Replicating a heritage window depends on getting the proportions exactly right. Every window is built to order at our Dagenham factory in East London, with frame sizes, glazing bar positions and opening sashes matched to your property, whether that means copying original windows or designing something new.
Because we manufacture in-house, we can handle bespoke layouts that off-the-shelf suppliers can’t. Each window is checked before it leaves the factory, so it arrives ready to fit first time.
All heritage windows are available with double or triple glazing, a choice of glass (including acoustic, obscure and reeded), and a range of period-style and contemporary handles.
From our base in Dagenham, we supply and install heritage windows throughout East London and Essex, including Romford, Gidea Park, Ilford, Wanstead, Woodford, Brentwood, Chelmsford, Leigh-on-Sea and Southend-on-Sea, as well as the boroughs of Havering, Redbridge, Newham and Waltham Forest.
Our own team handles every stage, from the first survey to the final fit. We never sub-contract, so you deal with the same people from design through to installation.
Whether you’re replacing corroded steel windows in a 1930s house in Gidea Park, fitting steel-look glazing to a loft conversion in Walthamstow, or upgrading a period home in a Wanstead conservation area, we can help. We can advise on planning, conservation area requirements and matching original window designs.
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.
Heritage windows are aluminium windows designed to replicate the look of traditional steel windows from the Art Deco and interwar eras. They keep the slim frames, glazing bar grids and classic proportions of the originals, but with modern thermal performance, security and double or triple glazing.
No. Crittall is a brand name that has become shorthand for steel-framed windows. Our heritage windows are made from thermally broken aluminium to give the same distinctive look, while offering better insulation and no risk of rust.
Original steel windows are usually single glazed, lose a lot of heat, suffer from condensation and can rust over time. Heritage aluminium windows look very similar but are far more energy efficient, need minimal maintenance and meet current Building Regulations.
Often, yes. Because they closely match the appearance of original steel windows, heritage aluminium windows are frequently accepted in conservation areas. However, requirements vary between local authorities, and listed buildings usually need consent. We can advise on what's likely to be needed for your property.
The cost depends on the size, style, glazing bar layout, glass specification and number of windows. Because every window is made to measure, we provide a free, no-obligation quote after a home survey or video consultation.
Yes. As we manufacture in our own Dagenham factory, we can replicate original frame proportions, glazing bar positions and opening arrangements, or design a new layout to suit your property.
