How to Repair Double Glazed Windows

There are some telltale signs your double-glazed windows require to be fixed. Draughts and water ingress are obvious signs of damage to the frames of the windows. They should be repaired in the shortest time possible.

However, misting could be a sign that your window seals are in need of replacing. Replacing the seals will fix the issue and 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 harder to break than single panes, but accidents can still occur. You will want to repair damaged glass as quickly as possible.

Get rid of any glass fragments that might remain in the frame. Make sure to wear gloves and eye protection when doing this, as glass can be sharp. Once the shards are removed, inspect the floor of your home for additional loose pieces. It is also a good idea for you to pull out any hooks made of metal that hold the panes together.

Once the glass has been removed, you'll have to remove the old glazing compound (small fasteners which pin the glass into the frame of the window), and replace them with new ones. It's a lengthy process that requires some tools. You will require latex glazing putty, metal glazing points, pliers, an electric heat gun, and a putty blade.

When you are removing the old glazing compound and points, it's recommended to begin at the top of the sash, and begin to work your way down. This will prevent any paint or wood that is left in the sash from sticking to your tool. If you do remove some of the sash's wood, make sure you use a chisel or utility knife instead of a chemical stripper, since this could cause damage.

After you're done you can sand the wood. Once it is smooth you can apply the oil of linseed or a clear wood sealer to shield it from water and future damage.

There are some quick solutions to repair a cracked double pane window. However, these methods will not repair the damage and should only be used as an interim solution. Using a silicone caulk can aid in sealing the gap, but you need to ensure that you use a high-quality caulk and follow proper application techniques.

Condensation

If you notice moisture or mist between your double glazing glass panes it means that your window seal isn't working. This could be a problem because it prevents the gas or air that is used to insulate from getting trapped between the two panes of glass, so it won't do its job effectively and can lead to temperature changes that result in condensation forming.

A double glazing specialist can easily repair this problem. To correct the issue your window company will remove 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 that will prevent condensation from happening again. They will also apply drying agents to help the area dry out and stop the condensation from happening again.

The other reason why you may notice mist between the glass panes of windows with double glazing is because the framework has moved slightly over time, which breaks the all-important seal. This can be a serious issue as your windows will not work properly and lose their energy efficiency.

It is possible to replace double-glazed window's panes, but this can be expensive and is usually only required if the window is beyond repair. However, if you've discovered a fault in your double-glazed windows, and you're still within the warranty time and the window is still in good condition, it might be possible to have it fixed for free or at least at a lesser cost.

Review your warranty's terms prior to calling the company to find out if they can resolve the issue without replacing 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 you're in, they'll send out a specialist to repair your double-glazed windows. They're able to complete the task quickly. This is a less expensive alternative to purchasing and installing new double-glazed windows. It's also better on the environment!

Broken Locks & Handles

If the handle on your window is broken or difficult to open, it could be a huge issue as it prevents you from using your windows. This also gives burglars an opportunity to break into your home. There are many options to address this issue but the most effective solution is to connect with an uPVC professional. They will be able to fix the issue for you, or provide you with a replacement handle.

There are many types of window lock, but the most popular is the Maco or Mila locks that are commonly found on uPVC frames. These locks employ bayonet rods to lock and these are able to easily seize up. The handle's nose is stuck in the popped-out position and it is unable to return to the wedged lock position. This could be a frustrating problem, but can be fixed with just a few steps.

To resolve the issue to fix the issue, you'll need to first take off the handle, which should be easy enough with the help of a screwdriver. Once the handle has been removed, you should then be able to see the screws holding the lock to the frame. Once the screws have been removed, you can try to grab the bolts using an awl or a pair of pliers. If this is unsuccessful then you might need to insert the tool into the gap between the window and frame (the gap could be different on each end of the window) and make an "u" shape with your hand to attempt to grasp the bolts.

If you are able to free up the bolts that shoot, then you can close your window by adjusting the handle to a closed position. But it won't be able to open again with the handle, as the gearbox (espag or espagnolette) will probably be faulty. You can replace the gearbox (espag or espagnolette) without the shoot bolts in order that the window can be opened using the handle.

Broken Hinges

If your uPVC window hinges aren't functioning properly, you may need to replace or repair them. It could be due to them having been opened with too much force, the hinge snapping or dropping or they were defective in the first place, it can cause problems that make using your window difficult. Fortunately, replacing the hinge is quick and easy, so there's no need to purchase windows from scratch and you can have your old ones fixed instead.

Remove the hinges. This is done by unscrewing the screws that hold the hinges to the frame. Once you've removed the hinges, you can replace them with plywood boards cut to the right dimensions. The plywood should be more dense than the original one to be able to withstand the weight of the window when it is closed and opened. Use wood filler to ensure that the hole left behind by the hinge of the past does not leak or break.

After you've filled in the holes and put on the hinges, then you'll have to paint the doors. Make sure you apply a high-quality paint to ensure that it lasts as long as is possible. After the paint has dried and you are ready to re-attach the window and tighten any loose screws.

Window hinges also require regular maintenance. You can help them last longer by cleaning them regularly on the track of friction and lubricating the hinge mechanism. You can also use a wood preservative to protect them from the elements, which can help to prevent rust and keep them looking great for as long as possible.
