We work with homeowners, developers and commercial clients across Bishops Stortford, offering a full range of glazing solutions – from sleek aluminium frames to low-maintenance UPVC systems. From our Dagenham manufacturing base we serve Hertfordshire and the Stansted corridor regularly, with a team experienced in the area’s varied property stock.
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.
Bishops Stortford is a prosperous market town with a well-maintained housing stock that spans historic town centre properties, Victorian and Edwardian terraces, substantial interwar semis and a significant number of larger modern executive homes – particularly on the newer developments on the town’s periphery. The standard of improvement work here is consistently high, and glazing choices reflect that.
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 a popular premium choice across Bishops Stortford’s larger detached and executive homes, where slim profiles, wide colour choice and long-term quality match the standard of the surrounding property and street.
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 well-regarded choice across Bishops Stortford’s standard residential stock – the interwar semis and post-war detached homes that form a large part of the town’s housing. Available in modern finishes that sit well on the town’s characterful streets.
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.
Bishops Stortford town centre has a significant number of older properties, including listed buildings and conservation area homes, where our heritage window range is the most appropriate solution. Made to order in bespoke sizes and profiles to preserve original window character.

Bishops Stortford homeowners invest carefully in their front elevation - the town's well-maintained streets mean entrance doors are noticed. We supply and fit the full range across the town, with guidance on the right product for the character, planning context and budget of your specific home.
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.
For Bishops Stortford’s larger executive and detached homes, aluminium bi-fold and sliding doors are a popular rear door choice – particularly where kitchen extensions and rear living spaces benefit from wide, high-performance openings onto gardens.
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 Bishops Stortford’s standard residential stock – available in panel styles that suit both period and more modern properties, with competitive pricing and reliable lead times.
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.
Consistently popular across Bishops Stortford for both front entrances and rear doors, the GRP composite range offers the timber look without the maintenance – and in colours that work well on the town’s predominantly traditional streetscapes.
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 Bishops Stortford, 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.

Bishops Stortford sits on the Hertfordshire-Essex border and is part of our regular coverage area.
We’ve been working across the Stansted corridor for many years and know the town’s housing stock well – from the historic properties in the town centre to the executive developments on the periphery and the varied residential streets in between.
The town centre conservation area and the presence of listed buildings in and around Bishops Stortford mean that planning considerations are genuinely relevant for a proportion of properties here.

Usually within 48 hours of your enquiry or site visit. We serve Bishops Stortford regularly and can arrange surveys across CM23 without significant 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 Bishops Stortford 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 Bishops Stortford 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.
Potentially yes. The Bishops Stortford Conservation Area covers a number of streets in and around the town centre, and listed building status affects certain older properties. In both cases the type of replacement glazing that's permissible may be restricted. Our heritage window range is designed for exactly these situations - we'll advise on what applies to your property during the initial consultation.
Yes. The executive developments around the town's periphery are a regular part of our workload in this area - aluminium windows, bi-fold doors and roof lanterns are all popular choices on these properties. We work to the exact dimensions of your home and can handle a full glazing package from a single site survey.
