How to Repair a Double Glazed Window
Double glazing is an effective method to insulate your home and improve its energy efficiency. upvc window repairs could cause problems like condensation and draughts.
Repairs are often more cost-effective than replacement. Let's look at a few of the most common options for repairs to double-glazed windows:
Broken Panes
The first step is removing the broken pane. Wear thick work gloves, and keep a box of cardboard nearby to catch any pieces of glass that fall as you work. Utilize a utility knife to cut the glass around the window pane that has been broken, making sure to wear a mask and eye protection due to the possibility of lead in the frame. If nails or clips are holding the windowpane in the frame, you can use pliers to pull them out. Scrape off any old putty or metal glazing points after the glass has been removed. A heat gun can be used to soften the putty if necessary.
Once the old putty is removed Re-grout the grooves and apply a new caulk using a silicone caulking gun. It is a good idea to test the fit of the new window within its frame prior to applying final caulking. Make sure that the grooves are free of any rust, gunk or paint and that they aren't too narrow for the window to sit in.
Replace the sash after that by a wooden molding to match the frame. If the frame of the window is in a poor state, it may be easier and cost-effective to replace the whole window unit instead of one pane.
In the past double pane windows were constructed of two pieces of glass, separated with a spacer. They were then filled with either air or an insulation gas. In recent years, manufacturers have made the switch to insulated-glass units (IGs), which are more energy efficient and resistant to failure of seals. In a double-pane windows with a damaged IG the moisture from the air outside is absorbed into the gap and condenses on the inside of the glass. This cycle eventually breaks the insulating properties that are present in the IG and leaves an unclean substance on the glass.
To fix a damaged IG glass, the glass repair expert can replace the entire unit, or can replace just the broken surface of the glass. This procedure can be costly and time-consuming, however it is the only way to fix a defective seal that allows water to leak into the home. Installing high-quality windows by a technician who has the experience and purchasing windows from a reputable manufacturer can help avoid any future problems with seals.
Misted Panes
The frame of the window holds two or three panes separated by air-filled spaces. The air, often filled with argon gas to ensure better energy efficiency, helps to keep warm air inside and cold air outside. Unfortunately, windows can start to break down, and you will notice a cloud of haze building up between the panes of glass. You may think it's time to replace the entire window however, it's not as simple as removing the damaged pane and replacing it.
A window that is misty is typically an indication that the seal between two panes of glass has failed. The mist or condensation indicates that moisture has entered and damaged the insulation of the double glazing. It is essential to maintain your windows and keep them clean.
Condensation that forms between the panes your windows is a sign that there's a lot of humidity in the house Therefore, it's essential to dehumidify and take other steps to improve ventilation in the areas where this happens frequently. If the condensation is only visible on one side of the window, or is visible between the panes of the glass, it means that there's a problem with the seal and you'll need to fix it.
There is no such thing as resealing a double-glazed window to bring back its energy efficiency. When the seal fails, the gap will allow cold air to enter your home, and warm air to escape. This will affect your home's insulating ability and make it more costly to heat.
Some companies provide a service in which they drill holes into the exterior of your window to drain out the condensation. However, this is a temporary solution that is unlikely to last more than six months. It is also not recommended that you attempt this yourself, as it could be very risky without the right tools and expertise. A double-glazing specialist will use specific equipment to safely remove the condensation and install air vents that will aid in preventing the possibility of misting in the future.
Frame Damage
Even with the best care, double glazing can develop faults. Some are minor and can be fixed, while others are more serious and need to be replaced completely. This is a decision that is taken by the owner of the property, taking into consideration the level of benefits they will receive from double glazing and the value it will bring to their home.
If you are having difficulty opening and closing your windows it could be caused by misting or an issue with the frame. It is recommended to repair your windows as quickly as you can to prevent further damage to the double glazing.
The frames of double glazed windows are designed to hold the glass panes in their place and stop them from shifting, but with time, the special packaging that aids in this may wear down. 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 and the glass, indicating that the seal has broken and it is now time to make double glazing repairs.
The most frequent issue is windows that have sagged over time and are difficult to open or close. This can usually be repaired by changing the hinges or mechanisms. Remember that many double-glazed windows are covered by an insurance policy. In this instance, you should contact the company from which you purchased your double-glazed window to find out what you can do.

Weather Damage
Double pane windows are impervious to weather damage. However in the event that you live in an area that is prone to icestorms, hail, high wind and torrential rainfall windows and sealings can be seriously damaged. The best way to ensure that your windows stay in good shape is to regularly inspect them and fix minor dents and chips when you detect them.
Blown windows can be one of the most serious issues you could face with double glazing. When there is a gap between the two glass panes air and moisture can get into your home. This is usually an indication of deterioration or a problem in the insulating material that divides the panes.
Another issue that many homeowners face with double-glazed windows is condensation between the panes. This occurs when the warm air inside your home is warmer than the outside air. The warmer air expands because of the difference in temperature which could cause window seals be damaged or break over time.
Foggy windows are also a common issue with double-glazed windows. The good thing is that this is an issue that can be resolved without having to replace the IGU. This is a sign that your window's seals need to be resealed.
You will need to drill an opening between the window panes. It should be big enough to allow for the installation of an extended pipe cleaner or other long object with cloth at the end of it. The cloth end will be used to wipe your windows down and remove any condensate that is left. This will help create a more secure seal and avoid the possibility of fogging in the future.
This is only temporary solution for 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.
