How to Repair Double Glazed Windows
There are a few distinct indications that your double glazed windows require repairs. Water infiltration or draughts that enter the frames are a clear indication of window damage and must be fixed in the shortest time possible.
However, misting could be an indication that your window seals are in need of replacing. Replacing your window seals will solve the problem, and stop draughts, leaks, or condensation.
Broken Panes
Broken glass is among the most common problems that double-glazed windows face. Double-pane windows are more difficult to break than single panes, however accidents can happen. You will want to repair the damaged glass as quickly as possible.
Take out any glass fragments that could be inside the frame. Don't forget to wear gloves and eye protection when doing this, as glass can be sharp. Check the floor for any loose pieces once the shards have been removed. It's also a good idea for you to pull out any hooks made of metal that hold the panes together.
After the glass has been removed, you'll have to take off the old glazing compound (small fasteners that hold the glass in the window frame) and replace them with new ones. It is a long process that requires some tools. You will require latex glazing putty and metal glazing points, pliers a heatgun and a putty blade.
It is recommended to begin at the top and work your way downwards as you remove the old points and glazing compound. This will stop any wood or paint from the sash from sticking to your tool. Also, if you do end up removing a portion of the sash's wood make sure you employ a chisel, or a utility knife instead of a chemical stripper, as this can cause damage.
After that, sand the bare wood. Once the wood is smooth then you can seal it with clear wood sealer or linseed. This will protect it against water and future damage.
There are a few simple fixes to repair cracks in a double-pane window. But these fixes will not repair the damage and should only be used as a temporary solution. Utilizing silicone caulk will aid in sealing the gap. However, it is important to use caulk of high-quality and with proper application techniques.
Condensation
If you've noticed water or mist between the glass panes of your double glazing, it's a sign that one of your windows has a failed seal. This could be a problem because it blocks the insulating air or gas from getting trapped between the two panes of glass and therefore it can't perform its job correctly and this can cause temperature fluctuations that result in condensation forming.
Fortunately, this can be easily fixed by an expert in double glazing. To correct the issue the window repair professional will take off the affected window sash as well as the IGU (insulating glass unit) before blowing into a new gasket to create a strong and airtight seal to prevent condensation from occurring again. They'll also use a special drying agent to help dry out the area and stop the condensation from recurring.
You may also notice mist between glass panes in double-glazed windows if the frame has changed position over time. This could cause the seal to break. This can be a huge problem, as your windows will not work effectively and lose energy efficiency.
While it is possible to replace panes of a double-glazed window however, it can be extremely expensive and is typically only needed if there are severe issues with the window that is beyond repair. If you're experiencing problems with your double-glazed window but are still in the warranty period, you might be able repair it at no cost or for an affordable cost.

Broken Locks & Handles
It can be a big issue if your window handle is damaged or broken, or if it is difficult to open. You will not be able to use your windows. This also gives burglars the opportunity to break into your home. There are several solutions to address the issue but the best option is to speak with an uPVC expert. They can fix the issue for you, or give you a replacement handle.
There are many different types of window locks. However, the most popular is the Maco or Mila lock that is found on the majority of uPVC frames. 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 state, and it is unable to return to the wedged lock position. This could be a difficult issue, but it can be resolved with a few simple steps.
To fix the issue, you'll need to remove the handle. This can be done easily enough with the help of a screwdriver. After misted double glazing repairs have removed the handle, you'll be able to view the screws that hold the lock to the frame. After the screws have been removed, you can try to grab the bolts with the help of a wrench or a pair pliers. If this fails it is possible to insert the tool through the gap between the frame and window (the gap can be different at each end of the window) and create an "u" shape using your hands to try to grab the shoot bolts.
You can shut your window by adjusting the handle back to its closed position if able to free the bolts that shoot. The gearbox (espag or espagnolette.) is most likely damaged and won't open by the handle. It is possible to replace the gearbox without the shoot bolts which means that the window can be opened by the handle (and it will remain secure) However, you'll need to order the new handle and gearbox.
Broken Hinges
You may need to repair or replace your uPVC windows hinges if they are not functioning smoothly. Whether this is due to them having been opened with too much force the hinge snapping or dropping or they had a fault in the first place and it causes problems that make using your window difficult. It's easy to repair the hinge so you don't have to purchase new windows.
Remove the hinges. To do this, loosen the screws that attach the frame to the hinges. After you've removed the hinges, you can replace them with plywood boards that are cut to the correct size. The plywood should be more dense than the hinges that came with it to help support the weight of the window when it is shut and opened. Use wood filler to make sure the hole left by the hinge of the past does not leak or become loose.
After you've re-installed hinges and filled the holes, you'll have to paint them. Make sure you use a high-quality paint to make sure it lasts as long as possible. After the paint has dried, you can re-attach the window and tighten any loose screws.
Window hinges also require regular maintenance. You can help them last longer by cleaning them regularly on the tracks of friction and lubricating the hinge mechanism. You can also apply wood preservatives to shield them from the elements, which can help to keep them from corrosion and keep them looking great for as long as is possible.
