How to Repair Double Glazed Windows
Double glazing is typically covered by a warranty for 10 or 20 years. If your double glazed windows are showing signs of aging, you may be eligible to have them fixed under warranty.
Double
glazed window repair involves re-sealing your existing glass unit. The seal is not working in the event that you see misting.
Glass that is damaged
A seal that is airtight is vital for double pane windows to function effectively. The most typical 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 corrected however, it's a sign that your glazing unit needs replacing. If you have an older double glazed
window doctor, this may require replacing both the frame and the glass. If the frame is in good shape however, you could typically save money by replacing just the glass.
Glass is brittle and it's not uncommon for double-pane windows that develop cracks as time passes. If the cracks aren't caused by mechanical damage or an unusual impact on the window they can be fixed with epoxy and elbow grease. Begin by cleaning over the cracked area with a wet cotton rag. Then, apply epoxy to the crack, according to the instructions of the manufacturer. Let the epoxy completely dry before sanding and painting the repaired area.
A simple strip of masking tape can be used to keep cracks from spreading. One strip of tape placed on both sides of the damaged area is enough to keep superficial cracks, such as stress cracks that are caused by low temperatures, from worsening. If you have deeper cracks in your glass that are already present, it is recommended to speak with a professional for the repair.
It's risky and difficult to replace a single pane of double-paned windows. Double-pane windows are constructed as a whole unit and sealed in the factory with inert gas, so it's impossible to remove the glass without causing damage to the entire 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 replace any broken glass. This will protect you from any glass shards that could fall in the process. It also helps prevent any damage to the molding or trim of your home.
Condensation Build-Up
It's important to understand that condensation in the windows can be normal. This is due to the difference in temperatures and humidity of the air. The water vapour that is present in air condenses when it comes into contact with cold, inaccessible surfaces like windows. This is usually a good thing during winter because it helps prevent loss of heat.
However, if you're finding that your windows are appearing cloudy with a film of water on them, it's the time to contact an expert glazier. This is a sign that the seal between the two panes is beginning to weaken and allows moisture to enter the
window doctor.
You can stop this from happening by making use of dehumidifiers, increasing ventilation,
glazed or applying de-icing agents. There are also professional companies that can help repair condensation build-up in double glazed windows by drilling holes in the window and injecting or pumping special 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, cleaning them thoroughly and then refilling with desiccant before sealing them back up. This will usually be an expensive option, but it is worth checking whether the company you use is fully insured and registered with FENSA.
It is crucial to remember that tampering with your double glazed windows is not advised and could invalidate any guarantees. If you have windows that have a warranty It is recommended to notify the manufacturer of any problems as they'll be accountable for the replacement of any defective units under warranty. It's best to consult an expert before undertaking any DIY repairs. This is particularly applicable to older units, because they're more prone than newer ones to fail. If this happens, it's recommended to replace the entire glazed panel. The result will be brand new windows that will last for many years.
Scratches

Add a small amount of the product to a microfibre ball or cotton cloth and gently rub over the affected area in a circular motion. Avoid applying excessive pressure, because this could cause further damage to the window. Once the area is smoothed, use a damp cloth to wash away any excess polish residue.
