Every uPVC window we install is made to your home’s exact measurements – not a standard size forced to fit. That precision matters: a properly fitted uPVC window seals better, insulates better, and lasts longer than an off-the-shelf alternative.
Our uPVC windows use advanced multi-chamber profiles, which trap more air and reduce heat loss compared to older single- or double-chamber designs. If you’re comparing uPVC window prices against aluminium, uPVC remains the most cost-effective way to hit strong thermal performance without compromising on style.

Each uPVC window we install is built to order at our Dagenham factory in East London, sized precisely to your openings rather than adapted from stock sizes. That precision means a snug, weathertight fit and a neat finish inside and out.
Because we manufacture in-house, every stage is under our control. Frames are cut, welded and assembled by our own team, then inspected before they leave the factory, so installation day runs smoothly with no surprises or supplier delays.
All windows are available with double or triple glazing, a choice of glass (including acoustic, obscure and toughened), and a range of handle and hardware finishes.
From our base in Dagenham, we install uPVC windows for homeowners, landlords and businesses throughout East London and Essex, including Barking, Ilford, Romford, Hornchurch, Upminster, Brentwood, Chelmsford, Basildon and Southend-on-Sea, along with the boroughs of Havering, Redbridge, Newham and Waltham Forest.
Every survey, measurement and installation is carried out by DDG Windows™ staff. We never sub-contract, so the people who measure your home are backed by the same team who make and fit your windows.
Whether you’re replacing tired frames in a 1930s semi in Hornchurch, fitting sash windows in a period home in Brentwood, or upgrading a buy-to-let in Barking, we can help. We can also advise on conservation area requirements and Building Regulations compliance.
DDG Windows is a family-run business established in 1983. With over 40 years of experience in the fenestration industry, we have built our reputation on product quality, honest advice and installation that is done properly, the first time. We are not a national chain or a call centre operation. We are a local business with a genuine team, a real factory and real accountability to the customers we serve.
Cost depends on the number of windows, size, style, and glazing spec. Every quote is free and based on an in-home or video survey - get in touch for an accurate price, not a generic estimate.
Most homes are fitted within a day or two per window run, depending on scope. We'll confirm exact timings once your windows are surveyed and manufactured.
Both perform well. uPVC typically costs less and offers excellent thermal efficiency; aluminium suits slimmer sightlines and larger openings. We can talk you through which fits your home and budget.
Yes - uPVC windows work well on semi-detached and terraced homes alike. We'll advise on styles that suit your property's age and layout during your survey.
All our uPVC windows come with manufacturer-backed guarantees on frames and glazing. Full details are available on request or on our guarantees page.
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.
