How Often Should You Replace Your Sash Windows?

Here at Sash Windows London, we get many questions from our customers about our products and one of the most common is: how often should you replace your sash windows? So, I thought I would sit down and lay out all the information for you to help you make a fully-informed decision.

Although your windows cannot talk to you, there are some telling signs they need replacing. Although our beautiful sash windows don’t last forever, our sash windows are protected from timber rot and decay, paint and stain, hardware, glazing and workmanship. So, if you begin having problems with your sash windows, it is likely they are covered by the warranties above.

However, even high-quality windows like ours don’t last forever. In fact, the lifespan of your sash windows is affected drastically by the conditions you live in. For example, windows situated in coastal areas are likely to age faster than those in cities. If your windows are more than a few decades old, it is sensible to start checking for those tell-tale signs they need replacing.

Refurbish and Maintain Your Windows

Sash Windows Maintenance

Sash windows must be maintained and refurbished every decade or so to ensure they last for many years to come. Over the years, your sash windows will start to age and the glass may become loose in the sash box as a result of your house settling and moving around it, causing the timber window frames to expand and contract. These movements can cause gaps to form, reducing the energy-efficiency of your home and signifying the need for maintenance to be carried out. Maintaining your sash windows is very important as it can help keep the draughts at bay and maintain the smooth opening and closing of your windows.
