You might have often noticed the terms “sash windows” and “casement windows” being bandied about in reference to windows – and these terms do describe the two main types of house window available in the UK. These two types mainly differ in how they are opened and closed.

While sash windows comprise one or more panels – or “sashes” – usually shifted vertically, casement windows instead use side-mounted hinges enabling them to be swung open and closed like a door. We can install casement windows as well as sash windows.

Historically, sash windows were the traditional choice, and their popularity can be traced back to the seventeenth century. Hence, they are often the go-to option for older homes, at least aesthetically – though even casement windows are available in both traditional and modern designs.

Though casement windows have long benefitted from a tighter seal – and consequently better energy efficiency – than sash windows, this particular discrepancy has narrowed in recent years. Today, sash windows can give you a charming heritage design with modern technology built in.

This is a very difficult question to answer, as many different variables would be at play. For example, if you don’t choose from a standard size for your new timber sash window, making it would entail extra work in fabrication and fitting, thereby adding to the overall cost.

We don’t post a list of prices on our website, as it won’t be until after we have finished designing a timber sash window – and had that design approved by the client – that we will have a good idea of how much the window would cost us to manufacture, supply and install.

As we offer fixed-fee quotations, you can take heart that, if you do accept one of these quotes from us, the quoted price won’t change unless you have first agreed to a change to the previously finalised design. Our fixed-fee quotations therefore make it easier for our clients to budget.

However, we will only present you with a quote once we have:

• Held a free consultation with you
• Completed a free site survey at your home
• Recommended a specific type of timber sash window for you
• Received word from you that you want this specific solution

Though wood has been the traditional choice of material for sash windows, we are also capable of making and fitting uPVC sash windows – as you could be particularly heartened to know if you are concerned about wood’s reputation for picking up damage relatively easily.

Nonetheless, you should ask yourself whether your concerns about the resilience of wooden sash windows are well-founded. Timber is a tough material, meaning that it won’t easily diminish over time – provided you are diligent in looking after the wood, which is also elegant in appearance.

This will largely depend on the nature of the damage. While swollen or distorted woodwork, rotting frames, broken locks and damaged cords are common problems in such windows, our specialists in sash window repair can overcome all of these issues. 

Nonetheless, by replacing a timber sash window, you could tap into the following benefits:

• A longer-lasting window, as modern glass is more durable and hardwearing
• Upgraded glazing – for example, from single to double glazing
• A lower bill, especially if you originally wanted to repair a heritage window
