We work with homeowners, developers and commercial clients across Dagenham – and we do so from our manufacturing facility right here in the borough. DDG Windows has been based in Dagenham since 1983, making us the most local glazing specialist you’ll find in RM8, RM9 and RM10.
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.
Dagenham has a distinctive housing character shaped by its history – the Becontree Estate, built between the wars as one of the largest council housing developments in the world, defines large parts of the borough with its interwar semis and terraces. Alongside Becontree, the wider Dagenham area has a mix of post-war housing, improved and extended properties, and a growing number of new build developments. It’s an area where we know every street.
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.
Aluminium is an increasingly popular upgrade on Dagenham’s improved and extended properties – a meaningful step up from the standard uPVC that’s been fitted across much of the borough over the past few decades. For homeowners investing in a full renovation, aluminium delivers a quality of finish that lasts.
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.
uPVC is the most common window type across Dagenham’s large interwar and post-war housing stock, and for most standard replacement jobs it remains the most practical option. We manufacture at our Dagenham site, so lead times are as short as they get – your windows are made around the corner from your home.
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.
For the older properties in Dagenham and any period homes in the area where original window profiles should be preserved, our heritage range provides a bespoke solution manufactured right here in the borough. Made to order in any size and colour.

All our windows & doors are built in our Dagenham manufacturing site
We supply and fit the full range of doors across Dagenham - and with our manufacturing site in the borough, we can offer lead times and pricing that genuinely reflect our local position. From standard front door replacements across Becontree to bi-fold installations for extended and improved properties, our team knows Dagenham and delivers accordingly.
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.
Aluminium bi-fold and sliding doors are popular on Dagenham’s extended semis and improved properties, connecting rear living spaces to gardens with wide, slim-framed openings. Manufactured on site in Dagenham, fitted by our own team.
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.
The most widely fitted door type across Dagenham – and with our manufacturing base here in the borough, the lead times and pricing we can offer are genuinely competitive. Available in a wide range of panel styles and finishes to suit any property across RM8, RM9 and RM10.
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 popular front door upgrade across Dagenham, where the composite range delivers improved kerb appeal and security in one step. Available in a wide range of styles and colours, and manufactured close to home at our Dagenham facility.
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 Dagenham, 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 carries out installations right across Dagenham, including Becontree, Chadwell Heath, Rush Green, Barking, Rainham, Hornchurch and the wider RM8, RM9 and RM10 postcodes.

There’s no glazing company in East London that knows Dagenham better than DDG Windows.
We’ve been based here since 1983 – our manufacturing facility is in the borough, our team lives and works here, and we’ve fitted windows and doors on streets right across RM8, RM9 and RM10 for over four decades. The Becontree housing stock, the post-war estates, the improved and extended properties – we know all of it.
Being based in Dagenham means our lead times are shorter, our local knowledge is deeper, and our commitment to the area is genuine rather than a marketing line. We’ve built our reputation here over more than 40 years, and every job in the borough is one we take personally.

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 - and often same day for straightforward enquiries given that our manufacturing site is here in the borough. We can arrange surveys across RM8, RM9 and RM10 at very short notice.
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 Dagenham 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 Dagenham 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.
If your Becontree property is leasehold - which applies to some former council homes that haven't been fully purchased - you may need to check with the freeholder before proceeding. For freehold owner-occupied properties, standard permitted development rights apply for like-for-like replacements. We're very familiar with the housing stock on Becontree and can talk you through any considerations that apply to your specific situation during the site visit.
The main advantages are lead time, local knowledge and accountability. Because we manufacture here in Dagenham, your windows and doors are made closer to your home than any national company can match - and if there's ever an issue, we're around the corner. We've been here for over 40 years and our reputation in the borough matters to us. You're not dealing with a call centre or a regional franchise - you're dealing with the people who make and fit your glazing.
