How to Repair Double Glazed Windows
There are several tell-tale indications that your double glazed windows require repair. Obviously, water ingress or draughts through the frames are an obvious indication of damage to your windows and must be repaired in the shortest time possible.

Broken Panes

Take out any glass fragments that could be in the frame. Wear gloves and eye protection while removing the glass because it could be extremely sharp. Check the floor for any fragments that are not fixed after the shards have been removed. Also, it is an excellent idea to search for any hooks of metal that could be holding the panes together and remove them too.
After the glass is removed, you can begin the process of removing the old compound and glazing points (small fasteners that secure the glass in the window frame) and replacing them with new ones. This can be a lengthy procedure and requires some tools to accomplish the task. This includes latex glazing putty; metal glazing points; pliers; a heat gun, and a putty knife.
When you are removing the old glazing compound and points It's recommended to begin at the top of the sash, and work your way down. This will stop any wood or paint that is left in the sash from sticking to the tool. If you're looking to remove some of the wood from the sash, use an utility knife or chisel instead of chemical strippers, which could cause damage.
After you're done you can sand the wood. When the wood is smooth then you can seal it using clear or linseed wood sealer. This will shield it against water and future damage.
You can make a few simple solutions to repair a cracked double pane window. However, these solutions won't fix the problem and should only serve as a temporary solution. The use of silicone caulk can help seal the gap. However it is essential to use a high-quality caulk and proper application methods.
Condensation
If you've noticed any moisture or mist between the glass panes of your double glazing, it's a sign that one of your windows is suffering from a failing seal. This could be a problem because it blocks the insulating air or gas from being trapped between the two glass panes which means it cannot do its job correctly and this can lead to temperature changes that cause condensation to form.

Then, a new gasket is blown in to create an airtight seal, preventing condensation from occurring again. They will also employ a drying agent to help the area dry out and stop the condensation from recurring.
Another reason you might notice a misty appearance between the glass panes of windows that are double-glazed is that the framework has moved slightly over time, which can break the crucial seal. This can be a huge issue as windows that are not functioning properly and lose their energy efficiency.

Broken Locks & Handles
If your window handle is damaged or difficult to open, it can be a major issue since it makes it impossible to use your windows. This could also give burglars an opportunity to break into your house. There are a few solutions to address the issue, but the best way is to contact an uPVC expert. Based on the severity of the issue they will usually be able to fix it for you, or at a minimum, give you a replacement handle.
There are a number of different kinds of window locks, however the most popular is the Maco or Mila lock that is found on the majority of uPVC frames. They lock using rods that resemble bayonets, which could easily jam. The handle's nose is stuck in the popped-out state, and it is unable to return to its wedged locked position. This can be a gruelling problem, but it can be resolved with just a few steps.
To fix the issue you'll need to remove the handle. This can be done easily enough with the help of a screwdriver. After the handle is removed, you should then be in a position to see the screws holding the lock to the frame. After the screws have been removed, you can attempt to grab the bolts with a wrench or pair of pliers. If this fails then you might need to insert the tool into the gap between the frame and window (the gap may differ on the opposite side of the window) and then make an "u" shape with your hand to try to grab the shoot bolts.
You can close your window by adjusting the handle to a closed position if you're able to free the bolts for shooting. But it won't be able to open again by the handle, since the gearbox (espag or espagnolette) will probably be faulty. It is possible to replace the gearbox (espag or espagnolette) without the shoot bolts so that the window can be opened with the handle.
Broken Hinges
If your uPVC window hinges aren't working properly it is possible to repair or replace them. If this is because of them being opened with too much force, the hinge snapping and dropping or they were defective to begin with and it causes problems that make using your window difficult. It's simple to replace the hinge, so you don't need to purchase new windows.
First, you'll need to remove the existing hinges. This is done by unscrewing the screws that hold the hinges to the frame. After you've removed your hinges, you can replace them with plywood boards cut to the right size. Make sure the plywood is more robust than the original board to ensure it can support the weight of the window when shut and open. Use wood filler to ensure that the hole left behind by the old hinge does not leak or break.
After you've filled holes and replaced the hinges, you will need to paint the doors. Be sure to apply a high-quality paint to ensure it will last for as long as it can. After the paint has dried, you can re-attach the window and tighten any loose screws.
Regular maintenance is essential for hinges on windows. Cleaning regularly the friction stay track and lubricating hinge mechanisms will help them last longer. You can also use wood preservatives to shield them from the elements, which will help to stop rust and keep them looking good for as long as is possible.
