Replacement without compromise
New timber windows.
Familiar character.
Replacement sash windows should feel as though they belong to the property. The size of the meeting rails, position of the glazing bars, traditional sash horns and internal mouldings all help preserve the character of a Georgian, Victorian or Edwardian home.
We can discuss whether you need new moving sashes within sound existing frames, complete replacement timber windows or an assessment of whether restoration is more appropriate.
Talk through your replacement optionsWhat needs replacing?
The right answer starts with the existing windows.
Replacement doesn't always mean removing every frame. The condition of the joinery, the property and your aims determine which route makes sense.
Replace frames and sashes
Where frames have deteriorated or the openings need a more comprehensive solution, discuss fully made-to-measure timber replacements.
Keep what can be repaired
If original joinery remains sound or historically important, restoration may be preferable. A survey helps establish the appropriate option.

Profiles made to belong
Consider mouldings, glazing bars, sash horns and meeting-rail proportions alongside surviving original details.

Older homes & conservation areas
Respect the building before you replace the window.
The location and status of a property can affect the permitted window design, materials and glazing. Conservation-area and listed-building requirements aren't identical, and permissions may be needed before work begins.
Discuss the existing windows and any known restrictions with the team, and check the relevant requirements with the local planning authority before ordering.
What we'll discuss
- Original proportions and frame dimensions
- Traditional bars, horns and mouldings
- Suitable glazing and draught-sealing options
- Whether sash-only replacement or restoration is appropriate

Helpful to know
Replacement sash window questions.
Can I replace just the moving sashes?
Possibly. Where the existing frames are suitable, sash-only replacement may be an option. The condition and compatibility of the original joinery need assessing.
Do you supply real timber, not uPVC?
This page focuses on replacement sash windows made from hardwood timber, rather than plastic-look alternatives.
Can replacement sash windows be double glazed?
There are different glazing choices to discuss, but permitted specifications depend on the existing windows, the property and any planning or heritage restrictions.
Will the replacements match the original appearance?
Traditional profiles, bars, horns, fittings, colours and proportions can be considered to suit the original architecture.
How much will it cost?
Price depends on the number and size of windows, condition of existing joinery, material, glazing and finish. Request a tailored quote for an accurate assessment.
