Timber is the most traditional material for window frames and it can really add value and charm to your home. Particularly good if you live in a period home, timber windows are both elegant and classic. Timber is suitable for all types of window frames, including casement, sash and tilt and turn. But what’s the cost of timber windows?

The overall timber windows cost will depend on the style, timber, frame size and the number of windows you’ll need. As well as this, you need to factor in the installation cost. It might be something you attempt to DIY, but fitting windows is a specialist technical job and it’s important it is done correctly.

For a 600 x 900 mm timber casement window and the installation, you’re looking at an average price of around £925. For a 1,200 x 1,200 mm timber casement window, the average cost for the window and installation is around £1,200. Prices will vary depending on factors such as where you live (cities such as London will be more expensive), the quantity you buy and also the type of wood you choose.

It’s worth speaking to a professional to decide whether softwood or hardwood frames will be better for you. Softwood timber includes fast-growing pine, yew and cedar. They have good resistance to insect infestation and when properly maintained, they can have a longevity of up to 50 years.

Hardwood timber includes oak, beech and maple. The grain of hardwood is densely packed due to its slow growth rate. It’s more durable than softwood and can last at least 60 years, but it is more expensive.

Timber sash windows cost

Timber sash windows are a predominant feature of Georgian and Victorian properties, but they can also provide modern homes with an elegant appearance. A sash window opens and closes with a sliding mechanism and can open in different ways, but the most common design is a vertical opening. A horizontal sliding sash window is often called a Yorkshire sash.

Timber sash windows are elegant and space-saving and they can really improve the air-flow of your room, particularly with a double sash.

Wooden sash windows cost a little bit more than a standard casement window, but you are paying for the craftsmanship. For the window and installation of a 600 x 900 mm timber sash window, the cost is on average £1,490 per window. The cost of timber sash windows that measure 1,200 x 1,200 mm works out at around £1,640 for the window and installation.
