Window Installer FAQs

how much is double glazing?

Double glazed windows are one of the most popular window options for home and property owners in the United Kingdom and reasonably so. They are able to offer a wide range of benefits to home owners which includes being energy efficient, reducing the build up of condensation on windows and black mould growth, significantly reducing background noise for a better relaxation or night rest, increasing the value of your property as well as adding to the aesthetic appeal of your home. So if you’ve decided to lay your hands on a double glazed window, you’d probably also like to know how much it’s going to cost. Well, providing a simple and accurate answer to the question of double glazing window cost is almost impossible as there are so many factors that influences the price including the materials and style.

Several suppliers usually provide the list of their double glazing windows on their websites, however these prices are only for basic off the shelf window and most often without the installation cost. Furthermore, if you require some special features to your double glazed window, then this will also tell on the total cost of the window.

So how much will a double glazing window cost? The cost of a double glazing window usually ranges between £100 to £3,200 per window, depending on the available options.

To have a more accurate estimate of the cost of a double glazing window, you’ll need a obtain a survey from a double glazing installer who can take into account any possible complications that may arise when installing your windows while also giving an advise on the most suitable window style for your property.

Will a new double glazed window look different to existing ones?

It depends on a few factors whether a new double glazed window will look different to existing ones. If your existing windows are very old, perhaps 10 years or more, then it’s likely that there will be some small differences.

The first thing to remember is that your double glazing is exposed to the elements as soon as it’s installed. So over time, unless you’re very good at cleaning and maintaining your windows, they’re likely to look a bit dirty. Window frames that are south-facing may also become slightly discoloured from the sun, so if you install a new window right next to it you might notice a difference.

Also, there have been lots of technical advances in windows over the years. If your existing windows are significantly older, you might notice a difference in the handles on openers, and if your existing windows were installed before 2010 they might not have trickle vents, which is an extra strip on the inside of your window to keep air flowing through your home. While it’s not a legal requirement for replacement windows to have trickle vents if the original one didn’t, it’s a good idea to have them installed as they help prevent condensation and mould.

The only truly noticeably different elements to a new double glazed window compared with existing ones are likely to be on the inside, which might not be a problem for you if you only have one window in a room. However, if you know the brand of your existing windows, you can ask your window installer if they can source the same ones. Even if they’ve been updated slightly, the difference should be minimal.

what is a porch?

A porch is a small and low structure (with a roof) located at the main entrance of a building or house. It’s typically without a window (although newer variations may come with one) and can either be screened-in or enclosed to prevent unwanted access from insects and extremes in weather. In addition, some homes may have a three-season porch or sun porch. This may be situated by the side of the house and covered by the roof overhang - they’re usually screened in to offer good access all year round.

Generally, porches serve a wide range of purposes. They include:

• Provision of an outdoor living space to relax during the summer months

• It’s an informal extension of the the living room.

• It serves as a great place for social gatherings especially in small towns.

• You can take off your dirty shoes and dry a dripping wet dog before entering into your living room.

• It can be incorporated for relaxation purposes and watching street activities.

• It can serve as a reception area for guests.

• It can also be used for outdoor storage.

Pros & Cons Of A Porch

Pros

• Due to the fact that they’re covered, porches may require little maintenance practices.

• It can go a long way to improves the curb appeal of your property.

• It protects against the extremes of the weather.

• It can be constructed using a wide range of materials.

Cons

• It does not improve the use of the property

• It can be quite expensive to install depending of the material required as well as size of the porch.

• It does not add to the value of the home unlike several other home improvement projects

• It may not be safe to be used by a child or pet.

Are coloured double glazing windows more expensive than white ones?

Coloured double glazing windows are more expensive than white ones, in general. uPVC is the cheapest material to use for double glazing, and white is the standard colour. But there are endless possibilities in terms of colours you can have, and they do come at additional cost.

Some people choose to have coloured double glazing that matches or opposes the colour of the exterior of their house. Another popular option is a woodgrain effect, which from a distance looks just like more expensive timber windows. The best thing about a wood effect is that you can have the stylish look of wooden windows without the maintenance, and they should last longer.

While coloured double glazing is more expensive than white ones, it doesn’t have to break the bank. The best thing to do is get in touch with a range of window companies and ask them to come round to give you a quote. They should be able to offer you brochures or links to websites of different brands of windows that offer coloured frames. From there, you can decide on the installers you liked most and the brand you preferred.

It’s worth bearing in mind that it’s not always best to go with the cheapest coloured windows. While there lots of good, inexpensive options out there, sometimes very cheap windows won’t be good quality and may not last as long as other slightly more expensive brands. Speak to your installer about guarantees that may come with the windows and how long they would expect them to last before making your final decision.

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.
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.

What happens to my old windows?

After fitting your new windows, your installer should take away and dispose of your old windows. If you want to keep them, just let your installer know before they start work. The UPVC frames are melted down and used on the unseen parts of new windows. Aluminium frames are re-smelted and wooden are broken down and used as chipboard.
