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 aging, you may be entitled to have them fixed under warranty.
Double glazed window repair involves re-sealing your existing glass unit. The seal isn't working properly when you notice misting.
Damaged Glass
A seal that is airtight is vital for double pane windows to work properly. Condensation between glass plates is a typical indication of a failing seal. While condensation between glass is not an issue that is serious and can be addressed, it's usually an indication that the glazing unit requires replacement. If you have a double-glazed window that is older, it may be necessary to replace both the glass as well as the frame. If your frame is in good shape however, you could usually save money by replacing only the glazing.
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 it is possible to repair them with epoxy and some elbow grease. Follow the manufacturer's instructions and scrub the crack with a moist cotton cloth. Then apply the epoxy to the crack. Allow the epoxy to dry completely before sanding it down and painting over the repaired area.
A simple strip of masking tap can be used to keep cracks from spreading. A single strip of masking tape on the opposite side of the crack should suffice to stop superficial cracks from spreading, for instance stress-cracks that are caused by low temperatures. If you have deeper cracks in your glass that are already present, it's recommended to consult a professional for the repair.
It's risky and difficult to replace a single pane of a double-paned window. 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 are planning to replace the glass in your double-paned windows, choose a brand with a long-lasting warranty.
It's also an excellent idea to line 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 your home's trim or molding.
Condensation Build-Up
It's good to know that condensation on windows can be normal. This is due to the difference in humidity and temperature of the air. The water vapour in air condenses when it comes in contact with cold, inaccessible surfaces such as windows. This is usually a great thing in winter, as it stops the loss of heat.
If you notice that your windows are appearing cloudy and have a layer of moisture on them, it's time to hire a professional glazier. This is a sign that the 'air gap seal between two panes of glass has begun to weaken and allowing moisture into the window.
You can attempt to stop this from happening by using a dehumidifier, improving ventilation or using a deicing agent. There are companies that can remove excess moisture from double-glazed windows through drilling into the unit and injecting desiccant. This is a more complex process that requires the sealed unit to be removed from the frame, and then opening each pane of glass, cleaning them thoroughly and then filling them with desiccant and sealing them up. This is usually more expensive However, it's crucial to check that the company you choose to work with is insured and registered with FENSA.
Be aware that any modification to your double-glazed windows can invalidate any warranties. If you have windows that are covered by a warranty it is recommended to inform the company of any issues since they'll be responsible for any replacement units that are covered under warranty. Additionally, any damage that is caused by tampering is likely not be covered under your warranty either, so it is recommended to seek expert advice before trying any DIY repair. This is especially applicable to older units as they can sometimes be more prone to fail. It's best to replace the entire glass panel in case this happens. This way, you'll have brand-new windows that will last for many years.
Scratches
It's not uncommon for double glazed windows to be impacted by scratches on their surfaces. This could be due to environmental factors, or even the manner in which the window was put in place.
Fortunately, the majority of these scratches are superficial and can be easily repaired by a few do-it-yourself remedies. If you feel scratches on your windows using your fingernail, or if they are deep, it's best to consult a professional to repair the glass to its original condition.
Superficial scratches result from objects scraping against the glass the windows' surface such as tree branches, pet claws and abrasive substances used for cleaning. Usually, scratches can be eliminated using some non-abrasive solutions like iron oxide polishes or cerium oxide, but you'll need to continue using until the scratch is gone.
Scratches can also happen when you sand wood trim around your windows. They can also happen during construction. These can be difficult to repair, however a little bit of baking soda mixed with water can help smooth the buffed area and remove any scratches that remain.
For more severe scratches you can apply a polish for metal to smooth the area and remove 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 cautious not to apply too much pressure, as this could exacerbate any damage to the glass. Once the area is smooth, use a damp cloth to wash away any excess polish residue.
If you have a particularly deep scratch that you cannot remove, you should consider buying a special non-abrasive glass polish. It can be purchased at any DIY store and should be applied following the instructions on the product packaging. Alternatively, you can use nail polish to smooth the area and cover any shallow scratches that your window glass may have. Ensure that the nail polish is clean and that it is only applied to the scuffed area of your window.
Haze
The presence of haze in the double-paned windows indicates that the seal between the two panes has been damaged. It's crucial to get this fixed as soon as possible to ensure that you don't end having dirt and moisture build-up between the panes. This could damage the glass and decrease its transparency.
There are a variety of options to remove haze from your double pane windows. Make use of a defogging product. However, this is just a temporary solution. If you're looking for a lasting solution, you'll need to seek out a professional glazing company who can fix the issue and replace the gaskets if necessary.
A carbide-tipped tool can be used to make tiny holes into the frame of the window to eliminate haze. You can then insert the desiccate packet inside these holes and then wash the window with ruby alcohol. The water will clear the haze as well as clean the window.
It's essential to keep your windows well maintained and cleaned regularly to avoid fogging. This will keep your double panes clear and allow you to take in the stunning view of your garden or home. Also, ensuring that your home is well ventilated is also beneficial. This will ensure that any condensation is swiftly removed, instead of letting it settle and then reseal your window.
It is important to not just clean and maintain your windows on a regular basis However, you should also ensure that they are properly installed. The installation of your windows must be done by a professional glazing company. This will ensure that the gaskets and seals are installed correctly, and that they fit tightly. It's also a good idea to have your windows repaired as quickly as possible, before they start to show signs of wear and tear. This will help to avoid costly double pane window repairs .
In general, double glazed insulated windows are built to last around 20 years. This is because they are built to withstand various weather conditions, including very cold temperatures, extreme humidity, heat as well as repeated closing and opening. It is crucial to remember that faulty installation or materials can decrease the life span of double-glazed windows.
