How to Repair Double Glazed Windows

Broken Panes
One of the most frequent issues a double-glazed window face is broken glass. Although double-pane windows are more difficult to break than single-pane windows however, accidents can occur and you'll need to fix a broken window as quickly as possible.
Get rid of any glass fragments that may still be inside the frame. Wear gloves and eye protection when removing the glass, as it can be very sharp. Be sure to check the floor for loose pieces once the shards have been removed. Also, it's a good idea to look for any metal hooks that may be keeping the panes in place and take them out too.
Once the glass is removed, you will have to take off the old glazing compound (small fasteners that hold the glass to the window frame), and replace them with new ones. This is a time-consuming process and you will need a few tools to accomplish the task. You will need latex glazing putty and metal glazing points, pliers an electric heat gun, and a putty blade.
When you are removing the old glazing compound and points it is a good idea to start at the top of the sash and begin to work your way down. This will ensure that you don't end up getting any of the sash's paint or wood stuck to the tool. If you do end up removing a portion of the sash's wood be sure to use a chisel or utility knife instead of a chemical stripper since this could cause damage.

Condensation
If you notice moisture or mist between the glass panes of your double glazing it means that your window seal isn't working. This could be a significant issue since it prevents gas or air that acts as an insulation from getting trapped between the two panes.

Then a new gasket is blown in to form an airtight seal and prevent condensation from happening again. They'll also apply a specific drying agent to help dry the area and help stop the condensation from recurring.
The other reason why you may notice mist between the glass panes of windows that are double-glazed is that the framework has shifted over time, which causes cracks in the all-important seal. This can be a serious problem, as windows that are not functioning properly and lose their energy efficiency.

It could be a major issue if your window handle is damaged, or it is difficult to open. You will not be able use your windows. This also gives burglars an opportunity to break into your house. There are a variety of ways to fix it but the best option is to call a uPVC expert.

There are many different types of window locks, however the most well-known is the Maco or Mila lock that can be found on the majority uPVC frames. These locks utilize bayonet-style rods to lock and these can easily seize up. If this occurs, the handle's nose will be stuck in the popped out position, and cannot be returned to the locked position wedged. This could be a difficult issue, but it is able to be solved by following a few steps.
To fix
repairing double glazing windows must first take off the handle, which should be easy enough with the help of a screwdriver. Once the handle is removed, you should then be in a position to see the screws that hold the lock to the frame. After the screws have been removed and the handle is removed, you can use a wrench or pliers to attempt to grasp the bolts that hold the shoot. If this doesn't work then you can put the tool between the frame and the window (the gap could be different between the two windows) and create an "u" shape with your fingers to grasp the bolts.
You can shut your window by moving the handle to a closed position if you're able to free the shoot bolts. However, it won't open again with the handle because the gearbox (espag or espagnolette) will probably be faulty. It is possible to replace the gearbox without the shoot bolts so the window can be opened with the handle (and is still secure), but you will have to purchase an entirely new handle and gearbox.
Broken Hinges
If your uPVC window hinges are no working properly, you may need to repair or replace them. It could be because the window was opened too tightly or the hinge snapped. Or, they may have a problem. Fortunately the replacement of the hinge is easy and quick and there's no need to buy a new window and you can have your old windows repaired instead.
Remove the hinges. To do this, unscrew the screws that hold the frame to the hinges. Once you've removed the hinges you can replace them with plywood boards that are cut to the right size. Make sure that the plywood you choose to use is more robust than the original board to ensure it can support the weight of the window when it is closed and open. You'll also want to use a wood filler to ensure that the hole created by the hinge is filled to the brim and will not leak or loosen in the future.
After you've re-installed the hinges and filled the holes, you'll have to paint them. Make sure to apply a high-quality paint to ensure that it will last for as long as it can. When the paint is dry, you can re-attach the window and tighten any loose screws.
Regular maintenance is essential for hinges on windows. Cleaning the friction stay track and lubricating hinge mechanisms will help them last longer. You can also use a wood preservative to shield them from the elements, which will help to stop corrosion and keep them looking good for as long as possible.
