Double Glazed Windows Repairs
If your double-glazed windows are difficult to open or have a mist between the panes this could be an indication of faulty seals. If this is the case, it will be worthwhile to arrange for them to be fixed.
This is a much cheaper option than replacing the windows. This type of repair requires very specific tools and equipment, so it's recommended to leave this to professionals.
Seals that have been damaged
Window seals hold the gas argon or Krypton between panes of glass in double or triple-pane windows, and they can wear out as time passes. A broken seal allows air from outside to enter, and the argon gas that insulates your home to escape. Both of these are detrimental to energy efficiency.
Window seals are susceptible to damage due to extremes in humidity, temperature and pressure. These changes cause your window glass to expand and shrink, which puts lots of pressure on the seals over time. This is also a possibility in the case of pets or children that accidentally hit your windows.
If your window seal breaks it is recommended to have the issue addressed by a specialist as soon as possible. If you wait too much and the argon gas or krypton gas could escape completely and decrease the insulation properties of your window.
Another common sign that the seal isn't working is noticing fogging in between your window frames. It is possible to defog your windows however, it is recommended to have a specialist come out and seal the window.
If you are having your windows resealed, a technician will remove the old seal, clean the panes and put in the new seal. This will require disassembling the sash, if needed and then reassembling it, and replacing the IGU (insulated glass unit) in the event that it is required. Then, they'll insert argon or krypton into the gap between the panes, and seal around the IGU to ensure a watertight seal. This isn't a DIY job, but you can find some kits that claim to aid homeowners with this. These products have received mixed reviews, but we suggest that you leave this task to the professionals.
Condensation
Condensation is a potential issue when double glazing is used. This is especially true in older homes. It occurs when the air inside a house has a higher dewpoint and is warmer than the glass, causing condensation of moisture. It is more likely to occur during the night or during the early morning hours when temperatures are at their lowest.
repairing double glazing in double-glazed windows can be fixed easily, and it is not necessary to replace the entire window or door. The spacer bar located between the two glass panes in the majority of double glazing is filled with desiccant which is highly absorptive and sucks up any moisture that comes into the 'air gap' void. However, if the spacer bar becomes saturated with moisture it can begin to leak into the frame of the window which is where the condensation forms.
It is important to remember that most double-glazed windows are still covered by a guarantee and must be reported to the company who installed the windows. They will investigate and replace any seals or units that are defective. But, don't try to alter the units since this could end your warranty.

Draughts
The gap between your frame and wall can allow draughts to enter your home. This can be cold and add to the cost of energy. Draught proofing is a way of sealing the gaps and increasing insulation. It's worth getting estimates from several firms for this work as it may vary, but a good company should guarantee their work.

Over time, the frames of uPVC can become discoloured. This is usually caused by sunlight, cleaning products or the weather however if you notice a lot of dark streaks or areas that aren't clean, it might be time to get them replaced. Some companies offer replacement services while others will replace the entire frame and handle or locking mechanism. It is best to speak with your original window vendor. They can offer suggestions on the most cost-effective options for your property. They might even be in a position to match the frames you have, so you don't have to replace everything.
Smudging
This is the initial sign that double glazing has an issue, and it's simple to repair. It happens when condensation that has formed inside the window is trapped in between the two panes. It appears as smudges and droplets of water on the exterior of the windows. Leaving this untreated could lead to mould or damage to the materials of your frames and sills as well as the inhalation of mold spores for extended periods can cause health problems.

This will ensure that you're working with a reputable, qualified company that will be able to offer you top-quality service and products. Also, check out customer reviews before making an important decision. This will help you determine whether the company is suitable for your needs.
Mist
Condensation on the outside of your double glazed windows is nothing to be concerned about, as it's an indication that your windows are operating properly, keeping moisture and damp out of your home. The presence of mist in your windows is a much more serious issue and could indicate that one or more seals are damaged.
To make the double-glazed window waterproof and airtight, the gap between the two panes must be sealed with gas argon. If the glass is misted it could be because the argon gas is damaged or the seal was broken. It also indicates an inadequate installation since the window might have been damaged during the fitting process, or the sealant has worn down over time.
Many companies claim they can repair double-glazed windows that have mist by drilling tiny holes in the glass, and then pumping chemicals into these holes to absorb water vapour that is trapped inside. This is a good solution for a lot of people but it's important to know that there are limitations to what can be repaired.
There are instances when replacing the window unit is the more appropriate option, particularly when there is significant damage. Completely broken panes, extensive rot or damage could mean that the window unit is no longer functional and should be replaced with something more modern, better and more energy efficient. In these situations it is recommended to consult an expert is advised to determine the best option.
