Double Glazed Window Repairs
Double glazing is an investment that is worth it, but can be frustrating when it fails to perform. Most problems can be repaired and you do not have to replace windows or doors.
Double glazed windows consist of two glass panels that are separated by a thin gap that is filled with insulating gas such as argon or krypton. This increases the efficiency of a window's heating.
Broken panes
Double-pane windows are resistant to breaking than single-pane glass, they may break or shatter. It is crucial to repair any broken panes in double glazing as quickly as possible in order to avoid moisture and energy loss.
You can opt for an immediate repair or a more extensive epoxy fix based on the degree of the crack. A temporary repair can keep cracks from spreading and protect against cold and rain. A more extensive repair can make the crack stronger and provide more secure seal.
To replace a double-pane damaged window, remove the frame and place it on an un-slip surface. Install a grid of duct tap over the pane in order to stop glass fragments from falling during removal. After the tape has been installed, remove the old double-pane glass out of the frame. Then, use a wirebrush to clean the grooves and rabbets. You can also vacuum or wipe them with a damp cloth. Remove the wood moldings if necessary and scrape off any metal glazing points or putty before installing the new pane. Apply silicone caulk in the rabbets and grooves to ensure a snug fit.
If you're planning to repair a cracked window yourself, start by sanding the rabbet until it's smooth and free of paint or gunk. You can also use a heating gun to soften any putty or glazing points. Once the rabbet has been cleaned and dried, you can use a putty knife to press ropes into place. Make sure that the putty is of an even thickness, and that it presses evenly against the glass and frame.
If you're looking for a long-term fix an epoxy repair is a better option over replacing it. This is more expensive and has a longer waiting period, but can be more appealing. It also lasts longer than the temporary fix.
Condensation
Condensation is a frequent issue with double-glazed windows however that doesn't mean they are defective. The fact that your windows show condensation is a good indication that your double glazing is doing what it's supposed do, keeping the cold out and letting warmth in.

The cause of internal condensation is usually too much humidity or low temperatures in the room. This results in cold surfaces, like windows which attract moisture that is high in dewpoint (the temperature at which water turns into liquid). The steam from kettles, showers and hot pots as well as cookers can also create humidity in kitchens and bathrooms.
To prevent condensation, try not to hang wet clothing near your windows and always make sure that your uPVC frames are able to provide ample air circulation to stop the build-up of moisture. It is also important to make sure that your double-glazed windows are properly insulated and fitted with the correct gap (6mm is ideal) to maximize energy efficiency. It is also possible to add one-way air vents on your windows to increase the insulation. If you're still experiencing condensation, there's an issue with the gaskets or seals and this is an issue that requires the expertise of a professional.

Smudging
Double-glazed windows consist of two separate panes, with an air spacer or dense gas in between. This creates an effective seal that stops heat from venting out through the frame. They are a great method to save energy and decrease your carbon footprint. Double glazing may have many issues that could affect its performance and life span.

To address Repair My Windows And Doors will make tiny holes to vent any moisture that is trapped between the glass panes and the rest of the window. After the moisture has been removed, a new antifog coating is put on and the window is sealed. Sometimes the window will require removal however, in the majority of instances, it can be done within the home.
Mist
Double glazing that has been in use for a long time may be prone to mist, especially if it occurs both inside and outside the window. This is due to a failure of the seal designed to keep moisture and air between the two panes. During the manufacture of double-glazed units this seal is created by sealing both panes with an airtight polysulphide or butyl seal around the edges of the glass and the spacer bar. This seal is designed to prevent the window from leaking and to provide insulation. If you have misted double glazed windows, it may be difficult to take off and clean up, as you'll have to break through the seal to clean.
The problem with mist is that it allows moisture to get in, which then causes condensation between the glass panes. The reason for this is that there is a big difference in temperature between the interior and exterior surfaces of the glass. The moisture is encased within the gaps, resulting in the appearance of milky. This can be very unattractive, and can be difficult to remove.
There are many companies that claim that they can fix your double glazed windows that are misting by drilling holes into the unit and injecting chemicals through the holes which then absorbs the moisture within. However, this isn't a permanent solution to the problem and it's much easier to replace the entire double-glazed unit if suffering from misting.
The easiest method to avoid misty double glazing is making sure you have adequate ventilation and cleaning your windows regularly. It's also a good idea to use extractor fans in bathrooms and kitchens, and wipe down windows with an damp cloth to minimize the build-up of moisture. If you can't avoid the issue, we suggest that you replace your double-glazed windows with A-rated units to improve energy efficiency.
