We work with homeowners, developers and commercial clients across Haringey, offering a full range of glazing solutions – from sleek aluminium frames to low-maintenance UPVC systems. From our Dagenham base we serve North London regularly, with experience across the full range of property types found throughout this diverse borough.
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.
Haringey is one of London’s most varied boroughs in terms of housing character – from the Victorian and Edwardian terraces of Hornsey and Crouch End, to the interwar semis of Palmers Green and Bowes Park, through to the post-war estates and newer developments in Tottenham and Wood Green.
That variety means there’s no single right answer when it comes to glazing, and it’s exactly the range our team has spent over 40 years navigating.
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.
In Haringey’s more affluent residential areas – Crouch End, Hornsey, parts of Muswell Hill – aluminium windows are a popular premium choice for the Victorian and Edwardian homes that dominate these streets. Slim frames, wide colour choice and long-term durability suit homeowners investing seriously in their properties.
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 widely installed window type across Haringey’s large and varied housing stock, from the post-war estates of Tottenham to the converted terraces of Wood Green. Our range covers standard and contemporary finishes, all made to your exact measurements at our Dagenham factory.
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.
Haringey has several active conservation areas – particularly in Crouch End, Hornsey and parts of Muswell Hill – where our heritage window range is the appropriate product. The steel-look profiles work well on the Victorian and Edwardian homes that dominate these areas, and satisfy planning requirements where they apply.

Door requirements across Haringey vary as much as the housing stock itself – from heritage composite replacements on conservation area terraces in Crouch End, to aluminium bi-folds for extended properties in Wood Green, to practical uPVC solutions for the borough’s large stock of rental and converted properties. We cover the full range with guidance matched to the specific needs of your property.
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.
Aluminium bi-fold and sliding doors are popular across Haringey’s extended Victorian and Edwardian properties, particularly in areas like Hornsey and Crouch End where homeowners are making substantial improvements. Available in a full RAL colour range to match any property style.
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 practical and popular choice across Haringey’s large and varied housing stock – from terraced rentals to owner-occupied semis. Reliable performance, low maintenance and a competitive price point make uPVC the default choice for a significant portion of the borough.
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 composite range is consistently popular for front door replacements across Haringey’s Victorian and Edwardian terraces, where the timber-effect finish in heritage colours works naturally with the character of the streetscape.
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 Haringey, 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 Haringey, covering areas including Wood Green, Tottenham, Hornsey, Crouch End, Muswell Hill, Bounds Green, Palmers Green, Bowes Park, Turnpike Lane and the surrounding N4, N8, N15 and N22 postcodes.

We’ve been working across North London from our Dagenham base for over 40 years, and Haringey is a borough we know well in all its variety.
The contrast between the leafy Victorian streets of Crouch End and the more urban housing mix in Tottenham and Wood Green is significant, and it shapes what we recommend on every job.
Haringey has active conservation areas in several locations, and the borough’s planning department takes a particular interest in glazing on period properties in these zones.
Our team will flag any relevant considerations before recommending a product, and our heritage range is a common solution for properties in the conservation areas of Crouch End, Hornsey and Muswell Hill.

Usually within 48 hours of your enquiry or site visit. We cover Haringey regularly from our Dagenham base and can arrange surveys across the borough without long lead times.
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 Haringey 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 window, door and roof lantern we fit across Haringey is installed by our own trained and accredited team.
Conservation areas in Haringey - particularly in Crouch End, Hornsey and Muswell Hill - can restrict the type of replacement glazing permitted. In practice this often means like-for-like replacements in appropriate materials, which points to our heritage window range. We'll check what applies to your specific address during the consultation and advise accordingly.
Yes, regularly. Haringey has a large private rental sector and a number of active developers, and we work with both on glazing for single properties, multi-unit buildings and larger refurbishment projects. We can discuss volume pricing and phased delivery for larger projects.
