how to fit a double glazed window?

Did you just purchase a double glazed window and confused about how to have it installed? Fitting the window yourself can be quite easy with the help of this step by step guide. However, if you lack proper training or experience, we’d recommend you reach out to a trustworthy professional who can guarantee the best results for help. That said, now let’s take a look at the process.

• Remove the old windows by detaching the old beading and glass window safely. Then make some interval cuts using a hand saw before using a crowbar to pry it out.

• Cut the external double glazed window seal. Once done, take a measurement of the window area’s width once empty. Then transfer the measurement to the window sil to face outside and cut using a handsaw.

• Seal the window sil. Add a bead of clear silicone along both inside lip as well as the centre to seal the sil.

• Screw the double glazed window to the sil. Position the window on the top of the lipped section that was siliconed. Then pre-drill them together and screw in three places. You should make sure the screws do not go totally to the sil’s bottom.

• Install the double glazed window. After successfully screwing the double glazed window to the sil, you can now fit in the double glazing. Make use of packers to make sure it’s even in the slot.

• Screw the uPVC window to the wall. If you’re happy and satisfied with the position of the window, you can then pre-drill through the frame of the window and the brick wall. Once done, simply screw it in place using masonry screws or Spax screw as they do not require crawl plugs in bricks.

• Seal around the window. To do this, simply fill any gaps with expanding foam, wipe out the excess and seal with silicone.

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.

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.

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.

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 double glazed sealed units last?
When it comes to how long double glazed sealed units (the glass inside the window) last, a lot of it is down to the quality of the glass and the environment that your windows sit in. It’s not uncommon for your window frames themselves (especially if they are uPVC) to last longer than your sealed units. Sealed units are called that because they’re two panes of glass sealed together with an air gap in between. They use what’s called a ‘perimeter seal’ to protect the air gap between the panes, and is usually made of butyl mastic which retains a desiccant within a perforated metallic spacer bar. The desiccant’s job is to absorb any moisture which finds its way into the air gap to stop your window from misting up on the inside. When a sealed unit fails, or is ‘blown’, it’s usually because moisture builds up around the seal and causes it to fail. Sealed units won’t last forever, so you will eventually end up with condensation inside the panes of your double glazing, but in an ideal environment your double glazed sealed units could last up to 30 years, with some manufacturers claiming as long as 40 years. But they do require a bit of maintenance and the position of your windows will also make a difference as to how long they last. There are a few things that determine how long a sealed unit will last:
  • Climate - If your window faces south, it will be subject to direct sunlight for a lot of the day. This tends to cause the sealed unit to fail more quickly – a south-facing window may last between 10-25 years. This is because the spacer bars will twist as the temperature rises and causes the adhesive holding them together to eventually fail.
  • Moisture - Windows in kitchens and bathrooms tend to fail more quickly because they come into contact with moisture more often. For example, if water gets on your windowsill when you shower, the seal around the glass will come loose more quickly if it’s constantly wet.
When you replace the sealed units in your windows or get completely new double glazing, make sure you choose an installer that uses quality products and will take all the steps to ensure that your sealed units are kept away from moisture as much as possible.
