Damaged Glass

A seal that is airtight is essential for double pane windows to function correctly. The most frequent indication that a seal is failing is the formation of condensation between the glass plates. While condensation between glass isn't a serious problem and can be fixed, it's typically an indication that the glass unit is in need of 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.

One strip of masking tape applied to each side of the crack ought to suffice to stop cracks that are superficial from spreading, such as stress-cracks caused by low temperatures. However, if you're dealing more serious cracks that have already formed in your glass, it could be best to call an expert to ensure the safety of the repair.

There are companies that can remove excess moisture from double-glazed windows through drilling into the frame and injecting desiccant. This requires removing the sealed unit from the frame and then cleaning every glass pane before refilling the desiccant. This is typically a more expensive option but it's important to ensure that the company you use is fully insured and is registered with FENSA.

Scratches may also occur when finishing sanding wood trim close to your windows. They may also occur during construction. They can be difficult to repair, but a small amount of baking soda and water can help smooth the surface and eliminate any remaining scratches.

Metal polish can be used to remove more severe scratches. Add a small amount of the product to a cotton ball or clean microfibre cloth and gently rub the affected area in an upward motion. Be cautious not to apply too much pressure, as this could cause damage to the glass. After the area has been smoothed out, use a wet cloth to remove any polish residue left.
