Double Glazed Windows Repairs
If your double-glazed windows are hard to open or have a haze between the panes, this could be an indication of seals that are not working properly. It is worthwhile to get them fixed If this is the case.
This can be accomplished without replacing the windows, and will be much less expensive in the long term. This type repair requires specialized tools which is why it's advisable to leave it to an expert.
Seals that are damaged
The window seals can be worn down over time and allow argon gas or Krypton to escape through the panes of double- or triple-paned windows. A damaged seal allows air from outside to enter and the argon gas that is used to insulate your home to escape. Both are detrimental to energy efficiency.
The reason window seals can fail is because they are exposed to extremes of temperature, humidity and pressure. These changes cause the glass to expand and contract, which places a lot of pressure on seals over time. This is also a possibility in the case of pets or children who accidentally smash into your windows.
When your window seal breaks, it's a good idea to have the problem investigated by a professional as quickly as you can. If you wait too long and the argon or krypton gas may escape completely, and this can significantly decrease the insulation properties of your window.
Another sign that your seal is failing is seeing fogging in between your window frames. It is possible to defog your windows however, it is recommended to call a professional out and reseal the window.
A technician will remove the existing seal and clean the glass. They will install the new seal once windows are sealed. The technician will take apart the sash, if needed then reassemble it and replace the IGU (insulated unit) if necessary. Then, they will insert argon or krypton into the gap between the panes and seal around the IGU to ensure a watertight fit. You can buy kits that claim to help homeowners in this process. These products have received mixed reviews, but we recommend that you leave this task to professionals.
Condensation
Condensation is among the most frequently encountered issues with double glazing, especially in older buildings. It happens when the air inside a house has a higher dewpoint and is warmer than the glass, which causes moisture to form. It is more likely to occur at the night or during the early morning hours when temperatures are lowest.
Fortunately condensation in double-glazed windows is easily repaired and typically does not need replacement of the entire window or door. The'spacer bar' that is located between the two glass panes in the majority of double glazing is filled with desiccant which is extremely absorbent and absorbs any moisture that comes into the 'air gap' void. If this spacer bar is filled with moisture, it could get into the frame of the window where condensation forms.
You should also be aware that double-glazed windows are covered by a guarantee. This means that you are able to contact the company that installed them. They will investigate the issue and replace any units or seals that are defective. Do not attempt to alter the units, because this could cause damage to your warranty.

It is also a good idea to wipe down frames with a damp cloth to see if this can help, especially since extreme weather can cause them to expand or shrink and this could make them difficult open.
Draughts
The gap between the frame and the wall allows draughts into your home, which could be chilly, and also increase your energy costs. Draught proofing can help by closing the gaps and increasing insulation. It's worth getting estimates from several firms for this service as it can vary, but an honest company should stand behind their work.

They can provide you with guidance on the most cost-effective options for your property. They may even be able to match your existing frames, meaning you don't have to replace everything.
Smudging
This is the first indication that double glazing is experiencing an issue, and it's easy to fix. The condensation that is emitted from the inside of the window becomes trapped between the two panes, and then appears as smudges or droplets of water on the outside of your windows. Untreated, this could lead to mould and damage to the frames and sills. Inhaling mold spores could also cause health issues.

Mist
Condensation on the exterior of your double glazed windows is nothing to be concerned about, since it's a sign that your windows are functioning properly, keeping moisture and damp from your home. Mist inside your windows is a much more serious issue that indicates one or more seals are damaged.
To make the double-glazed window water-resistant and airtight, the gap between the two panes must be sealed with the gas argon. If the glass is misted it could mean that the argon gas has been damaged or the seal was damaged. It could also be a sign of poor installation because the window might have been damaged during the fitting process, or the sealant has worn away over time.
Many companies claim that they can repair misted double-glazed windows by drilling small holes in the glass, and then pumping chemicals into these holes to absorb water vapour from the inside. This is a good solution for many, but it's important to be aware that there are limitations to what can be fixed.
Sometimes replacement is the best choice. This is particularly true when there are significant damages. Broken panes, rot or severe damage could mean that the window unit is no longer functional and should be replaced with something newer and more energy efficient. In these instances an appointment with a professional is advised to determine the best course of action.
