We work with homeowners, developers and commercial clients across Collier Row, offering a full range of glazing solutions – from sleek aluminium frames to low-maintenance UPVC systems. Our Dagenham manufacturing base is just down the road from Collier Row, making us genuinely local to the area and well placed to provide fast turnaround and a familiar team.
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.
Collier Row is a predominantly residential suburb of Romford with a largely interwar and post-war housing stock – semis, terraces and some detached homes on the roads spreading out towards Harold Hill and Havering-atte-Bower. It’s a solid, well-maintained area where homeowners invest steadily in their properties, and where uPVC has long been the dominant window choice but aluminium upgrades are becoming more common.
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.
For the larger and better-maintained semis and detached homes in Collier Row, aluminium windows offer a step up in quality and appearance that’s increasingly popular as homeowners invest more ambitiously. Slim profiles and a wide colour range make a meaningful difference on properties that have previously had white uPVC throughout.
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 Collier Row’s large interwar and post-war housing stock, and for most standard replacement jobs it remains the practical, cost-effective first choice. Made to your exact measurements at our nearby Dagenham factory with competitive lead times.
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 any period or older properties in and around Collier Row where original window character should be maintained, our heritage range provides the bespoke solution. Less commonly required here than in some neighbouring areas, but available where it’s the right answer.

All our windows & doors are built in our Dagenham manufacturing site
We supply and fit the full range of doors across Collier Row, from standard uPVC replacements on the area's large interwar housing stock to composite upgrades and aluminium bi-folds for extended and improved properties. Our Dagenham site is nearby, so lead times are among the shortest available in this part of Essex.
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 a popular choice on Collier Row’s extended semis and detached homes, where rear kitchen and garden room projects open up ground floors to outdoor space. Fast turnaround from our Dagenham manufacturing site.
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 popular door type across Collier Row’s housing stock – dependable, low maintenance and very well priced given the proximity of our Dagenham manufacturing base. Available in a wide range of panel styles and finishes.
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 well-received front door upgrade across Collier Row, where the composite range delivers improved kerb appeal and security at a sensible price point. Available in styles and colours that suit the area’s predominantly interwar and post-war housing.
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 Collier Row, 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.

Collier Row is practically on our doorstep – our Dagenham manufacturing site is just a short drive away, and we’ve been working across the RM5 area for decades.
The interwar and post-war housing stock here is well maintained and the homeowner base invests steadily, and we understand what glazing choices suit the area’s property types and street character.
Collier Row doesn’t have significant conservation area restrictions for most properties, but we’ll always confirm what applies to your specific address before recommending a product. For the standard residential stock across RM5, the process is usually straightforward and we can move quickly from survey to installation.

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.

Usually within 48 hours - and often faster given how close our Dagenham manufacturing site is to Collier Row. We can arrange surveys across RM5 at 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 Collier Row 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 Collier Row 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.
Yes, and combining windows and doors in a single project is a common approach that saves time and reduces disruption. We'll carry out a single site survey covering everything, produce a combined quotation, and coordinate the installation so windows and doors are fitted in the most logical sequence. Our Dagenham site means a quick turnaround from order to installation.
For most standard Collier Row semis, uPVC is the practical and cost-effective choice - it performs well and represents good value. Aluminium is worth considering if you're doing a more ambitious renovation, if you want a wider choice of colours beyond standard white and grey, or if you're replacing large windows where the slimmer aluminium sightlines make a noticeable difference. We'll give you an honest comparison during the consultation so you can decide based on your priorities.
