Once the shards have been removed, check the floor of your home for any additional loose pieces. It is also a good idea to search for any metal hooks that could be keeping the panes in place and remove them also.

This can be a lengthy procedure, and you'll need several tools to get the job done. These include latex glazing putty; metal glazing points; pliers; heat gun; and a putty knife.

If you have to remove some of the wood from the sash, employ an utility knife or Chisel instead of chemical strippers which could cause damage.

There are many different types of window locks, however the most well-known is the Maco or Mila lock that is found on the majority uPVC frames. They lock using rods that resemble bayonets, which could easily become jammed. If this occurs, the handle's nase will be stuck in the popped out position and will not go back into the wedged locked position. This can be a frustrating problem, but it can be fixed with just a few steps.
To fix the issue, you'll have to remove the handle. This is simple enough with the help of a screwdriver. After double glazing repairers have removed the handle, you will be able see the screws that hold the lock to frame. After the screws have been removed, you can attempt to grab the bolts with 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 create an "u" shape using your hand to grab the bolts.
If you manage to remove the bolts that shoot, then you can close the window by adjusting the handle into the closed position. The gearbox (espag, espagnolette, etc.) is likely to be damaged and will not open with the handle. You can replace the gearbox (espag or espagnolette) without the shoot bolts, so that the window will still be opened by the handle.

The first step is to take off the hinges that are currently in place. To do this, loosen the screws that hold the frame to the hinges. After the hinges have been removed you can replace the boards with plywood that has been cut to the correct size. Make sure that the plywood is larger than the original one so that it can withstand the weight of the window when open and closed. You'll also want to use a wood filler to ensure that the hole that was left by the hinge is filled to the brim and will not leak or loosen in the future.
After you've filled holes and replaced the hinges, you will require painting the doors. Make sure you use a high-quality paint to make sure it lasts 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. You can ensure they last longer by cleaning them regularly on the friction stay tracks and lubricating the hinge mechanism.
