How long do timber sash windows last?

When it comes to the general perception of timber windows, many people have inaccurate and outdated views on their quality. Timber is often wrongly assumed to easily rot, warp and peel, but technological advances has meant that timber windows are now a reliable and long-lasting option for any property.

How long do timber windows last?

When they are well looked after, timber sash windows can last up to 60 years, which is double the lifespan of uPVC windows, which usually last around 30 years. Aluminium windows which have risen in popularity over the years have an expected lifespan of around 45 years, making timber the ultimate futureproof window material.
