How to Repair Double Glazed Windows

Typically, double glazing comes with a warranty of 10 or 20 years. If your double glazed windows are showing signs of ageing you may be entitled to have them fixed under warranty.

Double-glazed window repair involves replacing the seal on your existing glass. Misting is a clear sign that the seal is broken and you will need to get it repaired.

Damaged Glass

A seal that is airtight is vital for double pane windows to work properly. The most common sign that a seal is failing is the formation of condensation between the glass plates. While condensation between glass is not an issue that needs to be fixed, it's typically an indication that the glass unit is in need of replacement. If you have a double-glazed window that is old, it might be necessary to replace both the glass as well as the frame. If your frame is still in good condition it is possible to save money by only replacing the glass.

Double-paned windows can crack due to the brittleness of glass. Unless the cracks are caused by mechanical damage or a sudden impact, it's usually possible to repair these cracks using epoxy and little bit of elbow grease. Begin by cleaning over the area that is cracked with a damp 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.

It's also possible to keep cracks from spreading by using a simple strip of masking tape. One strip of tape placed on both sides of the cracked area is enough to prevent superficial cracks, such as stress cracks caused by low temperatures, from worsening. If you're dealing with more severe cracks that have already developed in your glass, it may be best to call a professional to ensure the safety of the repair.

It's risky and difficult to replace a single pane in a double-paned window. Double-pane windows are made as a complete unit and sealed at the factory using inert gas, so it would be impossible to remove the glass without damaging the entire window. If you are planning to replace the glass in your double-paned windows pick a manufacturer with an extensive warranty.

It's also a good idea to pad the window frame with newspaper before you attempt to remove the sash, and then replace any broken glass. This will protect you from any sharp shards that might fall in the process as well as to prevent any damage to the trim or molding of your home.

Condensation Build-Up

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

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

You can stop this by using dehumidifiers, improving ventilation, or by applying de-icing agents. There are companies that will remove excess moisture from double-glazed windows by drilling into the unit and injecting desiccant. This is a more complicated process that requires the sealed unit to be removed from the frame, opening up each glass pane, cleaning them thoroughly and then filling them with desiccant and sealing up again. This will usually be an expensive option, but it's worth checking that any firm you choose to use is insured and registered with FENSA.

Be aware that altering your double-glazed windows will invalidate any warranties. If you have windows that have a warranty it is recommended to inform the company of any issues since they will be responsible for any replacement units that are covered under warranty. It is recommended to speak with an expert before undertaking any DIY repairs. This is particularly relevant for older units since they can sometimes be more prone to failure. It is recommended to replace the entire glazed panel in case this happens. Then you'll have brand new windows that will last for many years to come.

Scratches

It is not uncommon for double glazed windows to be affected by scratches on their surfaces. This can be due to environmental factors, or the manner in which the window was constructed.

Most scratches are minor and can be fixed with some home solutions. If your windows have been scratched to the extent where you can feel them with your finger, it is best to seek out a professional for help to ensure that the glass surface is restored to its original form.

These scratches are caused when objects like tree branches, pet nails, and cleaning materials that are abrasive scrape against the glass of your windows. These scratches are usually removed using non-abrasive materials such as iron oxide or polishes made of cerium dioxide. You'll have to apply these products until the scratch disappears.

Scratches can also be caused by sanding the wood trim around your windows. They can also occur during construction work. These can be difficult to repair, however a small amount of baking soda and water can help smooth the area that has been buffed and remove any scratches that remain.

Metal polish can be used to remove deep scratches. Add a small amount to cotton balls or a clean microfibre towel, and gently rub the affected area in a circular motion. Avoid applying too much pressure as this can cause further damage to the window. Once the surface is smooth, use a damp cloth to wash away any remaining polish.

Think about purchasing a non-abrasive glass polish if you've got a an extremely deep scratch that you can't get rid of. This can be bought at any DIY store and must be applied in accordance with the instructions on the product packaging. You can also use nail polish to smooth the area and cover any shallow scratches on the glass of your window. Make sure you apply the nail polish to the area scratched.

Haze

The presence of haze within the double-paned windows indicates that the seal between the two panes is damaged. This needs to be fixed as soon as you can to ensure that moisture and dirt don't build up between the glass panes. This could damage the glass and decrease its transparency.

There are a variety of ways to eliminate haze from your double pane windows. One option is to apply a spray to defog the windows. However, this is only an interim solution. If you're looking for a permanent solution, you'll want to get in touch with a professional glazing business who can fix the issue and replace the gaskets if necessary.

A carbide-tipped tool can be used to make tiny holes in the window frame to remove haze. Then, you can insert a desiccate bag into these holes, and wash the window with rubbing-alcohol. The water will help remove the haze and cleanse the window.

To prevent fogging, you must maintain your windows and clean them frequently. This will let you look through the double panes and enjoy the stunning view from your home or garden. Additionally, making sure that your house is ventilated will also be beneficial. This will ensure that any condensation is quickly removed, instead of letting it sit and reseal your window.

It is not enough to clean and maintain your windows regularly However, you should also ensure that they're installed correctly. Installing windows should only be performed by a glazing company with years of experience. This will ensure that the gaskets and seals are installed correctly, and that they fit securely. It is a good idea to repair your windows as quickly as possible before they start showing signs of wear out. This will help avoid costly double pane windows repairs.

In general, double-glazed windows that have insulation are designed to last approximately 20 years. They are designed to stand up to different weather conditions such as extremely cold temperatures, high temperatures, humidity and repeated openings and closings. It is essential to be aware that an improper installation or defective material could reduce the life span of double-glazed windows.
