How to Repair Double Glazed Windows
There are certain indicators that tell you your double-glazed windows must be repaired. Obviously, water infiltration or draughts that enter the frames are an obvious indication of window damage and must be fixed as soon as possible.

Broken Panes
One of the most common issues a double-glazed window face is broken glass. Double pane windows are much harder to break than single-pane windows However, accidents do occur and you'll need to fix a broken window as soon as is possible.
The first step is to remove any glass shards that are not completely removed that are still in the frame. Be sure to wear gloves and eye protection when doing this, as glass can be sharp. Check the floor for any fragments that have fallen off after the shards have been removed. It's also a good idea for you to pull out any hooks made of metal that hold the panes together.
Once the glass is removed, you can begin the process of removing the old glazing 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 some tools. These include latex glazing putty; metallic glazing points, pliers, a heat gun; and a putty knife.
It's best to begin at the top and work your way down in removing the old points and glazing compound. This will ensure that you don't end up getting any of the sash's wood or paint stuck to your tool. If you do end up removing a portion of the sash's wood be sure to employ a chisel or a utility knife instead of a chemical stripper because this could cause damage.
After you've finished, be sure to scrub any wood that's not finished to smooth it. Once the wood is smooth you can seal it with linseed or clear wood sealer. This will protect it from water and further damage.

Broken Locks & Handles
When your window handle is broken or difficult to open, it can be a major issue since it makes it impossible to use your windows. It also gives burglars the chance to break into your home. There are several solutions to address the issue however the most effective method is to call a uPVC expert. Based on the severity of the issue they are able to usually come and repair it for you or at a minimum, give you a new handle.
There are many kinds of window locks but the most popular is the Maco or Mila locks that are commonly found on uPVC frames. These locks use bayonet style rods to lock and these are able to easily seize up. The handle's nose is stuck in the popped-out position, and it is unable to return to the wedged locked position. This can be a frustrating 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 using the help of a screwdriver. After the handle is removed, you'll be aware of the screws that hold the lock to the frame. Once the screws have been removed, you can attempt to grab the bolts using the help of a wrench or a pair pliers. If this doesn't work it is possible to insert the tool through the gap between the frame and window (the gap may differ on the opposite side of the window) and create a "u" shape with your hand to try and grasp the bolts.
You can close your window by adjusting the handle to the closed position if in a position to release the shoot bolts. But, it will not open again by the handle, as the gearbox (espag or espagnolette) will probably be faulty. You can replace the gearbox (espag or espagnolette) without the shoot bolts in order that the window can be opened by the handle.
Broken Hinges
If your uPVC window hinges aren't working properly, you may need to replace or repair them. It could be that the window was opened too vigorously or the hinge snapped. Or, they may have a flaw. Thankfully, replacing the hinge is simple and quick and there's no need to buy windows that are new and you can have your old windows repaired instead.
The first step is to remove the hinges currently installed. To do this, remove the screws that attach the frame to the hinges. Once you've removed the hinges and replaced them with plywood boards that are cut to the proper dimensions. The plywood should be more dense than the original one to be able to withstand the weight of the window when it is opened and closed. It is also recommended to use wood filler to ensure that the hole that was left by the hinge is filled to the brim and will not leak or break in the future.
After you've filled in the holes and replaced the hinges, you will need to paint the doors. Be sure to use a high-quality paint to ensure it will last as long as is possible. Once the paint is dry it is possible to attach the window again. Make sure you tighten any screws that are loose.
Window hinges also require regular maintenance. Cleaning regularly the track of friction and lubricating hinge mechanisms will help them last longer. You can also apply wood preservatives to shield them from the elements, helping to keep them from corrosion and maintain their appearance for as long as possible.
