Can Sealed Units Be Repaired?

If your double glazed sealed unit has misting or condensation in the panes of glass, you might be wondering if they can be repaired. In some cases, it is possible. However, replacement is often the better long-term solution because it restores full insulation and energy efficiency.

Should You Repair or Replace?

Double glazing repairs can sometimes help, but they may not fully restore insulation. On the other hand, replacement provides better energy efficiency, durability, and overall performance. Ultimately, the best choice depends on the severity of the damage and the long-term benefits you want to achieve.

Common Problems 

First, condensation or misting appears between the glass panes of double glazed windows, which causes the insulation to become less effective. As a result, this leads to higher heating costs. Over time, the glass may also become cloudy or foggy, affecting both visibility and the overall appearance of the window.

How Are Double glazed Units Repaired?

In many cases, professionals can remove moisture and apply an anti-fog treatment to restore a double glazed sealed unit. Additionally, some methods use desiccants like silica gel to absorb the moisture. However, if the seal is badly damaged, replacement is often the best option to ensure long-term effectiveness.

DIY vs. Professional 

While minor issues may be fixed with DIY methods, these solutions are often temporary. Professional repair or replacement, on the other hand, restores full performance and ensures lasting results. Experts use specialised tools and techniques to provide a durable fix that DIY methods cannot match.

Cost & Warranty

Generally, window frame repairs are more affordable than replacing the entire window. Furthermore, many professional repairs come with a warranty, offering you peace of mind and ensuring the work is completed to a high standard.
