How to Repair Double Glazing Windows
You may experience problems with the handles of your double glazing gaskets, hinges, or handles. These issues can be resolved without needing to replace your windows entirely, saving you time and money.
One common issue is the accumulation of condensation in the gap between the two panes of glass. This is a sign that the window needs to be fixed.
1. Broken Panes
A damaged double pane of glass can expose your home to the elements. However, it is not always necessary to replace the entire window sash to resolve this issue. In fact, double pane windows are usually able to be repaired with the use of a specific adhesive that is put inside the cracks to stop them from worsening.
This short-term option is used to prevent superficial fractures (such stress cracks) that may occur when temperature changes cause the glass to expand and shrink. If your glass has been damaged you may have to remove and replace the entire window.
Sometimes, the seals between the two glass panes may get damaged or worn out causing condensation and misting on the windows. These problems are typically caused by water that is trapped between the glass panes or seeps into the wall through the window frame. No matter the source moisture is a problem for double-glazed windows because it can cause mold and water damage, which can be costly to treat.
You can try to resolve the issue by cleaning the windows of your double-glazed windows with cold, cool water. This will temporarily resolve the issue, especially in the case of warm and humid outside. You can also try using a dehumidifier in the area in which your double-glazed windows are situated which is particularly beneficial during summer.
If the issue persists an expert in double glazing can visit your home and clear the space between your glass panes. They can also use tools to create an outline of a score around the outside of your windows, where you can cut the glass with a glass cutter (inexpensive ones are available in hardware stores). Once you have finished, you should remove all glazing points and putty from the frame of the window opening. It is best to do this while the sash remains in place. However it is much easier to work on flat surfaces like tables.
2. Seals
The window seal is an essential element of double glazing and plays a crucial part in keeping your home energy efficient as well as draught-free and safe. The seal is situated on the inside of uPVC frames and creates an airtight seal in the space between the two glass panes. The seals form an essential part of the double glazing's insulating effect. If they fail or experience problems, this will be reduced.
If the seals you have installed aren't doing their job, you'll notice condensation appearing between the panes. This isn't just unsightly but it can also cause damp and mould within the home. Damp and mould can cause damage to walls, floorboards and furniture and could also have serious health implications for those with respiratory conditions such as asthma.
The majority of double glazing manufacturers provide a service that allows you to repair your windows without having to replace the entire unit. This isn't just cheaper, but it can be a faster and greener option. In the meantime, there are a few DIY options, like caulking to prevent moisture and leaks or lengths of self-adhesive seals that can be applied directly to the junction between the window frame and sash.
In most cases, the simplest and most effective way to tackle failed window seals is to call in an expert. They'll be able to replace the window seal to prevent the ingress of air and moisture, which can cause expensive damage and can make your home more energy efficient.
It's worth checking the paperwork of your double glazing to find out if it has a warranty period. A time span of 10 to 20 years is the norm - this could save you money if the windows need to be replaced due to broken seals. Some installers will even drill misted double glazing and then draw out the moisture to form a new seal to prevent it from leaking again in the future. This is a temporary fix, and a plug needs to be put in to seal the hole.
3. Locking Mechanisms
Double-glazed windows utilize air gaps between the glass panes as insulation against changing temperatures outside and to keep warm in the home. This type of window is also known as an Insulated Glass Unit (IGU). They can give you a lot of energy efficiency that can save on your heating costs. However, they aren't impervious to damage and some issues may occur that require double glazing repairs.
Many of these issues are fixable, and they're much cheaper than having to replace the entire window. It is recommended to contact a specialist firm that provides double glazing repair services, to ensure that the work is done efficiently and with minimum effort. Often these companies will provide an estimate for free to allow you to compare costs and the quality of their work.
Examine the warranty included with your double-glazed window. It will typically cover the costs of repairing. This is a standard feature of double-glazing installations and generally lasts 10 to 20 years, however certain companies offer lifetime warranties.
If you are unable to open your double-glazed window or it appears that there is mist between the panes, then it could be because the seal has blown. This can happen if the frame of your window shifts in a slight manner or when the packaging that holds the glass sheets in place deteriorates over time.
There are many ways you can repair windows with double glazing yourself, however it is generally better to hire a specialist firm. Always follow the instructions of the manufacturer and employ the correct tools. It is also possible to void any warranty if you try to take off the glass yourself. You could end with a bill that is higher than if the company that purchased the windows from contacted you.
After removing the broken glass, you can replace it with plastic spacers. This will ensure that the replacement is a good fit for the frame. You can also add any uPVC beads you require. Then you can fit a new wedge gasket and secure the window into the frame.
4. Weatherproofing
If your double-glazed windows are difficult to open or have sagged there are methods of fixing them. For instance, you can try oiling the hinges, mechanisms or handles to see if it can help. You can also change gaskets to boost your windows' performance and prevent them from opening up to cold air and draughts. They can be found at a hardware store or on the internet. They are easy to install. If you do not have the time to tackle this task yourself, you can ask a professional to install it for you.
Condensation between windows is another issue that can be fixed easily. It is caused by an unsound window seal that allows moisture to get in between the glass panes. This can cause the glass to cloud up, which can be ugly and ineffective.
One option is to replace the gaskets which can be accomplished at home by anyone with minimal DIY background. Gasket sealers are essential for a good seal, and can reduce energy costs. You can also apply a calk in order to fill in any cracks. This will give your windows an additional boost of weatherproofing.
The seals can also fail on double-glazed windows. This is often caused by painting the windows near them or renovation work on the property or just general wear and tear. If you find that your double-glazed windows have become misted, it is important to get them fixed in the earliest time possible.
Double-glazed windows are a great addition to any home. They provide you with windows that are energy efficient and secure which keep the heat in and the weather outside. There are occasions when replacing double glazed windows is the best option. This could be the case with broken panes, extensive rot or frames that are no longer suitable for double glazing units.
