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. They can usually be fixed without having to replace your windows entirely, saving you time and money.
A common issue is the accumulation of condensation in the space between the two glass panes. This is a sign that the window requires to be fixed.
1. Broken Panes
A broken double pane glass can expose your home to the elements. It is not always necessary to have the entire sash of the window to be replaced in order to resolve this issue. Double pane windows can be repaired by using a special adhesive placed inside the cracks.
This short-term repair option is usually used to prevent superficial cracks (such as stress cracks) from deteriorating further, which can occur when temperature changes cause your glass to expand and contract. If your glass is damaged you may have to take it off and replace the entire window.
The seals between two panes can break or be damaged which can cause condensation and misting on the windows. Most often, these issues result from moisture that gets trapped between the two panes of glass or dripping through the window frame into the wall. No matter the source, moisture is bad news for double-glazed windows as it can cause water damage and mold growth that can be costly to deal with.
To get the condensation or misting problem under control, you should first try wiping your double-glazed windows with cold water. This will help temporarily solve the issue particularly when the weather is hot and humid. You can also employ the help of a dehumidifier in cooling the room using double-glazed windows. This is particularly useful in the summer months.
If the issue continues, an expert in double glazing can come to your home and clean the space between the panes of glass. They can also use tools to create lines of scoring around the outside of your windows. This is where you should cut the glass using a glass cutter (inexpensive ones can be found in hardware stores). Once you have finished then you must take off all the glazing points and putty from the frame of the window opening. It is recommended to do this while the sash remains in place. However, it is easier to work on flat surfaces, such as tables.
2. Seals
The window seal is an essential element of double glazing. It helps to keep your home safe, energy efficient, and draught free. The seal is located on the inner frame's uPVC frame and creates an air-tight seal over the gas-filled space between the two panes of glass in the window. This is an essential component of the insulation your double glazing delivers and any problems or failures to seals can significantly reduce this benefit.
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 damp and mould in the home. Mold and damp can cause damage to walls, floorboards and furniture and could cause serious health issues for those suffering from respiratory ailments such as asthma.
The majority of double-glazing manufacturers offer a service that allows you to repair your windows without the need to replace the entire unit. This is not only cheaper, but also quicker and more sustainable. There are other DIY alternatives, like caulking to stop leaks and moisture intrusion or self-adhesive seals that can be applied directly at the junction of the window sash and the frame.
A professional call is the easiest and most efficient solution to a damaged window seal. They can repair the window seal and stop air and moisture from getting into your home, which can cause costly damage.
It's worth checking the paperwork of your double glazing to see whether it comes with a warranty period. A time span of 10 to 20 years is common - this could save you money if your windows need to be replaced because of damaged seals. Some installers will even drill holes in misted double glazing and then draw out the moisture to form a new seal and prevent it from misting in the future. However, this can be a short-term fix and a plug needs to be placed in the hole to keep it shut.
3. Locking Mechanisms
Double glazed windows utilize gaps of air between glass panes to keep out the elements and also to keep heat inside the house. This kind of window is also known as an insulated glass unit (IGU). They can provide you with a lot of energy efficiency which saves on your heating costs. However, they are not indestructible and some problems may occur that require double-glazing repairs.
Fortunately, a majority of them are fairly simple to fix and are much less expensive than replacing the entire window. Contacting a company that offers double glazing repair can ensure that the work is done correctly and without any hassle. Most of these companies will offer a free quote so that you can evaluate the cost and quality of their work.
It is crucial to confirm the warranty that came with your double-glazed windows and, in most cases, pay for a repair. This is a typical feature of most double glazing installation and usually lasts 10 or 20 years although certain companies even offer lifetime warranties.
The seal may have blown if you cannot open the double-glazed windows, or if there appears to be a misty area between the panes. This could happen if the frame of your window moves slightly or if the special packaging that holds the glass sheets is damaged over time.
There are many ways you can repair windows with double glazing by yourself, but it's generally better to hire a specialist firm. If you decide to attempt it yourself, you must always follow the instructions of the manufacturer and use specific tools to complete the task. You will also void any warranty if you attempt to remove the window glass yourself. You may end up paying more than if the company that purchased the windows from contacted you.
After the broken pane has been removed you can replace it using plastic spacers to make sure it fits in the frame. Then, you can add any uPVC beading. After that, you can install a new wedge gasket and secure the window into the frame.
4. Weatherproofing
There are solutions for double glazing windows that are hard to open, or that have been sagging. For instance, you can try oiling the hinges, mechanisms or handles to see if it helps. You can also change gaskets to improve the performance of your windows and stop them from opening up to cold air and drafts. They can be found at a hardware store or online. They are easy to install. If you aren't able to tackle this task yourself, you can ask a professional to complete the task for you.
Condensation in window panes is another issue that is easily fixed. This is caused by a broken window seal that allows moisture to enter between the glass panes. This could cause the glass to fog up, which is unattractive and ineffective.
One option is to replace the gaskets, which can be done easily at home by anyone with a basic DIY knowledge. Gasket sealer is crucial to ensure a tight seal and can help cut down on energy costs. Alternately, you can use a calk to fill any gaps and give your windows an extra boost in weatherproofing.
Another issue with double-glazed windows is that the seals break down. This could be due to painting the windows near them or by renovation work done on the property, or general wear and tears. If you notice that your double glazed windows have started to fog it is crucial to have them repaired as soon as possible.
Double-glazed windows are an excellent addition to any home. They offer energy-efficient and secure windows which keep the warmth inside and the cold outside. There are times when it is better to replace your double glazed windows, rather than repair them. This could be the case with broken panes, extensive rot or frames that are no longer suitable for the double glazing units.
