What Does Condensation On Double Glazing Mean

If you’ve taken the decision to invest in double glazing, you may be basking in the warmth and counting the pennies you’ve saved on your energy bills, but what happens if you spot condensation patches? Double glazing represents a brilliant investment, but it’s not immune to damage. If you notice condensation clouding your windows, it’s wise to seek urgent advice.

What does condensation on double glazing mean?

Double glazing is robust and energy-efficient because it is formed using two panes of glass, rather than one. Between the panes, there is a small gap, which is usually filled with argon. This harmless gas helps to create a protective barrier, which regulates temperature throughout the year, meaning that you feel comfortable come rain or shine. Problems become apparent when the window seal is broken, and the gas is able to seep out. If you can see condensation on your windows, and they are double glazed, this almost certainly means that there are issues with the seal. When the seal is damaged or worn, this creates moisture between the two panels of glass and reduces the ability of the window to protect your home against the elements.

What to do if you spot condensation on your windows

If you have double glazing, and you notice condensation patches, it’s wise to get in touch with the company that supplied and installed your windows as quickly as possible. Once a seal is damaged, it cannot repair itself, and there is a risk of further deterioration and the development of mold and mildew, which thrive in moist environments. Once a window seal is broken, it is not possible to repair it, and the window must be replaced. It’s better to do this as a priority to prevent damage to the structure of your home and to keep mold at bay. If mold does develop, or the window frames start to rot due to damp, this can affect the aesthetic of your home, as well as its value.

When you buy new windows or doors, they come with a guarantee. If you have problems with your double glazing, check the details of your warranty to see if you are eligible for free replacement windows. If your windows are still covered by a warranty, call the company responsible for installation immediately.

It’s particularly beneficial to act quickly if you see spots of condensation developing on your windows if you plan to sell your home. Double glazing can be an incredibly appealing feature for buyers, but only if it’s in good condition. If the windows are misty and there are spots of mold developing, this is likely to put potential buyers off.

Double glazing offers an array of benefits for homeowners, including increased warmth in the winter and coolness in the summer and lower energy bills. If you have double glazing, it pays to keep an eye out for problems, which could affect the aesthetic and resale value of your home and the performance of your windows. Condensation is a sign that the protective seal has been worn, damaged or broken. It’s always a good idea to act quickly to prevent further damage and ensure you’re able to enjoy the benefits of new windows as soon as possible.
