How to Repair Double Glazed Windows
There are certain indicators that tell you your double-glazed windows need to be repaired. Water infiltration or draughts that enter the frames are a clear indication of window damage and will need to be repaired as soon as possible.
However, misting may be a sign that your window seals need replacement. Replacing the seals can fix the issue and will stop condensation, draughts, or leaks.
Broken Panes
Broken glass is among the most frequent issues that double-glazed windows face. Double-pane windows are less difficult to break than single panes, yet accidents can still happen. It is important to repair the broken glass as soon as you can.
Get rid of any glass fragments that may still be inside the frame. Wear gloves and eye protection when removing the glass, because it could be extremely sharp. Be sure to check the floor for fragments that have fallen off after the shards are gone. It's also recommended to pull out any metal hooks holding the panes together.
After the glass has been 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's a lengthy process that requires a few tools. You will need latex glazing putty, metal glazing points, pliers, an electric heat gun, and a putty blade.
When removing the old glaze compound and points, it's best to start at the top of the sash, and work your way down. This will keep any wood or paint that is removed from the sash from sticking to the tool. Also, if you do end up removing some of the sash's wood ensure that you employ a chisel, or a utility knife instead of a chemical stripper, as this can cause damage.
After you've finished make sure you remove any wood that is not sanded to smooth it. Once it is smooth then you can apply linseed oil or a clear wood sealer to safeguard it from water and future damage.
There are a few quick fixes you can attempt for a cracked double-pane window, but these methods will not repair the crack and should only be used as a temporary solution. The use of a silicone caulk may help seal the gap, but it is important to make sure that you choose 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 it means that the window seal isn't working. This could be a cause for concern because it blocks the insulating air or gas from being trapped between the two panes of glass which means it cannot do its job effectively and can cause temperature fluctuations that result in condensation forming.
A double glazing expert can easily repair this problem. repairing double glazing windows will remove the window sash as well as the IGU (insulating unit) to correct the issue. Then the gasket will be blown into to create an airtight seal and prevent condensation from occurring again. They will also employ drying agents to aid in drying the area out and prevent the condensation from happening again.
You may also notice the glass panes are a little cloudy in double-glazed windows in the event that the frame has changed position over time. This will crack the seal. This can be a major issue because it means your windows won't work correctly and will lose their energy efficiency.
It is possible to replace a double-glazed window's glass, however, this can be costly and is typically only needed when the window is beyond repair. If you've noticed an issue with your double-glazed windows, and you're 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 reduced cost.
It's worth checking the terms of your warranty before you contact the company to see whether they are able to resolve the issue without having to replace the entire window. Double-glazed windows typically have an assurance of 10 to 20 years. It is possible that the company is able to repair the window instead of replacing it. If this is the case, they'll likely send a specialist out to repair your double glazed windows and will typically be able to do so quickly. This is a less expensive alternative than purchasing and installing brand new double-glazed windows, and it's more sustainable for the environment as well!
Broken Locks & Handles
When your window handle is damaged or difficult to open, it can be a major issue since it makes it impossible to use your windows. It can also give burglars an opportunity to gain entry into your home. There are several options to fix it but the best option is to contact a uPVC expert. They can repair the problem for you, or offer you a new handle.
There are a number of different types of window locks. However, the most popular is the Maco or Mila lock, which can be found on the majority of uPVC frames. These locks are secured with rods in the form of bayonets that can easily jam. If this occurs, the handle's nose is stuck in the popped out position and will not go back into the locked position wedged. This could be a frustrating issue, but it can be resolved by following a few easy steps.
To fix the problem, you will need to first take off the handle, which is easy enough using the aid of a screwdriver. Once the handle is removed, you will be aware of the screws holding the lock to the frame. Once the screws are removed, you can attempt to grab the bolts using an awl or a pair of pliers. If this doesn't work then you can put the tool into the gap between the frame and the window (the gap may differ between the two windows) and make an "u" shape with your fingers to grasp the bolts.
If you can manage to unblock the shoot bolts, then you can close the window by adjusting the handle into the closed position. But it won't be able to be able to open again using the handle, as the gearbox (espag or espagnolette) is most likely to be defective. You can refit the gearbox (espag or espagnolette) without the shoot bolts so that the window will still be opened using the handle.
Broken Hinges
You may need to repair or replace your uPVC windows hinges if they aren't operating properly. It could be that the window was opened too forcefully, or that the hinge snapped. They could also have a flaw. Luckily it is quick and easy and doesn't require you to buy windows from scratch instead, you can get your old windows repaired instead.
Take off the hinges. To do this, remove the screws that attach the frame to the hinges. After the hinges are removed, you can replace the boards using plywood that has been cut to the right size. The plywood should be more dense than the original one to be able to withstand the weight when the window is opened and closed. You'll also need to use a wood filler to ensure that the hole created by the hinge is filled completely and won't leak or become loose in the future.
After you've filled holes and replaced the hinges, then you'll need to paint the doors. Use a quality paint to ensure that it lasts as long as possible. Once the paint has dried it is possible to reconnect the window. Secure any screws that are loose.
Regular maintenance is also important for hinges on windows. You can make them last longer by cleaning them regularly on the track of friction and lubricating the hinge mechanism. You can also apply a wood preservative to protect them from the elements, which will help to keep them from corrosion and maintain their appearance for as long as possible.
