It can be caused by many causes however the most common are excessive humidity or poor ventilation within your home. The humidity can easily form droplets of water on surfaces that are cold, which is why your double glazed windows are more likely to display condensation than single-pane windows of earlier. Install a vent in your bathroom or kitchen if it is especially humid.

They could be able to replace the unit, or they may need to install one-way air vents to stop any further condensation. This is a better option than replacing your double-glazed windows as you will save time and money.
Foggy Glass
The windows that are stained with fog indicate that the seal on double-paned windows has failed. Double-pane windows have two glass panes with a gap in between. This space is filled with energy efficient gasses such as argon or Krypton. This helps keep temperature-controlled air inside your home, while keeping the outside elements out. However, if the seal fails, moisture could get in and cause fog. Foggy windows can make your home less efficient and unattractive.
Many homeowners prefer hiring an expert for window repair instead of replacing their windows. Before making recommendations, a glass specialist can determine if the windows can be repaired.

Windows that have become cloudy can be fixed by defogging. It's a process that involves drilling holes in the window, infusing cleaning solution to remove the soiled liquid, and drying the interior of the glass. This is a relatively new technique and is worth a second look to determine whether it's right for your home prior to committing to it. It will not, however bring back the energy efficiency that's been lost due to the deterioration of seals.
Cracked Panes
A crack in a glass window that is double-glazed might seem like something minor but it could cause significant damage. It's important to have the crack repaired as quickly as possible in order to avoid further damage, particularly if it's on inside of the glass.
Double-pane windows consist of two glass panes that are connected with a space between which is filled with an inert gas, like argon or krypton. This is to ensure that heat from your home doesn't get transferred through the glass. The gas slows the heat transfer, so the warm air from your home may travel through the window at a slower pace than if there were nothing between the panes of glass.
It is essential that windows are installed correctly and with a good seal. The windows must be installed by a licensed glazier who will be able to fit the panes of glass with a secure seal to ensure that they are properly insulated to the best extent. If the seal on the window has failed, the gas inside the panes could leak out and diminish their insulation capabilities, leading to cracking between two panes.
Poor installation can also cause double-paned windows crack. The glass will expand and contract at different rates. This could cause stress cracks to appear over time, weakening the glass. If this happens, you should find a glazier that can replace the damaged glass with one that is better suited to your home.
If you find a small crack in your double-glazed windows it is crucial to understand that the crack cannot be repaired by simply filling it in with adhesive. This is because double-pane windows rely on an air-tight seal between the two glass panes, and any cracks can worsen in time, leading eventually to complete breakage.

It is crucial to keep in mind that broken glass can be dangerous. Therefore, it is recommended to contact a professional with the right equipment to do the job. They'll also know how to remove the old sealant, without causing damage to the glass.
Leaking Seals
The IGU is made up of two or three parallel sheets annealed glass or tempered. The IGU is fixed by a combination of aluminum spacers, polyurethane. This creates an airtight seal, which prevents moisture from entering your home. In time the seal could break down and allow water to get in.
Typically, this is caused by the natural expansion and contraction of the materials used to create your window. The sealant, either silicone or polyurethane, can expand and contract slightly in response to changes in humidity and temperature, putting the IGU at the risk of deteriorating. When the seal is damaged the insulative fill gas can escape and leave your windows with a hazy appearance and draughts that reduce the efficiency of your house.
If the window seal fails, it may also cause condensation or water to form between the panes, which you cannot wipe away. In some cases, moisture may leave a permanent stain left on the glass of your window.

This process requires professional equipment that removes moisture, fills in the void with the gas argon or krypton and then seals the window without letting gas escape. repairing double glazing of this service can vary depending on the type of IGU you have and the location, but most double glazed windows can be repaired within one hour or two.

Choose energy-efficient coatings and glazing that reflect instead of absorbing the sun's rayons. This will make your home cooler and more comfortable, and it's an affordable way to improve the appearance of your windows. Use caulk around the frame of the window to seal any gaps that let cold air in and warm air out. This can be a more cost-effective option than replacing the entire window.
