Water Leaks
Window seals are designed to keep moisture to stay out of your home. However, when they start to break down, it could result in water leaks around your windows. A window that is leaking is not just a nuisance, but it could cause serious damage to the structure of your home. It is essential to recognize a problem early and have it repaired by a professional before it gets any worse.
The cause of windows that leak can be found in the glass itself but on the frame or sill. This is the most common sign of a leaky seal. This can be due to damage to the seal caused by weather or age or worn caulking or even a blocked drain which can lead to the accumulation of ice or water.
The appearance of water between double-glazed panes is a common indication that your window seal is failing. While this isn't quite as hazardous as a leak since the water doesn't travel enough to get into your home. However, it does mean that the inert gas that is sandwiched between the panes has been released, which can reduce the insulating value of your windows.
Condensation in between the panes is another common sign of a leaky seal. It could be the result of the window seal failing, or it could be due to a damp climate in your home or a problem with the glass. It's not just annoying but it can also lead to mould and mildew growth in your home. This can be difficult and expensive.

Condensation
A broken seal for double glazing could allow water to enter the gap between the insulating elements. The water could cause condensation inside the window panes, and could also result in fogging or misting.
If you are noticing condensation inside your home It's time to call a double glazing repair company. Condensation is an indication that the vacuum seal fabricated by the factory has failed and water is leaking into the gap between the insulated and non-insulated.
Condensation can be caused by a variety of factors but it is most commonly a result of defective gaskets, sealants or insulation within the uPVC frame of the windows. There are many options for double glazing seal repairs however it is essential that the new seals are properly sized in order to ensure a perfect seal and a snug fit.
Typically, the gaskets that are used to seal the gaps between your double-glazed units are made from polyurethane foam. These are designed to last for a long time but they can perish as time passes because of wear and tear and exposure to various temperatures and weather conditions throughout the year.
Over time, the foam can shrink or crack and this creates a gap in the seal that allows moisture to enter the double-glazed windows. This can lead to condensation and a decrease in energy efficiency.
Re-sealing windows is one option to address this issue. This isn't a 100% fix as it will only remove the existing condensation, and not address the issues that cause the double-glazed windows to leak or develop condensate.
Another solution is to have your windows replaced completely. This should be handled by a professional who provides an insurance backed guarantee. This means that if the company fails or goes under, you'll remain protected by the insurance. It's important to note that the warranty for windows replacements should be a minimum of 10 years.
Misting

Window seals that are damaged can affect the insulation properties of your windows and can also lead to condensation, mold and dampness. It is essential to address any issues with your double-glazed windows as soon as possible to avoid further damage and save money on energy costs.
Double-glazed windows are constructed of two panes glass that are held together by a gas-filled interior space. The sealant layer on the outside fills the gap between uPVC frames and the glass. This is essential to maintain the air-tight sealing that keeps warm and cool air from your home which will save you money on heating bills. Unfortunately, over double glazing repairs will be damaged due to aging or weather conditions, or even inadequate installation.

Draughts
A draft coming from your window indicates that the sealant is likely to have deteriorated. It is recommended to repair it or replaced. This will stop cold air getting into your home, improve the efficiency of your energy and reduce heating costs, and also improve the comfort level and temperature control.
It is important to keep in mind that not all draughts originate from window seals but from the gap between the frame and bricks. In some instances, it can be possible to repair this by simply filling the gap with silicone caulk. However, if this is not working, it will require resealing professionally.

When the sealant around a double-glazed window starts to break down it allows water to enter and can lead to damp or even mold in certain instances. This could affect health and can cause damage to the property. It is important to address any water ingress issues when you spot them. And if your windows are still in warranty, it is worth contacting the company you purchased windows from, since they could pay for the repairs.
It is worth checking if the windows are covered by warranties. Some companies offer lifetime warranties and others offer 10 years. If your double-glazed windows fall under warranty, you should contact the company that sold them as soon as you can and inform them about any issues you're experiencing. Ideally, it is best to make this contact in person or by email and letter, so everything is recorded and clear.
It is also worth noting that draughts are usually caused by defective hinges and not by an ineffective seal. The hinges are responsible for closing the window sash (the section that you open) but can become stiff as time passes if they're not regularly oiled. This can cause a gap to form between the sash frame and the sash, which lets cold air into the house. This issue can be resolved by replacing the hinges, without damaging window seals.
