Window Installer FAQs

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 to fit aluminium double glazed window?

Whether you’re hiring a professional to replace your double glazing or are considering DIY, it’s a good idea to know how to fit a double glazed window.

You need to start by assembling your window. Fit any handles and cut the outer sill to size by measuring the outer wall depth. Then, screw the outer sill to the window frame and attach the frame fixers. Screw the ventilation grilles onto the inside of the frame and fix the vents on.

Next, you need put the window into place, using spacers to wedge it in. Use a spirit level to check it’s level horizontally and vertically, adding extra spacers if needed. Then, fix the frame into place at each fixing point using a drill, wall plugs and screws. Measure and cut the interior sill, and check that it’s level, adding spacers if needed. Then fix it using screws, masonry nails or adhesive.

Finally, fill in any wide gaps with foam filler and small gaps with sealant. You can get interior and exterior trims to cover these up, making your window look neat and professional.

How much could I save on my energy bills if I install double glazing?

As well as keeping your home warmer and reducing noise, you’ll notice a saving on your energy bills from installing double glazing. If you install A++ rated windows in your home after having single glazing, you could save up to £120 year on your energy bills. The Energy Saving Trust has more information.

How much is window repair?

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.

What is the Window Energy Rating (WER)?

The energy efficiency of windows is measured using ratings, varying from A, the most efficient, to G, the least efficient. This scheme is run by the British Fenestration Council (BFRC). To comply with Building Regulations you’ll need windows of energy efficiency at least level C.

Can you replace just one double glazed window?

Yes, of course! It’s common for people to replace just one double glazed window. One reason that people want to replace one window is that the sealed unit inside has failed. You’ll know if this has happened because you’ll be able to see condensation on the inside of glass, which gets frustrating because you can’t wipe it away. In this case, you can choose to simply replace the sealed unit or the entire frame, which you might want to do if it’s looking past its best.

When you’re replacing just one double glazed window, if you know the brand of your current windows you could ask your installer if they can source the same ones. This will help to keep them looking as similar as possible, although if your existing windows are very old you may notice some discolouration on the exterior compared to the new one, and locks and trickle vents might look different.

Replacing just one double glazed window shouldn’t take a qualified window fitter long, and could cost as little as £400. If you want to simply replace the sealed unit, that may only cost around £250. You could try to fit a new window yourself, but it’s worth bearing in mind that all replacement windows need to be certified that they’ve been installed to meet building regulations, so you’ll need to apply to your local building control officer who will come and inspect the work then issue a certificate. If you ask an installer who is registered with a self-certification scheme (like FENSA) to fit the window for you, they can issue the certificate themselves when they’ve finished the work.

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 to remove a aluminium double glazed window?

Removing a double glazed window can be quite labour intensive. If you decide to try it yourself, make sure you give yourself plenty of time, and wear gloves and goggles.

Begin by unscrewing all opening windows at the hinges and removing them. Then take away the beading and putty around any fixed panes and take them out too.

Once you’ve removed all the glass, use a saw to put angled cuts in the frame, and a bar and hammer to remove it in sections. You should remove the sill if you’re going to replace that too.

Finally, cut through any screws holding the frame into place with a hacksaw.
