How to Repair Double Glazing Windows
If you have double-glazed windows there are times when you might encounter problems with the gaskets, hinges, and handles. You can often resolve these issues without having to replace the entire window, thereby saving money and time.
Condensation can build up in the space between the two panes. This is a sign the window needs to be repaired.
1. Broken Panes
A damaged double pane glass could expose your home to the elements. However, it's not always necessary to replace the entire window sash to address this issue. In fact double pane windows are typically able to be repaired with the use of a specific adhesive that is inserted into the cracks to stop them from getting worse.
This repair method is often used to prevent superficial cracks (such as stress cracks) from deteriorating further, which can occur when temperature fluctuations cause the glass to expand and contract. If your glass has broken, you may need to remove and replace the entire window.
The seals between two panes can wear out or be damaged, causing misting and condensation on windows. These problems are usually caused by moisture that is trapped between the glass panes, or it seeps into the wall through the window frame. Moisture is bad for double-glazed windows, regardless of its source. It can cause mold and water damage, which are costly to fix.
To get the condensation or misting problem under control, first try wiping your double-glazed windows with cold water. This can temporarily solve the issue, particularly when it is hot and humid outside. You can also employ a dehumidifier to help cool the room using double-glazed windows. This is particularly helpful in summer.
If the issue persists the double glazed specialist can visit your home and clean out the space between your panes of glass. A tool can be used to draw an outline of a score line around the perimeter of your windows, where you can cut the glass using a glass cutter. After this is completed then you must remove all the glazing points and putty from the frame of the window opening. This should be done with the sash still in place, however it's easier to work on a flat surface like a table.
2. Seals
The window seal is an essential element of double glazing. It helps to keep your home secure and energy efficient as well as free of draft. The seal spans the inner perimeter of the uPVC frame and provides an air-tight seal over the gas-filled space between the two glass panes of the window. The seals are an essential part of the double glazing's insulation. If they fail or experience problems, this will be reduced.
If your seals aren't performing their job, you'll notice condensation 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 be a serious health risk for those with respiratory conditions like asthma.
The good news is that most double glazing companies will provide a service to repair windows without replacing the entire unit. This is not just cheaper but also faster and more environmentally-friendly. There are other DIY options, such as caulking to stop leaks and moisture intrusion, or self-adhesive seals that are placed directly on the junction of the window sash with the frame.
In the majority of cases, the simplest and most effective way to fix a damaged window seal is to call in an expert. They can repair the window seal and prevent air and moisture 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 could save you money in the event that seals are broken and the windows need to be replaced. Some installers may even drill holes into misted double glazing and then draw out the moisture in order to create a new seal to prevent it from misting again in the future. But, this could be temporary and a plug will need to be inserted into the hole in order to keep it shut.
3. Locking Mechanisms
Double-glazed windows have gaps of air between the glass panes to insulate against varying outside temperatures and to help keep heat inside the house. This kind of window could also be called an Insulated Unit (IGU). These windows can save money on heating bills by reducing the energy consumption. However, they aren't 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. It is recommended to contact a specialist firm that provides double glazing repair services as this will ensure that the work is carried out correctly and with minimal fuss. These companies usually offer an estimate for free to let you assess the cost and the quality of their work.
It is crucial to confirm the warranty that came with your double-glazed windows as it will typically pay for a repair. This is a standard feature of double-glazing installations and generally lasts 10 to 20 years, however certain companies offer lifetime warranties.
The seal may have blown if you cannot open your double-glazed window, or if there appears to be mist between the panes. This can happen if the frame of your window shifts slightly or if the packaging that holds the glass sheets in place gets worn out over time.
There are a variety of ways you can repair double-glazed windows by yourself, but it's usually much more efficient to work with an expert company. You should always follow the instructions of the manufacturer and make use of the correct tools. It is also worth bearing in your mind that if you try to remove the glass yourself then you'll be breaking any guarantee that you might have and may result in a larger bill than if you had simply made contact with the company from whom you bought the windows.
Once the broken pane is removed, you can put it back using plastic spacers to make sure that it fits into the frame and add any necessary uPVC beading. Then, you can install the gasket with a new seal and secure the window.
4. Weatherproofing
There are solutions to fix double glazing windows that are difficult to open or have sagged. Oil the handles, hinges, or mechanisms to see if it helps. You can also replace the gaskets to improve the performance of your windows and stop them from letting in cold air and drafts. You can purchase them at a hardware store or online, and they are quite easy to install. If you do not have the time to tackle this task yourself, you can hire a professional to install it for you.
If you have condensation between the window panes, this is also a problem that can be fixed easily. It usually happens due to a broken seal that allows moisture to get into the space between the glass panes. This can cause mist to develop on the glass, which is unattractive and ineffective.
One option is to replace the gaskets which can be accomplished at home by anyone with minimal DIY background. It is essential to ensure that you make use of a gasket sealer that will give a solid seal and help to reduce energy bills. You can also make use of a calk to fill any cracks and give your windows that extra boost in their weatherproofing.
Another issue that is common to double-glazed windows is that the seals break down. This can happen due to paint being applied near the windows, renovations, or just general wear and tear. If you discover that your double-glazed windows have started to fog it is crucial to fix them as soon as you can.
Double-glazed windows can be a wonderful addition to any home. They are energy-efficient and secure windows, which will keep the warmth inside and the cold outside. There are times when replacing double glazed window is the best option. This can include broken panes, extensive rot or frames that are no longer suitable for double glazing units.
