How to Repair Double Glazed Windows
Double glazing is usually covered by a guarantee of 10 or 20 years. If your double-glazed windows are showing signs of aging you may be entitled to have them repaired under warranty.
Double glazed
window repair involves replacing the seal on your existing glass. The misting is a clear indication that the seal is broken and you will need to repair it.
Glass that is damaged
A seal that is airtight is crucial for double pane windows to function properly. The most common sign that a seal is failing is condensation forming between the glass plates. While condensation between glass is not an issue that is serious and can be addressed, it's usually a sign that the glazing unit requires replacement. If you have a double-glazed window that is older, it may be necessary to replace the glass as well as the frame. If your frame is in good condition you might be able to save money by only replacing the glass.
Double-paned windows may develop cracks because of the fragility of glass. If the cracks aren't caused by mechanical damage or an unusual impact on the
window repair, they can be repaired with epoxy and some elbow grease. Begin by cleaning over the cracked area with a wet cotton rag. Then, apply epoxy to the crack following the manufacturer's instructions. Allow the epoxy to dry completely before sanding and painting over the repaired area.
It's also possible to keep a crack from spreading with an easy strip of masking tape. A single strip of tape on both sides of the cracked area is enough to keep superficial cracks, like stress cracks caused by low temperatures, from getting worse. If you notice more severe cracks in your glass that are already present, it's recommended to consult a professional for the repair.
It's risky and difficult to replace a single pane in a double-paned window. Double-paned windows are manufactured as a whole unit and sealed with inert gases in the factory. It is therefore impossible to remove just the glass without damaging the window. If you plan to replace the glass in your double-pane windows, make sure you choose a reputable brand with a strong warranty.
It's also recommended to cover the window frame with newspaper before you attempt to take off the sash, and then replace any broken glass. This will shield your from any glass shards with sharp edges that might fall during the process. It also protects against any damage to the molding or trim of your home.
Condensation Build-Up
It's important to understand that condensation between the window panes can be completely normal. It's due to a gap between the temperature of air and humidity levels that cause water vapour to condense when it touches cold impenetrable surfaces such as windows. This is usually beneficial, especially during winter because it can help prevent heat loss.
If your windows appear cloudy and have a layer of water on them, you must contact a professional glazier. This is an indication that the air gap seal between the two panes of glass is beginning to break down and is allowing moisture to enter the window.
You can stop this from happening by making use of dehumidifiers, increasing ventilation, or applying de-icing agents. Alternatively, there are several professional companies that can help fix condensation build-up in double glazed windows by drilling holes in the window and then injecting or pumping a special desiccant to remove the excess moisture. This involves removal of the sealed unit from the frame and cleaning each glass pane before refilling the desiccant. This will usually be an expensive option, but it is worth checking whether the firm you choose to use is insured and is registered with FENSA.
Be aware that any modification to your double-glazed windows can end any warranties. If you have windows that have a warranty, it is best to inform the company of any issues as they will be responsible for any replacement units that are covered under warranty. It's best to consult an expert before undertaking any DIY repairs. This is especially true for older units as they are sometimes more prone to fail. It is best to replace the entire glazed panel if this happens. Then you'll have brand new windows that will last for many years to come.
Scratches
It's not unusual for double-glazed windows to be affected by scratches to their surface. This could be the result of environmental factors or could be caused by the manner the window was installed.
Thankfully, most of these scratches are minor and can be repaired with some do-it-yourself home remedies. If you can feel the scratches on your windows with your fingernail or when they are very deep, you should consult a professional to restore the glass to its original condition.
Superficial scratches are caused by objects scraping against the glass the windows' surface, such as tree branches, pet claws and abrasive substances used for cleaning. Usually, scratches can be cleaned with certain non-abrasive products like iron oxide or cerium oxide polishes which you'll need to continue using until the scratch is not visible anymore.
Scratches can also be caused by sanding wood trim next to your windows and may occur during construction work. These scratches may be difficult to fix. However, a mix of baking soda and water can help smooth out the buffed surface and remove any remaining scratch.
For deeper scratches you can use a polishing metal to smooth the area and eliminate them. Apply a small amount to a cotton ball, or a clean microfibre towel, and gently rub the area in a circular manner. Be careful not to apply too much pressure as this can cause further damage to the window. After the area has been smoothed out, use a wet cloth to remove any polish residue that remains.
If you've got a particularly deep scratch that you just can't seem to remove, consider purchasing a non-abrasive glass polish. It is available at any DIY store. Follow the instructions on the package. You can also use nail polish to cover any superficial scratches on the window glass. Ensure that the nail polish is clear and is only applied to the scuffed part of your window.
Haze
The presence of haze within your double-paned window means that the seal between the two panes has been damaged. It's crucial to get this repaired as soon as you can so that you don't end with dirt and moisture build-up between the panes. This can damage the glass and reduce its transparency.
There are many options to remove the haze on your double paned windows. Make use of a defogging product. However, this is just a temporary solution. If you're looking for a permanent solution, contact a professional glazing company that can repair the problem and replace the gaskets if necessary.
Another method to eliminate the problem of haze on double-glazed windows is to drill tiny holes into the window frame, using a carbide-tipped drill. You can then insert desiccate packs into these holes and wash the window using rubbing alcohol. The water will help to rid the haze and cleanse the window.
It's essential to keep your windows well maintained and cleaned regularly to avoid fogging. This will allow you to see through the double panes and enjoy a stunning view from your home or garden. In addition, ensuring that your home is ventilated will also be beneficial. This will ensure that any condensation is quickly removed, rather than allowing it to settle and reseal the window.
It is important to not just clean and maintain your windows frequently, but also ensure that they are installed correctly. Installing your windows should only be done by a glazing company with expertise. This will ensure that the seals and gaskets are fitted correctly, and that they fit tightly. It's a good idea repair your windows as quickly as possible before they start showing signs of wear out.
