How to Repair Double Glazed Windows
There are some telltale signs your double-glazed windows require to be repaired. Evidently, repairing double glazing windows or draughts that enter the frames are a clear indication of damage to your windows and must be fixed as soon as is possible.
However, misting may be a sign that your window seals require replacing. Replacing the seals can fix the problem and prevent condensation, draughts, or leaks.
Broken Panes
One of the most common problems with double-glazed windows is broken glass. While double pane windows are less likely to break than single-pane ones, accidents do occur and you'll need to fix a broken window as soon as you can.
Remove any loose glass fragments that could remain in the frame. Don't forget to wear eye protection and gloves while doing this, since glass can be sharp. Be sure to check the floor for fragments that have fallen off after the shards have been removed. It's also a good idea for you to remove any metal hooks holding the panes together.
After the glass is removed, you can begin the process of removing the old compound and glazing points (small fasteners that fix the glass into the window frame) and replacing them with new ones. It is a long process that requires some tools. You will require latex glazing putty, metal glazing points, pliers, a heatgun and a putty blade.
When you are removing the old glazing compound and points it is a good idea to start at the top of the sash, and work your way down. This will ensure that you don't end up getting any of the sash's paint or wood stuck to your tool. If you have to remove a portion of the wood from the sash make use of the utility knife or chipper instead of chemical strippers which can cause damage.
Finally, when you're finished ensure that you scrub any wood that's not finished to smooth it. Once the wood is smooth you can seal it using clear or linseed wood sealer. This will protect it against water and future damage.
There are a few quick solutions you can try to repair a damaged double-pane window However, these solutions will not repair the crack and should be used only as a temporary fix. Using a silicone caulk can help seal the gap, but it's important to ensure that you use a high-quality caulk and follow proper application techniques.
Condensation
If you notice a haze of moisture or mist between the panes of glass that you have double glazing, this means that your window seal isn't working. This can be a problem because it prevents the gas or air that is used to insulate from being trapped between the two glass panes and therefore it can't perform its job properly and this will lead to temperature changes that cause condensation to form.
A double glazing expert can easily repair this problem. To resolve the issue the window repair professional will take out the affected window sash and IGU (insulating glass unit) before putting in a new gasket to make a strong and airtight seal that will prevent condensation from occurring again. They'll also apply a specific drying agent to help dry out the area and help stop the condensation from recurring.
Another reason you may notice mist between the glass panes of windows that are double-glazed is that the framework has moved slightly over time, which causes cracks in the crucial seal. This could be a problem since it means that your windows will not function correctly and will lose their energy efficiency.
It is possible to change a double-glazed window's glass, but this can be expensive and is usually only necessary if the window is beyond repair. If you are experiencing issues with your double-glazed window and are still within the warranty period then you may be able to repair it at no cost or for an affordable cost.
It's worth checking the terms of your warranty before you contact the company to determine whether they can resolve the issue without having to replace the entire window. Double-glazed windows are usually covered by warranties of between 10 and 20 years, so you might find that they are able to repair faulty window units rather than replacing them completely. If this is the case, then they'll likely send a specialist to fix your double glazed windows and will typically be in a position to complete the repair quickly. This is a cheaper alternative to purchasing and installing new double-glazed windows. It's also better for the environment!
Broken Locks & Handles
If the handle on your window is broken or hard to open, it can be a huge issue as it makes it impossible to use your windows. It also gives burglars the chance to break into your home. There are several ways to fix it however the most effective method is to call a uPVC expert. They can fix the issue for you, or at least provide you with a replacement handle.
There are many different kinds of window locks, however the most common is the Maco or Mila lock, which can be found on the majority of uPVC frames. They lock using rods that resemble bayonets, which could easily become jammed. If this occurs, the handle's nose is stuck in the popped out position, and will not go back into the locked wedge. This can be a difficult problem, but it can be solved by following a few easy steps.
To resolve the issue, you'll have to remove the handle. This should be simple enough using a screwdriver. After removing the handle you will be able see the screws that attach the lock to the frame. Once the screws are removed, you may try to grab the bolts using the help of a wrench or a pair pliers. If this fails then you can place the tool into the gap between the frame and the window (the gap may differ between the two windows) and create an "u" shape with your hands to grasp the bolts.
If you can manage to unblock the bolts for shooting, you can close the window by moving the handle to the closed position. But, it will not open again by the handle because the gearbox (espag or espagnolette) is likely to be damaged. You can refit the gearbox (espag or espagnolette) without the shoot bolts in order that the window will still be opened using the handle.
Broken Hinges
If your uPVC window hinges aren't working properly and smoothly, you might need to repair or replace them. If this is because of the hinges being opened with too much force, the hinge snapping and dropping or they were defective at the beginning the issue could cause issues that make using your window difficult. It's simple to replace the hinge, so you don't have to purchase new windows.
The first step is to remove the hinges currently installed. This is done by unscrewing the screws that hold the hinges to the frame. 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 one to be able to withstand the weight of the window when it is opened and closed. You'll also want to use wood filler to ensure that the hole created by the hinge is filled to the brim and will not leak or loosen in the future.
After you've filled in the holes and replaced the hinges, then you'll have to paint the doors. Make sure you use a high-quality paint to ensure that it lasts as long as it can. After the paint has dried it is possible to reattach the window and tighten any loose screws.
Window hinges also require regular maintenance. Cleaning regularly the friction stay track and lubricating hinge mechanisms will make them last longer. You can also use wood preservatives in order to shield them against the elements. This will stop corrosion and keep them looking good for as long as you can.
