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 can often be fixed without needing to replace the windows completely, saving you money and time.
One common issue is condensation accumulating in the space between the two panes of glass. This is a sign the window requires to be fixed.
1. Broken Panes
A damaged double pane glass could expose your home to the elements. But, it's not always necessary to replace the entire window sash to address this issue. In fact, double pane windows are usually repaired by the help of a special adhesive that is placed inside the cracks to prevent them from worsening.
This short-term fix is typically used to stop superficial cracks (such as stress cracks) from getting worse, which can occur when temperature fluctuations cause your glass to expand and contract. In the event that your glass has cracked or broken, it could be necessary to remove the damaged window and replace it.
Sometimes the seals between the two glass panes can be damaged or worn out causing condensation and misting of the windows. These issues are usually caused by moisture that is trapped between the glass panes or that is absorbed into the wall through the window frame. Moisture is bad for double-glazed windows, regardless of the source. It can cause water damage and mold which is expensive to repair.
You can attempt to fix the issue by cleaning the windows of your double-glazed windows with cold, cool water. This can help to temporarily fix the issue, especially if the weather is warm and humid. You can also employ a dehumidifier to cool the room using double-glazed windows. This is particularly useful in the summer months.
If the issue persists, a double glazed specialist can visit your home and clear the space between your panes of glass. They can also use tools to create an outline of a score around the perimeter of your windows. This is where you need to cut the glass with a glass cutter (inexpensive ones can be found in hardware stores). After this is completed then you must remove all glazing points and putty from the frame of the window opening. This is best done while the sash is still in place, but it can be easier to work on a flat surface such as a table.
2. Seals
The window seal is an integral component in double glazing and plays a significant part in keeping your home efficient, draught-free, and safe. The seal covers the entire part of the uPVC frame and holds an air-tight seal over the gas-filled space between the two panes of glass that make up the window. The seals are an essential component of double glazing's insulation. If they fail or experience problems it will decrease the effectiveness.
If the seals you have installed aren't doing their job, you'll notice condensation appearing between the panes. This isn't just unsightly; it can lead to damp and mould in the home. It can damage floors, furniture, walls and cause serious health problems for those suffering from respiratory ailments such as asthma.
Most double glazing manufacturers offer a service that permits you to repair your windows without the need to replace the entire unit. This isn't just less expensive however, it can also be a faster and more environmentally friendly alternative. In the meantime, there are some DIY alternatives, such as using caulking to tackle moisture and leaks or lengths of self-adhesive rubber seals which can be applied directly to the window frame's junction frame and sash.
In the majority of cases, the simplest and most effective method to tackle failed window seals is to contact a professional. They'll be able to replace the window seal to stop the infiltration of moisture and air which can cause costly damage and can help your home remain energy efficient.
It's worth checking the documentation of your double glazing to see whether it has a warranty period - 10 to 20 years is typical - this could save you money in the event that the windows require replacement due to broken seals. Some installers will drill the misted double glazing to remove the moisture and create a new seal. This will prevent it from misting in the future. This is a temporary fix and a plug must be installed to keep the hole closed.
3. Locking Mechanisms
Double-glazed windows utilize air gaps between the glass panes to provide insulation against temperature fluctuations outside and also to keep heat in the house. This kind of window is also called an insulated glass unit (IGU). These windows can save money on your heating bills by reducing the energy consumption. They are not indestructible, and they may need repair to the double glazing.
Fortunately, the majority of these are relatively easy to fix and are much less expensive than replacing the entire window. Contacting a company that offers double glazing repair will ensure the job is done properly and with minimal fuss. Most of these companies will offer an estimate for free so that you can evaluate the cost and quality of their work.
Examine the warranty that came with your double-glazed window. It usually covers the costs of a repair. This is a common feature of the majority of double glazing installations and typically lasts for 10 or 20 years however some companies have even offered lifetime warranties.
The seal could be blown when you can't open your double-glazed window or if there appears to be a misty area between the panes. This could occur if the frame of the window moves slightly, or if the packing that keeps the glass sheets in place becomes damaged over time.
You can repair double-glazed windows yourself, but it's usually simpler to employ a professional. It is important to adhere to the guidelines of the manufacturer and employ the right tools. It is also possible to void any warranty if you try to remove the glass by yourself. You might end with a bill that is higher than if the company you purchased the windows from had contacted you.
After removing the broken glass then you can replace it with plastic spacers. This will ensure that the new glass is a good fit for the frame. You can also add any uPVC beading needed. Then you can put in the gasket with a new seal and secure the window.
4. Weatherproofing
There are ways to fix double glazing windows that are hard to open or have been sagging. For instance, you can try oiling the hinges, mechanisms or handles to see if it aids. Another thing you can do is replace the gaskets, which will help to enhance the performance of your windows and prevent them from letting in draughts or cold air. You can get these at a hardware store, or online, and they are quite easy to install. If you aren't able to do it yourself, you can always hire a professional to install it for you.
Condensation between windows is a different issue which can be easily solved. It usually happens due to an unsound seal, which will allow moisture to get into the space between the glass panes. This can cause mist to develop on the glass, which is both ugly and ineffective.
Anyone with a bit of DIY knowledge can easily replace the gaskets. It is very important to ensure that you apply a gasket sealer which will provide a good seal and will help reduce energy bills. You can also make use of a calk to fill any gaps and give your windows an extra boost in weatherproofing.
Another issue that is common to double-glazed windows is that the seals begin to break. This could be due to paint being applied near the windows, home renovations or general wear and tear. If you find that your double-glazed windows have started to fog, it is important to fix them as soon as possible.
