Broken Panes
Broken glass is among the most common problems that double-glazed windows have to face. Double-pane windows are harder to break than single panes, however accidents do occur. It is important to repair a damaged glass as quickly as you can.
Get rid of any glass fragments that might be inside the frame. Be sure to wear a pair of gloves and eye protection when doing this, as glass can be extremely sharp. Be sure to check the floor for fragments that have fallen off after the shards are gone. It's also recommended to pull out any hooks made of metal that hold the panes together.
After the glass has been removed, you can begin the process of removing the old glazing compound and glazing points (small fasteners that fix the glass into the frame of the window) and replacing them with new ones. It's a lengthy procedure that requires some tools. This includes latex glazing putty, metal glazing points, pliers, a heat gun and a putty knife.
It is best to begin at the top and work your way downwards in removing the old points and glazing compound. This will prevent any wood or paint that is removed from the sash from sticking to your tool. If you do end up removing a portion of the sash's wooden pieces, ensure that you employ a chisel, or a utility knife instead of a chemical stripper as this can cause damage.
When you're done you can sand the wood. Once the wood is smooth you can seal it with clear or linseed wood sealer. This will help protect it from future water damage.
You can make a few simple fixes to repair cracked double pane windows. However, these solutions will not repair the damage and should only serve as an interim solution.

Broken Locks & Handles
When your window handle is broken or hard to open, it could be a major issue since it hinders you from using your windows. It could also give burglars the chance to gain entry into your home. There are several options to address this issue, but the best option is to connect with an uPVC professional.

There are a number of different types of window locks, however the most common is the Maco or Mila lock that can be found on the majority of uPVC frames. These locks use bayonet style rods to lock and these can easily seize up. If this occurs, the handle's nase is stuck in the popped out position and won't be able to return to the wedged locked position. double glazing repairs can be a very frustrating issue, but it can be solved by following a few steps.
To fix the issue you'll need to remove the handle. This should be simple enough with a screwdriver. After removing the handle you'll be able to view the screws that hold the lock to frame. Once the screws have been removed you can then employ pliers or a wrench to try and grasp the bolts that hold the shoot. If this doesn't work it is possible to insert the tool through the gap between the frame and the window (the gap can be different at each end of the window) and make a "u" shape with your hands to try to grab the shoot bolts.
If you manage to remove the bolts that shoot, then you can close your window by adjusting the handle to a closed position. But it won't be able to open again by the handle because the gearbox (espag or espagnolette) will probably be faulty. It is possible to replace the gearbox without the shoot bolts, which means that the window can be opened using the handle (and will still be secure), but you will need to order the new handle and gearbox.

After the hinges have been removed you can replace the boards with plywood that has been cut to the correct size. The plywood should be more dense than the original to support the weight of the window when it is opened and closed. Use wood filler to ensure that the hole left by the hinge of the past does not leak or loosen.
After you've filled in the holes and put on hinges, you'll have to paint the doors. Use a quality paint to ensure it lasts as long as it can. After the paint has dried and you are able to reconnect the window. Make sure you tighten any loose screws.
Window hinges also require regular maintenance. Cleaning regularly the track of friction and lubricating hinge mechanisms will help them last longer.
