How to Repair Double Glazed Windows

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

Double-glazed window repair requires re-sealing your existing glass unit. The seal isn't working properly if you see mist.

Damaged Glass

Double pane windows depend on an airtight seal in order to perform effectively. The most typical sign that a seal is failing is the formation of condensation between the glass plates. Condensation between glass plates is not a major issue and can be fixed however, it's a sign that your glazing unit needs replacing. If you have an older double-glazed window, it could require replacing both the frame and the glass. If your frame is in good shape, you may be able to save money by only replacing the glass.

Glass is brittle, and it's not uncommon for double-pane windows to develop cracks as time passes. If the cracks were not caused by mechanical damage or a jarring impact to the window it is possible to repair them with epoxy and some elbow grease. Start by cleaning over the crack using a moist cotton rag. Then, apply epoxy to the crack following the manufacturer's instructions. Allow the epoxy to fully dry before sanding and painting over the repaired area.

A simple strip of masking tape can also be used to stop a crack from spreading. One strip of masking tape applied to both sides of the crack ought to suffice to stop cracks that appear superficial from spreading, such as stress-cracks caused by low temperatures. However, if you're dealing more serious cracks that are already forming in your glass, it could be best to call an expert to ensure the safety of the repair.

It is dangerous and difficult to replace a single pane within a double-paned window. Double-paned windows are manufactured as a complete unit and sealed with inert gas in the factory. It is therefore impossible to remove just the glass without damaging the window. If you are planning to replace the glass in your double-paned windows, choose a brand with a long-lasting warranty.

It's also recommended to cover the window frame with newspaper before you attempt to remove the sash and replace any damaged glass. This will protect your from any glass shards that could fall in the process. It also protects against any damage to the trim or molding of your home.

Condensation Build-Up

The good news is that condensation between window panes is totally normal. It's caused by a disparity between air temperature and humidity levels and causes water vapour to condense when it touches cold impenetrable surfaces such as windows. This is usually a good thing in winter, as it stops loss of heat.

However, if you're finding that your windows are looking like they're cloudy, with a film of moisture on them, it's probably time to call in an experienced glazier. This is an indication that the air gap' seal between the two panes of glass has begun to weaken and is letting moisture into the window.

You can stop this by using dehumidifiers, improving ventilation, or applying de-icing agents. Additionally, there are professional companies that can help solve condensation issues in double-glazed windows by drilling holes into the window unit and then injecting or pumping a special desiccant to eliminate the excess moisture. This involves removing the sealed unit from the frame and then cleaning each glass pane before refilling the desiccant. This is usually an expensive option, but it is worth checking whether the company you select is insured and registered with FENSA.

Be aware that altering your double-glazed windows can cause the windows to be void of any warranties. If you have a guarantee on your windows it's always recommended to let the company know of any issues that arise since they will be responsible for replacing units under warranty. It's best to consult an expert before undertaking any DIY repairs. This is particularly relevant for older units since they are sometimes more prone to fail. It's best to replace the entire glazed panel in the event of this. You'll then have brand-new windows that will last many years.

Scratches

It's not unusual for double glazed windows to be affected by scratches on their surface. This could be the result of environmental conditions or could be caused by the manner the window was installed.

These scratches happen when objects like pet nails, tree branches, and cleaning materials which are abrasive rub against the glass of your windows. These scratches are usually removed using non-abrasive materials like iron oxide or cerium dioxide polishes. You will require these products until the scratch disappears.

Scratches can also be caused by sanding the wood trim next to your windows. They can also occur during construction work. These scratches are often difficult for you to repair. However, a mixture of baking soda and water can aid in smoothing the buffed surface and remove any remaining scratch.

For deeper scratches you can use a metal polish to smooth the area and remove them. Add a small amount of it to cotton balls, or a clean microfibre towel and gently rub the area with a circular motion. Be cautious not to apply too much pressure, as this can cause damage to the glass. After the area has been smoothed out, use a wet cloth to wash away any polish residue that remains.

Think about purchasing a non-abrasive glass polish if you've got a an extremely deep scratch that you can't remove. It is available at any DIY retailer. Follow the instructions on the package. Alternately, you can apply nail polish to smooth the area and cover any shallow scratches that your window glass may have. Make sure that the nail polish is clean and that it is only applied to the scuffed area of your window.
