How to Repair Double Glazing Windows
If you have double glazing there are times when you might encounter problems with the handles, hinges and gaskets. These issues can be resolved without having to replace the windows completely, saving your time and money.
One of the most common issues is the accumulation of condensation in the gap between the two panes of glass. This is usually a sign that the window has become damaged and requires attention.
1. Broken Panes
A broken double pane window is a serious problem and could expose your home to the elements. But, it's not always necessary to replace the entire window sash to resolve this problem. Double pane windows can be repaired with an adhesive that is specifically designed to be placed inside the cracks.
This short-term solution is used to avoid superficial fractures (such stress cracks) that may occur when temperature changes cause the glass to expand and shrink. If your glass has broken it may be necessary to remove and replace the entire window.

Sometimes, the seals between two glass panes may be damaged or worn out, causing condensation and misting of windows. These problems are usually caused by water that is trapped between the glass panes, or it is absorbed into the wall through the window frame. Whatever the cause moisture is a problem for windows with double glazing as it can cause mold growth and water damage, which can be costly to deal with.
You can try to control the problem by wiping down your double-glazed windows with cold, cool water. This can help to temporarily resolve the problem especially in the case of warm and humid. You can also employ a dehumidifier to cool the room with your double-glazed windows. This is particularly useful in summer.
If the problem persists an expert in double glazing can visit your home and remove the space between your glass panes. A tool can also be used to create an outline of a score line around the outside of the windows, which allows you to cut the glass using a glass cutter. After this, remove all the glazing points from the window opening. This is best 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 is essential to keep your home secure, energy efficient, and draught free. The seal is located at the outer edge of uPVC frames and creates an airtight seal within the space between the two panes of glass. The seals are a vital part of the double glazing's insulating effect. If they fail or experience problems it will decrease the effectiveness.
If your seals aren't doing their job, you'll notice condensation appearing between the panes. It's not just ugly and can cause damp and mould in the home. The effects of mould and damp can cause damage to floors, walls and furniture and could be a serious health risk for those with respiratory conditions like asthma.
The good news is that most double glazing manufacturers offer a service to repair windows without having to replace 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 DIY options such as using caulking to tackle moisture and leaks or lengths of self-adhesive seals which can be applied directly to the window frame's junction sash and frame.
In the majority of instances, the easiest and most effective way to fix a damaged window seal is to contact an expert. They can repair the window seal, and also prevent air and moisture from getting into your home, which could cause expensive damage.
Check the warranty period on your double glazing. It is usually between 10 to 20 years. This can save you money in the event that the seals have failed and the windows must be replaced. Some installers will drill holes in the misted double glazing to remove the moisture and then create the new seal. This will prevent it from misting in the near future. However, this is temporary and a plug has to be inserted into the hole to keep it shut.
3. Mechanisms for Locking
Double glazed windows use gaps of air between glass panes in order to insulate against varying outside temperatures and to help keep the heat inside the home. This type of window can also be described as an insulated unit (IGU). They can give you a lot of energy efficiency which saves on your heating costs. But, they're not indestructible and some problems may occur that require double-glazing repairs.
Fortunately, a majority of them are easy to fix and are much less expensive than replacing the entire window. It is best to contact an expert company that offers double glazing repair services, as this will ensure that the job is completed correctly and with minimal effort. These companies will often provide a free estimate to let you assess the cost and the quality of their work.
Check the warranty that came with your double-glazed window. This will usually cover the cost of repairs. This is a typical feature of most double glazing installation and usually lasts 10 or 20 years although some companies offer lifetime guarantees.
The seal may be blown when you can't open the double-glazed windows, or if there appears to be mist between the panes. This could happen if the frame of your window moves slightly or if the packaging that holds the glass sheets in place deteriorates over time.
You can fix double-glazed windows yourself, but it's usually more cost-effective to hire a professional. If you attempt to do it yourself then you should always follow the instructions of the manufacturer and use the right tools for the job. It is also important to keep in your mind that if you try to remove the glass yourself, you will be voiding any guarantee that you might have and may result in a larger bill than if you had simply contacted the company from whom you bought the windows.
Once the damaged pane is removed you can replace it with plastic spacers to make sure that it fits into the frame. You can also add any uPVC beading. You can then fit an additional gasket and seal the window.
4. Weatherproofing
There are solutions for double glazing windows that are hard to open or have sagged. For instance, you can try oiling the hinges, mechanisms or handles to see if that aids. Another thing that you can try is to replace the gaskets, which can increase the efficiency of your windows and stop the entry of draughts and cold air. These are available at a hardware shop or on the internet. They are simple to install. You can seek out a professional if you don't intend to do it yourself.
If you notice condensation between the window panes, this is also a situation that can be fixed easily. This is usually caused by an unsound seal that allows moisture to enter the gap between the glass panes. This can cause mist to form on the glass, which is ugly and ineffective.
One way of addressing this is to replace the gaskets, which can be done easily at home by anyone with little DIY experience. It is essential to ensure that you use a gasket sealer, which will give you a strong seal and help to reduce energy bills. Alternately, you can use a calk for filling any gaps and give your windows an extra boost in their weatherproofing.
Another common problem with double-glazed windows is the seals break down. This is often caused by painting near windows or by renovation work done on the property, or general wear and tear. If you notice that your double glazed windows have become misted, it is important to get them fixed as soon as you can.
