Also, it is a good idea to search for any hooks made of metal that might be keeping the panes in place and remove them as well.
After the glass has been removed, you'll have to take off the old glazing compound (small fasteners that hold the glass in the frame of the window) and replace them with new ones. It is a long-winded process and you will need several tools to accomplish the task. This includes latex glazing putty; metallic glazing points; pliers; a heat gun; and a putty knife.
When removing the old glaze compound and points It's best to start at the top of the sash, and work your way down. double glazing windows repairs will keep any wood or paint that is removed from the sash from sticking to the tool.

Broken Locks & Handles
It could be a major issue if the handle of your window is broken, or if it is difficult to open. You will not be able to use your windows. It also gives burglars a chance to break into your home. There are several options to address this issue however the most effective option is to connect with a uPVC professional.

There are a number of different types of window locks, however the most common is the Maco or Mila lock that is found on the majority uPVC frames. These locks employ bayonet rods for locking and are very easy to seize up. The handle's nose is stuck in the popped-out state, and it will not return to its wedged locked position. This can be a frustrating problem, but it can be solved with a few easy steps.
To fix the issue, you'll need to take off the handle. This is simple enough with a screwdriver. After you have removed the handle, you'll be able to see the screws that attach the lock to frame. Once the screws have been removed, you may try to grab the bolts using a wrench or pair of pliers. If this fails then you might need 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 hands to attempt to grab the shoot bolts.
You can shut your window by moving the handle back to its closed position if you're able to free the bolts for shooting. The gearbox (espag or espagnolette.) is likely to be damaged and won't open with the handle. It is possible to repair the gearbox without the shoot bolts, so the window can be opened using the handle (and it will remain secure), but you will require an entirely new handle and gearbox.
Broken Hinges
You may need to repair or replace your uPVC windows hinges if they aren't functioning smoothly.

It's easy to fix the hinge, so you don't need to buy new windows.
Remove the hinges. This is done by unscrewing the screws that attach the hinges to the frame. After the hinges are removed then you can replace the boards using plywood that has been cut to the correct size. The plywood should be thicker than the hinges that came with it to help 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 will not leak or loosen.
After you've replaced the hinges and filled in the holes, you'll need to paint them. Use a quality paint to make sure it lasts as long as it can. When the paint is dry, you can re-attach the window and tighten any loose screws.
Window hinges also require regular maintenance. You can make them last longer by regularly cleaning the friction stay tracks and lubricating the hinge mechanism. You can also apply wood preservatives to shield them against the elements. This will prevent corrosion and keep them looking great for the longest time you can.
