Double Glazing Unit Repair
If you have double glazing that appears misty or cloudy and can't be wiped clean it's probably "blown". This occurs when the gap between the window panes is widened due to the degrading of the window seals.
Replacing the gasket seals on your windows can fix this issue and is less expensive than replacing the whole double-glazed unit.
Seals
The window seal, often referred to as the window gasket is responsible for sealing air in between the two panes of glass in your double glazing. This will prevent cold drafts from entering your home and also prevent moisture and condensation building up between the glass panes.
Over time, this seal will perish due to rapid temperature changes throughout the year, causing it to shrink and eventually pull away from the frame. Replacing the window seal is a cheap and effective way to fix your double glazing units.
A typical sign that your window seals have broken down is condensation that forms between the two glass panes in a double glazed window. This is due to the accumulation of humidity in the home. The excess moisture cannot escape through the glass, and it cools down and forms on the windows' surface pane. This can cause the windows to become cloudy and obscure your view from the window.
In addition, if a window is misting, the condensation can also build up on the exterior of your window frames. This can damage the timber frames since it can cause rot and cause a damp home. Repairing a window leaky early can save you lots of money, avoid damage to your home and help to keep your health safe as exposure to excess moisture can trigger respiratory issues asthma, allergies, and bronchitis.

This will ensure that the surface of the glass is clean and free of dirt and grime before applying the new sealant. After cleaning the glass, you should seal it with the solvent-based sealant.
Before starting, ensure that your workspace is ventilated. Once the workspace is clear, carefully cut through the black sealant on the perimeter of your sealed unit to separate the silver spacer bar from the glass panes. Once the two are separated then use a knife to remove as much sealant as possible. Then scrape any remaining residue off using the help of a scraper.
Glass
Double-glazed windows consist of two layers of insulated glass that are separated by a spacer that creates an opening. The edges are then sealed. This makes the windows airtight and also prevents moisture from getting into your home. The glass is available in a variety of patterns, thicknesses and tints as well as Low E and acoustic options.
If your double glazing is experiencing issues like fogging or condensation, this is due to an issue with the seals. As time goes by these become weak and tiny holes begin to develop in the sealing around the edge of the glass unit. When these begin to appear, the moisture can penetrate into your home, which can cause damage to your home such as damp, rot, and mould.

When you split the glass, be sure to not cut the backing of the unit or the spacer bars. It is also recommended to use an additional pair of hands to keep the unit when you're working.
After carefully splitting the glass, you'll have to take the beads off. You can scrape off any sealant residue that is left. This will have to be replaced with the highest quality glazing sealing compound. The sealant you choose to use will need to be water proof, thermally resistant and join the two panes of glass unit together.
