Window Installer FAQs

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.
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!
Will double glazing increase my property’s value?

These days, buyers expect homes to have double glazing. People recognise the benefits of installing double glazing, so if you don’t have it installed you should consider it. You’ll increase your property’s value and give it a better chance of selling faster, since single glazed properties are also more likely to have problems with damp and mould which could put buyers off.

how much are new windows?

Are you about to replace your old windows and wondering just how much it’ll cost to have a new one fitted? If yes, then you’ve come to the right place! The question is a very straight forward one, however a direct answer can not be provided as determining window prices for a replacement project can be a very tricky challenge. With a plethora of influencing factors that can play a key role in the price of both materials and labour to be used, it could be extremely hard for a window installer to provide a cost estimate without paying you a visit beforehand.

The factors that can go a long way in determining the price of your new window includes the size of the window, frame material, style chosen, your location, rates charged by the window installer (these rates can be different from an installer to an installer, so it’ll probably be in your best interest to compare quotes to identify the most competitive price) as well as the type of glass required.

Generally, for a small flat featuring four windows, the average cost for new windows would be between the range of £2,100 to £2,300. This range provided covers the cost of double glazed uPVC casement windows as well as the installation price. In the same tone, a home with up to 8 windows will have an average cost for window replacement between the range of £4,400 to £4,600, wile also taking into account the installation price. Whereas a house comprising 10 windows could begin at an average cost of window replacement between the the range of £5,200 to £5,500, and a 15 window home will be between the range of £8,400 to £8,600. it should be noted that the aforementioned figures only include the standard number of windows with a uPVC frame and the installation cost.

Should I get all my windows replaced at once?

You don’t have to, especially if you’re on a budget. If you’re only replacing some, it’s a good idea to get all the windows on one side of your property replaced at the same time, so they all look the same. Be aware, obviously, huge savings could be had by having a number of windows replaced at the same time.

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.

Do I need to stay at home while my windows are being replaced?

Most installers will not need you to be at home while they are fitting your windows. It is a good idea to be present though, just in case they have any questions for you and perhaps for your own peace of mind. If you cannot be there, you will need to arrange access to the property and/or agree securing the property at the end of the day.
