How to Repair Double Glazed Windows

Typically, double glazing comes with a guarantee of either 10 or 20 years. If your double-glazed windows are showing signs of aging, you could be eligible for them to be replaced under warranty.

Double-glazed window repairs require replacing the glass unit. Misting is a clear sign that the seal has failed and you need to have it fixed.

Glass damaged

A seal that is airtight is essential for double pane windows to function effectively. 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 fixed, but it's a sign that your glazing unit requires replacement. If you have an older double glazed window, this may mean replacing both the frame and the glass. If the frame is in good shape you might be able to save money by simply replacing the glass.

Glass is fragile, and it's not uncommon for double-pane windows to develop cracks over time. If the cracks weren't caused by mechanical damage, or an unusual impact on the window they can be fixed by using epoxy and elbow grease. Follow the instructions of the manufacturer and scrub the area of the crack using a wet cotton cloth. Then, apply epoxy to the crack. Allow the epoxy to completely dry before sanding and painting the repaired area.

It's also possible to prevent a crack from spreading with the use of a strip of masking tape. One strip of masking tape placed on the opposite side of the crack should suffice to stop superficial cracks from spreading, such as stress-cracks that are caused by low temperatures. If you're dealing with more severe cracks that have already formed in your glass, it could be better to contact a professional to ensure the security of the repair.

Attempting to replace just a single pane of double-pane windows is a difficult and dangerous DIY task. Double-paned windows are made as a unit and sealed with inert gases in the factory. Therefore, it is impossible to remove only the glass without damaging the window. If you're planning to replace the glazing in your double-pane windows, make sure you use a quality brand that is backed by a long-lasting warranty.

It's also an excellent idea to line the window frame with newspaper prior to when you attempt to take off the sash, and then replace any broken glass. This will help protect your from any sharp shards of glass that may fall during the process, and it'll also help to avoid any damage to the trim of your home or molding.

Condensation Build-Up

The good part is that condensation occurring between window panes is totally normal. It's due to a gap between the temperature of air and humidity levels that cause water vapour to condense upon contact with cold impenetrable surfaces such as windows. It's usually a good thing, especially in winter, as it can help prevent loss of heat.

If your windows appear cloudy and have a film of water on them, you should contact an experienced professional glazier. This indicates that the seal between the two panes is beginning to weaken 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 through drilling into the frame and injecting desiccant. This is a more complex procedure that requires the unit to be removed from the frame, allowing access to each pane of glass to clean them thoroughly, then filling them with desiccant and sealing them up. This is typically more expensive, however it's important to ensure that the company you select is insured and registered with FENSA.

Be aware that any modification to your double-glazed windows will end any warranties. If you have a warranty on your windows it's always recommended to let the company know of any issues that arise, as it will be accountable for the replacement of windows under warranty. It's best to consult an expert before undertaking any DIY repairs. This is especially true for older units as they can sometimes be more prone to fail. It is best to replace the entire glazed panel in case this happens. You'll then have brand new windows that will last for years.

Scratches

It's not unusual for double-glazed windows to be affected by scratches on their surfaces. This can be a result of environmental conditions or can even be caused by the way the window was originally installed.

Many of these scratches are minor and can be repaired by using a few home remedies. If you can feel the scratches on your windows with your fingernail, or when they are very deep, it is recommended to consult an expert to restore the glass to its original condition.

Superficial scratches result from objects scraping against the glass surface of your windows such as pet claws, tree branches and abrasive substances used for cleaning. These scratches are usually removed with non-abrasive solutions like iron oxide and cerium dioxide polishes. You will need to use these until the scratch disappears.

Scratches may also occur when you sand wood trim around your windows. They may also occur during construction. These scratches are often difficult to fix. However, a mix of baking soda and water will help smooth out the surface after buffing and eliminate any remaining scratches.

For deeper scratches you can apply a polishing metal to smooth the area and eliminate the marks. Add a small amount the product to a cotton ball or clean microfibre cloth and gently rub the affected area in a circular motion. Be careful not to apply too much pressure as this could exacerbate any further damage to the glass. After the area has been smoothed out then use a moist cloth to clean any polish residue left.

If you've got a deep scratch that you just can't get rid of, think about purchasing a non-abrasive glass polish. This can be bought at any DIY store and must be applied according to the instructions on the product packaging. Alternately, you can apply nail polish to smooth the area and cover any small scratches on the glass of your window. Make sure you apply the nail polish to the area that is scratched.

Haze

The presence of haze within your double-paned window means that the seal between the two panes has been damaged. This must be fixed as soon as you can so that dirt and moisture do not build up between the glass panes. This can cause damage to the glass and cause an increase in transparency.

There are a number of solutions to fix haze in your double pane windows. Make use of a defogging product. This is only a short-term solution. If you're looking for a long-lasting solution, you should consult a professional glass business. They can repair the issue or replace gaskets if needed.

Another method to eliminate haze in double glazed windows is to make small holes in the frame of the window using a carbide-tipped drill. You can then insert desiccate packs into these holes and wash the window with rubbing alcohol. The water will clear the haze and clean the window.

It's essential to keep your windows well maintained and regularly cleaned to prevent fogging. This will let you see through the double-panes and enjoy a beautiful view from your garden or home. Additionally, making sure that your home is ventilated is also beneficial. This will ensure that any condensation is quickly removed, instead of being allowed to settle and reseal the window.

In addition to regular maintenance and cleaning, you should also ensure that your windows are installed. The installation of your windows should be carried out by a reputable glazing company. This will ensure that the seals and gaskets are fitted properly, and fit tightly. It is also recommended to get your windows fixed as soon as you can, before they start to show signs of wear and tear. This will prevent expensive double pane window repairs.

In general, double-glazed windows with insulation are designed to last about 20 years. They are built to withstand different weather conditions such as extremely cold temperatures, high temperatures, humidity and repeated openings and closings. But, it is important to keep in mind that the typical life span of double-glazed windows can be diminished by inadequate installation or defective materials.
