Repair Double Glazed Windows: The Good, The Bad, And The Ugly
How to Repair Double Glazed Windows
There are some telltale signs your double-glazed windows need to be fixed. Obviously, water ingress or draughts leaking through the frames are a clear indication of damage to your windows and will need to be fixed in the shortest time possible.
However, misting could be a sign that your window seals require replacing. Replacing the seals will solve the issue and will stop condensation, draughts, or leaks.
Broken Panes
One of the most common problems that a double-glazed window faces is broken glass. Double pane windows are less likely to break than single-pane ones however, accidents can happen and you will want to fix a broken window as quickly as possible.
The first step to take is to get rid of any loose shards of glass that remain in the frame. Don't forget to wear a pair of gloves and eye protection while doing this, since glass can be very sharp. Examine the floor for fragments that are not fixed after the shards are gone. It's also recommended to pull out any hooks that hold the panes together.
Once the glass has been removed, you'll need to remove the old glazing compound (small fasteners that fix the glass to the window frame), and replace them with new ones. This is a time-consuming procedure and requires some tools to complete the task. You will need latex glazing putty and metal glazing points, pliers a heatgun and a putty blade.
It's best to start at the top and work your way down when removing the old points and glazing compound. This will prevent any wood or paint that is removed that is left in the sash from sticking to your tool. If repairing double glazing do remove some of the sash's wood be sure to employ a chisel, or a utility knife instead of a chemical stripper, since this could cause damage.
After you've finished make sure you scrub any wood that's not finished to smooth it. When the wood is smooth, you can seal it with clear or linseed wood sealer. This will help protect it from water and further damage.
You can make a few quick fixes to fix cracks in a double-pane window. However, these solutions won't fix the problem and should only be used as a temporary solution. A silicone caulk can help to seal the gap, but you need to ensure that you choose a high-quality caulk and adhere to the correct application methods.
Condensation
If you've noticed any moisture or mist between the glass panes of your double glazing, it means that one of your windows has a broken seal. This can be a serious problem as it prevents the gas or air that is used to insulate being trapped between two panes.
Fortunately, this can be easily repaired by a double glazing expert. To resolve the issue the window repair professional will take out the affected window sash and IGU (insulating glass unit) before blowing into a new gasket to create a sturdy and airtight seal that will prevent condensation from happening again. They'll also use a special drying agent to help dry the area and stop the condensation from happening again.
You might also notice a mist between glass panes in double-glazed windows, when the frame has changed position over time. This could cause the seal to break. This could be a major issue as your windows will not work correctly and lose their energy efficiency.
It is possible to change a double-glazed window's glass, however, it can be costly and is typically only needed when the window is beyond repair. If you're experiencing problems with your double-glazed windows and are still within the warranty period, you might be able to get it repaired at no cost or for a reduced price.
It is worth checking the terms of your warranty before you contact the company to determine whether they can solve the problem without having to replace the entire window. Double-glazed windows usually have warranties of between 10 and 20 years. You may find that the company is able to fix the window unit instead of replacing it. If this is the case they'll likely send a professional to fix your double-glazed windows. They're able to complete the task quickly. This is a less expensive option than buying and installing brand new double glazed windows and is also better for the environment!
Broken Locks & Handles
If the handle on your window is damaged or difficult to open, it can be a huge issue as it hinders you from using your windows. This could also give burglars the opportunity to gain entry into your home. There are several ways to fix it however the most effective method is to call an uPVC expert. Depending on the severity of the issue they will usually be able to fix it for you or at the very least, provide you with an alternative handle.
There are many different kinds of window locks. However, the most well-known is the Maco or Mila lock that can be found on the majority of uPVC frames. They lock using bayonet-style rods, which can easily become jammed. If this occurs, the handle's nase will remain in the popped out position, and won't be able to return to the wedged locked position. This can be a gruelling problem, but can be fixed with a few easy steps.
To fix the issue, you'll need to take off the handle. This can be done easily enough with a screwdriver. After the handle is removed, you will be aware of the screws holding the lock to the frame. Once the screws are removed, you may try to grab the bolts using a wrench or pair of pliers. If this does not work then you can put the tool into the gap between the frame and the window (the gap could be different between the two windows) and create an "u" shape using your hands to grasp the bolts.
If you are able to free up the bolts for shooting, you can close the window by moving the handle into the closed position. The gearbox (espag or espagnolette.) is probably faulty and will not open when you pull the handle. You can replace the gearbox (espag or espagnolette) without the shoot bolts in order that the window will still be opened by the handle.
Broken Hinges
If your uPVC window hinges aren't longer operating smoothly it is possible to replace or repair them. It could be that the window was opened too forcefully, or that the hinge snapped. They could also have a flaw. It's simple to replace the hinge, which means you don't have to purchase new windows.
Remove the hinges. To do this, remove the screws that hold the frame to the hinges. Once the hinges have been removed, you can replace the boards using plywood that has been cut to the right 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 closed and opened. You'll also want to use a wood filler to ensure that the hole that was left by the hinge is filled completely and will not leak or break in the near future.
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 it can. Once the paint has dried and you are able to reattach the window. Tighten any screws that are loose.
Regular maintenance is also essential for window hinges. You can make them last longer by regularly cleaning the friction stay tracks and lubricating the hinge mechanism. You can also use wood preservatives to protect them against the elements. This will help prevent rusting and keep them looking great for as long as you possibly can.
