How to Repair Double Glazed Windows
There are some telltale signs your double-glazed windows require to be fixed. Water ingress or draughts through the frames are an obvious indication of damage to your windows and must be repaired as soon as is possible.

Broken Panes
One of the most frequent issues a double-glazed window face is broken glass. Double-pane windows are more difficult to break than single panes, yet accidents do occur. You will want to repair a damaged glass as quickly as you can.
The first step to take is to take out any glass shards that are not completely removed that are still in the frame. Make sure to wear eye protection and gloves while doing this, as glass can be extremely sharp. After the shards have been removed, look around the floor of your home for extra pieces of glass that may be left. Also, it's recommended to look for any metal hooks that could be holding the panes in place and remove them also.
Once the glass is removed then you can begin the process of removing the old glass compound and glazing points (small fasteners that pin the glass in the window frame) and replacing them with new ones. It's a lengthy process that requires the use of a few tools. This includes latex glazing putty, metal glazing points; pliers; heat gun; and a putty knife.
It is recommended to start at the top and work your way down as you remove the old points and glazing compound. This will prevent any paint or wood from the sash from adhering to your tool. If you need to remove some of the wood from the sash, use an utility knife or Chisel instead of chemical strippers which could cause damage.
When you're done, sand the bare wood. When the wood is smooth, you can seal it using linseed or clear wood sealer. This will protect it from water and further damage.

Broken Locks & Handles
If your window handle is damaged or difficult to open, it can be a major problem as it makes it impossible to use your windows. This could also give burglars the opportunity to gain entry into your home. There are several solutions to this problem, but the best option is to connect with a uPVC professional. Based on the severity of the issue they are able to usually fix it for you or at least provide you with a replacement handle.
There are a number of different kinds of window locks, however the most common is the Maco or Mila lock, which can be found on the majority of uPVC frames. These locks utilize bayonet-style rods to lock, and they are able to easily seize up. If this happens, the handle's nose is stuck in the popped out position and won't be able to return to the wedged locked position. This can be a annoying issue, but it is able to be solved with a few simple steps.
To resolve the issue, you will need to first take off the handle, which should be done with a screwdriver. After removing the handle you'll be able to view the screws that hold the lock to frame. After the screws have been removed, you can attempt to grab the bolts with the help of a wrench or a pair pliers. If this fails then you might need to insert the tool through the gap between the window and frame (the gap may be different at each end of the window) and create an "u" shape using your hands to attempt to grab the shoot bolts.
You can close your window by adjusting the handle to the closed position if able to free the shoot bolts. But it won't be able to be able to open again using the handle, as the gearbox (espag or espagnolette) is likely to be damaged. It is possible to replace the gearbox without the shoot bolts, so the window can be opened with the handle (and it will remain secure) However, you'll need to order the new handle and gearbox.
Broken Hinges

Remove the hinges. This is accomplished by removing 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 proper dimensions. The plywood should be thicker than the hinges that came with it to help support the weight when the window is closed and opened. Use wood filler to make sure the hole left behind by the old hinge will not leak or break.
After you've filled in the holes and put on the hinges, then you'll require painting the doors. Make sure you employ a top-quality paint to ensure it will last as long as possible. When the paint is dry, you can re-attach the window and tighten any loose screws.
Window hinges also require regular maintenance. Cleaning regularly the track of friction and lubricating the hinge mechanisms will make them last longer. You can also apply a wood preservative to shield them from the elements, which can help to stop rust and maintain their appearance for as long as possible.
