Double Glazing Windows Repairs
Double glazing refers to the panes of glass that are placed inside frames for windows or walls opening. The window glazing may be damaged and require repairs.
If you've noticed condensation between your windows, a noticeable draft, or hinges or handles become difficult to open, it is an indication that your double glazing needs repair. This repair usually requires a reseal of the entire unit.
Broken Panes
Double glazed windows consist of two glass panes, with an air gap which is filled with inert gases like argon or krypton. This helps to keep the heat in your home, while also preventing cold drafts and moisture from escaping. Sometimes, windows will become damaged, and the whole window may require replacement. If you notice cracks or chips in the window it is important to contact the company who supplied you with the double glazing immediately to inform them of the issue and inquire about a repair.
It is possible to fix damaged glass with just a few steps, however it is not recommended unless you are experienced in DIY. First of all you'll require gloves and carefully remove the broken pane. If it's cracked, press strips of masking tape across the cracked areas in a crisscross pattern. This will prevent the cracks from becoming worse over time, especially during the winter. It is also a good idea to cover your work surface with newspaper in the event that any broken pieces fall off. Once the broken pane is removed then use a putty blade to scrape away any glazing putty and glazed window seal. Remove the glazing points by using pliers. Finally, paint the bare wood with a fast-drying primer.
If you can purchase a new replacement pane take measurements of the length and width of the channel with a tape measure. Subtract 1/8" from both measurements to take into account the slight movement of the replacement pane. Then, roll a short rope of glazing compound into the channels that have grooves and slide the replacement glass into the grooves. Tap the glass gently using an hammer each 6" or 8" to aid in setting it in its place. Be careful not to break it.
If you have a double-glazing warranty, it's worth trying to use this in order to avoid the expense of a complete replacement window. In general, the warranty will cover both the cost of the parts and labor. You should verify the terms because they may differ from company to company.
Foggy Glass
Condensation between the panes of your double glazing can result in foggy glass. This could be caused by various reasons including temperature fluctuations, incorrectly installed frames, or even the deteriorating seals.
In the majority of cases, double glazing installers can fix this problem quickly and easily. It's important to contact the company that installed your windows when you discover an issue, and write a note. This will make it easier in the event that you need to contact them later on. It could also be extremely helpful in the event that the issue is covered by your warranty or guarantee.
It is possible to resolve the problem by replacing the gasket seals. This won't require you to replace the entire window unit, and will make your home more energy efficient. The window glazier will first remove the clips or retaining strips that hold the IGU and then employ a saw to cut away the old sealant.
Then, they'll build or purchase an IGU replacement to fit the frame, and use specific sealants to ensure that it's air- and water-tight. Once they're finished, they'll reinstall retaining clips or strip them and apply more sealant.
If you're lucky, the misting could end after this. However, it's important to ensure your frames are ventilated properly so that water doesn't get trapped within your ceilings and walls.
Double glazing owners have also reported that their windows and doors are difficult to open or close. This may be due to extreme weather conditions, or the frame has become sagging over time and isn't flush with the rest your home. If this is the case, you can try wiping down the frames using cold water to shrink them slightly. However, this will not resolve the issue completely. If you're still unable to solve the problem, you may require a professional to replace the frames.
Condensation
Condensation happens when the insulating gases in double-glazed windows fail to hold their place leaving air and moisture between the panes. This is a common issue during winter, when humidity levels are typically higher, though it can occur at other times of the year too. Moisture can cause mildew and mould to form around window frames, sealants, and sills. This is not only unsightly, but it's extremely harmful to your health. A window specialist can often reseal condensation to reduce moisture and prevent the build-up of moisture in your home.
Window gaskets are an important part of any double-glazed window or door. Gaskets are used to seal the air-tight space between the window glass to keep drafts as well as heat, moisture, and drafts from entering or leaving your home. These gaskets may shrink or become brittle as a result of variations in temperature as well as weather conditions and ageing. You might notice condensation on your double-glazed windows or doors.
This can be repaired, but will require replacing the "sandwich" (thermo-pane & glass) inside your double-glazing window. If you do not have the appropriate tools for the job, it is recommended that you get a professional to seal your double-glazed windows.
Mist in your double-glazed windows is a common issue that can be a challenge to fix. This is a sign that the factory vacuum seal has failed, and there is no way to get air out or in the sandwich.
Professionals will reseal your windows with the same method they would employ to solve the issue of condensation or fog. This typically involves removing the thermo-pane sandwich, spraying it with a cleaning solution, then sucking out the old sealant. It is vital to take measurements of the sandwich in terms of length, width and thickening. This will ensure that the new one is perfectly sized and that the new seal is drawn.
This can be a tricky job that requires special tools that aren't commonly found in DIY stores. It is recommended to leave this task to professionals, because faulty seals could result in damp and mold in your home. This could be costly and dangerous to your health.
Water Leaks
If you notice water getting into your double glazing windows, it is important to act fast. A small leak can quickly become a major issue in the event that it is not addressed promptly.
Often times the window frame itself could be the cause. Verify that the sill, the flat base of the window frame, is pitched so that water is able to drain away from your home and not into the frame. If you notice that the sill pan is not pitched correctly or you can see water in the wood, you should consult an expert in double-glazing repair.
Another common cause of water leaks is a damaged window seal. This can be caused by age, damage or weather. This isn't an easy thing to fix, and is generally best left to the experts.
A window seal that is damaged can let air through the windows, making it less efficient in energy use. This also allows cold air to enter your home in the winter and hot air to escape in summer. This can result in costly cooling and heating costs.
The simplest method to fix this is to apply a new layer of caulking. While it is possible for people with a few DIY skills to do this on their own it is generally much more efficient to let a double-glazing specialist take care of it for you. In this way, you'll have a guarantee and peace of mind knowing that the job is done correctly.
