How to Repair Double Glazed Windows
There are some telltale signs your double-glazed windows need to be fixed. Water infiltration or draughts that enter the frames are a clear sign of damage to the window and should be fixed as soon as possible.
Misting may also indicate that your window seals are in need of replacement. Replacing the seals will fix the issue and stop condensation, draughts, or leaks.
Broken Panes
Broken glass is one of the most frequent issues that double-glazed windows confront. Although double-pane windows are much harder to break than single-pane windows, accidents do happen and you will want to repair a damaged window as soon as is possible.
Get rid of any glass fragments that might remain in the frame. Wear eye protection and gloves when removing the glass, because it is extremely sharp. Be sure to check the floor for loose pieces once the shards have been removed. It is also a good idea for you to remove any hooks that hold the panes together.
After the glass is removed, you can begin the process of removing the old compound and glazing points (small fasteners that secure the glass to the window frame) and replacing them with new ones. It is a long process that requires some tools. This includes latex glazing putty, metal glazing points; pliers; a heat gun; and a putty knife.
It is best to start at the top and work your way down in removing the old points and glazing compound. This will prevent getting any of the sash's wood or paint stuck to your tool. If you have to take off some of the wood from the sash employ the utility knife or Chisel instead of chemical strippers which can cause damage.
When you're done ensure that you remove any wood that is not sanded to smooth it. When the wood is smooth, you can seal it with linseed or clear wood sealer. This will shield it from future water damage.
There are a few easy fixes that you can try for a window that is cracked by a double-pane, but these methods will not repair the crack and should be used only as a temporary measure. A silicone caulk can aid in sealing the gap, but you need to make sure that you use a high-quality caulk that is applied using the proper methods.
Condensation
If you've noticed moisture or mist between the glass panes of your double-glazed windows, it's a sign that one of your windows has a broken seal. This could be a cause for concern because it prevents gas or the insulating air from being trapped between the two panes of glass, so it won't do its job effectively and will lead to temperature changes that result in condensation forming.
A double glazing specialist can easily repair this problem. The window company will take out both the window sash as well as the IGU (insulating unit) to address the issue. Then a new gasket will be blown in to create an airtight seal and prevent condensation from occurring in the future. They'll also use a special drying agent to aid in drying the area and stop the condensation from occurring again.
Another reason you might notice a misty appearance between the glass panes of a double-glazed window is that the framework has shifted over time, which breaks the all-important seal. This can be a huge problem, as your windows will not work effectively and lose energy efficiency.
Although it is possible to replace the panes of a double-glazed Window but this can be quite expensive and is normally only necessary when there are serious issues with a window that are beyond repair. However, if you've discovered the signs of a problem with your double-glazed windows and you're still within the warranty time, then it may be possible to get the issue fixed for free or at a reduced cost.
It's worth checking the terms of your warranty before you call the company to find out whether they can solve the issue without having to replace the entire window. Double-glazed windows usually have a guarantee of 10 to 20 years. You may find that the company can fix the window unit instead of replacing it. If this is the case, then they'll likely send a specialist out to fix your double glazed windows and will typically be in a position to complete the repair 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 can be a big issue if your window handle is damaged, or it is difficult to open. You will not be able to use your windows. It also gives burglars a chance to break into your home. There are a variety of solutions to address the issue but the best option is to speak with a uPVC expert. Based on the severity of the problem they are able to usually fix it for you, or at least provide you with a new handle.
There are several kinds of window locks, but the most popular is the Maco or Mila locks which are typically found on uPVC frames. These locks are secured with rods that resemble bayonets, which could easily become jammed. If this happens, the handle's nose is stuck in the popped out position, and won't be able to return to the wedged locked position. This can be a gruelling problem, but it can be resolved with just a few steps.
To fix the problem, you will need to first take off the handle, which is easy enough using the aid of a screwdriver. After removing the handle you'll be able to view the screws that hold the lock to frame. Once the screws are removed you can then make use of pliers or a wrench to try and grab the bolts for the shoot. If this doesn't work then you might need to insert the tool through the gap between the window and frame (the gap may differ on the opposite side of the window) and create an "u" shape with your hand to try to grab the shoot bolts.
If you can manage to remove the bolts for shooting, you can close your window by moving the handle to a closed position. But it won't be able to open again by the handle, since the gearbox (espag or espagnolette) will probably be faulty. You can refit the gearbox (espag or espagnolette) without the shoot bolts, so that the window will still be opened with the handle.
Broken Hinges
If your uPVC window hinges are no longer operating smoothly and smoothly, you might need to repair or replace them. It could be because the window was opened too tightly, or that the hinge snapped. They could also have a problem. Fortunately it is simple and quick and there's no need to buy windows from scratch - you can simply get your old windows repaired instead.
First, you'll need to remove the existing hinges. This is done by removing the screws that secure the hinges to the frame. After you've removed the hinges and replaced them with plywood boards that are cut to the right size. repairs to double glazing windows should be thicker than the original to support the weight of the window when it is closed and opened. You'll also want to use wood filler to ensure that the hole left by the old hinge is filled completely and will not leak or loosen in the near future.
Once you've replaced the hinges and filled in the holes, you'll need paint them. Use a good paint to ensure it lasts as long as is possible. Once the paint is dry, you can reattach the window. Tighten any screws that are loose.
Window hinges also require regular maintenance. You can ensure they last longer by regularly cleaning the track of friction and lubricating the hinge mechanism. You can also apply wood preservatives in order to shield them against the elements. This will prevent corrosion and ensure they look great for as long as you possibly can.
