We work with homeowners, developers and commercial clients across Essex, offering a full range of glazing solutions – from sleek aluminium frames to low-maintenance UPVC systems. With our manufacturing base in nearby Dagenham, we’re well placed to serve the county quickly and efficiently.
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.
Essex is home to an enormously varied housing stock – from Victorian and Edwardian terraces in areas like Wanstead and Woodford, to post-war semis throughout Romford and Hornchurch, right through to newer builds and executive detached homes in towns like Brentwood and Chelmsford.
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.
Whether it’s a detached home in Brentwood or a period conversion in Wanstead, we manufacture and fit to the same exacting standard every time.
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.
Expect solid thermal efficiency and low maintenance, all at a competitive price. It’s no surprise uPVC remains one of the most popular choices among Essex homeowners.
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.
Made to order in bespoke sizes and colours, they’re a particularly popular choice on the period and conservation properties found throughout Essex, working just as well on a contemporary home as a traditional one.

All our windows & doors are built in our Dagenham manufacturing site
Doors take more wear than almost anything else in a home, so choosing the right one really matters. We supply and fit a full range of doors across Essex, with expert guidance every step of the way.
No matter if you’re replacing a tired front door, opening up your home to the garden, or securing a side entrance, our team will help you find the perfect solution.
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.
Particularly popular on newer Essex builds and extensions where clean lines and large openings are a priority.
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.
With a competitive price point and fast turnaround from our Dagenham manufacturing site, they’re a popular choice for homeowners right across Essex.
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.
A particularly popular choice for Essex homeowners looking to improve kerb appeal without committing to timber maintenance.
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 Essex, 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 Essex, covering towns and areas including Romford, Hornchurch, Upminster, Rainham, Brentwood, Chelmsford, Basildon, Harlow, Epping, Chigwell, Loughton, Wanstead, Woodford, South Woodford, Collier Row, Gidea Park and the surrounding areas:

DDG Windows has been operating out of Dagenham since 1983 – sitting right on the Essex border means we’ve spent over four decades working across the county, and we know its housing stock better than most.
Essex spans an enormous range of property types: the leafy suburban semis of Woodford and Wanstead, the interwar and post-war terraces of Romford and Hornchurch, larger detached homes in Brentwood and the commuter villages around Epping, and the newer estates spreading out towards Chelmsford and Basildon.
We also know that certain Essex areas come with location specific considerations – conservation zones in towns like Epping and Great Dunmow can affect what’s permissible, and period properties in areas like Wanstead often benefit from our heritage window range rather than a standard aluminium or UPVC replacement.
Our team will always flag anything relevant to your area during the quoting process, so you’re never caught out by planning or aesthetic constraints after the fact.

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. From Neil’s first home visits - with no pushy sales tactics, just honest quotes - to our installers who treat every property with respect, you’ll always feel supported and looked after.
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 site visit or email enquiry, you'll receive a full written quotation. Because our manufacturing base is in Dagenham - just over the Essex border - we can arrange site visits quickly and keep the whole process moving 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 Essex 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 Essex 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.
In many cases, like-for-like replacements don't require planning permission, but if your property sits within a designated conservation area - common in towns like Epping, Great Dunmow and parts of Wanstead - there may be restrictions on frame materials, colours or glazing bar styles. Our team will flag any potential considerations during your initial consultation, and we can advise on appropriate products such as our heritage window range that are designed to meet conservation requirements.
Absolutely. We regularly work on larger detached and semi-detached Essex homes where extensions, orangeries and garden rooms require oversized glazing, bi-fold or sliding doors, and roof lanterns. Everything is made to measure at our Dagenham site, so there's no standard sizing constraint - we work to the exact dimensions of your project.
