How to Repair Double Glazed Windows
There are several tell-tale signs that your double glazed windows require repair. Obviously, water ingress or draughts through the frames are an obvious indication of window damage and must be repaired as soon as possible.
Misting can also indicate that your window seals are damaged and in need of replacement. Replacing your window seals can solve the issue, and prevent leaks, draughts or condensation.
Broken Panes
One of the most common issues a double-glazed window face is broken glass. Although double-pane windows are more difficult to break than single pane windows, accidents do occur and you'll want to repair a broken window as quickly as possible.
The first step is to remove any loose shards of glass that are still in the frame. Make sure to wear eye protection and gloves while doing this, as glass can be extremely sharp. Examine the floor for fragments that are not fixed after the shards have been removed. It is also a good idea for you to remove any metal hooks holding the panes together.
Once the glass is removed, you will have to remove the old glazing compound (small fasteners which pin the glass in the frame of the window), and replace them with new ones. It's a lengthy procedure that requires some tools. These include latex glazing putty, metal glazing points, pliers, a heat gun; and a putty knife.
When removing the old glaze compound and points, it's a good idea to start at the top of the sash and move down. This will help you avoid getting any of the sash's paint or wood stuck to your tool. If you have to take off some of the wood from the sash, make use of a utility knife or a Chisel instead of chemical strippers which can cause damage.
When you're done, be sure to remove any wood that is not sanded to smooth it. Once the wood is smooth then you can seal it with clear wood sealer or linseed. This will shield it against water and future damage.
There are a few quick fixes to fix a cracked double pane window. However, these solutions are not a solution to repair the damage and should only serve as an interim solution. The use of a silicone caulk may aid in sealing the gap, but it is important to ensure that you use a high-quality caulk that is applied using the proper techniques.
Condensation
If you notice a haze of moisture or mist between the panes of glass that you have double glazing, this means that the window seal has failed. This can be a serious issue since it prevents gas or air that acts as an insulation from being trapped between two panes.
A double glazing expert can easily repair this problem. Your window contractor will remove both the window sash as well as the IGU (insulating unit) to correct the issue. Then the gasket will be blown in to form an airtight seal and prevent condensation from occurring again. They'll also use a special drying agent to help dry the area and prevent the condensation from happening again.
The other reason why you may see a haze between the glass panes of windows with double glazing is because the framework has shifted over time, which can break the crucial seal. This can be a major issue because it means your windows won't work correctly and will lose energy efficiency.
It is possible to replace double-glazed window's glass, but this can be expensive and is usually only required when the window is beyond repair. However, if you've discovered the signs of a problem with your double-glazed windows, and you're still within the warranty period, then it may be possible to get repaired for free or at a lesser cost.
Check your warranty terms before making contact with the company to determine whether they can fix the problem without having to replace the entire window. Double-glazed windows typically come with a guarantee of 10 to 20 years. You might find that the company is able to fix the window unit instead of replacing it. If this is the situation, they will likely send a specialist out to fix your double-glazed windows. They usually can do this quickly. This is a less expensive alternative to buying and installing new double-glazed windows. It's also better on the environment!
Broken Locks & Handles
It could be a major issue if your window handle is broken, or if it is difficult to open. You will not be able use your windows. This also gives burglars the chance to break into your house. There are a few solutions to address the issue, but the best way is to contact a uPVC expert. They can fix the issue for you, or provide you with a replacement handle.
There are many types of window lock, however, the most well-known is the Maco or Mila locks which are typically found on uPVC frames. These locks use bayonet style rods to lock, and they are able to easily seize up. If this happens, the handle's nose will be stuck in the out position and cannot be returned to the locked wedge. This can be a gruelling issue, but it can be fixed with a few easy steps.
To fix the issue you'll need to remove the handle. This should be simple enough with the help of a screwdriver. Once the handle is removed, you should then be in a position to see the screws that secure the lock to the frame. Once the screws have been removed, you may try to grab the bolts with the help of a wrench or a pair pliers. If this doesn't work, you can insert the tool between the frame and the window (the gap may differ between the two windows) and create an "u" shape with your hand to grab the bolts.
If you manage to free up the shoot bolts, then you can shut your window by adjusting the handle to a closed position. The gearbox (espag or espagnolette.) is likely to be damaged and won't open when you pull the handle. It is possible to replace the gearbox without the shoot bolts so the window can be opened with the handle (and is still secure) however, you'll require an entirely new handle and gearbox.

If your uPVC window hinges are no working properly it is possible to have them repaired or replaced. It could be that the window was opened too vigorously or the hinge snapped. Or, they may have a flaw. Luckily it is easy and quick and there's no need to purchase a new window instead, you can get your old windows repaired instead.
Remove the hinges. This is accomplished by removing the screws that secure 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 original to support the weight when the window is shut and opened. Use wood filler to ensure the hole left by the old hinge does not leak or become loose.
Once you've replaced hinges and filled the holes, you'll have to paint them. Use a good paint to make sure it lasts as long as possible. Once the paint is dry it is possible to reattach the window and tighten any loose screws.
Regular maintenance is also essential for hinges on windows. Cleaning the friction stay track and lubricating the hinge mechanisms will ensure they last longer. You can also use wood preservatives to protect them against the elements. This will stop corrosion and keep them looking good for as long as you can.
