Sash and Case Window Replacement
Sash and Case Window Replacement Across Dundee, Angus, Perth and Fife
Sash and case windows are a familiar feature on many older homes across Scotland, but original or ageing windows can become draughty, difficult to open or harder to maintain over time. For homeowners who want to improve warmth and comfort without losing the character of the property, replacement sash and case windows can offer a more practical way forward.
uPVC sash and case window replacement is becoming a popular option because it can recreate the look of traditional sash windows while offering improved insulation, easier maintenance and modern glazing performance. At Doorquay, we help you choose sash windows that suit the age, style and proportions of your home before they’re measured, ordered and fitted by our joinery team.

TILT AND TURN window Benefits - why we love them
Traditional Style Windows With Modern Comfort
Sash and case windows are often chosen because they keep the familiar look of older Scottish homes, but modern sash windows can make them much easier to live with. For homeowners comparing uPVC sash and case windows with traditional timber sash windows, the main benefits are usually warmth, lower maintenance and a more reliable finish over time.
Traditional Appearance
uPVC sash and case windows can recreate the look of classic timber sash windows, with balanced proportions, sash-style detailing and finishes that suit older homes. This helps you improve your sash windows without losing the character that matters.
Lower Maintenance
Traditional wooden sash windows can need regular painting, repairs and upkeep over time. uPVC sash and case replacements offer a lower-maintenance alternative, helping you keep the sash window style without the same level of ongoing care.
Improved Warmth
Older sash windows can become draughty, especially around the frame, cords and glazing. Modern replacement sash and case windows can offer better insulation, tighter seals and improved glazing to help rooms feel warmer and more comfortable.
Easier To Function
Original sash windows can become stiff, heavy or difficult to open properly. Modern sash and case replacements are designed to operate more smoothly, giving you the look of traditional sash windows with a more reliable feel in use.

Sash and Case Window Design Options
Details That Keep the Sash Window Look
Sash and case windows are all about proportion, detail and balance. From frame finish and sash-style detailing to glazing bars, hardware and colour, the right choices can help your replacement sash windows feel in keeping with the property while improving comfort and performance.
Modern uPVC windows can be designed to recreate a more traditional sash window appearance, with woodgrain finishes, softer frame colours and carefully chosen details. This gives you a lower-maintenance option while still keeping the look of classic sash and case windows.
Glazing bars, sash horns, frame proportions and opening style can all affect how authentic the finished windows feel. We’ll help you choose details that suit the age, style and character of your home.
Handles, locks and hardware finishes can make a noticeable difference to the final look. Whether you want your sash windows to feel traditional, understated or slightly more modern, we’ll guide you through colour and finish options that work with the property.
