve their front entrance without committing to timber maintenance consistently gravitate towards our GRP composite range. The moulded finish holds its colour and texture across decades, with panel styles ranging from traditional to contemporary.
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 Upminster, 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 Upminster and the surrounding areas, including Cranham, Corbets Tey, North Ockendon, Hornchurch, Emerson Park, Rainham, South Ockendon and the wider RM14 postcode.

Upminster is practically on our doorstep – our Dagenham manufacturing site is just a few miles away, and we’ve been working across this part of outer East London and Essex for over 40 years.
We know the housing character well, from the solid interwar semis closer to the station to the more substantial detached homes towards Corbets Tey and Cranham, and we understand what glazing choices work for each.
Upminster doesn’t have widespread conservation area restrictions, but the village centre and certain older streets have their own character that’s worth respecting when choosing replacement glazing.
We’ll always advise on what products and finishes suit the specific property and location, rather than defaulting to whatever’s most convenient.

Our people are at the heart of everything we do. Many of our team members have been with us for decades, working alongside younger innovators to ensure DDG stays ahead with cutting-edge machinery, contemporary design, and expert craftsmanship.

Experienced. Dedicated. Customer-focused. Our directors and senior management team lead with decades of experience in window and door design, manufacturing, and installation. Based in London and Essex, the DDG leadership team oversees every stage of production, ensuring quality craftsmanship, efficient service, and customer satisfaction on every project.
Skilled. Reliable. Proud of their craft. From our expert fabricators and finishers in the workshop to our professional fitters, installers, and delivery drivers, every member of the DDG team plays an essential role. Their precision and attention to detail ensure your new windows and doors are expertly crafted, installed, and finished, right here in our London factory and fitted across homes throughout the UK.
Usually within 48 hours of your enquiry or site visit. Our Dagenham base is just a short drive from Upminster, so we can arrange surveys quickly and get written quotes turned around without unnecessary delays.
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 Upminster 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.
Yes - every aluminium window, UPVC window, door and roof lantern we fit across Upminster is installed by our own fully trained and accredited team. We never subcontract, which means the same standards apply on every job regardless of where in the county you're based.
Absolutely. We regularly work on larger detached homes across Upminster and the surrounding area, including full window replacements, aluminium bi-fold installations for rear extensions, and roof lanterns for garden rooms. Everything is manufactured at our Dagenham site so there's no constraint on size or configuration - we work to the exact dimensions of your property.
For many of the larger and more premium homes in Upminster, yes. Aluminium windows offer slimmer sightlines, a wider range of RAL colours, greater strength for larger spans, and a finish that holds its quality over decades without the fade or discolouration that older uPVC can suffer. For a standard semi, the premium may not be necessary - but for a larger detached home where aesthetics and longevity matter, aluminium is often the better long-term investment. We'll give you an honest comparison during the consultation.
