How to Repair Double Glazing Windows
You may experience problems with the handles of your double glazing, hinges, and gaskets. They can usually be fixed without the need to replace the windows completely costing your time and money.
One common issue is condensation accumulating in the space between the two panes of glass. This is a sign the window must be repaired.
1. Broken Panes
A damaged double pane window is a serious issue and could leave your home exposed to the elements. It is not always necessary to have the entire sash of the window to be replaced in order to fix this problem. Double pane windows can be fixed by using an adhesive that is specifically designed to be placed inside the cracks.
This short-term fix is often used to prevent superficial cracks (such as stress cracks) from getting worse, which can occur when the temperature changes cause your glass to expand and contract. If your glass has broken, you may need to remove and replace the entire window.
Sometimes the seals between the two glass panes may become damaged or worn out, causing condensation and misting on the windows. Typically, these problems are caused by moisture that is trapped between the two glass panes or leaks through the window frame and into the wall. Moisture is a problem for double-glazed windows regardless of the source. It can cause water damage and mold which is expensive to fix.
To get the misting or condensation issue under control, first try wiping your double-glazed windows with cold water. This will temporarily resolve the issue, especially when it is hot and humid outside. You can also consider using a dehumidifier in the area where your double-glazed windows are located, which can be particularly helpful during the summer.
If the issue continues, 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 lines of scoring around the perimeter of your windows, where you should cut the glass using a glass cutter (inexpensive ones 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 the window opening. This should be done with the sash still in place, but it is possible to work on a flat surface, such as a table.
2. Seals
The window seal is an essential element of double glazing. It is essential to keep your home safe and energy efficient, as well as free of draft. The seal is located on the inside of uPVC frames and forms an airtight seal inside the space between the two panes of glass. The seals are a vital component of double glazing's insulating properties. If they fail or experience problems they will reduce the insulation.
If the seals you have installed aren't doing their job, you'll notice condensation appearing between the panes. This isn't just a nuisance but it can also cause mould and damp in your home. It can cause damage to flooring, furniture, walls and cause serious health problems for those suffering from respiratory ailments like asthma.
The positive side is that a majority of double glazing companies will provide the option of repairing windows without having to replace the entire unit. This is not just cheaper, but also quicker and more environmentally-friendly. In the meantime, there are some DIY options, like caulking to prevent water leaks and moisture penetration, or lengths of self-adhesive seals which can be applied directly to the junction between the window frame and sash.
In the majority of cases, the simplest and most effective way to tackle failed window seals is to contact an expert. They can repair the window seal and prevent moisture and air from entering your home, which can cause expensive damage.
It's worth checking the documentation of your double glazing to find out whether it has an assurance period of 10 to 20 years is the norm - this could save you money if the windows have to be replaced because of broken seals. Some installers drill holes into the misted double glazing to remove the moisture and make the new seal. This will stop it from misting again in the future. However, this is an interim fix and a plug needs to be put into the hole to keep it closed.
3. Locking Mechanisms
Double glazed windows use gaps of air between glass panes in order to insulate against varying outside temperatures and to help keep heat in the house. This kind of window can be referred to as an Insulated Unit (IGU). They can provide you with an impressive energy efficiency that can save on your heating bills. But, they're not indestructible and some problems may occur that require double-glazing repairs.
The majority of these issues are fixable, and they're much cheaper than having to replace the entire window. A company that offers double glazing repair will ensure the job is completed correctly and without any hassle. Often these companies will provide an estimate for free so that you can compare prices and the quality of their work.
Examine the warranty that came with the double-glazed window. It usually covers the cost of repairs. This is a common feature of double glazing and generally lasts 10 to 20 years, although some companies offer lifetime guarantees.
If double glazing window repairs cannot open your double glazed window or it appears that there is a cloud of mist between the panes, it could be because the seal has blown. This could happen when the frame of the window moves slightly, or if the packaging that holds the glass sheets in place becomes damaged over time.
There are a variety of ways you can fix a double glazed window yourself, however it is usually much more efficient to work with a professional company. If you decide to attempt it yourself then you should follow the manufacturer's guidelines and use the right tools to complete the task. You will also void any warranty if trying to take off the glass by yourself. You may end with a bill that is higher than if the business that bought the windows had just called you.
Once the broken pane is removed you can replace it using plastic spacers to make sure it fits in the frame and add any necessary uPVC beading. Then, you can put in an additional wedge gasket and lock the window in the frame.
4. Weatherproofing
If your double-glazed windows are difficult to open or are sagging There are a few options for fixing them. Oil the hinges, handles or mechanisms to see if it improves. Another thing you can try is to replace the gaskets. This will enhance the performance of your windows and stop them letting in draughts and cold air. You can purchase them from a hardware store or on the internet and they are a breeze to install. If you aren't able to tackle this task yourself, you can ask a professional to complete the task for you.
If you have condensation between your window panes, this is also something which can be fixed easily. It usually happens due to an unsound seal that allows moisture to enter the gap between the glass panes. This can cause mist to develop on the glass, which is both undesirable and ineffective.
One way of addressing this is to replace the gaskets which can be done easily at home by anyone with minimal DIY background. It is crucial to ensure that you use a gasket sealer, which will provide a good seal and will help reduce your energy bills. You can also use a calk in order to fill any cracks. This will give your windows an additional boost of weatherproofing.
Another issue with double-glazed windows is that the seals fail. This can be caused by paint being applied near the windows, home renovations, or just general wear and wear and tear. It is important that you repair your double-glazed windows as soon as they begin to get misted.
Double glazed windows can be an excellent addition to your home. They provide you with energy efficient and secure windows that will keep the weather out and the heat in. There are occasions when replacing double glazed windows is the best option. This could be the case with frames that are damaged or broken, or panes that are not suitable for double glazing.
