When double glazing window seals break, it can lead to mould and damp. This could cause damage to the frame and walls surrounding it, in addition to impacting your health.
Fortunately, the majority of uPVC windows can be repaired with sealing, not replacement. A glazier will usually clean the frame of the window and the glass and then apply a new layer of sealant and smooth it.
Water Leaks
Window seals are made to keep water 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 only annoying but it can cause significant damage to the surrounding structure of your home. It is essential to recognize the issue early and get it fixed by an expert before it gets any worse.
The source of leaking windows is usually not in the glass, but rather on the frame or sill. A leak in this area is the most common indication of a failing window seal. It may be caused by damage to the window seal due to weather or aging, worn-out caulking or even an obstruction in the drainage area resulting in the accumulation of ice or water.
The appearance of water between double-glazed panes is another common sign that the window seal has failed. It's not as risky as a water leak, because the water does not travel far enough to get into your home. It does mean, however, that the inert gases that are trapped between your panes have escaped out. This can reduce the effectiveness of the insulation in your window.
The final common sign of a failed window seal is condensation that forms between the panes. This could be due to a failed window seal, or it could be the result of a damp climate in your home or a problem with the glass. The condensation might not just be irritating but it can also cause the growth of mold and mildew in your home that can be very difficult and expensive to eliminate.
If you're seeing these indicators, it's the time to have an inspection of your double glazed windows. Replacing or repairing your windows will help protect your home from water leaks, reduce energy bills, and reduce draughts. It's a small cost to pay to ensure the safety and comfort of your family.

Condensation
A broken double-glazing seal can let water in the insulating space. This water could cause fogging or misting to the window panes.

If double glazing repairs notice condensation inside your home you should contact a double glazing repair service. Condensation can be an indication that the vacuum seal made by the factory failed and water has gotten into the insulation.
Condensation can be caused by a variety of reasons, but it is usually the result of faulty gaskets, sealants or insulation within the uPVC frame of the windows. There are a variety of options for double glazing seal repair however it is essential that the new seals are properly size to ensure the best seal and a tight fit.
Gaskets are typically made from polyurethane. It is a material that could be used to seal gaps between double-glazed units. They are designed to last a long time but they can perish as time passes because of wear and tear, as well as exposure to various temperatures and weather conditions throughout the year.
Over time, the foam can shrink or crack. This creates a gap in the seal which allows moisture to get into those areas of your double-glazed windows. This can cause condensation, but can also result in the loss of energy efficiency, meaning that you're losing heat from your home to outside air.
One option to fix this issue is to seal the windows. However, this isn't guaranteed to fix the issue because it could only get rid of the condensation that has formed. It does not address the underlying issues that cause the double-glazed windows to leak or develop condensation.
A professional who is able to provide an insurance-backed warranty should replace your windows completely. This means that if the company fails or is shut down, you'll still be covered by the insurance. It's important to know that your replacement windows should be warranted for at minimum 10 years.
Misting
As autumn draws nearer, it's a good idea to check that your double glazing seals are in good working order. Worn-out window seals are not just detrimental to the insulation properties of your windows but could also cause condensation, mold and damp. It is crucial to fix any issues in your double-glazed windows as quickly as you can to avoid further damage and save on energy bills.
Double-glazed windows are made of two glass panes which are joined by a gas-filled interior space. A sealant layer on the outside fills the gap between the uPVC frame and the glass. This is vital to ensure the airtight seal that keeps warm and cool air separate in your home which will save you money on heating bills. The seals may become damaged as time passes due to weather conditions, aging or poor installation. When this happens the encapsulation formula that makes your double-glazed windows so efficient can begin to lose its effectiveness.
If seals that are damaged or broken are not repaired they can cause condensation and dampness which can affect your health as well as the appearance of your window. The dampness and moisture can cause damage to ceilings, walls, floors and other surfaces within your home. They can also cause allergens and irritants that are harmful to your health as well as the health of your family members.
The most frequent issue with double glazing is the misting that occurs between the panes. This happens when moisture is absorbed in the insulated part of your windows. It isn't easy to fix without professional double-glazing repair.
DIY solutions to this issue are available, however, we do not recommend them as they could be messy and can damage your windows. These methods involve drilling holes in the glass units and applying chemicals to eliminate the fog and condensation. This could lead to a variety of problems, such as the possibility of exposing your windows and units to water damage.
Professional glaziers have the expertise, tools and experience to properly seal your uPVC frames and give you lasting results. Not to mention they can also provide guidance on the best methods to maintain your uPVC windows to prevent future problems.
Draughts
A draft coming from your window is a sign that the sealant is likely to have deteriorated. It should be repaired or replaced. This will prevent cold air from entering your home, improve energy efficiency and lower heating bills and increase the comfort level and temperature control.
It is important to keep in mind that not all draughts originate from the window seals but rather from the gap between the frame and the bricks. In certain cases it may be possible to repair this by simply filling the gap with silicone caulk. If this doesn't work, it will need to have the seal professionally resealed.
When the sealant around a double-glazed window starts to break down, it allows for water to enter and can lead to dampness or even mold in certain instances. This can cause harm to health, and cause damage to the property. If you notice any problems with water ingress and you want to take action as soon as you can. If your windows are still covered by a warranty, it's worth checking to determine if the company who sold them will pay for the cost.
The windows themselves are usually covered by a warranty that could last for 10 years or more, but some companies offer lifetime warranties, so it is worth looking into this information. If your double glazing falls under warranty, it is recommended to contact the company that sold them as soon as you can and let them know about any issues you're experiencing. It is recommended to contact the company in person or via email and letter. This will ensure that everything is documented and clear.
It is also worth noting that draughts can be often caused by faulty hinges, not the lack of seals that are effective. The hinges cover the window sash which is the part you open. If they are not oiling them regularly and become stiff, they may develop. This could cause a gap to form between the sash frame and the sash, allowing cold air to enter the home. Replacing the hinges will fix this issue without affecting window seals.
