We work with homeowners, developers and commercial clients across East Finchley, offering a full range of glazing solutions – from sleek aluminium frames to low-maintenance UPVC systems. From our Dagenham base we serve North London extensively, with teams well versed in the property mix found across N2.
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.
East Finchley is a well-established North London suburb with a strong stock of interwar semis and detached homes, alongside Victorian and Edwardian terraces closer to the high road and tube. It’s an area where homeowners invest significantly in their properties, and where glazing choices – particularly on the more characterful older homes – merit careful consideration.
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 East Finchley’s larger interwar and Edwardian homes, aluminium windows are an increasingly popular upgrade – slim profiles, a wide choice of finishes, and a quality that suits homes where the overall standard of improvement is high.
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 a practical and popular choice across East Finchley’s terraced and converted stock, and for interwar semis where performance and value are the priority. Our range covers both traditional white and contemporary coloured finishes to suit properties across N2.
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.
East Finchley and the surrounding Barnet area have a number of conservation zones and Article 4 properties where original window profiles should be maintained. Our heritage range is the appropriate solution in these situations, replicating the steel-look aesthetic of period windows in modern, thermally-efficient materials.

East Finchley’s mix of period and interwar properties calls for a considered approach to door replacement. We supply and fit the full range across N2, with guidance on what works best for the character and planning context of your specific home – from composite front doors to premium aluminium entrances and bi-folds for rear extensions.
Whether you’re upgrading an original entrance or replacing something that’s simply past its best, our team will help you get it right.
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.
For East Finchley’s larger properties with rear extensions and garden access, aluminium bi-fold and sliding doors are a popular choice. The clean lines and wide configurations suit both older and more contemporary homes in N2.
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 solid and popular choice across East Finchley’s terraced and semi-detached stock – available in panel styles that suit period properties and more modern homes alike, with competitive pricing and fast turnaround from our Dagenham site.
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.
The GRP composite range is a popular front door upgrade in East Finchley, particularly on the area’s Edwardian and interwar semis where a quality finish with minimal maintenance is the priority. Available in heritage and contemporary colour options.
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 East Finchley, 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 East Finchley and the surrounding areas, including Finchley Central, North Finchley, Barnet, Highgate, Muswell Hill, Fortis Green, Whetstone and the wider N2 postcode.

East Finchley is part of our regular North London coverage area, and we’ve built up solid knowledge of the property types across N2 over many years.
The mix of interwar semis, Edwardian terraces and larger detached homes is one we encounter frequently, and we understand what glazing solutions suit each property type both aesthetically and in terms of performance.
The Barnet area has active conservation zones in a number of locations, and East Finchley properties are not exempt from planning considerations that affect glazing choices.
Our team will check what applies to your specific property before making recommendations, so there are no surprises once you’ve committed to a product.

Usually within 48 hours. We cover North London regularly from our Dagenham base and can arrange surveys across N2 promptly.
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 East Finchley 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 East Finchley 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.
There are conservation zones in the Barnet borough that cover some East Finchley streets, and Article 4 directions in certain areas restrict the type of replacement glazing permitted. We'll check what applies to your specific address during the initial consultation. If restrictions apply, our heritage window range is usually the appropriate solution and we'll walk you through what that involves.
Yes, and it's exactly the type of project we're well set up for. We can advise on windows, doors and roof lanterns as a combined package, with products chosen to work well together aesthetically and in terms of performance. A single site survey covers everything and we'll produce a consolidated quotation so you can plan the project in full.
