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.
Where can I get one double glazed window?

Most window installers will be able to provide you with one double glazed window and fit it for you. If you’re replacing one double glazed window in your home, ask them to try and source the same windows that you already have or find one that’s very similar. Externally, you probably won’t be able to notice the difference, but if your existing windows are very old there may be some exterior discolouration and the locks and handles might look slightly different.

If you want one double glazed window so you can fit it yourself, there are lots of online companies that can supply you with one window. However, window fitting is a skilled trade and you might want to consider whether you have the right tools and experience to fit it yourself. Of course, you’ll save money on installation costs, but if something goes wrong, you might end up shelling out to get it fixed anyway.

The other thing to consider is that any replacement windows need to be certified that they meet Building Regulations. If you fit the double glazed window yourself, you’ll need to apply to your local council building control officer to get a certificate that confirms that you fitted the window within the regulations. You’ll have to pay a fee for this, and it will be even more expensive if Building Control say that the window hasn’t been fitted within the regulations and you have to start again.

The alternative is to ask a reputable window installer that is registered with a self-certification scheme, like FENSA, to install the window. That means that they can self-certify that the window meets building regulations once they’ve finished the installation.

What is uPVC?

uPVC is unplasticised polyvinyl chloride. It is a favourite amongst homeowners and manufacturers for its cheap production cost and excellent benefits. uPVC is used for window frames, conservatories and doors. In fact, uPVC can be three times cheaper than wooden frames and is also the most energy efficient option.As well as this, uPVC is now available in a range of colours other than the typically seen bright white finish. It can also be recycled, is durable and resistant to changing weather conditions.

How does Aluminium double glazing work?

Double glazing is made up of two layers of glass, with a layer of argon gas in between. This type of glass can be used in Aluminium windows. The gas is a poor insulator, helping heat to stay in your home and making your windows more efficient. As well as trapping the argon gas, the second layer of glass reduces the amount of noise that enters your property, and helps to make your windows stronger and more secure.

How to measure the glass for a window replacement?
If the glass in your window has been damaged, you might only need to replace that rather than your whole window frame. Common reasons for needing to replace the glass in your window include:
  • The glass has smashed from an impact such as a stone hitting it from a lawnmower
  • You have been broken into and suspects used the window to gain entry
  • The glass has blown (lost its airtightness) from constant water build-up around the seals, which is common in bathrooms
  • Extreme weather or pressure changes have caused a crack
If your frames are still intact and there’s nothing wrong with your window’s locks or trims, there’s no reason why you can’t just replace the sealed unit in your window. To help with the quotation process, a window installer may ask you to measure the glass for your window replacement. It’s pretty simple to just measure the sealed unit inside your window. There are just 3 steps you need to take:
  1. Including the beading (the plastic and rubber seals around the windows that can be removed), measure the width of the window frame.
  2. Do the same for the height of the window, making sure you include the beading.
  3. Then, take 10mm off each measurement, and you have the approximate size of your glass.
A reputable window installer will still make their own measurements before confirming the size of the glass in your window and going ahead and ordering the replacement. Make sure you get a range of quotes from local and national installers so you can compare the price and their quotation process.
How long do aluminium windows last?

How long your aluminium windows will last depends on their quality. They should last 20 -30 years at least, but have been known to stay in good condition for up to 45 years. This is considerably longer than uPVC and wooden double glazing.

What happens if I have problems with my new windows?

Ultimately the double glazing company you use is responsible for the quality of work and to ensure your windows are of an excellent standard. This is why it’s important to get a warranty and use a Fensa registered installer. If problems emerge within a couple of years then it’s likely the installation was of a poor standard.Contact the double glazing company and have the issue repaired or new windows replaced. This doesn’t matter if you received a discount of free windows as part of the deal. As long as you entered into a contract the company is obliged to restore the windows.

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.
