Read on for more information about your double-glazed windows and if they can be repaired.


Double-Glazed Windows

Double glazing is a window type that involves a gap of air between glass panes. It insulates against the transfer of heat between varying outside temperatures. Double-glazed windows can help to lock in heat and are also referred to as insulated glass units or IGUs.

The Most Common Faults of Double-Glazed Windows

Some of the most common faults of double-glazed window units include:

  • Becoming difficult to open and close
  • Sagging or dropping over time, causing the units to not fit properly
  • Locks not working
  • Window seals deteriorating
  • Condensation or steaming up of the glass
  • Cracking or shattering

These have been reported to be among the most common problems that can occur with double-glazed windows (and doors). If you have read this list and are now feeling worried that your double-glazed windows are going to fail you, then you shouldn’t be too worried yet. Most people do not have issues with their double-glazed glass, and double-glazed windows are in fact a very reliable window choice.


Double Glazing Repair

Double-glazed windows often come with a warranty of 10 to up to even 20 years! It is handy to check what cover yours has when you come to spot a fault. Contact the glazing company you purchased your windows from if you are eligible to have your windows fixed if you are under warranty.


Fixing Condensation in Double-Glazed Windows

A common problem is condensation on the inside of windows or in between the glass panes. This means that your double-glazing has become faulty.

Condensation means that windows are not doing their job correctly and the seal is no longer air-tight holding in the insulating gas between the panes. This failure then results in condensation.

Fixing a condensation problem can be achieved. A method that can be used involves drilling a small hole into the glass pane unit. A desiccant, which is a substance used to sustain dryness, is used to absorb any moisture.

A special drying agent is injected or pumped into the hole to dry out the window with an agent that has anti-fogging abilities to help prevent the problem from recurring in the future. Although do note, this method has no guarantee.


Consider Replacing Window Seals

The window gasket, otherwise known as window seal is something that will be attached to your double glazing, this is what is responsible for sealing air in between the two panes of glass in your double glazing units and keeping drafts and moisture out of your home.

Window gaskets can perish and shrink over time - this is a naturally occurring process. This is down to the sealant expanding and contracting through different temperatures and weather conditions throughout the year. This causes it to potentially crack and shrink over time pulling it away from the window frame.

If your window gaskets have shrunk or cracked, it may be time for them to be replaced. If it is just the sealant that is the fault, this can be fixed without having to pay for brand-new double glazing along with the installation costs. This option is a much friendlier option for the environment and to your wallet as well.

Replacing gasket seals will also help your home to be more energy efficient too. Save money on not replacing your entire window units and also on your energy bills.


When Should I Replace a Double-Glazed Window

If you have assessed your double glazing and you are thinking that your windows are faulty beyond repair, then it may be time to replace them. Double glazing can be outdated and could be costing you money if they are seriously damaged.

It is sometimes best to bite the bullet and reinvest the money into purchasing some new double-glazed window units for your home. On a positive note, this could save you more money in the long run, especially during the winter months when you will want your double-glazed windows to keep in as much heat as possible.

Some window types may be more prone to issues and may be easier and cheap to replace rather than repair in some cases.
