How Long Do Timber Windows Last?

Timber windows have a lot of great benefits and qualities that they can add to a property, and although they do cost a bit more upfront, you’ll get a lot more out of timber windows than popular alternatives. On average, timber windows can last between 60 and 80 years, whereas a popular window alternative, uPVC, can last between 10 and 35 years. To put that in perspective, if you had new windows in 2005, you might need to think about getting them replaced already!

What makes timber windows last?

Timber has been used as a building material for over 10,000 years and is one of the longest-standing building materials in existence, so we know there are some great benefits to using it! Timber is a highly durable material, and durability can be measured and rated, thanks to TRADA’s Timber Durability Chart. 

Part of what makes timber, and wood in general, a durable material is its ability to absorb and release moisture and be resistant to conditions and chemicals that can affect a timber alternative, including aluminium, such as the salt in the sea air or drastic weather changes. 

The density of timber also makes up for its durability, as this provides strength within the material. To get a bit technical, it’s a natural polymer, so within the timber, you’ll find parallel strands of cellulose fibres held together with lignin, making the wood ridiculously strong. The more of these fibres, the denser the wood, the stronger it is!

What about the cost?

Timber is a natural material, and therefore it will cost a touch more. Depending on the type of timber you use, hardwood or softwood, it can also be a factor for the price because softwood timber grows quicker. 

The average home in the UK has around 10 windows, averaged from around 2 windows per room, and the average cost of a uPVC window in 2021 will be anywhere between £250 - £900, depending on the size and story of your home, so let’s average the cost at £650. On the other hand, if you’re looking at purchasing timber windows, you’re looking at a price between £850 - £1500, so we’ll average it at £1100. For a complete set of uPVC windows on an average house, you’re looking at £6,500, whereas for timber windows, it’ll set you back £11,000. It seems like a lot, yes, but, say your uPVC windows last 20 years, that’s £715 p/a. Timber Windows last an average of 70 years, meaning that your windows will only cost you £345p/a. Well worth the investment when they look better as well as last longer.
