How to Repair Double Glazed Windows
There are a few telltale indicators that indicate that your double-glazed windows require repairs. Water ingress or draughts through the frames are a clear indication of window damage and must be fixed in the shortest time possible.
Misting may also indicate that your window seals are in need of replacement. Replacing the seals will solve the issue and stop condensation, draughts, or leaks.
Broken Panes
One of the most frequent problems with double-glazed windows is broken glass. Although double-pane windows are less likely to break than single pane windows however, accidents can occur and you'll need to repair a broken window as quickly as possible.
The first step to take is to take out any glass fragments that are loose that remain in the frame. Make sure to wear eye protection and gloves while doing this, since glass can be extremely sharp. Be sure to check the floor for loose pieces once the shards are gone. Also, it's an excellent idea to look for any hooks of metal that could be holding the panes in place and take them out as well.
Once the glass has been removed, you will have to take off the old glazing compound (small fasteners that fix the glass into the frame of the window), and replace them with new ones. It is a long process that requires a few tools. This includes latex glazing putty, metal glazing points, pliers, a heat gun and a putty knife.
When you are removing the old glazing compound and points It's recommended to begin at the top of the sash, and begin to work your way down. This will prevent getting any of the paint or sash's wood stuck to your tool. Also, if double glazing windows repairs end up removing some of the sash's wood ensure that you use a chisel or utility knife instead of a chemical stripper, because this could cause damage.
After that you can sand the wood. When the wood is smooth, you can seal it with clear or linseed wood sealer. This will protect it from water and further damage.
You can use some quick solutions to repair a cracked double pane window. However, these solutions will not repair the damage and should be used as a temporary solution. Use of silicone caulk will help seal the gap. However it is crucial to use a high-quality caulk and proper application techniques.
Condensation
If you notice a haze of moisture or mist between your double glazing glass panes it is a sign that the window seal isn't working. This could be a problem because it prevents the gas or air that is used to insulate from getting trapped between the two glass panes which means it cannot do its job properly and this will lead to temperature changes that cause condensation to form.
Fortunately, the issue can be easily repaired by an expert in double glazing. To fix the problem, your window contractor will remove the affected window sash and IGU (insulating glass unit) before blowing into a new gasket to make a strong and airtight seal to stop condensation from happening again. They will also employ a drying agent to help the area dry out and stop the condensation from occurring again.
You might also notice a fog between glass panes in double-glazed windows, if the frame has changed over time. This will crack the seal. This can be a problem because it means your windows won't function properly and lose their energy efficiency.

These locks are secured with rods in the form of bayonets that can easily jam. The handle's nose is stuck in the popped-out position, and it is unable to return to the wedged lock position. This can be a gruelling issue, but it can be resolved with just a few steps.
To fix the issue you'll need to take off the handle. This can be done easily enough with a screwdriver. After removing the handle, you will be able see the screws that hold the lock to frame. Once the screws are removed, you can make use of pliers or a wrench to attempt to grab the bolts for the shoot. If this fails, you can insert the tool into the gap between the frame and the window (the gap could be different at each end of the windows) and create an "u" shape with your fingers to grasp the bolts.
If you can manage to unblock the bolts for shooting, you can close the window by moving the handle to a closed position. The gearbox (espag or espagnolette.) is probably faulty and will not open when you pull the handle. It is possible to replace the gearbox (espag or espagnolette) without the shoot bolts so that the window will still be opened with the handle.
Broken Hinges

After the hinges are removed, you can replace the boards using plywood that has been cut to the right size. The plywood should be thicker than the original to support the weight when the window is opened and closed. You'll also want to use wood filler to ensure that the hole created by the hinge is completely filled and will not leak or loosen in the near future.
After you've filled holes and replaced the hinges, then you'll need to paint the doors. Make sure you apply a high-quality paint to ensure it lasts as long as possible. Once the paint has dried, you can attach the window again. Secure any loose screws.
