Window Installer FAQs

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 does one double glazed window cost?
How much one double glazed window costs is based on a few factors. If you just want to buy the window to install yourself, it will cost less than if you want an installer to fit it for you. If you want to simply buy one double glazed window without installation it could cost anywhere between £100-£300. That’s for a simple casement window, but other types like sash or tilt and turn windows could cost more. It’s recommended that you get a reputable installer to fit your double glazed windows because they’ve had the relevant training and will be able to install it much more quickly. How much it will cost for them to install one double glazed window will very based on your location, the type of window, how difficult the window is to access and whether you choose standard white uPVC or a coloured or woodgrain effect. An average uPVC casement window might cost somewhere between £300-£400, while a dual turn window might cost between £550-£660 to install. Do you really need to replace the entire window? If it’s just the double glazing that needs replacing, for example if it’s misted up inside, this will cost much less. Most window installers or a glazier will be able to just replace the sealed unit inside, and that may cost as little as £250. It’s always best to get a range of quotes from reputable companies so you know you’ve got a great price and you’re sure you’ll get excellent service.

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.

How much is a single window?
Sometimes accidents happen, and that leads to you needing to replace just a single window. Luckily, most window fitters are happy to replace just one window if you need to. But how much a single window costs will depend on a few factors. Firstly, do you need the entire window, including the frame, replaced, or just the sealed unit? If the frame is still in good condition, glaziers and some window installers can replace the sealed unit and this will set you back around £250. If your window frame is damaged, don’t try to get away with not replacing it. Having a broken window frame can let heat escape your home, increasing your energy bills, and you’re likely to hear more traffic noise. Plus, if the frame is broken you might have trouble closing the window properly, stopping you from keeping your home secure. So how much is a single window if you need the whole thing replaced? You should expect it to cost between £400-£550, but it could cost more or less than this depending on your location, the size of the window and how tricky it is to replace. There are other factors that will impact the cost of replacing a single window. Do you want the window to have plain, leaded or Georgian bar glass? Maybe it will be a casement window, or a bay, bow or sash? The cost will increase if you want more than one opener if it’s a large window, and if you want it to have locks. Also, the standard white uPVC frame colour will probably be included in the price, but if you want a woodgrain look or a different colour uPVC this will cost more.

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.

How long does it take to install one small double glazed window?

To install one small double glazed window, it will take anywhere between two hours and half a day. It will depend on whether one installer is fitting your window or two. And if you’re doing it yourself and don’t have any professional experience, it will take even longer.

When the window fitters arrive, they will make sure they’ve got safe access to the window and move any heavy furniture if they need to. Any good installer will lay down a dust sheet, but it’s a good idea to check that they’ve got one laid down before they start.

The first step any window installer will take is to double check the measurements of the new frame against your existing one. Hopefully it should match up, so then they’ll take the old window out. Then, they’ll insert the new frame into the aperture and bolt it into the concrete. They'll check it with a spirit level to ensure it’s even before moving onto the glass sealed unit.

The installer will place the glass into the aperture, then fit the beads to secure the glass in the frame. They’ll then use silicone and trim on the inside and outside to ensure the window looks perfect. You won’t be able to see where they’ve used sealants or trims because they’ll colour match them so it’s not noticeable. Then, they’ll tidy up all of their tools and the working area and let you know what needs to be done in terms of proving that the window meets building regulations. Most good installers are registered with a self-certification scheme, so will be able to issue a certification once the work is complete.

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.

Why are double glazed windows better than single glazed?

Double glazed windows are better than single glazed generally because they are more energy efficient. The clue’s in the name – double glazed windows have two panes of glass while single glazed windows only have one. In double glazed windows, there is a space between the two glass panes. This space is filled with inert gas or a tight vacuum, which helps to provide an extra level of insulation. That means that heat won’t escape your home easily, nor will it creep in, so you can keep your home at a more comfortable temperature.

The extra pane of glass also helps to increase your home’s security. Single glazing is pretty easy to smash through, whereas it will take much more effort to smash double glazing and will create more noise, so burglars might be put off.

Another reason why double glazed windows are better than single glazed ones is that they help to reduce noise. Of course, if you live by a busy road you’ll still hear some traffic noise, but it can be significantly reduced buy double glazing. In the same way that the inert gas in the middle of the two panes keeps heat in and the cold out, it also helps keep noise out.

With double glazing, you’ll also notice much less condensation. With single glazing, it’s common to see condensation on the inside of the windows, especially when the heating is on. This is because the outside of the window is cold, but the inside is warm. With double glazing, the insulation between the two panes stops there being such a difference in temperature between the inside and outside of the window.
