How to Tell If Your Double Glazed Windows Need Repair Double glazed windows are a fantastic investment for your home. However, as time passes, they may begin to show signs of wear and wear and tear. Sagging and difficulty opening double glazing could be due to a poor seal which can result in condensation and draughts. Installing trickle vents allows fresh air to circulate through the room. Cracked glass A double-glazed window with cracks shows that the seal between the two glass panes is broken. This signifies that the window is no longer able to keep out heat or cold and, in extreme cases the entire unit could need replacing. Thankfully, damaged windows can be fixed with a few simple steps. If you decide to tackle the project yourself, you must always consider your safety by laying down a cloth or tarp to keep any shards of glass that drop and put on appropriate eye protection and glass handling gloves. It is essential to wash the tools prior to making use of them, as cleaning broken glass can be risky. If you don't do it correctly, it could lead to cuts. It's important to analyse the extent of the crack and its origin. If the crack was caused by a recent impact or another external factor, it's best to consult an expert to determine if a new window is better suited to your home. Once you've figured out the root cause of the damage and have identified the cause, it's time to begin the process of repair. To begin, clean over and around the glass pane that has cracked using a soapy water mix. Dip a cotton rag into the mixture and gently rub the crack to get rid of any dirt or debris. One of the most effective methods to stop cracks from becoming more severe is to put a strip of masking tape over it. This will stop superficial cracks like stress cracks from getting more serious by allowing the glass to expand and shrink without exerting too much pressure on it. If the crack is deeper you will need to use stronger tape that is able to withstand greater tension and extends a few inches over the crack on both sides. Another option is to use epoxy to cover the crack. However this is a much more labor-intensive option, and is best used for more serious cracks. You'll also need to take care to clean the area and around the crack and wipe away any excess epoxy from the frame. Condensation Condensation can build up in double-glazed windows for many different reasons. If you notice condensation on the inside of the glass, it means that there is a lot of moisture and not enough air circulation within the space.

For example, plastering and painting both release huge amounts of water. If there is condensation between the two panes of glass it could also be a sign of a fault with your window. Most commonly, this is caused by a breakdown in the desiccant that is located between the two glass panels. The material is extremely absorbent and can soak up any moisture that is present in the gap. If you find even the tiniest flaw or crack in this area, the desiccant quickly becomes saturated and moisture appears as condensation.
