Damaged Seals

If a window seal fails, moisture can get inside the glass panes, causing condensation or fogging. This will impact how well the windows insulate, and can result in more expensive energy bills since you will need to utilize more cooling or heating.

double glazing Maidstone glazing was developed was to save homeowners money on energy costs by better insulating their homes. Insulated glass is composed of two glass panes bonded together with spacers and then filled with inert gases such as xenon, argon, or krypton to reduce heat transfer. When a window seal fails the entire insulating gas is released, which makes the windows less effective at saving energy.
A damaged window seal could cause many issues, including a decrease in energy efficiency, water leaks, and decreased security. To avoid problems like these it is essential to replace the seals when they become damaged.

Condensation on the Panes
If you see mist or condensation between your double glazing panes, this is an indication that the seal has failed. The gas that insulates the sealed unit has evaporated. This is a serious issue, and your windows won't longer perform as well as they did in terms of thermal performance.
It is possible to get condensation inside your double-glazed windows when drying your clothes in a space that is not ventilated or has damp conditions. This kind of condensation typically occurs at night, when the glass is cooler. It will disappear in the morning when the sun comes up. It is a common event and is not a sign of a problem with the glass or your windows itself.
The condensation or mist that forms on the outside of your double glazed windows could be due to the lack of ventilation in the room, humid conditions, or by using specific cleaning products that contain harsh chemicals. These products can damage the seals which keep moisture from the insulation gap between the panes.

Leakage
You should fix your windows as soon as they're misting. It's not only unsightly but also a sign that your windows aren't sealed and properly insulated. This is a huge issue for homeowners, as it means they are losing energy efficiency and paying more to heat their home.
The misting that occurs in your double-glazed windows is caused by the temperature difference between the glass panes and air outside. This causes moisture to accumulate inside the window, leading to a gap between the panes. This is commonly known as a "blown" window.
Replacing the blown window by a new one will increase your home's energy efficiency and help to save money on heating bills. A new window will close the gap effectively, preventing cold air from getting into your home and warm air from escaping it, ensuring that your heating stays in your home exactly where it should be.
The frames of double-glazed windows can also become difficult to open or close. This is usually caused by extreme weather conditions like high temperatures. The frames can be cleaned using cold water to address the problem. This reduces the size of the frame, making it easier to open and close the window or door again.
You can also do it yourself. Sand and scrape the rabbets that will fit inside the frame of the window until they're bare wood. Paint them with an external primer. Then, you can use putty to fill the gaps where rabbets were, being careful not to create a smooth surface - you want the putty to stick and be as solid as you can.
Contact the installers of your double-glazed window door to get guidance on how to fix the issue. If your windows are covered by warranty, they might be able to replace windows at no cost to you. If not, you can contact a reliable repair company for double glazing like Mr Misty Ipswich to see what can be done.
