Window Installer FAQs

How much is it to repair the glass in a window?
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.
Will double glazing stop condensation?

If you’ve got a problem with condensation and don’t have double glazing, you should find that getting new windows will help. Condensation is caused by warm air meeting a cold surface which then turns into water droplets. With two panes of glass, less heat will escape from your home and keep the window warmer, meaning when steam from the bathroom or kitchen touches your windows there should be less condensation.

Can the glass in a double glazed window be replaced?
Yes, the glass in a double glazed window can be replaced. The glass in a window, or sealed unit to use its proper name, is not permanently attached to your window frames so if it gets damaged but your frames are still intact, there’s no need to replace the whole window. The glass in your double glazed window might need to be replaced due to:
  • Impact from a stone or other object smashing the glass in a ‘bullseye’ effect
  • The result of a break-in
  • Extreme weather or changes in pressure causing a crack
  • The sealed unit being ‘blown’, meaning that it’s no longer energy efficient due to air leaking out
A lot of window installers will replace the glass in your double glazing for you, but you might need to get quotes from specialist glaziers too. Glaziers deal purely with the glass in windows rather than installing entire frames. It won’t take a professional very long to replace the glass in your window. They will remove the beading from around the window with a pallet knife or chisel, leaving the top one until last to keep the sealed unit stable. Then, they simply lift out the glass carefully and will discuss with you whether the removal of the old sealed unit is included in their quote. Next, they will brush away any dust and debris that’s made its way into the frame and place spacers at the bottom. They will then lift the new glass into the frame, making sure it’s completely square. When they’re happy, they’ll remove the spacers and replace the beading back in reverse order. You’ll notice the replacement glass in your new window straight away as draughts should be eliminated and you’ll be able to see clearly again!
What to put over a broken window?
A broken window is a nuisance and an unwanted expense, and it can often happen at the worst times, like overnight when installers aren’t available or when the weather is very bad. So you might need to put something over your broken window as a temporary measure before someone can come and replace it – but what should you use? If you’ve got a small crack, you could try using some masking tape. Cover the entire crack with the tape making sure that there is extra tape at each end of the crack. This will help to prevent the crack from growing further. However, this isn’t going to work on large impact cracks or shattered windows. For a shattered window, you need to make sure you remove all the remaining glass as the shards could easily cut someone. To make a broken window like this safe, you’ll need:
  • Thick gloves
  • A hammer
  • A broom
  • A vacuum cleaner
  • Thick-soled shoes
  • Safety goggles
  1. Put your gloves on and use the hammer to remove the rest of the glass. Make sure you hit the glass away from you.
  2. Using the broom, sweep away any loose glass from the area, making sure you do both inside and outside.
  3. Use your vacuum cleaner to remove any small pieces of glass that you might not have been able to see.
Once you’ve cleared up the mess, you’ll want to cover your broken window with plastic and tape. It’s only a temporary measure so make sure you get in touch with a professional as soon as possible. Cut some heavy-duty plastic to fit the entire window. Using duct tape, secure the plastic over the window and make sure all the sides are sealed properly. It’s best to ensure that the plastic stays taught over the frame so it doesn’t get caught by the wind. Make sure you get in touch with a glazier or window installer as soon as you can – you'll notice a draught very quickly and someone could easily come and rip the plastic off. If you’re very worried about this you might want to add a chipboard over the top to make it more secure.

How can I find out how energy efficient my new windows will be?

All new windows come with an energy efficiency rating from A to G. A is best, while G is the lowest rating. Anything above C is considered good, but these days most companies will be able to supply you with A-rated windows to maximise your energy efficiency.

how does double glazing work?

One of the essential factors that makes a home truly a home is the convenience and comfort it provides us. As a result, we usually have a long to do list comprising things that come together to make sure our home is comfortable with ambient temperature at the very top of the scale of preference. After all, no matter how greatly designed your furniture and home decor is, it probably would amount for nothing if the temperature is either too hot or too cold. Some of the most common ways we incorporate to make the temperature a lot more conducive and warm during the winter months is by installing air conditioning system or through top notch insulation materials, but the fact still remains that a lot of heat would escape through the doors and windows. And that’s exactly the use of double glazing. So how exactly does double glazing work?

Double glazing basically works by preventing the escape of air and trapping it between two panes of glass. It’s the trapped air which serves as an insulation barrier which delivers 3 major functions. First and foremost, it stops the escape of heat through the window as the barrier created insulates the room from varying air temperatures at both sides of the glazing unit. The second major function is the double glazing works to keep down noise pollution coming from outside. While the third major function of double glazing I the fact that it helps minimize condensation which usually occurs on the single glazed windows’ inside as the cold outside air works to cool the warm air inside the house. When you install a double glazing window, the insulation barrier generated will work to stop the air temperature transmission which ultimately helps prevent the occurrence of condensation.

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:
  1. 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.
  2. 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!
  3. 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.
  4. 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.
  5. 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.
  6. 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.
