When changing your house's windows you don't necessarily need to complete the whole building. From time to time you may only need to have a single window replaced, possibly because of a broken pane or for upgrading to double glazing.
It's common for many people to replace simply one double glazed window. One factor that lots of people want to change one window is that the closed device inside has failed. You'll know if this has actually occurred because you'll have the ability to see condensation on the within glass, which obtains irritating because you can't clean it away. In this instance, you can pick to just change the covered unit or the entire structure, which you may wish to do if it's looking past its best.
When you're replacing just one double glazed window, if you know the brand name of your present windows you might ask your installer if they can source the very same ones. This will certainly help to maintain them looking as comparable as possible, although if your existing windows are older you may observe some discolouration on the outside compared to the new one, and locks and also flow vents could look various.
Changing just one double glazed window should not take a certified window fitter long, and also can cost as little as ₤ 300. It's worth remembering that all substitute windows require to be certified that they have actually been installed to fulfill building regulations, so you'll need to apply to your local building control officer who will certainly come as well as check the job then release a certification. If you ask an installer that is signed up with a self-certification scheme (like FENSA, CERTAS) to fit the window for you, they can issue the certificate themselves when they've completed the work.

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.
Unfortunately, you can’t fix the glass on one side of a double glazed window. That’s because they’re sealed units – once one pane of glass is broken, that will break the seal and its thermal insulation properties will be lost.
The good news is that if your window frame is still looking great, there’s no need to replace that. You can simply replace the glass in the window, which will cost much less. You can look to spend around £250 on a sealed unit, whereas a whole replacement single window may cost up to £600.
When an installer comes to replace the glass in your double glazed window, they will survey the inside and outside of your home around the window, then move any furniture by the window so they’ve got access. They should then pop a dust sheet down to stop any debris from getting on your floor.
Then, the installer will carefully remove the beads from the frame. They will then lift the glass out of the frame and put it somewhere safe before cleaning out all of the dust and any debris that has found its way into the frame. Using spacers at the bottom of the frame, the installer will make sure that the sealed unit is square in the frame to get a good fit. Once they’re happy, they will replace the beading and make sure it looks perfect before cleaning up their tools.
You could have a go at replacing the glass on a double glazed window yourself, but it’s not recommended. Leave it to the professionals who will know exactly what to do and will be able to do it quickly and safely.
