When Does Double Glazing Need Replacing?

when does double glazing need replacing

Your home cannot talk to you. However, your home can still give you signs when something is not right. The windows, for that matter, are very communicative. High-quality and well-maintained windows can last for up to 20 years.

However, there are many factors you need to take into consideration before you consider whether it’s time for an upgrade.

With that in mind, when does double glazing need replacing? And what are the signs that your home is sending to you? It’s time to find out…

What Is The Lifespan Of Double Glazed Windows?

We said that quality windows can last up to 20 years. When you add double glazed windows to your home, keep in mind that over time, they will inevitably need replacing.

Put simply, sealed, double-glazed windows have a limited lifespan. The seal will eventually fail, which results in the two panes of glass misting up. When you install high-quality windows, that might not happen for 30 years. But the general rule of thumb is that double glazed windows should last for 20 years.

However, that applies only if they are properly installed. A poorly installed window might fail sooner. Sometimes, a poorly installed window might fail after just one year. And that would come as a shock. Especially after you’ve spent so much money on your new windows.

When Should You Replace Double Glazed Windows?

In most cases, replacing double glazed windows is a matter that requires immediate attention. You do not want your windows not functioning properly. However, if you can wait a little bit, there is actually a “best time of year” for replacing windows.

During the winter, contractors’ schedules are less hectic, and they can pay more attention to the problem. And because they have less work, you might negotiate a small discount as well.

Contractors aim to secure jobs before Christmas, making it a perfect time of the year to leverage a discount. Therefore, for a cosy Christmas, get your windows replaced if they’re showing signs of wear and tear.

When draughts appear in or around the window, that means a seal has broken down. Luckily, you do not need to replace the windows, as a good remedy is filling the area between the wall and the frame

How To Check If Your Double Glazing Has Failed

When does double glazing need replacing? Well, as mentioned previously, your home will send you several signals that something is not right. Double glazing windows are efficient, but even they have a limited lifespan. You need to look for leaks, condensation, cracks, and draughts.

Water leaks are among the first signs that your windows need replacing. If the leak is coming in via the frame, it might be a result of a failure of the window’s weather seals.

Or it might be that the drainage is blocked. You can replace the weather seals, but make sure to contact your window supplier. In this case, you do not need to replace the entire windows, just the seals.

Condensation is another problem that might occur when your windows are past their prime. Condensation forms inside because of poor ventilation, use of the room, and the temperature inside and outside.

Double glazed windows are great at preventing condensation. But as they age, their level of performance is greatly reduced. You can try improving the ventilation, and if that helps, there is no need to replace the windows.

If that doesn’t help, it might be time to replace the windows. You need more energy efficient windows that will reduce condensation, thanks to the internal pane of glass being warmer.

Cracks, holes, and scratches in the glass of the window are all signs that replacement’s required. Replacing the glass is the only remedy that will solve the problem. Leaving the cracks, holes, and scratches will cause condensation between the panes, and reduce the overall efficiency of your windows.

When draughts appear in or around the window, that means a seal has broken down. Luckily, you do not need to replace the windows, as a good remedy is filling the area between the wall and the frame.
