Broken or cracked Panes

Double glazing is not impervious to damage and there are a few issues that can affect the efficiency of energy-efficient windows and doors. Repairing double-glazing can be an simple task, but you will need the right tools and knowledge to do it right. It is recommended to use a professional firm to perform the work rather than attempting it yourself.

The most common issue that affects a double-glazed window is a broken or cracked pane. A blow or knock from outside can cause this, as can attempts to open a stuck-closed window. Glass can break or crack into pieces depending on its size and the force that is used to crack it.

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

Condensation in double glazing is another common problem and this is often caused by a failure of the window seal. It is a normal occurrence that occurs due to temperature and weather changes. Before attempting to repair your windows, make sure to see if they are still covered by warranty.

Typically, this will be covered by the company you purchased your double glazing from so it is crucial to contact them immediately and explain the issue clearly. It is best to do this in writing, rather than by text or phone, and always keep an original copy of the correspondence.

If you want to try and fix a damaged or misted window yourself, a typical procedure is to drill a hole into the centre of the affected window. A desiccant that is specially designed is put in to absorb moisture which can aid in helping the condensation problem to resolve itself. However, this is only a temporary solution and it is recommended to have your double-glazed windows replaced with new windows as soon as possible.

Misted Panes

If double-glazed windows begin misting up it can be a major pain and can cause significant disruptions to your home. Fortunately, it can be fairly simple to fix the issue once you understand what's causing it. Most often, the cause of the issue is a failure of the seals between the window panes that allow moisture to enter. Poor installation or drainage issues, or even defective seals from the window manufacturer can trigger this issue.


Standard sealed units consist two glass panes that are sandwiched by an open spacer (shown above). The inside of the spacer bar has been perforated and the spacer bars are filled with desiccant to suck up any moisture. The two glass panes are sealed and the whole unit is injected with gas to increase its thermal efficiency.

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

Unfortunately, repairing the misted double glazing window can be a little tricky and shouldn't be attempted by anyone without an extensive understanding of the construction industry. However, if you are prepared to take on the challenge then it is possible to fix a sealed unit that has been misted by putting moisture-absorbing desiccant to the gap between the glass panes.

Be aware that this is only a temporary fix, and the condensation might occur again. The process will need to be repeated. It's more efficient to replace a misted glass unit and will be more efficient and cleaner. A replacement can also restore the original insulation of your house that isn't accessible in repairs.

Water Leaks

A small amount of condensation is normal. However when the issue persists and appears on your home's interior or exterior then it's time to call a repair service.

Another common cause of leaks is the accumulation of water on the bottom frame of your window. This could be a sign of drainage holes that are blocked, improper flashing or an unbalanced sill. A drainage hole that is clogged can be easily fixed by using a coat hanger wire to clean out the gunk. Incorrect flashing is also easy to fix using roofing caulk to fill in the gaps around the frame. A misplaced pitch could be the cause of an inclined window sill to one side. A professional window repair service will be able to determine the source of the problem and provide an affordable, fast solution.

Condensation between the glass panes is another common indication that double glazing requires repair. This is caused by an issue with the seals between the two panes. Inert gases are designed to escape between the two panes of glass and then be replaced by moist air. This will keep your windows airtight and energy efficient. If this isn't happening, the seals could have degraded or simply broken down, which is something that can occur in the course of time because of weather changes or other causes.
