How to Repair Double Glazed Windows
There are a few distinct indications that your double glazed windows require repairs. Water ingress or draughts leaking through the frames are an obvious indication of window damage and must be fixed as soon as is possible.
Misting may also indicate that the window seals are in need of replacement. Replacing the window seals will solve the issue, and stop draughts, leaks, or condensation.
Broken Panes
One of the most common problems that a double-glazed window faces is broken glass. Double-pane windows are harder to break than single panes, however accidents can still happen. It is important to repair damaged glass as quickly as possible.
Remove any loose glass fragments that might remain in the frame. Don't forget to wear gloves and eye protection while doing this, as glass can be extremely sharp. Once the shards are removed, inspect the floor of your home for extra pieces of glass that may be left. Also, it's a good idea to search for any hooks made of metal that could be holding the panes together and pull these out also.
After the glass has been removed then you can begin the process of removing the old glazing compound and glazing points (small fasteners that fix the glass to the window frame) and replacing them with new ones. It's a lengthy process that requires some tools. This includes latex glazing putty; metal glazing points; pliers; a heat gun; and a putty knife.
When removing the old glaze compound and points It's a good idea to start at the top of the sash, and move down. This will help you avoid getting any of the sash's paint or wood stuck to the tool. If you're looking to remove a portion of the wood from the sash, use the utility knife or chisel instead of chemical strippers which could cause damage.
Finally, when you're finished ensure that you scrub any wood that's not finished to smooth it. When it's smooth, you can apply Linseed oil or a clear wood sealer to shield it from water and further damage.

These locks lock with rods that resemble bayonets, which could easily jam. 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 gruelling issue, but it can be fixed with a few easy steps.
To fix the issue you must first remove the handle, which is easy enough using a screwdriver. After you have removed the handle, you'll be able to view the screws that secure the lock to frame. After the screws have been removed, you may try to grab the bolts using an awl or a pair of pliers. If this doesn't work, you can insert the tool into the gap between the frame and the window (the gap may differ at the ends of the windows) and make an "u" shape using your hand to grab the bolts.

The gearbox (espag or espagnolette.) is probably faulty and won't open with the handle.

It is also recommended to use a wood filler to ensure that the hole created by the hinge is completely filled and will not leak or loosen in the future.
