How to Repair Double Glazed Windows

Typically double glazing comes with a warranty of 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 repairs involve resealing the glass unit. Misting is a clear sign 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 work effectively. Condensation between the glass plates is a typical sign of a faulty seal. While condensation between glass is not a serious problem and can be dealt with, it's typically an indication that the glass unit needs to be replaced. If you have an older double-glazed window, this could mean replacing both the frame and the glass. If your frame is in good condition you might 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. Unless the cracks are caused by mechanical damage or an unusual impact, it's possible to repair the cracks using epoxy and a small amount of elbow grease. Begin by cleaning over the cracked area using a moist cotton rag and then apply epoxy to the crack, following the instructions of the manufacturer. Allow the epoxy to completely dry before sanding it down and painting over the repaired area.

A simple strip of masking tap can also be used to stop cracks from spreading. One strip of tape on both sides of the crack area is enough to stop superficial cracks, like stress cracks caused by low temperatures, from worsening. If you're dealing with deeper cracks that have already formed in your glass, it could be best to call a professional to ensure the safety of the repair.

It is dangerous and difficult to replace a single pane in double-paned windows. Double-paned windows are made as a whole unit and sealed with inert gases in the factory. It is therefore impossible to remove just the glass without damaging the window. If you plan to replace the glass in your double-paned windows, select a brand that has a strong warranty.

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

Condensation Build-Up

The good news is that condensation between windows is completely normal. This is caused by an imbalance in humidity and temperature of the air. The water vapour in air condenses when it comes into contact with cold, impenetrable surfaces such as windows. This is generally a good thing in winter, as it stops loss of heat.

If your windows look cloudy and have a layer of water on them, it is time to contact an experienced professional glazier. This is an indication that the seal between the two panes is beginning to degrade and allows moisture to enter the window.

You can stop this by making use of a dehumidifier, increasing ventilation, or using a de-icing agent. Additionally, there are specialist companies who will repair condensation build-up in double glazed windows by drilling holes in the window and pumping or injecting a specific desiccant to remove the excess moisture. This is a more complex procedure that requires the unit to be removed from the frame, and then opening each pane of glass and thoroughly cleaning them, then refilling with desiccant before sealing them up. This is usually a more expensive option but it's worth checking that any firm you choose to use is insured and is registered with FENSA.

Be aware that any modification to your double-glazed windows can end any warranties. If you have a warranty on your windows it is recommended to notify the manufacturer of any problems as they'll be accountable for replacement units under warranty. It is recommended to speak with an expert before attempting any DIY repairs. This is particularly true for older units as they can sometimes be more susceptible to failure. It is best to replace the entire glass panel if this happens. The result will be brand new windows that will last for a long time.

Scratches

It is not uncommon for double glazed windows to be affected by scratches on their surface. This could be due to environmental factors, or the way the window was constructed.

A majority of scratches are superficial, and can be fixed with a few simple remedies. If your windows have been scratched to the extent where you can feel the scratch with your finger it is recommended to consult a professional to ensure that the glass surface is restored to its original form.

Superficial scratches result from objects scraping against the glass surfaces of your windows such as tree branches, pet claws and fitted abrasive materials utilized when cleaning. These scratches can often be removed using non-abrasive materials like iron oxide or polishes made of cerium dioxide. You'll require these products until the scratch disappears.

Scratches can also be caused by sanding wood trim around your windows and may occur during construction work. They can be difficult to door repair, but the use of baking soda mixed with water can help smooth the area that has been buffed and remove any remaining scratches.

Metal polish can be used to remove more severe scratches. Add a small amount to cotton balls or a clean microfibre cloth and gently rub the 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 glass has been smoothed, use a damp cloth to wash away any polish residue.

If you've got a deep scratch that you just can't remove, you should consider purchasing a non-abrasive glass polish. You can buy this at any DIY retailer. Follow the instructions on the packaging. You can also use nail polish to cover any scratches on the window glass. Make sure that you only apply the nail polish only to the area that is scuffed.

Haze

The presence of haze in your double pane window is an indication that the airtight seal between the two panes of glass has deteriorated. It is essential to get this repaired quickly to ensure that you don't end up with moisture and dirt build-up between the panes. This could damage the glass and decrease its transparency.

There are many ways to eliminate haze from your double pane windows. Use a defogging agent. But, this is only an interim solution. If you're looking for a lasting solution, you'll want to get in touch with a professional glazing business that can fix the issue and replace the gaskets if needed.

Another method to eliminate the problem of haze in double-glazed windows is to make small holes in the frame of the window using a carbide-tipped drill. You can then put desiccate packs into these holes, and wash the window with rubbing alcohol. The water will help remove the haze off the window and cleanse it.

To avoid fogging, it's important to maintain your windows and clean them on a regular basis. This will keep the double panes clear and allow you to take in the stunning view of your backyard or home. Also, ensuring that your home is well ventilated is also beneficial. This will ensure that any condensation gets eliminated, rather than being allowed to settle and reseal the window.

In addition to the regular cleaning and maintenance You should also make sure that your windows are installed. Installing your windows should only be performed by a glass company with years of experience. This will ensure that the seals and gaskets are fitted correctly, and that they fit securely. It's also a good idea to have your windows repaired as quickly as you can before they start to begin to show signs of wear and tear. This will save you from costly double pane window repairs.

In general, double-glazed windows with insulation are built to last for about 20 years. This is because they are built to withstand various weather conditions, such as extremely cold temperatures, extreme humidity, fitted heat as well as repeated opening and closing. It is crucial to keep in mind that an improper installation or defective material could reduce the life span of double-glazed windows.
