How to Repair Double Glazed Windows

Double glazing is usually covered by a warranty for 10 or 20 years. So, if your double-glazed windows are showing signs of ageing you may be eligible to have them repaired under warranty.

Double-glazed window repair requires replacing the seal on your existing glass. Misting is a clear indicator that the seal is broken and you will need to have it fixed.

Glass damaged

Double pane windows require an airtight seal in order to function effectively. Condensation between glass plates is a common indication of a failing seal. While condensation between glass isn't an issue that needs to be addressed, it's usually an indication that the glass unit is in need of replacement. If you have an older double glazed window, it could mean replacing both the frame and the glass. If your frame is in good condition however, you could generally save money by replacing only the glass.

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

It's also possible to keep a crack from spreading with an easy strip of masking tape. One strip of tape placed on both sides of the damaged area should be enough to stop superficial cracks, such as stress cracks caused by low temperatures, from worsening. If you have deeper cracks in your glass that are already present, it's recommended to consult a professional for the repair.

Attempting to replace just a single pane of double-pane glass is a risky and difficult DIY job. Double-paned windows are made as a complete unit and sealed with inert gases in the factory. Therefore, it is impossible to remove just the glass without damaging the window. If you intend to replace the glass in your double-paned windows, choose a brand with a strong warranty.

You can also use newspaper to shield the window frame prior to when you remove the sash or replace any broken glass. This will help protect you from any sharp shards that could fall on the way and also help to protect your home's trim or molding.

Condensation Build-Up

The good news is that condensation between windows is completely normal. It is caused by an imbalance in temperature and humidity of the air. The water vapour that is present in air is condensed when it comes into contact with cold, inaccessible surfaces such as windows. This is usually a good thing during winter because it prevents loss of heat.

If your windows appear cloudy and have a film of water on them, it is time to seek out 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 Repairs (Forum.Insnetz.Com).

You can stop this by using dehumidifiers, enhancing ventilation, or by applying de-icing agents. There are also companies that will remove excess moisture from double-glazed windows through drilling into the frame and injecting desiccant. This requires removal of the sealed unit from the frame and cleaning each glass pane before refilling the desiccant. This will usually be a more expensive option but it is worth checking whether the company you use is fully insured and is registered with FENSA.

It is important to keep in mind that tampering with double glazed windows is not advised and will invalidate any guarantees. If you have a warranty on your windows, it's recommended to let the company know of any issues that arise as it will be responsible for replacing units under warranty. It's best to consult an expert before attempting any DIY repairs. This is especially applicable to older units, because they're more likely than modern ones to fail. It is recommended to replace the entire glazed panel if this happens. The windows will then be brand new that will last for many years.

Scratches

Double-glazed windows aren't immune to scratches. This could be due to environmental factors, or even the manner in which the window was put in place.

Many of these scratches are not that severe and can be repaired with a few simple solutions. If your windows have been damaged to the point where you can feel the scratch with your finger it is recommended to seek out a professional for help to ensure that the glass is restored to its original state.

Most of the time, these scratches can be cleaned with some non-abrasive solutions such as iron oxide or cerium oxide polishes, which you will have to continue using until the scratch is gone.

Scratches can also be caused by sanding wood trim next to your windows. It can happen during construction work. These scratches can be difficult to fix. However, a mixture of baking soda and water will aid in smoothing out the surface that has been buffed and remove any remaining scratch.

Avoid applying too much pressure since this could cause damage to the window. After the area has been smoothed out, use a wet cloth to wash away any polish residue that remains.

Consider purchasing a non-abrasive special glass polish if you have an extremely deep scratch that you can't remove. It can be purchased at any DIY store and should be applied in accordance with the directions on the packaging. You can also use nail polish to smooth the area and cover any shallow scratches that your window glass may have. Be sure to only apply the nail polish only to the area scuffed.

Haze

The appearance of fog in your double-pane window is a sign that the airtight seal between the two panes of glass has been damaged. This needs to be fixed immediately so that moisture and dirt don't build up between the glass panes. This could cause damage to the glass and reduce its transparency.
