How to Repair a Double Glazed Window
Double glazing is an effective method to boost the efficiency of your home's energy use and help to insulate it. It is susceptible to problems such as condensation and draughts.
Repairs are often more cost-effective than replacement. Let's look at a few of the most popular options for double-glazed window repairs:
Broken Panes
The first step is to take off the broken pane. Wear thick work gloves, and put a box of cardboard nearby to collect any fragments of glass that fall while you work. Use a utility knife to cut the glass around the broken windowpane and ensure that you wear eye protection and a mask because of the possibility of lead entering the frame. If clips or nails are holding the windowpane in, use pliers to pull them out. Once the glass is removed, remove any old putty or metal glazing points. A heat gun can be used to soften the putty if necessary.
After the old putty is gone, re-grout grooves and apply silicone caulk using a silicon caulking tool. Before applying the final caulking it is a good idea to check the fit of the new window into its frame. Make sure the grooves are free of any gunk, rust, or paint and that they are not too narrow for the window to sit in.
Replace the sash next with a wood molding to match the windowframe. If the frame of the window is in a poor state it could be easier and more cost effective to replace the entire window unit rather than one pane.
In the past double pane windows were made of two pieces of glass separated by an air spacer. upvc window repairs near me were then filled with air or an gas for insulation. But in recent years, manufacturers have switched to glass units that are insulated (IGs) that are more energy efficient and resistant to seal failure. In windows that have failed IG the moisture from the outside seeps into the gap and condenses inside the glass. This process eventually erodes the properties of insulation, leaving a film of haze on the glass.
A glass repair specialist could replace the entire IG or replace just the damaged surface. This procedure can be costly and time-consuming, however it is the only solution to fix an issue with the seal that allows water to leak into the home. Selecting high-quality windows from a reputable manufacturer and then having them installed by a skilled technician can help prevent future issues with the seals.
Misty Panes
The window's frame can hold three or two panes that are separated by air-filled spaces. The air, which is usually filled with argon gas to ensure better energy efficiency, helps to keep warm air in and cold air out. Unfortunately, windows can start to fail and you'll notice a cloud of haze growing between the panes of the glass. It could be that it's time to buy a new window, but you can't just replace the damaged pane.
In most instances, a stained window indicates an issue with the seal between the two panes of glass. The condensation or mist indicates that moisture has penetrated and has damaged the insulating qualities of the double-glazing. This is why it's important to pay attention to the maintenance of your windows and keep them clean.
Condensation between the panes of your windows can indicate that there's a lot of humidity in the home It's therefore essential to dehumidify as well as take other measures to increase the airflow in areas where this happens often. If the condensation is visible only on one side of your window or between the panes, then you'll need to have the seal repaired.
It is not possible to reseal a double-glazed windows in order to restore the original energy efficiency. If the seal is damaged the gap opens up cold air to enter your home, and warm air out. This will reduce the insulating capacity of your home which will make it more expensive to heat.
Some businesses offer a service where they drill holes into the outside of your window and drain out the condensation, but this is only a short-term solution and won't last for more than six months. It's not recommended you attempt to do this by yourself, as it could be very risky without the proper tools and experience. A double-glazing specialist will use specific equipment to safely remove the condensation and install air vents that will ensure that there is no future misting.
Frame Fragment Damage
Even with the best of care double glazing is susceptible to developing problems. Some are minor and can be corrected but others are more serious and need to be replaced entirely. This is a choice that should be taken by the owner of the property, taking into consideration the level of benefits they receive from their double glazing and how much value it will bring to their home.
If you are having difficulty opening and closing your windows it could be due to misting or an issue with the frame. If this is the case, you need to have your windows fixed as quickly as possible to prevent further damage to your double glazing and to prevent water from getting into the insulated gap.
Over time, the protective layer that holds the glass sheets in their frames and stops them from moving could get worn out. This can cause the glass sheets to move, which could cause the seal to break and lead to misting. Mist may also form in the space between the panes that is insulating, again indicating that the seal is broken and it's time for double glazing repairs.
A common issue is windows that have sagged over time and are difficult to open or close. This can be fixed by changing the mechanisms and hinges. It is worth remembering that a lot of new double glazed windows are covered by a guarantee and in this instance it would be an ideal idea to contact the company from whom you bought your double glazing to get details regarding what to do.
Double-glazed windows can be repaired yourself, but it's usually better to consult with a professional to benefit from their expertise and experience. Professionals are able to identify the issue quickly and efficiently, and then make the required repairs to your double glazing. You can also avoid voiding your warranty by not attempting to repair your windows without having the right skills.
Weather Damage
Double pane windows are resistant to weather damage. However in the event that you live in an area that is prone to icestorms hail, high winds and torrential rain, your window frames and seals could be terribly damaged. The best way to make sure your windows stay in good working order is to regularly inspect them and repair minor dents and chips immediately you discover them.
Blown windows are among the most serious issues you may encounter with double glazing. When there is a gap between the two glass panes air and moisture could be able to enter your home. This is usually an indication of deterioration in the seals or a problem with the insulation material between the panes.
Condensation between the panes is yet another problem that double-glazed windows can cause. This occurs when the warm air inside your home is warmer than the outside air. The difference in temperature causes the warmer air to expand, which can cause the window's seals to break or weaken over time.
Foggy windows are a common problem with double-glazed windows. This is a typical issue that can be resolved without replacing the IGU. This is usually a sign that the seals between your window's panes need to be resealed.
To do this, you'll need to drill a hole in between the window panes. You will need to drill a hole large enough to accommodate pipe cleaners or another long object, with cloth at the end. The cloth ends will be used to wash your windows clean and remove any condensate left behind. This will help to create a more secure seal and avoid any further fogging.
It's important to keep in mind that this is temporary solution for your windows that are hazy. Condensation will return when it rains or there is an increase in humidity. If you are seeking a permanent solution, you'll need to replace your old IGU.
