How to Repair Double Glazed Windows
There are a few indicators that indicate your double-glazed windows require to be fixed. Draughts and water ingress are obvious signs of damage to the window frames. They must be fixed as quickly as possible.
Misting may also indicate that your window seals are damaged and in need of replacement. Replacing the seals will solve the issue and stop condensation, draughts, or leaks.
Broken Panes
Broken glass is among the most common problems that double-glazed windows face. While double pane windows are much harder to break than single pane windows however, accidents can occur and you'll need to repair a broken window as soon as you can.
The first step is to take out any glass fragments that are loose that remain in the frame. Wear eye protection and gloves while removing the glass as it can be very sharp. Be sure to check the floor for fragments that are not fixed after the shards are gone. It's also recommended to pull out any hooks made of metal that hold the panes together.
After the glass has been removed, you will have to remove the old glazing compound (small fasteners that fix the glass into the frame of the window), and replace them with new ones. It's a lengthy process that requires some tools. You will require latex glazing putty, metal glazing points, pliers heat gun and a putty blade.
It is recommended to start 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 paint or wood stuck to your tool. Also, if you end up removing a portion of the sash's wood, ensure that you employ a chisel or a utility knife instead of a chemical stripper, because this could cause damage.
When you're done, be sure to remove any wood that is not sanded to smooth it. Once it is smooth you can apply linseed oil or a clear wood sealer to safeguard it from water and future damage.
You can make a few quick fixes to fix a cracked double pane window. However, these methods won't fix the problem and should only be used as a temporary solution. A silicone caulk can help to seal the gap, but it's important to make sure that you choose a high-quality caulk and follow proper application methods.
Condensation
If you notice moisture or mist between your double glazing glass panes it means that the window seal isn't working. This could be a problem because it stops the gas or air that is used to insulate from being trapped between the two panes of glass, so it won't do its job correctly and this will lead to temperature changes that result in condensation forming.
Fortunately, this issue can be easily repaired by a double glazing expert. Your window contractor will remove both the window sash and window as well as the IGU (insulating unit) to fix the problem. Then the gasket is blown in to create an airtight seal and prevent condensation from occurring again. They'll also apply a specific drying agent to help dry the area and help stop the condensation from recurring.
There may be a fog between glass panes in double-glazed windows when the frame has changed over time. This can break the seal. This can be a huge problem, as your windows won't function effectively and lose energy efficiency.

Broken Locks & Handles
If the handle on your window is broken or difficult to open, it could be a major problem as it prevents you from using your windows. It also gives burglars an opportunity to break into your house. There are several options to address this issue but the most effective solution is to speak with an uPVC professional. They can repair the problem for you, or at the very least offer you a new handle.
There are many kinds of window locks, however, the most well-known is the Maco or Mila locks which are typically found on uPVC frames. These locks employ bayonet rods to lock and these are very easy to seize up. If this occurs, the handle's nase will be stuck in the out position and will not go back into the locked position wedged. This can be a very difficult issue, but it can be fixed by following a few steps.
To fix the issue, you'll need to take off the handle. This should be simple enough using the help of a screwdriver. After you have removed the handle, you'll be able to view the screws that secure the lock to the frame. After the screws have been removed and the handle is removed, you can use a wrench or pliers to attempt to grab the bolts for the shoot. If this fails then you can put the tool between the frame and the window (the gap could be different at each end of the windows) and then make an "u" shape with your fingers to grasp the bolts.
You can close your window by moving the handle back to its closed position if capable of removing the shoot bolts. But it won't be able to open again with the handle, as the gearbox (espag or espagnolette) will probably be faulty. You can refit the gearbox (espag or espagnolette) without the shoot bolts so that the window can still be opened using the handle.
Broken Hinges

After double glazing repairs 've removed the hinges and replaced them with plywood boards that are cut to the proper size. The plywood should be thicker than the original to support the weight when the window is closed and opened. Use wood filler to ensure that the hole left behind by the old hinge does not leak or become loose.
Once you've replaced hinges and filled the holes, you'll need paint them. Be sure to apply a high-quality paint to ensure it will last as long as it can. Once the paint has dried, you can reattach the window. Secure any screws that are loose.
Regular maintenance is also essential for hinges on windows. You can help them last longer by regularly cleaning the tracks of friction and lubricating the hinge mechanism.
