Why choose timber sash windows
Timber sash windows are the natural choice for period properties, conservation areas and anyone who wants a genuine, authentic finish.
- The most authentic look for Victorian, Edwardian and period homes
- Often the preferred or required choice in conservation areas
- Modern double glazing and draught-proofing for warmth and quiet
- Made from sustainable, high-quality timber
- Can be painted or stained in any colour to suit your home
- Traditional joinery and hardware for a true period finish
Timber or uPVC sash windows
Timber gives the most authentic finish and is often preferred for period and listed properties, though it needs occasional repainting to stay at its best. uPVC sash windows offer a similar look with lower maintenance and better value. We will help you weigh up the right choice for your home and, where relevant, any conservation requirements at your free survey.
Finishes and options
- Painted or stained in any colour, including heritage shades
- Traditional run-through sash horns for period authenticity
- A choice of glazing bars and astragal options
- Period ironmongery and traditional fittings

Frequently asked questions
Are timber sash windows suitable for conservation areas?
Yes. Timber is often the preferred or required material in conservation areas and for listed buildings, as it keeps the authentic period appearance. We can advise on local requirements at your survey.
Do timber sash windows need much maintenance?
They need occasional repainting or restaining to protect the wood, but modern timber windows are treated to last and require far less upkeep than older windows. In return you get the most authentic finish available.
How much do timber sash windows cost?
It depends on the number of windows, the size, the finish and the glazing. We give a fixed written price after a free survey rather than a misleading average. Request a quote for an exact figure.
Are your windows FENSA registered?
Yes. Every installation is FENSA registered and certified as compliant with building regulations, with a certificate provided on completion.
