How to Repair Double Glazed Windows
Typically, double glazing comes with a guarantee of 10 or 20 years. If your double glazed windows are showing signs of aging you could be eligible to have them fixed under warranty.
Double-glazed window repairs require replacing the glass unit that is in use. The seal isn't working properly when you notice misting.
Glass that is damaged
A seal that is airtight is vital for double pane windows to function properly. The most frequent sign that a seal is not working is when condensation forms between the glass plates. Condensation between glass plates is not a major problem and can be fixed however, it's a sign that your glazing unit needs replacing. If you have a double-glazed window that is older, it could be necessary to replace the glass and the frame. If your frame is in good condition, however, you can generally save money by replacing just the glass.
Double-paned windows can crack due to the brittleness of glass. 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. Begin by cleaning the cracked area 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.
A simple strip of masking tap can also be used to prevent a crack from spreading. One strip of tape placed on both sides of the cracked area should be enough to prevent superficial cracks, like stress cracks caused by low temperatures, from worsening. If you notice more severe cracks in your glass that are already present, it is recommended to consult an expert for repair.
It is risky and difficult to replace a single pane of double-paned windows. Double-pane windows are made as a complete unit, and sealed in the factory using inert gas. Therefore, it is impossible to remove the glass without causing damage to the entire window. If you're planning to replace glass in your double pane windows, make sure you select a high-quality brand that is backed by a long-lasting warranty.
It's also a good idea to pad the window frame with newspaper before you attempt to take off the sash, and then replace any broken glass. This will shield you from any sharp glass shards which may fall during the process. It also helps prevent any damage to the trim or molding of your home.
Condensation Build-Up
The good news is that condensation between windows is completely normal. It's caused by a difference between the temperature of the air and humidity levels that cause water vapour in the air to condense when it touches cold and impervious surfaces like windows. This is usually a good thing in winter, as it helps prevent loss of heat.
However, if you're finding that your windows are looking like they're cloudy, with a film of moisture on them, it's time to call in an expert Glazier. This is an indication that the air gap seal between the two panes of glass has begun to weaken and is allowing moisture to enter the window.
You can stop this from happening by using dehumidifiers, enhancing ventilation, or by applying de-icing agents. Alternatively, there are several professional companies that can help repair condensation build-up in double glazed windows by drilling holes into the window and injecting or pumping special desiccant in order to eliminate the excess moisture. This requires removing the sealed unit from the frame and then cleaning each pane of the glass before refilling the desiccant. This is usually a more expensive solution however, it's essential to make sure the company you choose is licensed and insured with FENSA.
It's important to remember that altering your double-glazed windows isn't recommended and could invalidate any guarantees. If you have a warranty on your windows it's always recommended to let the company be aware of any issues that arise as it will be accountable for the replacement of windows under warranty. Also, any damage incurred through tampering will likely not be covered by your warranty, so it's better to seek advice from a professional before trying any DIY repairs. This is particularly applicable to older units, since they're often more likely than modern ones to fail. If this happens, it's probably best to replace the whole glazed panel. The result will be brand new windows that will last many years.
Scratches
It is not uncommon for double glazed windows to be affected by scratches to their surface. This can be a result of environmental factors or even caused by the manner in which the window was originally installed.
Many of these scratches are minor and can be easily fixed by using a few home remedies. If your windows have been damaged to the point where you can feel the scratch with your finger, it is best to consult a professional to ensure that the glass is restored to its original state.
Superficial scratches are caused by objects that scrape against the glass surface of your windows such as pet claws, tree branches and abrasive substances used for cleaning. These scratches are usually removed using non-abrasive materials like iron oxide and polishes made of cerium dioxide. You will have to apply these products until the scratch disappears.
Scratches can also result from sanding the wood trim next to your windows. It can happen during construction work. These scratches may be difficult to repair. However, a mix of baking soda and water will help smooth out the surface after buffing and eliminate any remaining scratch.
For more extensive scratches you can use a polish for metal to smooth the area and eliminate the marks. Add a small amount the product to a microfibre ball or cotton cloth and gently rub the affected area in an upward motion. Be careful not to apply too much pressure since this can cause further damage to the glass. After the area has been smoothed out using a damp cloth to wash away any polish residue left.
Think about purchasing a non-abrasive glass polish if you've got a an incredibly deep scratch that you cannot get rid of. It is available at any DIY store. Follow the directions on the packaging. You can also use nail polish to cover any scratches on the glass of your window. Ensure that the nail polish is clean and is only applied to the scuffed part of your window.
Haze
The presence of haze within the double-paned windows indicates that the seal between the two panes is broken. It's important to have this repaired as soon as possible so that you don't end up with moisture and dirt build-up between the panes. This can cause damage to the glass and cause an increase in transparency.
There are many options to remove the haze that has formed on double pane windows. Use a defogging solution. But, this is only a temporary solution. If you're looking for a long-lasting solution, you'll need to get in touch with a professional glazing business that can repair the problem and replace the gaskets, if necessary.
A carbide-tipped tool can be used to make tiny holes into the window frame to remove the haze. You can then tuck the desiccate packet inside these holes and then wash the window with ruby alcohol. The water will help remove the haze from the window and wash it.
It is vital to keep your windows well maintained and cleaned regularly to avoid fogging. This will keep the double panes clear and let you take in the stunning view of your garden or home. It is also important to ensure that your home is equipped with adequate ventilation. This will ensure that any condensation is quickly removed, rather than letting it settle and reseal the window.
It is not enough to clean and maintain your windows on a regular basis, but also ensure that they are properly installed. The installation of your windows should be done by an experienced glazing company. This will ensure that the gaskets have been installed correctly and ensu
