What's Holding Back The Double Glazed Repair Industry?
How to Deal With Double Glazed Repair

You should ensure that your double-glazed window frames are inspected regularly, particularly when they are shrinking or expanding. This will reduce the chance of drafts.

If you notice condensation appearing between the glass panes, the seal may be failing and needs to be replaced. Replacing the seal will not only help to reduce condensation, but also help to reduce the cost of energy.

Cracked or Broken Panes

Double glazing is not impervious to damage and faults can occur which can affect the energy efficiency of windows and doors. Repairing double glazing is a simple process but the right tools and knowledge are required to carry out top-quality repairs. It is recommended to work with a professional firm to complete the task rather than trying it yourself.

A broken or cracked pane is the most frequent issue for double-glazed windows. A blow or knock from outside can cause this, as can attempts to open a window that is closed. The glass may break or crack into smaller pieces, based on the size of the crack and the force that is applied to it.

If windows with double glazing are susceptible to cracking it can be repaired with a form of putty or tape. This will stop the crack from extending or getting worse, and will prevent wind, water or other elements from entering your home through the cracks.

Condensation in double glazing is another frequent issue and is often the result of a breakdown of the window seal. It is a normal occurrence that happens due to weather and temperature changes. Before you attempt to repair your windows, check to see if they are still covered by warranty.


Typically, this is covered by the company that you purchased the double glazing from. Therefore, it is important to contact them immediately and explain the issue clearly. It is best to address this in writing rather than via text message or phone and keep an original copy of the correspondence.

Drilling a hole in the centre of a misted pane is a popular method to fix it yourself. A desiccant that is specially designed is inserted to absorb moisture and this can help the condensation issue to heal itself. However, this is only a temporary solution and it is recommended to get your double-glazed windows replaced by new windows as soon as you can.

Misty Panes

When double-glazed windows start misting up it can be a major trouble and can cause major disruption to your home. Once you identify the cause, it's relatively simple to fix. Most of the time, the problem is due to a problem in the seals that protect your window panes. This allows moisture be able to get. This could be caused by inadequate installation, drainage issues or even seals that are defective from the window manufacturer.

Standard sealed units consist two glass panes, sandwiched by a hollow spacer (shown above). The surface of the spacer bar is perforated and the spacer bars have been filled with desiccant to suck up any moisture. The two glass panes then are sealed together and the whole unit is filled with gas to improve its thermal efficiency.

As you can imagine, if the sealed unit fails, moisture could get in between the panes and cause condensation and mist. This can also cause heat to escape from your home, which could result in a significant amount of money being lost due to energy bills.

However, fixing double glazing windows that have been misted isn't easy and shouldn't be attempted by those who don't have an extensive understanding of glazing and the construction industry. However, if you are willing to take on the challenge then it is possible to fix a misted sealed unit by adding moisture absorbing desiccant back into the gap between the glass panes.

Be aware that this is a temporary fix, and the condensation might occur again. The process will need to be repeated. It is much more efficient to replace the misty unit. It's also more efficient and cleaner. A replacement will also restore the original insulation of your house which isn't possible through a repair. We suggest getting in touch with a reputable double-glazing company if you're having trouble with condensation and misted windows. In the meantime, you can try making sure your windows are as dry as possible by ensuring they're properly ventilated and cleaning them regularly.

Water Leaks

No matter if they are brand new or old, double glazed windows should not leak. Leaking windows aren't only an inconvenience, but they can cause serious damage to your home. This includes the growth of mold and structural damage as well as higher heating and cooling costs. Contact a professional window company as soon you suspect a problem.

Window leaks are usually indications of a problem with the seals that connect the panes of glass. If you notice condensation between the glass panes, it is an indication that the seal between the two panes has become weaker. The moisture is now leaking through the insulating space that is between the two panes. Although a small amount of condensation is normal, if it continues to grow and is visible on the interior or exterior of your home it is time to call a repair service in.

Water accumulating at the bottom of your window frame is another typical cause of leaks. This could be a sign of clogged drainage holes, improper flashing or a sloped sill. It is simple to clear a clogged drain hole by using a coat hanger. Using roofing caulk, you can easily fix flashing that isn't working properly. If the window sill is sloping to one side it may be due to an incorrect pitch. A reputable window repair company can identify the cause and provide an immediate, cost-effective solution.

It is not uncommon for UPVC windows that are older to leak or break. However, it is more cost-effective and efficient to use a double glazing repair service. They can restore your windows' appearance and function to how they were when they first came out. They can also replace handles, hinges and locks if required. A reputable window repair service will also provide you with a kind of guarantee for their work, which you could not receive if you tried to repair the window yourself.

The difficulty of opening

If you notice your windows are becoming harder to open, contact the company from which you purchased windows. In the majority of cases, the problem can be resolved with an easy fix. If the issue persists and you are unable to resolve it, you should consider replacing your windows with new contemporary designs. New double glazed Windows offer the most modern features to ensure your home is secure and warm. They include slimline uPVC frames or aluminium frames with high-tech insulation that blocks heat from escape and cutting-edge security equipment.

Condensation between the glass panes is a common sign that double glazing requires repair. This is due to an issue with the seals between the two panes. Inert gasses are supposed to escape between the panes of glass and be replaced by humid air. This will keep your windows airtight and energy efficient. If this doesn't happen, then the seals could have been damaged over time due weather conditions or other factors.

A draught emanating from your double-glazed window another sign that the seals have failed, meaning that cold air is leaked into your home. This can lead to higher energy costs since your heating system will have to work harder to maintain the temperature in your home.

In some cases the draught could be fixed by lubricating hinges or handles on your double-glazed doors or windows. It is crucial to remember that this is a temporary fix and if the issue persists, then you'll have to seek out the experts.

To help reduce condensation, you can install ventilation in your windows and doors for reducing condensation, such as extractors or air bricks. It is also recommended to allow your double-glazed doors and windows to breathe, which can be achieved by using trickle vents.
