How to Repair Double Glazing Windows
There may be issues with the handles of your double glazing gaskets, hinges and handles. These issues can be resolved without the need to replace your windows entirely, saving you time and money.
Condensation may build up in the space between the two panes. This is usually an indication that the window is defective and requires attention.
1. Broken Panes
A damaged double pane window is a major issue and can expose your home to the elements. It is not always necessary for the entire window sash to be replaced in order to resolve this issue. Double pane windows can be repaired by using a special adhesive placed inside the cracks.
This repair method is usually used to prevent superficial cracks (such as stress cracks) from becoming worse that can happen when the temperature changes cause the glass to expand and contract. If your glass has shattered or cracked, it might be necessary to completely remove the damaged window and replace it.
Sometimes, the seals between two glass panes may become damaged or worn out causing condensation and misting on the windows. Most often, these issues result from moisture that gets trapped between the two glass panes or seeps through the window frame into the wall. Whatever the cause water, it is bad news for your double glazed windows because it can lead to mold growth and water damage, which can be costly to deal with.
To get the misting or condensation issue under control, you should first try wiping your double glazed windows with cold water. This may temporarily fix the issue, particularly when it is humid and warm outside. You can also employ the help of a dehumidifier in cooling the room using double-glazed windows. This is particularly useful during summer.
If the issue persists, a double glazing specialist will visit your home and clean the space between the panes of glass. They can also use an instrument to draw a line of score around the perimeter of your windows, where you should cut the glass using a glass cutter (inexpensive ones can be found in hardware stores). After this is completed, you should take off all the glazing points and putty from the frame of your window opening. It is best to do this while the sash is in place. However, it is easier to work on flat surfaces such as a table.
2. Seals
The window seal is an integral component of double glazing. It plays a significant part in keeping your home energy efficient safe, draught-free and secure. The seal spans the inner perimeter of the uPVC frame and holds an air-tight seal over the gas-filled space between the two glass panes of the window. This is a key element of the insulation effect that double glazing can provide and any problems or failure to the seals will greatly diminish the benefits.
If the seals you have installed aren't doing their job, you will see condensation between the panes. It's not just ugly but it can also cause damp and mould within the home. Mold and damp can cause damage to walls, floorboards as well as furniture. It can be a serious health risk for those suffering from respiratory ailments like asthma.
The positive side is that a majority of double glazing manufacturers will offer repair services for windows without having to replace the entire unit. This is not just cheaper, but also quicker and more eco-friendly. There are other DIY alternatives, like caulking to stop leaks and moisture intrusion, or self-adhesive seals which can be placed directly on the junction of the window sash with the frame.
Calling a professional is the most convenient and efficient solution to a damaged window seal. They can replace the window seal, and also prevent air and moisture from entering your home, which can cause costly damage.
Verify the warranty period of your double glazing. It usually ranges between 10 to 20 years. This could save you money in the event that seals are broken and the windows must be replaced. Some installers may even drill holes into misted double glazing and draw out the moisture to create a new seal and prevent it from misting in the future. But, this could be an interim fix and a plug has to be put into the hole to keep it shut.
3. Locking Mechanisms
Double-glazed windows have air gaps between the glass panes for insulation against temperature fluctuations outside and to keep heat in the house. This type of window can also be described as an insulated unit (IGU). They can give you an impressive energy efficiency that can save on your heating bills. They are not impervious to damage and may require double glazing repair .
Luckily, most of these are relatively easy to fix and much cheaper than replacing the entire window. It is best to speak with a specialist company who offer double glazing repair services, so that you can be sure that the repair is completed efficiently and with minimum fuss. Most of these companies will offer an estimate for free so that you can evaluate the cost and quality of their work.
It is important to check the warranty included with your double-glazed window, as this will usually cover the cost of repairs. This is a standard feature of double glazing and typically lasts for 10 to 20 years, although some companies offer lifetime guarantees.
The seal may be blown when you can't open your double-glazed window or if you notice there appears to be mist between the panes. This could occur if the frame of the window shifts slightly, or if the packing that holds the sheets of glass in place becomes damaged over time.
There are ways that you can repair windows with double glazing by yourself, but it's usually much more efficient to work with an expert company. If you attempt to do it yourself then you should always follow the manufacturer's instructions and use specific tools to complete the task. It is also worth bearing in your mind that if you try to remove the glass yourself then you will be voiding any warranty you may have and could result in a larger cost than if you simply contacted the company from whom you purchased the windows.
After removing the broken glass, you can replace it with plastic spacers. This will ensure that the replacement fits the frame. You can also add any uPVC beading needed. Then you can fit the gasket of a new wedge and lock the window in place.
4. Weatherproofing
If your double-glazed windows are difficult to open or are sagging, there are ways of fixing them. You can oil the handles, hinges, or mechanisms to see if it helps. Another thing that you can try is to replace the gaskets. This will help to improve the performance of your windows, and also stop the entry of draughts and cold air. You can get these at a hardware store, or online and they are easy to install. If you aren't able to tackle this task yourself, you can always hire a professional to install it for you.
Condensation in window panes is a different issue that can be fixed easily. This is usually caused by the seal being damaged that allows moisture to enter the gap between the glass panes. This could cause the glass to cloud up, which is both unattractive and ineffective.
One way of addressing this is to replace the gaskets which can be done easily at home by anyone with a basic DIY knowledge. It is essential to ensure that you make use of a gasket sealer which will give you a strong seal and help to reduce your energy bills. You can also use an elastomer to fill any cracks. This will give your windows an extra boost of weatherproofing.
Another common problem with double glazed windows is that the seals fail. This is often caused by painting near windows or by renovation work done on the property, or general wear and tear. It is crucial to repair your double-glazed windows as quickly as they begin to get misted.
Double-glazed windows are an excellent addition to any home. They provide you with windows that are energy efficient and secure, which will keep the heat in and the weather outside. However, there are times when it is best to replace your double glazed windows, rather than repair them. This could include completely broken panes, extensive rot and frames that are no longer suitable for double glazing units.
