We work with homeowners, developers and commercial clients across Brentwood, offering a full range of glazing solutions – from sleek aluminium frames to low-maintenance UPVC systems. Brentwood is a regular part of our Essex coverage, and our Dagenham manufacturing base means we can offer competitive lead times and a team that knows the area well.
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.
Brentwood is one of Essex’s most popular commuter towns, with a housing stock that reflects its status – a significant proportion of larger detached and executive homes, particularly on the roads towards Shenfield and Hutton, alongside more standard interwar and post-war semis in the central residential areas. It’s a market where quality of finish matters, and where homeowners invest thoughtfully in improvements.
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 the premium window choice across many of Brentwood’s larger detached and executive homes, where slim profiles, wide sizing options and a premium RAL finish complement the quality of the surrounding property. An increasingly popular upgrade as homeowners move away from ageing 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.
uPVC is the practical choice for Brentwood’s standard residential stock – the interwar semis and post-war detached homes that make up a large proportion of the town’s housing. Reliable, low maintenance and well priced, with modern finishes available well beyond standard white.
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.
Parts of Brentwood town centre and the surrounding older streets have period properties that benefit from our heritage window range. Made to order in bespoke sizes and colours, the steel-look profiles preserve the character of older homes while delivering modern thermal and security standards.

All our windows & doors are built in our Dagenham manufacturing site
Brentwood homeowners tend to invest carefully in their front elevation - a quality entrance door on a well-maintained Brentwood property makes a significant difference to kerb appeal and first impressions. We supply and fit the full range across Brentwood, from premium aluminium entrances on executive homes to composite and uPVC solutions for the broader housing stock.
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 Brentwood’s executive and larger detached homes, where rear extensions and garden rooms call for wide, high-performance glazed openings. Made to measure at our Dagenham site with short lead times.
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 Brentwood’s standard residential stock – durable, low maintenance and available in a wide range of panel styles and finishes. Competitive lead times from our nearby 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.
Very popular across Brentwood’s large stock of detached and semi-detached homes, where a quality front door in a traditional or contemporary finish makes a real difference. Available in a wide range of colours to suit the area’s varied housing stock.
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 Brentwood, 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 Brentwood and the surrounding areas, including Shenfield, Hutton, Ingrave, Ingatestone, Pilgrims Hatch, Warley, Kelvedon Hatch and the wider CM13 and CM14 postcodes.

Brentwood is a regular part of our Essex coverage, and a town we’ve been working in for decades.
We know the contrast between the executive homes around Shenfield and Hutton and the more standard stock in the central residential areas, and we understand what glazing choices suit each property type in this market.
Brentwood has a relatively straightforward planning context for most residential properties, but there are older streets and some conservation-sensitive locations where product choice matters.
Our team will advise on any relevant considerations before recommending a product, and our heritage range is available where period-appropriate glazing is required.

Usually within 48 hours of your enquiry or site visit. We serve Brentwood regularly from our Dagenham base and can arrange surveys without significant 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 Brentwood 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 Brentwood 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 it's a common request in this area. We can supply and fit a full glazing package across a larger Brentwood home - aluminium windows, bi-fold or sliding doors and roof lanterns, all manufactured to measure at our Dagenham site. A single site survey covers the whole project and we'll produce a consolidated quotation.
Yes. We work with both private homeowners on completed new build homes and with developers during the build process. For new build projects we can work to architects' specifications and building regulations requirements, supplying and fitting to the relevant thermal and security standards.
