How to Repair Double Glazed Windows

Double glazing is typically covered by a guarantee of 10 or 20 year. If your double-glazed windows are showing signs of aging you could be eligible to have them fixed under warranty.

Double glazed window repair involves the re-sealing of your glass unit. The seal is failing when you notice misting.

Damaged Glass

Double pane windows depend on an airtight seal in order to work properly. Condensation between the glass plates is a typical sign of a failing seal. Condensation that forms between glass plates is not a major issue and can be resolved, but it's an indication that your glazing unit requires replacement. If you have an older double-glazed window, this could mean replacing both the glass and the frame. If the frame is in good condition you might be able to save money by only replacing the glass.

Double-paned windows may develop cracks due to the brittleness of glass. If the cracks aren't caused by mechanical damage or a jarring impact to the window they can be fixed with epoxy and some elbow grease. Follow the manufacturer's instructions and scrub the area of the crack with a moist cotton cloth. Then apply the epoxy to the crack. Allow the epoxy to dry completely before sanding down and painting over the repaired area.

It's also possible to keep cracks from spreading with the use of a strip of masking tape. One strip of tape placed on both sides of the crack area is enough to prevent superficial cracks, like stress cracks that result from low temperatures, from getting worse. If you have deeper cracks in your glass that are already present, it is recommended to consult an expert to repair the damage.

It is risky and difficult to replace a single pane within a double-paned window. Double-pane windows are constructed as a complete unit and sealed in the factory with inert gas. Therefore, it is impossible to remove the glass without damaging the entire window. If you intend to replace the glass in your double-paned windows, select a brand that has an extensive warranty.

You can also use newspaper to shield the window frame before you remove the sash or replace any broken glass. This will protect your from any glass shards that might fall during the process. It will also prevent any damage to the trim or molding of your home.

Condensation Build-Up

It's important to understand that condensation on window panes can be completely normal. This is caused by the difference in humidity and temperature of the air. The water vapour in air is condensed when it comes into contact with cold, impenetrable surfaces like windows. This is usually a great thing during winter because it prevents heat loss.

However, if you're finding that your windows are appearing cloudy with a film of water on them, it's probably time to call in an experienced glazier. This is a sign that the seal between the two panes is beginning to degrade and allows moisture to enter the window.

You can stop this from happening by using dehumidifiers, enhancing ventilation, or applying de-icing agents. There are companies that can eliminate excess moisture from double-glazed windows by drilling into the unit and injecting desiccant. This is a more complex procedure that requires the sealed unit to be removed from the frame, allowing access to each pane of glass, cleaning them thoroughly and then filling them with desiccant prior to sealing up again. This is usually an expensive option however, it's essential to ensure that the company you choose to work with is insured and is registered with FENSA.

Be aware that altering your double-glazed windows can end any warranties. If you have a warranty on your windows, it's recommended to let the company know about any problems that arise, as it will be accountable for the replacement of units covered under warranty. It's best to consult an expert prior to undertaking any DIY repairs. This is particularly applicable to older units, because they're more prone to fail. It is best to replace the entire glass panel in case this happens. Then you'll have brand new windows that will last for years to come.

Scratches

Double-glazed windows are not resistant to scratches. This can be due to environmental factors, or the way in which the window was put in place.

Many of these scratches are superficial, and can be repaired with a few simple solutions. If you can feel the scratches on your windows with your fingernail, or If they're deep, it is recommended to consult an expert to restore the glass to its original state.

Superficial scratches result from objects scraping against the glass surfaces of your windows such as pet claws, tree branches and abrasive substances used for cleaning. The scratches can be removed with non-abrasive solutions such as iron oxide or cerium dioxide polishes. You'll have to apply these products until the scratch disappears.

Scratches can also occur while finishing sanding wood trim close to your windows. They can also happen in the course of construction. These scratches may be difficult to repair. However, a mix of baking soda and water will help smooth out the buffed surface and remove any remaining scratches.

For more severe scratches you can apply a polishing metal to smooth the area and eliminate scratches. Add a small amount of the product to a microfibre ball or cotton cloth and gently rub over the affected area in an upward motion. Be careful not to apply too much pressure as this could exacerbate any further damage to the glass. Once the surface is smoothed, use a moist cloth to remove any polish residue.

You may want to consider purchasing a non-abrasive glass polish if you've got a an incredibly deep scratch that you cannot seem to remove. You can purchase this at any DIY retailer. Follow the directions on the package. Alternately, you can apply nail polish to smooth the area and cover any shallow scratches on the glass of your window. Make sure that the nail polish is clear and that it is only applied to the scratched part of your window.

Haze

The presence of haze in your double pane window indicates that the airtight seal between the two panes of glass has been damaged. This must be fixed immediately to ensure that moisture and dirt do not build up between the glass panes. This can cause damage to the glass and result in an increase in transparency.

There are many solutions to fix haze in your double pane 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 who can fix the issue and replace the gaskets if needed.

Another way to solve haze in double glazed windows is to drill small holes into the frame of the window, using a carbide-tipped drill. Then, you can insert desiccate packs into these holes, and then wash the window using rubbing alcohol. The water will help remove the haze off the window and clean it.

To prevent fogging, you must maintain your windows and clean them frequently. This will allow you to see through the double-panes and enjoy a beautiful view from your home or garden. Additionally, making sure that your home is ventilated can also be beneficial. This will ensure that any condensation is quickly removed, and not allowing it to settle and then reseal your window.

In addition to regular cleaning and maintenance, you should also make sure that your windows are correctly installed. The installation of your windows should be handled by an experienced glazing company. This will ensure that the seals and gaskets are installed properly, and fit securely. It is also a good idea to have your windows repaired as quickly as you can, before they begin to exhibit signs of wear and tear. This will save you from costly double pane window repairs.

In general, double-glazed windows that have insulation are designed to last approximately 20 years. They are designed to stand up to various weather conditions, including very cold temperatures, heat and humidity as well as frequent openings and closings. But, it is crucial to keep in mind that the time-to-life of double-glazed windows may be reduced by improper installation or faulty materials.
