How to Repair Double Glazed Windows
Typically double glazing comes with a guarantee of either 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 involves replacing the seal on your existing glass. The seal isn't working properly in the event that you see misting.
Glass damaged
Double pane windows depend on an airtight seal to function correctly. The condensation between the glass plates is a common sign of a failing seal. While condensation between glass is not an issue that needs to be addressed, it's usually a sign that the glazing unit needs to be replaced. If you have an older double glazed window, this may mean replacing both the glass and the frame. If the frame is in good condition, however, you can generally save money by replacing only the glass.
Glass is brittle, and it's not uncommon for double-pane windows to crack as time passes. Unless the cracks are caused by mechanical damage or a sudden impact, it's usually possible to repair the cracks using epoxy and a small amount of elbow grease. Start by cleaning over the crack using a moist cotton rag. Then, apply epoxy to the crack, according to the instructions of the manufacturer. Allow the epoxy to completely dry before sanding and painting over the repaired area.
It's also possible to prevent cracks from spreading by using a simple strip of masking tape. One strip of masking tape applied to the opposite side of the crack should be sufficient to prevent superficial cracks from spreading, for instance stress-cracks caused by low temperatures. If you're dealing more serious cracks that have already formed in your glass, it might be better to contact an expert to ensure the safety of the repair.
Removing a single pane of double-pane window glass is a risky and difficult DIY task. Double-paned windows are made as a whole unit and sealed with inert gases in the factory. It is therefore impossible to take off just the glass without damaging the window. If you plan to replace the glass in your double-paned windows choose a brand with a long-lasting 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 help protect you from any glass shards with sharp edges that might fall during the process. It also protects against any damage to the molding or trim of your home.
Condensation Build-Up
It's good to know that condensation in the windows can be normal. This is due to the difference in humidity and temperature of the air. The water vapour that is present in air condenses when it comes in contact with cold, inaccessible surfaces like windows. This is generally a good thing during winter, since it helps prevent the loss of heat.
However, if you're noticing that your windows are appearing cloudy and have a layer of water on them, it's probably time to hire an expert glazier. This is an indication that the air gap seal between two glass panes has begun to weaken and is allowing moisture to enter the window.
You can stop this from happening 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 into the window and pumping or injecting a specific desiccant to eliminate the excess moisture. This involves removal of the sealed unit from the frame and then cleaning each glass pane before refilling the desiccant. This is usually more expensive However, it's crucial to make sure the company you choose to work with is licensed and insured with FENSA.
It's important to remember that tampering with your double-glazed windows isn't advised and could end any guarantees. If you have a warranty on your windows, it is best to inform the company of any problems as they'll be accountable for any replacement units that are covered under warranty. It is recommended to speak with an expert before attempting any DIY repairs. This is particularly the case for older units as they are sometimes more likely than modern ones to fail. If this happens, it's best to replace the whole glazed panel. This way, you'll have brand-new windows that will last for many years.
Scratches
It's not unusual for double-glazed windows to be affected by scratches on their surfaces. This can be due to environmental factors, or even the way in which the window was installed.
Thankfully, most of these scratches are minor and can be repaired by a few do-it-yourself remedies. If you can feel the scratches on your windows with your finger or nail, or If they're deep, it is recommended to consult a professional to restore the glass to its original state.
These scratches are caused by objects such as tree branches, pet nails and cleaning products which are abrasive rub against the glass of your windows. The scratches can be removed by using non-abrasive products like iron oxide and polishes made of cerium dioxide. You'll have to apply these products until the scratch disappears.
Scratches can also happen when you sand wood trim around your windows. They may also occur in the course of construction. These scratches can be difficult to fix. However, a mixture of baking soda and water can help smooth out the buffed surface and remove any remaining scratches.
For deeper scratches you can use a metal polish to smooth the area and remove them. Apply a small amount the product to a microfibre or cotton cloth and gently rub over the affected area in a circular motion. Avoid applying too much pressure since this could cause damage to the window. Once the area is smooth, use a moist cloth to remove any excess polish residue.
If you've got a particularly deep scratch that you cannot seem to remove, consider buying a special non-abrasive glass polish. This is available at any DIY store and should 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 that your window glass may have. Make sure that the nail polish is clear and only applied to the scratched part of your window.
Haze
The presence of haze in your double-paned window indicates that the seal between the two panes is damaged. This must be fixed as soon as possible to ensure that moisture and dirt are not able to accumulate between the glass panes. This can damage the glass and reduce its transparency.
There are many options to remove the haze on double pane windows. Make use of a defogging product. However, this is only an interim solution. If you're looking for a lasting solution, contact a professional glazing company who can fix the issue and replace the gaskets if necessary.
A carbide-tipped tool can be used to drill tiny holes into the window frame to remove haze. You can then insert a desiccate bag into these holes, and then wash the window with rubbing alcohol. The water will clear the haze as well as clean the window.
To prevent fogging, it is essential to keep your windows clean and maintained by cleaning them on a regular basis. This will let you see through the double panes and enjoy the stunning view from your home or garden. Also, ensuring that your home is ventilated can also be beneficial. This will ensure that any condensation is quickly removed, rather than allowing it to settle and reseal the window.
It is important to not just clean and maintain your windows regularly However, you should also ensure that they are installed correctly. The installation of your windows should be carried out by a reputable glazing company. This will help to ensure that the gaskets are installed properly and have a tight fit.

In general, double-glazed windows that have insulation are designed to last approximately 20 years. This is due to the fact that they are built to withstand all kinds of weather conditions, including very cold temperatures, extreme humidity, heat and frequent closing and opening. It is crucial to remember that improper installation or faulty material could reduce the life span of double-glazed windows.
