Prevent Window Condensation with These Pro-Tips: How to Successfully Defog Your Windows

If you are considering having your windows defogged, there are a few things to consider first. Defogging your windows is a shorter-term, cost-efficient solution to replacing the whole window. It is possible to have a professional company defog the glass, which should prolong the life of the window compared to leaving moisture between the panes of glass to cause permanent damage. However, the process isn’t cheap; estimates state the cost is between a half and a third of the full replacement cost.

When you hire a professional company, it’s important to find out what the length of warranty is for the work and if they will stand by the valuation if there are streaks that appear in the weeks after the window valve has been installed. It’s very common for the window to fog up again during that time as the spacer bar dries out.

If your window has had a build-up of moisture for a prolonged time, it’s possible the glass has been permanently damaged and that the defogging process may not be able to restore it. Consequently, when getting your quote it’s important to be honest about how long the problem has been around, to avoid wasting money on a pane that needs replacing.

Tempered glass is an especially problematic window type. The defogging process doesn’t replace the argon and krypton gases used in new windows to increase the insulating properties, and it can’t be used on windows with tempered glass. Such windows are usually found in conservatories and solariums, or when a window sill is at a low level. Generally, there’s a white mark in the corner of the glass marking them as tempered.

Windows you consider having defogged need to be evaluated to determine the cost-effectiveness of the defogging process in comparison to just replacing the glass. Although defogging prolongs the life of your window, at some point it won’t be worth it and replacements will be the cheaper solution. Check alternative solutions such as just replacing the glazing before committing to the defogging process. Whilst it isn’t a miracle solution, defogging is still a great way to prolong the life of your windows and can be relatively low cost compared to replacing your windows.
