How to replace the glass in a uPVC window?

It’s not too difficult to replace the glass in a uPVC window, so if you’re a confident DIYer you could have a go at this yourself. We’ll go through the main steps on how to replace the sealed unit in a uPVC double glazed window: Using a rubber mallet and a strong pallet knife, remove the beading around the window. You might think they’re part of the frame, but they’re actually separate on the inside of the frame and can be taken out by using pallet knife to prize them out. Start with one of the longest beads first and leave the top bead until last. Give the glass a little tap to loosen it if it doesn’t come out straight away, then the whole unit should slide out easily. Just make sure it falls towards you and not back out onto the ground below! Clear any debris that has found its way into the frame with a brush. Add spacers at the bottom of the frame – these could be pieces of plastic. Get your new sealed unit (make sure you measure the glass before you buy one so you know which size to get) and carefully take it out of the packaging. Look for the British Standard mark – that shows you the bottom of the glass. Lift the glass into the frame, starting with the bottom first, and make sure that it fits square in the frame before taking the spacers out. Use a little washing up liquid to spread along the beads to make it easier when you slide them back into the frame. If they simply push and clip back in, you can use something like a block of wood to help you push them in correctly. Put them back in reverse order to how you took them out. And there you go! If you’re feeling confident you can have a go at replacing the glass in your uPVC window yourself. But if you’ve got any worries, leave it to a window installer who will be able to do it in less than an hour.

FAQs

You can only repair blown double glazed windows in the sense that you can replace the sealed unit (the glass part of the window) instead of having to replace the entire window.

When a double glazed window is blown, it means that the seal around the window has failed and is now letting air in and out. Often the first sign that the sealed unit has blown is condensation on the inside of the window, which is annoying since there’s no way to get rid of it! When your sealed unit has blown, you’ll be losing heat out of the window, meaning you could be spending more on your energy bills.

As a temporary fix, you could see if you can buy a misting repair kit online, but the condensation will eventually occur again as the air gets in. The best thing to do is ask a window installer or glazier to replace the sealed unit for you.

It's simple to replace the glass in a window – the specialist will remove the beading around the window, remove the blown glass from your window frame and set it to one side. They will then clean up around the frame before adding spacers in, then fitting the new sealed unit into the frame. They’ll make sure it’s a snug fit before replacing the beading back around the window to secure it.

There's no reason to put off repairing a blown double glazed window since the cost is generally much less than replacing the entire thing. A sealed unit with installation costs an average of £100, whereas a completely new window will cost around £400. You’ll soon notice that it’s less draughty and will be able see out of your window once you’ve had the blown glass replaced.

You can end up with a cracked glass window in a few ways. The most common one is when a rogue stone in the lawnmower hits the window or someone’s cricket or tennis game goes wrong and you end up with a ball through the window. Youi often end up with a ‘bullseye’ type crack that expands out from the point of impact. You can also get pressure and stress cracks from intense fluctuations in pressure and temperature. Unfortunately, there’s no way you can permanently fix cracked windows without replacing the entire sealed unit. An installer can replace a cracked glass window in less than an hour simply by taking out the sealed unit (the two panes of glass in double glazed windows) and replacing it with a new one. It costs an average of £110, but you could try to do it yourself for around £55. But what if you can’t get an installer to fix your window straight away? There is a DIY method you could try. As a temporary fix for your glass window, you can use a solvent-based adhesive like epoxy which will keep the glass intact and prevent further damage. You’ll also need:

Washing up liquid
Glass cleaner
A lint-free cloth or rag
A putty knife
A paper plate
Acetone

First, you’ll want to clean the glass using the washing up liquid and a damp cloth to remove any dust or oils. Leave it for a few minutes to dry, then create a mixture of epoxy by combining the hardener and the resin and stirring it on a paper plate. Using the putty knife, spread the mixture on the cracks, making sure you press gently to fill them. Leave it for at least 5 minutes to dry, then get rid of any excess by using some acetone on a dry cloth. Clean the window using some glass cleaner and another dry cloth, and you should have a temporary fix!

It’s not too difficult to replace the glass in a uPVC window, so if you’re a confident DIYer you could have a go at this yourself. We’ll go through the main steps on how to replace the sealed unit in a uPVC double glazed window:

And there you go! If you’re feeling confident you can have a go at replacing the glass in your uPVC window yourself. But if you’ve got any worries, leave it to a window installer who will be able to do it in less than an hour.

Accidents happen, and sometimes windows get broken. And that will lead to you wanting to replace just the glass in your window, rather than the whole frame. Also, as windows get older they can mist up on the inside, which means that the unit has ‘blown’ - so you’ll also need to replace the glass. But how much is it to replace the glass in a window? Luckily, if the frame of your window is in good condition, there’s no need to replace it, and this will reduce the cost. For an installer to fit a new pane of glass in a single glazed window, the average cost is £100, while a replacement double glazed sealed unit will cost an average of £110. Of course, as this is an average, if your window is very large you may spend more, and if your window is very small the price may be less. That's why it’s important to get a range of quotes so you can compare costs and get the best price. If you’re good at DIY, you may feel confident enough to have a go at replacing the glass in your window yourself. In that case, the cost of sealed unit and any other materials you need will cost an average of £57. It’s a significant saving, and if you think you can do it, then give it a try. However, if you’re in any way unsure, it’s best to leave it to the professionals. A window installer will be able to replace the glass in your window in less than an hour. Even though it costs more for a professional to do it, if you get it wrong and have to start over it will cost you more in the long run.
