How to Repair Double Glazed Windows
There are a few telltale indicators that indicate that your double-glazed windows need repair. Draughts and water ingress are obvious indicators of damage to frames of the windows. They should be repaired in the shortest time possible.
Misting can also indicate that your window seals are in need of replacement. Replacing the seals can fix the problem and prevent condensation, draughts, or leaks.
Broken Panes
Broken glass is one of the most frequent problems that double-glazed windows have to face. Double-pane windows are more difficult to break than single panes, but accidents can still happen. It is important to repair damaged glass as quickly as possible.
Take out any glass fragments that could be in the frame. Wear eye protection and gloves while removing the glass because it could be extremely sharp. After the shards have been removed, inspect the floor of your home for any other pieces that are loose. It is also an excellent idea to look for any hooks made of metal that could be holding the panes together and pull these out too.
After the glass is removed then you can begin the process of removing the old glass compound and glazing points (small fasteners that fix the glass into the window frame) and replacing them with new ones. This can be a lengthy procedure, and you'll need a few tools to complete the task. You'll need latex glazing putty, metal glazing points, pliers heat gun and a putty blade.
It's best to begin at the top and work your way downwards as you remove the old points and glazing compound. This will keep any wood or paint that is removed from the sash from sticking to the tool. If you need to remove some of the wood from the sash, employ an utility knife or Chisel instead of chemical strippers, which could cause damage.
When you're done make sure you sand any bare wood to smooth it. Once double glazing repairs can apply linseed oil or a clear wood sealer to safeguard it from water and future damage.
You can use some quick fixes to fix cracks in a double-pane window. But these fixes will not repair the damage and should only be used as a temporary solution. Using a silicone caulk can help to seal the gap, but it's important to make sure that you use a high-quality caulk and adhere to the correct application techniques.
Condensation
If you notice moisture or mist between the panes of glass that you have double glazing it means that your window seal has failed. This can be a problem because it prevents gas or the insulating air from being trapped between the two glass panes and therefore it can't perform its job properly and this can cause temperature fluctuations that cause condensation to form.
A double glazing specialist can easily fix this issue. To fix the problem, your window contractor will take off the affected window sash as well as the IGU (insulating glass unit) before putting in a new gasket. This will create a strong and airtight seal to prevent condensation from occurring again. They will also apply a drying agent to aid in drying the area out and prevent the condensation from occurring again.
Another reason you might notice a misty appearance between the glass panes of windows that are double-glazed is that the framework has moved slightly over time, which breaks the crucial seal. This can be a major issue since it means that your windows won't work correctly and will lose energy efficiency.
It is possible to change a double-glazed window's panes, however, this can be costly and is usually only necessary when the window is beyond repair. However, if you've discovered the signs of a problem with your double-glazed windows and are still within the warranty period and the window is still in good condition, it might be possible to have it fixed for free or at least at a lower cost.
Review your warranty's terms prior to contacting the company to determine if they can resolve the problem without replacing the entire window. Double-glazed windows typically have warranties of between 10 and 20 years. You may find that the company can fix the window unit instead of replacing it. If this is the case, they'll likely send a specialist to fix your double glazed windows and will typically be able to do so quickly. This is a cheaper alternative to purchasing and installing new double-glazed windows. It's also better on the environment!
Broken Locks & Handles
It can be a big issue if the handle of your window is damaged or broken, or if it is difficult to open. You won't be able to use your windows. This could also give burglars an opportunity to break into your home. There are several options to fix it however the most effective method is to call an uPVC expert. They will be able to fix the issue for you, or at the very least provide you with a replacement handle.
There are many different types of window locks, but the most popular is the Maco or Mila lock, which can be found on the majority of uPVC frames. These locks use bayonet style rods to lock and these can easily seize up. The handle's nose is stuck in the popped-out state, and it is unable to return to the wedged locked position. This can be a gruelling issue, but it can be resolved with just a few steps.
To fix the issue, you will need to first remove the handle. This is easy enough using the aid of a screwdriver. Once the handle is removed, you'll be in a position to see the screws that secure the lock to the frame. Once the screws have been removed, you can employ pliers or a wrench to try and grasp the bolts that hold the shoot. If this fails it is possible to insert the tool through the gap between the window and frame (the gap can be different at each end of the window) and create a "u" shape using your hands to attempt to grab the shoot bolts.
You can shut your window by moving the handle to the closed position if you're in a position to release the bolts for shooting. The gearbox (espag, espagnolette, etc.) is likely to be damaged and won't open when you pull the handle. You can refit the gearbox (espag or espagnolette) without the shoot bolts, so that the window can still be opened with the handle.
Broken Hinges
It could be necessary to repair or replace your uPVC windows hinges if they aren't functioning smoothly. It could be due to the hinges being opened by too much force, the hinge snapping or dropping or if they were defective in the first place the issue could cause issues that make using your window difficult. It's easy to replace the hinge, which means you don't have to buy new windows.
First, you'll need to take off the hinges that are currently in place. To do this, loosen the screws that hold the frame to the hinges. After you've removed your hinges and replaced them with plywood boards that are cut to the correct dimensions. The plywood should be thicker than the original one to be able to withstand 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 loosen.
After you've filled holes and replaced hinges, you'll have to paint the doors. Make sure you use a high-quality paint to ensure that it lasts as long as possible. Once the paint is dry, you can reconnect the window. Secure any screws that are loose.
Regular maintenance is also important for hinges on windows. You can help them last longer by regularly cleaning the track of friction and lubricating the hinge mechanism. You can also apply a wood preservative to protect them from the elements, which can help to prevent corrosion and keep them looking great for as long as you can.
