Superior Thermal Performance
Multi-chambered profiles and advanced glazing technology ensure maximum energy efficiency, reducing heat loss and lowering your energy bills throughout the year.

Choose from a wide range of colours, finishes, and styles to perfectly complement your home's architecture. From classic white to authentic woodgrain effects, we have the perfect match.
Long-Lasting Durability
Engineered to withstand the British weather, our uPVC windows won't rot, warp, or fade. Backed by comprehensive guarantees for complete peace of mind.
The right window style depends on your property type, the look you're after, and how you use each room. We supply and install all major uPVC window styles across Sunderland and Tyne and Wear, and our surveyors will recommend the most suitable option during your free home visit.
The most widely installed window style across Sunderland, casement windows are side-hinged and open outward. They suit most property types — from Victorian terraces to modern new builds — and offer excellent ventilation and a clean sightline.
The sash sits level with the outer frame rather than projecting proud of it — giving a flat, seamless appearance popular on contemporary new builds, barn conversions, and self-builds. Available in both casement and sash configurations.
Tilt-and-turn windows offer two opening modes: tilted at the top for secure background ventilation, or fully open inward for easy cleaning. Particularly popular for upper-floor windows in terraced and semi-detached properties.
Designed to replicate the look of traditional timber sash windows. Ideal for period properties and conservation-adjacent areas throughout Sunderland, with authentic details including run-through horns available.
Project outward from the wall, adding internal floor space, increasing natural light, and creating a distinctive external feature. A three-panel bay is the most common configuration for Sunderland semi-detached and terraced properties.
All replacement windows must meet Building Regulations Part L, which sets a minimum U-value of 1.6 W/m²K (C-rated). We install A-rated windows as standard — a U-value of 1.4 W/m²K or better, achieved through argon gas fill, warm-edge spacer bars, and a low-emissivity (low-e) coating that reflects heat back into the room.
For maximum performance, we also offer A+ rated triple-glazed units — see our triple glazing page. For a comparison with aluminium frames, visit our aluminium windows page.
Dual-colour options are also available — a different colour outside and white inside. Contact us for a full colour brochure.

Quality uPVC windows typically last 20–25 years before the sealed glazing units begin to fail. The frames themselves can last 30 or more years with minimal maintenance. All our installations carry a 10-year guarantee on products and workmanship.
It depends on your priorities. uPVC offers better thermal performance at a lower cost and suits most traditional Sunderland homes. Aluminium windows have slimmer sight lines and a more contemporary look — ideal for modern properties or larger glazed areas. We install both and can advise based on your property.
Often yes. Failed sealed units (condensation between the panes) can usually be replaced without changing the frame. Handles, hinges, and locks can also be replaced as individual components. If frames are warped, cracked, or badly discoloured, full replacement is usually more cost-effective. We'll assess your windows honestly during the free survey.
We supply and install casement windows, flush windows, tilt-and-turn, vertical sliding sash, and bay or bow configurations. Each style is available across the full colour range. See the styles guide above for detail on which suits each property type.
Yes. uPVC is a thermoplastic that can be recycled multiple times without significant loss of quality. Old frames are typically collected and reprocessed into new building products. Modern uPVC also contains no lead stabilisers, making it more environmentally responsible than older PVC formulations.
Common signs include condensation between the panes, draughts when the window is closed, difficulty opening or locking, visible warping or discolouration, and noticeably cold glass on mild days. If you notice any of these at your Sunderland property, contact us for a free assessment.
We recommend A-rated as a minimum — a U-value of 1.4 W/m²K or better, with argon gas fill and warm edge spacer bars. Building Regulations require a minimum C-rating, but A-rated is what we install as standard. For maximum performance, we also offer A+ rated triple glazing.

Fantastic experience with Lee from Range Windows. Prompt efficient service, windows swiftly measured up and date of installation agreed. Call on the day of installation to confirm the time and Lee arrived as agreed. Fab installation and exceptionally happy with the product. Will definitely recommend.

Had a new door fitted by Range Windows and Doors today, door looks amazing and service was brilliant. Everything was all cleaned up after the job was finished too which was a bonus. Highly recommended.

Definitely recommend this company! Service is 5 star, they try to help any way they can. Fitting me in to fit a low profile door so my wheelchair could get in my new home. The door is easy to work, draft free and feels very secure and solid. A very caring genuine company which is hard to find nowadays.

Adam and Brad came early, on time and got to work straight away. They worked hard, fitting 3 new bedroom windows then a back door — all finished in the day. Every item was installed well. They cleaned up everything inside and out, taking all rubbish away with them. Thank you for your good work.

Within a day Adam came to the house for a free quote — no pressure, no rush. Very professional and we chose this company just from how Adam represented them. Lee measured everything up within days, giving honest advice where other companies were saying to replace everything. Outstanding service.

I couldn't recommend these guys enough! Service was spot on start to finish. Lee and the guys are so knowledgeable about their products, even dropping off brochures so I could make a decision in my own time. No pressured sales, just down to earth people. Adam and Brad fitted the door — so professional.
