How to Repair Double Glazing Windows
If you have double-glazed windows there are times when you might encounter problems with the handles, hinges and gaskets. These issues can be resolved without needing to replace your windows entirely costing your time and money.
One common issue is the accumulation of condensation in the space between the two panes of glass. This is a sign the window needs to be fixed.
1. Broken Panes
A damaged double pane glass can expose your home to the elements. However, it is not always necessary to replace the entire window sash in order to resolve this issue. In fact double pane windows are usually repaired by the use of a specific adhesive that is inserted into the cracks to prevent the cracks from getting worse.
This short-term method is employed to prevent superficial fractures (such stress cracks) that can occur when temperature changes cause the glass to shrink and expand. If your glass has been damaged, you may need to remove and replace the entire window.
Sometimes the seals between the two panes of glass can become damaged or worn out causing condensation and misting on the windows. These problems are usually caused by moisture trapped between the glass panes or that seeps into the wall through the window frame. Whatever the cause, moisture is bad news for windows with double glazing as it can cause water damage and mold growth, which can be costly to deal with.
You can try to resolve the issue by cleaning your double-glazed windows with cold, lukewarm water. This may help temporarily solve the issue, especially when the weather is hot and humid. You can also employ a dehumidifier to help cool the room using double-glazed windows. This is particularly helpful during summer.
If the issue persists, a double glazed specialist can come to your home and clean out the space between your glass panes. They can also employ tools to create an outline of a score around the perimeter of your windows, where you can cut the glass with a glass cutter (inexpensive cutters are available in hardware stores). Once you have finished and you are done, you need to remove all the glazing points and putty from the frame of your window opening. This is best done with the sash still in place, although it's easier to work on a flat surface, such as a table.
2. Seals
The window seal is an essential component in double glazing and plays a vital part in keeping your home energy-efficient, draught-free, and safe. The seal is located on the inner perimeter of uPVC frames and creates an airtight seal within the space between the two glass panes. This is an essential component of the insulation the double glazing provides, and problems or frank failures in the seals could greatly diminish the benefits.
If your seals aren't doing their job, you'll see condensation between the panes. It's not just ugly; it can lead to damp and mould within the home. It can cause damage to floors, furniture, walls and create serious health issues for those with respiratory conditions such as asthma.
The good news is that the majority of double glazing companies will provide repair services for windows without replacing the entire unit. This isn't just less expensive and more affordable, but it could be a quicker and greener option. In the meantime, there are some DIY options such as using caulking to tackle leaks and moisture penetration or lengths of self-adhesive rubber seals that can be applied directly to the junction between the window frame and sash.
Contacting a professional is the most convenient and effective solution to a failed window seal. They can replace the window seal, and also prevent moisture and air from entering your home, which could cause expensive damage.
Make sure you know the warranty duration of your double glazing. It is usually between 10 to 20 years. This can save you money in the event that the seals are broken and the windows must be replaced. Some installers will even drill holes in misted double glazing and then draw out the moisture to create a new seal and prevent it from misting in the future. However, this is temporary and a plug has to be put into the hole in order to keep it closed.
3. Mechanisms for Locking
Double-glazed windows utilize air gaps between the glass panes as insulation against the changing temperature outside and also to keep warm inside the house. This kind of window is also called an IGU or insulated glass unit (IGU). They can offer you a lot of energy efficiency, which can lower your heating bills. However, they are not impervious to damage and some issues may occur that require double glazing repairs .
Fortunately, the majority of them are fairly simple to fix and are much less expensive than replacing the entire window. A company that offers double glazing repair will ensure the work is done correctly and with minimum fuss. Most of these companies will offer a free quote so that you can compare costs and the quality of their work.
It is crucial to confirm the warranty included with your double glazed window, as this will usually cover the cost of a repair. This is a typical feature of most double glazing installation and typically lasts for 10 or 20 years although some companies have even offered lifetime guarantees.
If you cannot open your double-glazed window or it appears there is a cloud of mist between the panes, then it is probably because the seal has blown. This could happen when the frame of the window shifts in a slight manner, or when the packing that holds the glass sheets in place becomes damaged over time.
You can fix double-glazed windows yourself, but it's easier to hire a specialist. If you attempt to do it yourself, then always follow the manufacturer's instructions and use specific tools to complete the task. It is also worth bearing in the mind that if you attempt to remove the glass yourself, you'll be breaking any guarantee that you might have and could end up paying a higher cost than if simply made contact with the company from whom you purchased your 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 put in an additional gasket and seal the window.
4. Weatherproofing
There are solutions for double glazing windows that are difficult to open, or that have become sagging. For example, you can try oiling the hinges, mechanisms or handles to see if it can help. Another thing that you can do is replace the gaskets. This can enhance the performance of your windows and stop them letting in draughts and cold air. These are available in a hardware store or online. They are simple to install. You can seek out an expert if you don't intend to do it yourself.
Condensation between window panes is another problem that is easily fixed. It is caused by the window seal being damaged, which allows moisture to enter between the glass panes. This can cause mist to form on the glass, which is unattractive and ineffective.
Anyone with a little DIY experience can easily replace gaskets. Gasket sealers are essential for a strong seal and will help reduce the cost of energy. Alternately, you can make use of a calk to fill any gaps and give your windows that extra boost in their weatherproofing.
The seals could also fail on double-glazed windows. This can happen due to paint being applied near the windows, property renovations, or just general wear and wear and tear. It is essential to repair your double-glazed windows as quickly as they become misted.
Double-glazed windows are an excellent addition to your home, providing you with energy efficient and secure windows that keep the elements out and the heat in. There are times when it is better to replace your double glazed windows rather than repair them. This can include broken panes, extensive decay and frames that are no longer suitable for the double glazing units.
